Carbon Racing Technology: BMW M GmbH factory produces a limited-edition high-performance sports car based on the BMW M3 Sedan – Innovative use of carbon-fiber reinforced plastic minimizes weight – Weight-to-power ratio: 3.5 kilograms per horsepower.
BMW M GmbH used the M Night Event in the lead-up to the Nürburgring 24-hour race to unveil a spectacular new addition to its model range. The BMW M3 CRT (Carbon Racing Technology) embodies a concentrated blend of state-of-the-art development expertise – inspired directly by motorsport – in the areas of drive system, chassis technology and intelligent lightweight design.

2011 BMW M3 CRT.

It also represents the worldwide debut of a new production process for carbon-fiber reinforced plastic (CFRP) components in the automotive industry. This process allows CFRP to be introduced widely in the construction of the high-performance BMW M3 Sedan-based sports car created by the BMW M GmbH factory. And that helps it achieve a weight-to-power ratio of 3.5 kilograms per horsepower (7.7 lbs/hp). A V8 engine with customary M high-revving characteristics and maximum output of 331 kW/450 hp accelerates the BMW M3 CRT from 0 to 100 km/h in just 4.4 seconds. The BMW M3 CRT will be produced by the BMW M GmbH factory in a limited run of 67 units. Due to the very limited worldwide volume, the BMW M3 CRT will not be homologated for sale in the USA.

Following in the tire tracks of the BMW M3 GTS – of which 135 examples were produced – this is the second small-series, high-performance M3 off-shoot to be bred for the race track but registered for the road. The exclusive character of the Sedan is emphasized by special lightweight design components manufactured as part of an innovative production process. The hood of the BMW M3 CRT and the bucket seats for the driver and front passenger are made from a cellular carbon honeycomb, which is produced in a globally unique process pioneered for the manufacture of body components for the BMW i3 and BMW i8 models.

Innovative manufacturing process for lightweight CFRP components.
These new models – due to enter volume production in 2013 and equipped with innovative electric and BMW ActiveHybrid drive system technology – will feature a body consisting entirely of CFRP in the passenger cell area. In a new development, the production process introduced for this purpose enables the cuttings left behind in the construction of the body to be reprocessed. The basic material (made up of carbon fiber thread) can now be woven into CFRP mats of any size before being impregnated with synthetic resin and hardened in a similar way to the material used in the body of the BMW i3 and BMW i8. For the BMW M3 CRT this allows the creation of a hood made from two CFRP moldings encasing an aramid honeycomb structure. This construction imbues the hood with the strength of a conventional steel equivalent, but at roughly a quarter of its weight. The weight saving over the aluminum hood of the standard BMW M3 Sedan is around 50 percent.

The material produced through this innovative manufacturing technology is also used for the car’s bucket seats. Here, the CFRP layers are wrapped around a recycled-paper honeycomb, with a carbon layer made using conventional production technology added to visible areas. CFRP is also used to make both the rear spoiler of the BMW M3 CRT and an air-channeling element integrated into its front fascia.

This innovative manufacturing process opens up considerable potential for increased use of CFRP in series-produced cars as a means of lowering weight. The BMW Group is leading the way in this area of automotive construction, while BMW M GmbH can call on extensive racing expertise when it comes to intelligent lightweight design. The BMW M3 CRT is the latest in a fine tradition of highly exclusive high-performance sports cars optimized with the help of lightweight design. This lineage stretches back to the BMW 3.0 CSL of the 1970s and reached another high point in 2002 with the BMW M3 CSL. BMW M GmbH also broke new ground with the use of CFRP in series-produced vehicles; like the BMW M6 produced up to 2010, the current BMW M3 Coupe comes as standard with a roof made from carbon-fiber reinforced plastic.

Significant weight reduction despite generous standard equipment.
The low-weight construction of the BMW M3 CRT is enhanced by sound-proofing configured specially for the new variant and a sports exhaust system with an extremely lightweight titanium muffler. Also unique to the CRT are the two individual rear seats, which take their cues from the lateral support-enhancing contours of the front seats.

Included in the standard specification of the BMW M3 CRT are the M double-clutch transmission with Drivelogic, Navigation system Professional, BMW Individual High End audio system, a light, exterior mirror and luggage area package, an alarm system and Park Distance Control with sensors at the front and rear of the car. Despite this extremely generous selection of standard kit, its DIN unladen weight of 1,580 kg (3485 lbs) undercuts that of the standard BMW M3 Sedan by around 45 kg (100 lbs). When you take into account the equipment on board the weight saving is more like 70 kg (154 lbs). Added to which, cleverly reducing the load at the front of the car raises the proportion of the car’s weight over the rear axle to 48.4 percent, which has an extremely positive effect on agility.

High-revving V8 engine with extra power; M DCT Drivelogic.
Under the CFRP hood of the BMW M3 CRT lies a variant of the V8 engine developed exclusively for the BMW M3 with further increased displacement, output and maximum torque. The high-revving unit provides the linear power delivery you expect from an M car and a highly responsive performance profile honed by the demands of the race track. Tuned for the BMW M3 GTS, the eight-cylinder engine develops 331 kW/450 hp from its 4,360 cc displacement. Maximum output is reached at 8,300 rpm, and the driver will find peak torque of 440 Newton meters (325 lbs-ft) on tap at 3,750 rpm. Helping to give the engine its intoxicating performance is wizardry derived directly from motorsport, including a bedplate crankcase construction in a special aluminum-silicon alloy, individual throttle butterflies, a knock control system with ion current technology and a dynamically-optimized wet sump oil supply.

Transferring the engine’s power to the rear wheels is the M double clutch transmission (DCT) with Drivelogic developed for the BMW M3. The seven-speed M DCT Drivelogic unit also works according to a principle developed in motorsport, allowing an uninterrupted flow of power through gear changes to deliver extremely dynamic acceleration. Its shift characteristics have been tuned specially for the engine powering the BMW M3 CRT. Shift paddles on the steering wheel allow the driver to change gear manually with optimum ergonomics. And a Launch Control function is on hand to generate maximum acceleration off the start line.

Special chassis construction with race-bred technology.
Expertise from race competition also makes its presence felt in the chassis technology of the BMW M3 CRT. The BMW M3 Sedan’s front and rear axle construction has been enhanced by a rigid rear axle subframe and coilover suspension whose dampers are individually adjustable in their compression and rebound. The 6 piston, fixed-caliper high-performance brakes of the BMW M3 CRT boast a low-weight compound construction. The vented brake discs measure 378 x 32 millimeters at the front axle and 380 x 28 millimeters at the rear. The new M3 variant also uses Stahlflex stainless steel brake lines and special brake pads.

The specially tuned DSC (Dynamic Stability Control) system – including ABS and M Dynamic Mode (MDM) – responds to both the greater dynamic potential of the BMW M3 CRT and its optimized axle load distribution. Meanwhile, the 245/35 R 19 front tires and 265/35 R 19 rears (fitted on 19-inch M light-alloy wheels in Y-spoke design) ensure the engine’s acceleration and braking power is transferred to the road with maximum impact. The electronic engine management of the BMW M3 CRT caps its top speed at 290 km/h (180 mph).

The exclusive Frozen Polar Silver metallic exterior paint shade in combination with Melbourne Red metallic applications and special treatment for the BMW kidney grille also help to set the BMW M3 CRT apart from the standard M3. Inside, the Sedan comes with likewise exclusive door sill strips, door panels and trim strips in aluminum grain structure. Completing the distinctive ambience inside the high-performance Sedan are the Alcantara-covered M steering wheel, which has an M Drive button allowing the driver to call up his preferred set-up instantly, and special Sakhir Orange and Black bi-color covers for the front and individual rear seats.
