This process allows CFRP to be introduced widely in the construction of the high-performance BMW M3 Saloon-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. 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. Following in the tyre 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 Saloon is emphasised by bespoke lightweight design components manufactured as part of an innovative production process. The bonnet 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.
Under the CFRP bonnet 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 metres on tap at 3,750 rpm. Helping to give the engine its intoxicating performance is wizardry derived directly from motor sport, including a bedplate crankcase construction in a special aluminium-silicon alloy, individual throttle butterflies, a knock control system with ion current technology and a dynamically-optimised wet sump oil supply.
Transferring the engine’s power to the rear wheels is the M doubleclutch transmission with Drivelogic developed for the BMW M3. The seven-speed M DCT Drivelogic unit also works according to a principle developed in motor sport, 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.
Expertise from race competition also makes its presence felt in the chassis technology of the BMW M3 CRT. The BMW M3 Saloon’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 sixpiston, fixed-calliper high-performance brakes of the BMW M3 CRT boast a low-weight compound construction. The vented brake discs measure 378 x 32 millimetres at the front axle and 380 x 28 millimetres at the rear. The new M3 variant also uses Stahlflex brake lines and model-specific comfort 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 optimised axle load distribution. Meanwhile, the 245/35 R 19 front tyres 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.
