The BMW Z4 GT3, which was officially launched and completed its first test drives at the start of March,it is already enjoying great popularity among BMW Motorsport customers. The first cars have been delivered to private BMW teams, who will prepare them for use in various national and international championships.
"The feedback on the BMW Z4 GT3 is extremely positive," says BMW Motorsport Director Mario Theissen. "This sports car rounds off our product range, and offers drivers and teams the opportunity to compete in championships in accordance with the GT3 regulations - such as the FIA GT3 European Championship, the International GT Open or the ADAC GT Masters - as well as at 24-hour endurance races." In addition, the BMW M3 GT2, the BMW 320si WTCC, which complies with Super2000 regulations, and the close-to-production BMW M3 GT4 are also available to customer teams from all over the world at BMW Motorsport Distribution.
The production model of the BMW Z4 is already impressive: with its elongated bonnet, flared wheel arches, long wheel base and narrow projections, the car boasts an unmistakable appearance. The two-seater provided BMW Motorsport engineers with a good basis for developing a close-to-production GT3 racing car.
The largest difference between production and racing car can be found under the bonnet: while the production version of the BMW Z4 is driven by a six-cylinder engine, the GT3 car is powered by a 4.0-litre eight-cylinder engine similar to the unit used in the BMW M3 GT2. This powerful heart produces over 480 bhp. Its excellent performance characteristics and good torque curve make the base engine from the production version of the BMW M3 predestined for use in motorsport.
The fitting of the V8 engine had a considerable influence on the development of the BMW Z4 GT3. Initially, design-space examinations were performed using CATIA V5 design software, in order to place the engine in the ideal position and meet racing specifications. The engineers then added all the other components.
When it comes to electronics, the private teams can look forward to innovative BMW solutions, which have already been tried and tested on the BMW M3 GT2: the modern ECU408 takes over the engine management, while the Power400 electronic control unit is responsible for controlling all the actuators. The power is transmitted through a six-speed, sequential gearbox with "Quick Shift" function.
Rims with central locking and safety clip are also included in delivery. In addition, the BMW Z4 GT3 also offers driver assistance systems such as racing ABS and traction control, which have been adopted from other cars in the customer racing range, and then further developed and modified for use in the GT3 car.
The front axle of the BMW Z4 GT3 is a completely new design, based on a series concept. It is equipped with a tubular stabiliser bar with adjustable blades. The rear axle is designed as a longitudinal link axle, as with the series version of the BMW Z4. The steel body of the car comes from the BMW Plant in Regensburg. A safety cell made of extremely rigid, precision steel tubing is then welded into the body. The engine block of the V8 engine is produced in the BMW foundry in Landshut. The BMW Plant in Dingolfing contributes the rear axle differential and drive shaft, among other things.
During the development, BMW Motorsport engineers worked hand in hand in other areas with their colleagues from series production. This allowed them to access calculations from the field of computational fluid dynamics (CFD) when designing the car's aerodynamics. Furthermore, tests were also carried out in the wind tunnel and on the BMW Group's test benches.
Front and rear wings, bonnet, roof, fender and many other components are made of carbon fibre reinforced plastics (CFRP). Using this lightweight, torsion-resistant material contributed significantly to reducing the weight of the BMW Z4 GT3 to 1,200 kilograms.
As with all cars in the BMW customer racing range, the emphasis was also put on cost-efficiency when developing the BMW Z4 GT3. As a result, the car offers a very good cost/performance ratio and gives private teams the opportunity to participate in affordable motorsport at the highest level.
The BMW Z4 GT3 is available as a racing car at a cost of 298,000 Euros (plus VAT).
2011 BMW X5 will write the latest chapter in the story of the world's first Sports Activity Vehicle. Originally launched for the 2000 model year in late 1999, the BMW X5 permanently changed the automotive landscape. It proved that the driving dynamics, responsiveness, and linear control signature to every BMW could be compatible with utility, versatility, and other-roads capability. For 2011, the BMW X5 models are enhanced with new powertrains and updated design. The new BMW X5 will make its North American debut at the New York International Auto Show.
Innovative new design elements and powertrains are the result of over 4,000 new parts created by BMW designers and engineers for the 2011 BMW X5. Two of the X5's powertrains will be all-new for 2011, creating the new BMW X5 xDrive50i and BMW X5 xDrive35i, in addition to the familiar BMW Advanced Diesel X5 xDrive35d. All models receive a design update that enhances the brilliant focus and aesthetic appearance of the X5 brand.
Fresh Design. Well-Balanced Proportions.
The body design of the 2011 BMW X5 is characterized by well-balanced proportions that accentuate the vehicle's powerful presence and agility. A long wheelbase, short front and rear body overhangs, and large light-alloy wheels provide a visual balance between the front and rear of the vehicle. Square-shaped, carefully flared wheel arches hint at the BMW X5's all-wheel drive traction and other-roads capability. The body lines sweep upwards from the front and rear wheels, communicating BMW's near-perfect 50-50 front-rear weight distribution which is so essential to the BMW X5's legendary driving dynamic.
The sides of the BMW X5 are elegantly stretched though the strong horizontal lines of each side. The surface of the hood flows seamlessly into the waiseline, while the prominent, gently inclined contour line at the door handle level extends from the front wheel arches to the rear of the vehicle. These character lines symbolize power, stability, and presence.
With its distinctively contoured hood, large BMW kidney grille and dual round headlights, the new BMW X5 boasts an expressive front end that symbolizes power and presence. The newest interpretation of the BMW X5's look is led by the redesign of the front fascia and position of the standard foglamps. Due to an increase in the number of elements painted body color, the front end gives the impression of being lower. At the same time, the increased size of both the central and outer air intakes hint at the boosted engine output. The black trim at the bottom edge of the body is now considerably narrower. A matte-finished silver protection plate extends across the entire width of the central air intake, emphasizing the muscular features of the SAV, and accentuates the new BMW X5's character.
The dual round Xenon Adaptive headlights and foglamps are now situated higher and closer to the kidney grille. The BMW X5's new headlight fixtures emphasize high quality and sporting intentions. BMW's signature corona rings serve as position lights and daytime driving lights.
The newly conceived rear apron matches the graphic structure of the front end, while the intricately designed surrounds of the dual exhaust pipes are painted in body color to underline the BMW X5's premium character. In the center, a matte-finished silver protection element emphasizes strength and durability suitable for other-roads use.
Above the rear bumper, the rear of the new X5 is divided by parallel horizontal lines. The result is an accentuation of the width, highlighting the vehicle's athletic capabilities. The L-shaped taillight fixtures, each with two LED light banks, create the BMW-signature nighttime appearance of the rear end.
A choice of new body colors provides further visual enhancements. The metallic colors Deep Sea Blue, Platinum Grey, and Sparkling Bronze are now available for the BMW X5. Inside, the available Nevada Leather can be chosen in stunning new Oyster or Cinnamon Brown colors in addition to the familiar Sand Beige, and Black, and matte Satin Silver interior trim strips are added if the owner does not select from the available Brushed Aluminum, Dark Bamboo, Light Poplar, or Burl Walnut wood trims.
BMW X5 xDrive50i: BMW's Twin-Turbocharged V-8.
The new BMW X5 xDrive50i takes its place as the flagship of the X5 family, yielding 400 horsepower at 5,500 rpm and 450 lb-ft of torque at 1,750 - 4,500 rpm from its twin-turbocharged 4.4 liter V-8 engine. Introduced in the BMW X6 in Spring of 2008, this all-aluminum V-8 features High Precision direct fuel injection, "reverse-flow" architecture for revolutionary responsiveness and packaging, and BMW' s VANOS variable valve timing technology. Together, these features create what may be the perfect balance between high fuel efficiency, low emissions, and the dominant, dynamic performance expected of a BMW V-8. The 0-60 mph sprint is accomplished in 5.3 seconds.
BMW X5 xDrive50i starts at $59,275 including Destination & Handling.
As part of the V-8 engine's reverse-flow architecture, the twin turbochargers are situated in the valley of the engine's "V" and exhale separately into two catalytic converters which are located on top of the engine and exit aftward into the large stainless-steel exhaust system via downpipes on either side of the new 8-speed automatic transmission. The exhaust streams remain separated until they meet in the large muffler at the rear of the vehicle and exit through two large, trapezoidal exhaust tips.
BMW X5 xDrive35i: BMW's Turbocharged Inline-6 with Valvetronic.
BMW X5 xDrive 35i receives a brand new inline-6 gasoline engine, internally dubbed "N55." The new engine features the same 3.0-liter displacement and 300 horsepower output of its predecessor (the "N54"), but features a single twin-scroll turbocharger in place of the previous twin, low-mass turbocharger units. Furthermore, the new inline-6 of the BMW X5 xDrive35i is the first BMW inline-6 to combine BMW's revolutionary Valvetronic throttle-less intake technology, High Precision direct fuel injection, and turbocharging. The result of combining this new inline-6 with the new 8-speed automatic is an BMW X5 with incredibly spontaneous responsiveness, exceptional power, and remarkable efficiency. The new BMW X5 xDrive35i will perform the 0-60mph sprint in 6.4 seconds, coincidentally on the same pace as the outgoing V-8 powered BMW X5 xDrive48i.
For the 2011 model year, BMW has made the X5 xDrive35i available in two additional trim levels: "Premium" and "Sports Activity."
The essential BMW X5 xDrive35i has an MSRP of $46,675 including Destination & Handling, and includes a popular profile of standard equipment often specified by BMW X5 customers, including BMW's Xenon Adaptive headlights, Rain Sensor with automatic headlight control, HD Radio, automatic climate control, foglights, 18" light alloy wheels, cruise control, and anti-theft alarm system. A Convenience Package is optional and adds the large panoramic moonroof, auto-dimming mirrors, Dark Burl Walnut, Bamboo, or Light Poplar wood interior trim, BMW Ambiance Lighting, and BMW Assist with Bluetooth. Stand alone options include rear side window shades, Navigation system with Real Time Traffic Information and Voice Command, satellite radio with 1-year subscription, and an iPod / USB adapter interface.
The BMW X5 xDrive35i Premium has an MSRP of $52,475 including Destination & Handling and includes a boosted profile of standard equipment, such as 19" light alloy wheels, roof rails and panoramic moonroof, power adjustable steering column, iPod / USB adapter interface, and privacy glass. Best of all, it includes standard Nevada Leather. In addition, buyers of the Premium model may choose up to four packages, including the Active Ventilated Seat Package, Convenience Package, Cold Weather Package, and Technology Package. Each package includes a raft of focused features that enhance comfort and convenience, allowing buyers to better customize the BMW X5 to personal taste. Third Row seating, which enables the BMW X5 to accommodate up to 7 passengers, also becomes available on this model.
The BMW X5 xDrive35i Sport Activity has an MSRP of $54,975 including Destination & Handling and includes even more standard equipment than the Premium model, such as 20" light alloy wheels, sport seats, Shadowline exterior trim, and Anthracite headliner. In addition to the packages available on the Premium model, customers may add the popular M Sport Package to the BMW X5 xDrive35i Sport Activity model. The M Sport Package includes 20" wheels with performance tires, the Adaptive Drive system, aluminum roof rails, M door sill plates, M driver footrest, M steering wheel, M aerodynamic enhancements, and increased top speed limiter (150 mph).
New 8-speed Automatic Transmission with Steptronic.
On both new gasoline models of the BMW X5, sending the newfound power to the standard xDrive intelligent all-wheel drive system is BMW's new 8-speed automatic transmission with Steptronic control. The new 8-speed transmission is standard in the BMW X5 xDrive50i and X5 xDrive35i, and raises the industry standard for compactness, efficiency, and gear selection. The new transmission weighs no more than its 6-speed predecessor, yet offers closer ratios in the lower gears for improved acceleration and two additional "tall" gears for relaxed, efficient cruising. BMW's 8-speed automatic was introduced on the 5-Series Gran Turismo and 760Li Sedan in the fall of 2009.
Using the console-mounted e-shifter, the BMW X5 driver chooses from three shifting programs: Drive, Drive Sport, and Manual. In Manual mode, the driver selects from the eight forward gear ratios via the + / - action of the shifter (push forward to downshift; pull back to upshift). At any speed, Neutral is easily selected via a forward push of the selector from Drive and, when at a standstill, Park is selected by depressing the "P" button atop the shifter, or by pushing the Engine Start-Stop button (doing so will also stop the engine).
BMW's Brake Energy Regeneration system is also fitted to the gasoline X5 models. It incorporates a special deep-cycle Glass Mat battery with programmed alternator disengagement so that, most of the time, the vehicle's battery is only charged while the vehicle is coasting or braking. Over time, the Brake Energy Regeneration system can save 1-2% on fuel consumption. Brake Energy Regeneration is another feature in BMW's EfficientDynamics portfolio of small features and adjustments which have a cumulative effect on the efficiency-performance balance of each BMW vehicle.
BMW X5 xDrive35d: Maintaining the Benchmark with BMW Advanced Diesel Technology.
The BMW Advanced Diesel X5 xDrive35d was introduced to the United States as a 2009 model, and despite increased competition remains the fastest, most fuel efficient diesel-powered vehicle in its class. The huge torque output of 425 lb-ft. at 1750-2250 rpm speaks for itself; BMW X5 xDrive35d drivers will marvel at this engine's robust response at low to medium speeds. The peak power output of 265 hp also makes an impact, as does the resulting 0-60-mph time of 6.9 seconds. It returns EPA mileage estimates of 19 mpg city and 26 highway.
For the 2011 model, BMW has made no changes to the award-winning BMW Advanced Diesel powertrain, but rather has focused efforts to ensure the BMW X5 xDrive35d benefits from the latest design updates to the X5 family. Despite the enhancements for the new model year, MSRP for this model remains $52,175 including Destination & Handling.
BMW Advanced Diesel with BluePerformance optimizes emission management by incorporating an oxidation catalyst placed close to the engine, a diesel particulate filter housed in the same unit, and an SCR catalyst with urea injection. Apart from filtering out even the smallest particles from the flow of exhaust gases, this combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea referred to as Diesel Exhaust Fluid. Into the exhaust stream. The ammonia (NH3) generated in this process within the SCR catalyst subsequently converts the nitric oxides (NO and, respectively, NO2) in the exhaust gas into environmentally compatible nitrogen (N2) and water vapor (H2O).
BMW has developed a two-tank system for DEF ensuring convenient use of this new technology with all the benefits and ease required by the customer: The amount of DEF required in each case is drawn from the active tank comprising approximately 1.6 gallons by means of a dosage pump. And since the urea solution would freeze at a temperature of 12.2o F (-11oC), this active tank, as well as the dosage pipes are heated.
What do you get when you combine a BMW R1200R and a Buell XB12? The D1200R! A former employee of Lamborghini by the name of Pablo González de Chaves Fernández has turned his attention from four wheels to two and has begun creating innovative design improvements to existing motorcycles with the help of Juan Elizalde Bertrand. This project stems from a patent that does away with the inefficient steering movements in motorcycles with traditional forks. Their system makes steering direct with a one-to-one turning ratio that offers improved stability and allegedly prevents front end dives during mid-corner braking.
While the bike may be unrecognizable to the untrained eye, the power plant of the D1200R is unmistakably a 1200cc BMW boxer engine. The braking system from a Buell XB12 was installed and oscillating suspension arms were mounted in order to allow small adjustments of the rake angle. Steering inputs also utilize a telescopic tube transmitted through torsion scissors. Much of the aesthetics of the motorcycle were modified, including the suspension, rear cowling, Carbon fiber tank cover and flush LED lighting. The overall goal of this project was to improve the appearance and performance of an already impressive performer. Does it succeed? You be the judge.
Leading the way with concept studies – a BMW Motorrad tradition. BMW Motorrad has a tradition of coming up with new ways and ideas when it comes to motorcycling. Fascinating studies and designs have been produced in the past using ideas which then found their way into serial production. But studies by BMW Motorrad are about more than just trying to develop a motorcycle which has not existed in a given form before. In addition to functions and quality, BMW developers focus on the emotional component – the connection between man and motorcycle. The guiding principle is that a motorcycle should not just function perfectly but should also appeal to all the riders’ senses simultaneously, arouse an emotional response in him and fill him with enthusiasm at every moment – when stationary and when moving, as a whole and in its detail. In short: it has to light the fire. Emotion through interaction – individualisation made-to-measure.
The study Lo Rider does not fit into any of the classic motorcycle segments – and it is not supposed to. It combines the latest technical attributes of high performance sports motorcycles with the traditional, classic principles of motorcycle construction. State-of-the-art chassis components from sports motorcycle construction such as the powerful upside-down fork, 6-piston brake calipers with real bite and wide 17-inch tyres are combined with style defining elements of motorcycle construction from the fifties and sixties. For example, with the exhaust system in a more traditional lower position in side pipe style creates a classic roadster or cool cruiser look, while a raised exhaust system is reminiscent of legendary racing machines or typical scrambler models of days gone by. Together with a range of variously designed seat concepts, also based on styles of the fifties and sixties, as well as differing paint finish versions, the BMW Lo Rider offers the motorcycle fan a wealth of possibilities by means of which to interpret the roadster theme in a highly individual way according to his own personal taste founded on a single basic motorcycle. In fact the Lo Rider gives the creativity of its rider almost completely free rein. Chassis and engine – state-of-the-art technology based on classic principles.
In terms of tyre dimensions, the 17-inch wheels represent the current state of the art for sports motorcycles, though with their chrome wire spokes, black hubs and steel rims they ingeniously echo the characteristic stylistic elements and fl air of a past era. By contrast, contemporary technology and a high level of riding dynamics is provided by elements such as the high performance dual brake disk with powerful 6-piston calipers, together with wave brake discs borrowed from motor racing at the front and the single disc brake at the rear. In terms of its engine, the Lo Rider also relies on technology which is both contemporary and full of character – the legendary, highly responsive BMW fl at twin “Boxer” engine. For 85 years, the construction principle of this engine has stood for unmistakable, authentic design, a full torque curve and unique sound and power. In its current version with an output of over 100 bhp, overhead camshafts, electronic fuel injection and exhaust gas purification, the powerful response of this dynamic and distinctive 2-cylinder is simply perfect for the BMW Lo Rider. The customer as designer – individual designs and paint finishes.
The concept study Lo Rider is mainly focused on the two essential component groups of a motorcycle, the engine and the chassis. Any superfluous decoration is omitted. Instead, variable components such as the exhaust system, seat, headlamp unit and paint finishes determine the bike’s outward appearance, at the same time defining its conceptual style. The combination of these classic and modern components is entirely subject to the personal taste of the customer. For example, he can initially express the dominating character of the BMW Lo Rider through the placement of the exhaust system, creating either a sporty style or opting for a more roadster like look by having it lowered. A very sporty effect is created by the classic perch seat made of aluminium sheet metal, while the simple single seat reduced to the absolute minimum will appeal to purist motorcycle fans. The single seat can also be optionally extended to include a pillion passenger module. The specification laid down for the development team led by David Robb, Head of Design Development at BMW Motorrad, was that all the conceivable combination options of these components should produce different end results but that the bike should always retain a rounded, coherent character in itself. Whether with a raised or lowered exhaust system, with sporty perch seat or seat bench for one or two people: the Lo Rider comes over differently every time but always makes an impression.
The same applies to the selection options in creating the front section of the Lo Rider. With their aggressive, modern design, the vertically arranged dual headlamps give it a touch of the streetfighter, while the classic, semicircular headlamp provides an echo of past times. Once again, the same principle applies.
however different the styles thus created might be, they always have a consistent emotional appeal for the rider. Further possibilities for individual design are available to the customer in the choice of paint finish. There are four different colours available for the fuel tank, and with the three different paint finishes for the engine casing this allows the customer to create a very distinctive, personal look, defining the character of the Lo Rider as anything from refined to sporty. These always harmonize perfectly with the deliberately classic, high-quality aluminium parts such as fuel tank trim, seat holder and wing struts. Different styles can also be created with the front and rear wings which are available either in black or chrome finish.
BMW Announces Availability of the HP2 Sport in the U.S.A.May 9, 2008 - The BMW HP2 Sport has arrived at U.S. BMW motorcycle retailers. The same high-performance sport bike that Richard Cooper and Brian Parriott rode to fifth and sixth place finishes in last month's Daytona 200 is now available in limited supplies for serious motorcycle enthusiasts. The high-performance (HP) two (2)-cylinder Boxer -- customized to meet the requirements of the ambitious sport rider -- has a manufacturer's suggested retail price of $25,375 (excluding taxes, license, options, and handling charge).
The sportiest, most powerful and lightest Boxer ever manufactured, the HP2 Sport features numerous exclusive details, previously restricted to racing, that were never before seen in series production vehicles. Technology such as the self-supporting and aerodynamically optimized fairings made completely of carbon fiber, the quick shifter, a dashboard similar to that used in the MotoGP, the forged aluminum wheels and brakes with radially bolted calipers make the HP2 unmistakably athletic on both country roads or the racing circuit.
The most striking difference between the BMW HP2 Sport from the earlier endurance racing Boxer is the brand new cylinder heads: each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than those on the BMW R 1200 S.
Further modifications, such as the flow-optimized intake and outlet, new forged pistons and adapted connecting rod, help the engine to achieve the necessary higher output compared to the basic engine. A new stainless steel exhaust system is placed below the engine for the first time, keeping the lower area of the motorcycle extremely slim for greater freedom of movement for a "hanging off" riding position.
Although designed for racing prowess, the BMW HP2 Sport does not forego the safety benefits of ABS. A sophisticated anti-blocking system, specially adapted to the HP2 Sport, is available as an option and is configured so that it can be deactivated for the racetrack.
Following the BMW Motorrad Motorsport design, the HP2 Sport features white lacquering on the windshield, rear, mudguard and side cover. The engine spoiler carries the two-tone "HP2" lettering; and the lattice frame and wheels are lacquered in the BMW Motorrad color of Motorsport Blue.
BMW Announces Pricing for the HP2 SportFebruary 9, 2008 - Boxer fans, reach for your checkbooks! The BMW HP2 Sport, arriving soon at US BMW motorcycle retailers, will have a manufacturer's suggested retail price of $25,375 (excluding taxes, license, options, and handling charge) and a destination charge of $495.
The high-performance (HP) two (2)-cylinder Boxer is the third motorcycle in the HP model range customized to meet the requirements of the ambitious sport rider.
The sportiest, most powerful and lightest Boxer ever manufactured, the HP2 Sport follows in the footsteps of the BMW HP2 Enduro and the HP2 Megamoto. It features numerous exclusive details, previously restricted to racing, that were never before seen in series production BMWs. Technology such as the self-supporting and aerodynamically optimized fairings made completely of CFK, the gear shift assistant, a dashboard similar to that used in the MotoGP, the forged aluminum wheels and brakes with radially mounted calipers make the HP2 unmistakably athletic on both country roads and race tracks.

1. Concept, Requirements and FeaturesThe dream of many Boxer fans has come true: With the new BMW HP2 Sport, BMW Motorrad is putting the sportiest, most powerful and lightest Boxer series of all times on the road.
The third model of the HP model range was designed for the ambitious sports rider and enthrals with numerous exclusive details that were previously restricted to racing, some making their first appearance in series vehicle production.
Examples of these include the self-supporting and aerodynamically optimized fairings made completely of CFK, the gear shift assistant, a dashboard like that used in the MotoGP, the forged aluminum wheels and the racing brakes with radially bolted calipers. Wherever the eye of the spectator wanders, it sees pure racing technology that delights every enthusiast. It is unmistakably athletic, a vehicle that inspires on country roads as well as on the racing circuit.
Regardless of the limits for the engine output as a result of the principle and the aerodynamic disadvantages from the cylinder configuration of a Boxer, BMW Motorrad deliberately decided to further develop this historic engine concept for a road racer with racing circuit talent. The key engine data are very respectable: the engine achieves more than 96 kW/128 hp at 8750 min–1 compared with the significantly modified engine of the BMW R 1200 S. The maximum torque lies at 115 Nm at 6000 min–1, the highest revs of the engine reaches a peak value at 9500 min–1.
Technically, the BMW HP2 Sport is based on the BMW R 1200 S. Customized to meet the requirements of the ambitious sports rider down to the last detail, the BMW HP2 Sport is however a completely independent and absolutely exceptional motorcycle. Many detailed solutions are based on the experiences gained in long-distance races.
The most striking difference of the BMW HP2 Sport from the endurance racing Boxer is the brand new cylinder heads: Each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than in the BMW R 1200 S. Further modifications such as the flow-optimized intake and outlet, new forged pistons and adapted connecting rod help the engine to achieve the necessary higher output compared to the basic engine.
The new stainless steel exhaust system is placed below the engine for the first time. This keeps the construction of the lower area of the motorcycle extremely slim, enabling great freedom of movement for the familiar ‘hanging off’ riding position, and the fitting of a CFK engine spoiler is advantageous to the aero-dynamics. An inimitable boxer sound with new acoustic quality is generated by the exhaust system and the striking design of the rear silencer is impressive.
Another exclusive racing feature is the gearshift assistant together with the narrow ratios of the 6-speed gearbox to enable fast gear changes without having to ease off the gas and operate the clutch. This technology is offered for the first time in a series vehicle.
In order to adapt the gearshift pattern for the racing circuit, a suitable replacement pressure sensor is available as special equipment if necessary. The fully adjustable Öhlins sports chassis also has a Brembo monoblock brake system with radially mounted, four-piston fixed calipers at the front.
Optimum ergonomics are ensured by the adjustable forged aluminum footrests, the adjustable stock handlebar and the Magura brake levers with radial mounted brake actuators. The series dashboard that comes directly from MotoGP sport provides the rider with important information and can also deliver lap times plus other racing relevant data as well as the usual displays (see Chap. 3). Attention was paid consistently to the lightweight construction of all components. This includes not only the self-supporting front fairing and the likewise self-supporting carbon rear or the weight-optimized forged wheels, but also hidden details such as the lightweight generator from the racing world. That’s how it was possible to reduce the unladen weight of the HP2 Sport to DIN standard with full tank (90%) to 199 kilos. The dry weight is a mere 178 kilos.
The interplay of variable ergonomic design, increased engine output and the favorable centre of gravity of the Boxer guarantees superb handling and racing potential. Even if racing fascination is clearly at the forefront of the BMW HP2 Sport, it does not have to forego the safety design feature of ABS.
The sophisticated anti-blocking system specially adapted to the HP2 Sport is available as an option and is configured so it can be switched off for the racetrack.
The market introduction of the BMW HP2 Sport is scheduled for 2008. 2. Model Designation and Marque“HP” is the abbreviation for “High Performance” and the “2” in the model designation of this supremely sporty BMW describes the two-cylinder Boxer engine. The term “High Performance” stands symbolically for the sporting performance idea, the achievement potential of the entire vehicle.
“High Performance” – that is the skilful harmonization of all the individual components into a convincing whole that is more than the sum of the individual parts. It is the synonym for a well thought-out overall design and perfection right down to the last detail, for the very best driving characteristics and pure, unadulterated riding pleasure. It goes without saying that “HP” also stands for the prestige connected with an exceptionally high-quality and exclusive vehicle.
After the HP2 Enduro and the HP2 Megamoto, the HP2 Sport is the third representative of an independent motorcycle category from BMW fitted with the historic Boxer engine. All the HP2 motorcycles mentioned use the technical basis of production vehicles, but are clearly differentiated by an uncompromising interpretation of their actual purpose through a conspicuous and emphatically resolute sports orientation and exclusive product features.These exceptional motorcycles are developed with great passion by small teams of professionals. The special team structure guarantees that the many years of experience of the development engineers, their grasp of the essential, personal know-how and “feeling” have a direct influence on the product.
At the same time these engineers make use of the most modern development and simulation tools plus all the technical facilities that BMW as a whole has to offer. This symbiosis of high-tech and professional skill is what distinguishes the unique appeal of the HP motorcycles.
That’s why high performance motorcycles from BMW are something very special; they are exclusive and authentic and will remain greatly sought after.
3. Development, Technical Highlights and DesignThe new BMW HP2 Sport extends the HP model range of BMW Motorrad.
It is a descendant of the BMW R 1200 S. Apart from established concepts such as the BMW Motorrad Telelever and EVO Paralever as well as the cardan shaft drive, almost all components were newly developed or at least modified to a large extent.
Weight saving, increased performance plus the uncompromising sporty configuration was top of the agenda in the list of requirements for the development engineers.
A dedicated specialist team of veteran racing motorcyclists, engineers and mechanics, whose pulse quickens for the Boxer and who have also devoted themselves to motor sport in their private lives, developed this new model for BMW Motorrad. Experiences that the BMW Motorrad motor sport team had collected with the Boxer racing motorcycle – including a number of races in the endurance world championship of 2007 – were also incorporated.DOHC cylinder heads, valve actuated by drag leverA complete redesign of the cylinder heads allowed the Boxer to reach higher revs. Extensive tests in endurance events followed in addition to the usual tests. Double overhead chain driven camshafts (DOHC) and valves actuated by very light drag lever now enable top revs of 9500 min–1.
The four radially arranged valves ensure extremely compact combustion chambers so that there is no need for the second spark plugs as used in the R models until now.
The compression ratio is 12.5:1. Super Plus with 98 RON is recommended as the fuel for optimum performance although the motorcycle can also run on Super 98 RON.
The horizontal arrangement of the camshafts introduces two special features: Each of the shafts controls an intake and outlet valve and the cams are conically ground. For a higher gas throughput, the valve plate diameter was increased from 36 to 39 millimeters (intake) and from 31 to 33 millimeters (outlet) respectively.
The intake channels were machined for optimization. The operating technology with drag lever works with shims sitting on the valves as in the K 1200 engines. The cylinder head covers are made from carbon and fitted with easy-to-replace slip pads made from PA6 hard plastic.
High-strength and lightweight forged pistonThe bore and stroke ratio is unchanged in the HP2 Boxer. The high-strength, weight-reduced forged piston and the correspondingly adapted conrod are new.
Interacting with the new intake pipe system with its a short intake air funnel, the power plant develops a top performance of 96 kW/128 bhp at 8750 min–1 and a maximum torque of over 115 Nm at 6000 min–1.
Flow through two parallel and consecutively switched oil coolersSo that the Sport Boxer operates well under all conditions from the thermal aspect, two oil coolers positioned one after the other and with a parallel flow-through are deployed.
Wind tunnel optimization of the BMW ‘kidneys’ in the front fairing ensures an effective flow through the double oil cooler.
Stainless steel exhaust system with active exhaust gas flapFor the first time the 2-in-1 exhaust system made completely from stainless steel is placed under the oil sump. This configuration guarantees optimum angles of tilt when riding. An exhaust flap in front of the double exhaust pipe silencer at the rear and actuated by an electronically controlled servomotor via cable produces a fuller torque curve.
A fully-controlled catalytic converter cuts exhaust gas emissions. Oxygen sensors in the two header tubes monitor the oxygen level and guarantee an optimum air-fuel ratio over the entire torque band.
An example of the great attention to detail that characterizes both the development and production of the BMW HP2 Sport is the exhaust pipe fixtures on the single-piece, self-supporting carbon rear. These are thermally decoupled while, at the same time, compensating for the change in length of the exhaust system during warming and cooling.
The hump also boasts sophisticated ventilation openings, used to effectively deflect the heat away from the underseat exhaust. Additional features of the exhaust system are the highly attractive design and the impressive Boxer sound that escapes from the high-volume silencer.Close-ratio six-speed gearboxIn contrast to the gearbox of the BMW R 1200 S, the first and second gear have higher ratios so that the gear increments are closer. This results in a lower drop in revs when changing up in gear. This configuration is also a typical racing feature that benefits the dynamic driving characteristics.
Straight from the racing world: Gearshift assistantA further pedigree racing detail is the standard gearshift assistant of the BMW HP2 Sport, also described as an automatic gearshift. The system allows rapid gear change without reducing the gas or using the clutch. If the gear lever is activated, the electronic engine control throttles back the ignition angle and reduces the injection.
This means the power unit is at “low load” for the gearshift so it is possible to change gear rapidly without needing the clutch. The gearshift assistant operates under normal riding conditions and, on request, for racing with an inverted switching scheme (pressure sensor as special equipment).
However, if the rider actuates the clutch, the system remains inactive. The BMW HP2 Sport therefore always leaves the decision of whether or not the gearshift assistant is deployed to the driver.
Modified frame constructionThe steel tube mid-frame comes from the BMW R 1200 S, but was adapted to the new single-piece and self-carrying carbon fiber composite rear in the area around the location points.
Telelever with Öhlins sport spring strutThe front wheel suspension is provided by the stable, approved telescopic lever construction. Its trailing link is supported by a specially tuned Öhlins sport spring strut with compensating tank, adjustable in tension and compression stroke damping as well as in the spring pre-tension.
The expanded surface around the slider clamping device in the lower fork brace allows fine adjustment of the vehicle height.
Quality components made of milled aluminumThe upper fork brace and the two adjustable high-quality stock handlebars flange-mounted in the crankshaft throw are made from fully milled, forged aluminum parts. The main brake cylinder and the clutch master cylinder with radial pump coupling fixed by quick-release clamping calipers usually found in racing are also used here.
EVO Paralever with Öhlins sport spring strutThe Paralever rear wheel suspension also originates from the BMW R 1200 S, but in the BMW HP2 Sport it has an Öhlins sporting spring strut with compensating tank adjustable in all aspects. Thanks to the longitudinal adjustment integrated in the spring strut the vehicle height can also be varied at the rear.
This means the chassis geometry of the BMW HP2 Sport can be individually optimized for different racing circuits. Every BMW HP2 Sport is supplied as standard with an exclusive toolset which can be used to make all settings on the chassis components.
Exclusive forged wheels and racing tiresThe BMW HP2 Sport runs on specially developed, weight and stability optimized, surface-milled forged wheels of size 3.5 x 17” or 6.0 x 17”.
These are considerably lighter than conventional die-cast wheels, but have comparable high stability. The handling characteristics benefit enormously from the smaller rotating masses. The sports Boxer is really easy to steer on bends and allows incredibly rapid change of direction.
The forged wheels are fitted as standard with sports tires in 120/70 ZR17 format at the front and 190/55 ZR17 at the rear. These tires from renowned manufacturers – generally used only on the racing circuit such as the Supersport championship, for example – are homologated for use on asphalt road surfaces. The engineers decided on a 55 series tire cross-section as this achieved the best results for the overall characteristics in tests.
Brembo monoblock racing brakesThe braking system of the new BMW HP2 Sport also presents itself as uncompromisingly sporty. Single-piece, radially mounted four-piston brake calipers from Brembo that hold the two 320-millimetre discs powerfully in its grip are used on the front.
The radial screw connection is effected by a new die-cast foot on the lower part of the Telelever. A double sliding piston decelerates the rear wheel. It goes without saying that the hydraulic application of the brake calipers is activated by high-quality, steel armored brake lines.
Modified, switchable BMW Motorrad ABS is optionalBMW Motorrad offers an ABS adapted to sporting events as an option. The function of the system has been optimized to prevent the rear wheel from lifting.
An additional pressure sensor in the front brake circuit provides sensitive regulation of the system and the control unit prevents the front wheel brakes from opening too early when the load on the rear wheel is greatly reduced. Nevertheless the ABS can be deactivated for racing events.
Racing ergonomicsEven at the outset of the development, the engineers focused on the seat position. Compared to the BMW R 1200 S, the rider moved closer to the handlebar resulting in a notably more upright seat position oriented towards the front wheel and behind the ‘waistline’ of the fairing.
More importantly, the remarkably slim design of the tank area favors the rider’s weight displacement (hanging off) on the racing circuit. The BMW HP2 Sport also benefits here from the experiences gained in long-distance races where it is not only a question of speed, but also of staying power. Because the rider finds a suitable, but comparatively relaxed, riding position for racing, the new BMW Sport Boxer offers genuine endurance qualities.Adjustable footrest systemThe range of high-grade racing components includes the adjustable footrest system made of milled, high-strength aluminum. An eccentric cam is used to adjust the height of the footrests and to move them forwards or backwards.
Stepped setting positions of the footrests make sure that identical adjustment is possible on both sides. At the same time, the likewise fully adjustable brake and gear lever allow optimal positioning of the operating elements.
Adjustable stock handlebar and Magura manual fittingsAlso the stock handlebar of milled forged aluminum is ideally positioned and can be adjusted by changing the offset. The Magura radial manual controls allow manual lever width setting of the brakes and clutch.
All Carbon fiber composite fairingAll the fairings of the BMW HP2 Sport are made from carbon where the single-part rear as well as the front fairing are realized as self-supporting elements. The latter has a noticeably slimmer construction than the BMW R 1200 S and houses lightweight, high-luminosity halogen twin headlamps with free-formed surface reflectors. Special details include the number plate carrier of the BMW HP2 Sport: It can be removed along with the tail lamp and indicators in a few easy steps before taking part in a race.
Refinements in the wind tunnelLike every BMW Motorrad the new BMW HP2 Sport was also given its finishing touches in the wind tunnel. Not only were components such as the windshield and new rear-view mirror optimized from an aerodynamic aspect; the engineers also paid particular attention to the airflow for cooling the engine.
So the front spoiler guides the air stream specifically towards the outlet side of the cylinder heads while the BMW ‘kidneys’ in the front fairing guarantee an effective flow of the double-oil cooler. Lastly, elaborate ventilation openings in the carbon tail ensure that the heat of the underseat exhaust system is efficiently deflected.
Sports info centre: GP dashboard from 2D systemsA real highlight for all racing enthusiasts is the production-line dashboard in the cockpit of the BMW HP2 Sport. It was developed in collaboration with the acclaimed company 2D Systems that also deploys its systems in GP racing for data recording and analysis.
The system has a large, easily readable digital display and works in different modes. It is operated by two switches on the left handlebar control.
In road mode the rider can view typical information such as revs, speed, time, kilometers, remaining distance and driving time on the display and is shown supporting information during the warm-up phase of the engine.
In race mode the screen provides data about circuit times, maximum revs, top speed or number of gearshifts, for example. The stored data can also be read out with a laptop. In addition there are eight freely programmable LEDs in the upper area of the dashboard that can be used as a rev display or external gearshift light.
Like the other functions, the displays are also freely programmable. Finally, the GP dashboard offers a large number of expansion options. A lap timer with transmission/receiving unit, GPS tracking or datalogger can be connected to a free input.
Following the BMW Motorrad motor sport designThe fairing of the new HP2 Sport is realized to a large extent in carbon-look and follows the style of the BMW Motorrad motor sport design with white lacquering on the windshield, rear, mudguard and side cover.
The engine spoiler carries the two-tone “HP2” lettering. The lattice frame and wheels are lacquered in the BMW Motorrad color of Motorsport Blue.
Based off the success of the F650GS and F650GS Dakar, BMW has revamped its dual-purpose machines with a trio
of 650 Singles that will simultaneously expand and eradicate the existing model range. The Dakar version will
have gone the way of the dodo after 2007 and the standard GS is likely to follow in the next couple years.
The popular six-fifty is still alive and well, however, inside the new X series, but as BMW aims to attract
new buyer demographics, the Xs have definitely taken a step away from their predecessors. We've already
reported on the most serious street machine of the three, the Xmoto, but well-funded off-roaders and
dual-sport riders will take a higher interest in the Xchallenge and Xcountry.
At the heart of this machine is a 652cc DOHC motor which is simply a re-worked version of the GS engine.
Utilizing a balancer shaft to negate the notorious 650 shiver, the 4-valve mill is good for a claimed 53
horsepower and 44 lb-ft of torque; that's three ponies more than the previous GS motor and with increased
response. The level of vibration rises to noticeable amounts as the revs climb into higher rpm, roughly 6000
revs, and are annoying by 8500. Regardless, the torquey motor is easy to keep under this rpm range if desired,
with the use of BMW's 5-speed tranny. Doing so requires moderately aggressive riding, but as we discovered,
it's the preferable method of transport with both machines, at least in the dirt.
In addition to the balancer shaft, other notable carryovers from the GS model are electric start, dual
ignition, electronic fuel injection, 5-speed transmission and a three-way catalytic converter.
Having the gas tank under the seat is a concerted effort to centralize mass in the X series. With 2.5 gallons
available, the X bikes have less than half the capacity of a KTM 640 and even less than the notoriously
limited Honda XR650R. However, an average of 54 mpg on the Xcountry means that you can concentrate on riding
more than stressing about your next fuel stop. BMW claims it's conceivable to expect nearly 62 mpg, but we're
plenty happy with mid-50s, especially considering that we weren't being shy about downshifting and revving the
piss out of each gear.
That means the
11.5:1 compression ratio of the oversquare powerplant is simple to get fired and runs smooth and clean no
matter what elevation or temperatures your adventure brings. A far-between, 6000-mile recommended maintenance
schedule is another welcome inheritance. The e-start is especially nice considering that the motor stalls
fairly easily for a 650 and absolutely refuses to bump start. A well-placed stab with your right thumb will
get things moving again. The left-side stainless muffler is new for the X models.
To help the motor rev faster, the airbox and exhaust were redesigned and the 280-watt alternator was trimmed
to reduce the amount of spinning mass. It's also tucked behind a magnesium cover for less weight. The whole
motor package is produced by Austrian company, Rotax, while the rest of the "German" machine is co-designed
and manufactured by Italy-based Aprilia.

The steel bridge, tubular frame utilizes the motor as a stressed member. Without a cradle, the side spars are
constructed of steel and pressed aluminum. The swingarm is a two-piece aluminum unit and the removable
subframe is also made of the lighter material. With 27.5 degrees of rake, 4.6 inches of trail and a 36.6-inch
seat height, these are the types of numbers you'd expect to see on a razor-sharp motocross chassis, but a
claimed dry weight of 318 lbs (344 wet) is more in line with our expectations for a 650 off-roader.
