BMW M3 CRT (carbon and Racing Technology) is a concentration of state-of-the-art development experience - directly inspired by motor sport - the areas of the operating system and platform technologies and intelligent lightweight construction. It 'also the world premiere of the new production of carbon fiber reinforced plastic (CFRP) components for the automotive industry. This process allows the introduction of CFRP construction of extended high-performance BMW M3 Sedan-based sports car created by BMW M GmbH factory. And that allows you to reach power to weight ratio of 3.5 pounds per horsepower. V8 engine in the usual M-step characteristics at higher rpm and maximum power of 331 kW/450 hp accelerates the CRT for the BMW M3 0-100 km / h in just 4.4 seconds.
BMW M3 CRT will be produced by BMW M GmbH factory as a limited edition of 67 units. The tire tracks of the BMW M3 GTS - including 135 copies were produced - this is the second series of small, high-performance M3 off-shoot to be high for the track, but has recorded for the road. The exclusive character is underlined by the Saloon as lightweight components made in the context of an innovative production processes. The hood of the BMW M3 and CRT bucket seats for driver and front passenger are made of a honeycomb cell carbon produced in a process unique in the world pioneer in the manufacture of body parts for BMW and BMW i3 i8 models

The hood of the BMW M3 and CRT bucket seats for driver and front passenger are made of a honeycomb cell carbon produced in a process unique in the world pioneer in the manufacture of body parts for BMW and BMW i3 i8 models
Innovative manufacturing processes for lightweight CFRP components.
These new models - due to enter volume production in 2013 and equipped with electricity and an innovative BMW ActiveHybrid technology operating system - a characteristic of the body made entirely of carbon fiber in the cell of the passenger. In a new development, the production process for this purpose allows the cuts left frame a new trial. Base material (composed of carbon fiber thread) can now be CFRP woven rugs of all sizes, before the synthetic resin impregnated and cured in the same material used in the body of the BMW and BMW I3 I8. BMW M3, the CRT, this may create a carbon fiber hood that holds two moldings structure aramid honeycomb. This structure gives strength of conventional steel hood with a similar, but about a quarter of its weight. Weight saving compared to standard aluminum hood for the BMW M3 sedan is about 50 percent.
The material produced by this innovative manufacturing technology is also used for car bucket seats. Here are the CFRP layers wrapped around a honeycomb of recycled paper, with a carbon layer made using conventional manufacturing technology added to the visible areas. CFRP is also used to make the two rear spoiler for the BMW M3 CRT and an air channeling integrated into the front apron.
This innovative manufacturing process is a potential for greater use of CFRP in series produced cars as a way to reduce weight. The BMW Group is a leader in this field of automobile, while the BMW M GmbH can draw on the experience of running everything in terms of its intelligent lightweight design. The BMW M3 CRT is the latest in a fine tradition of very exclusive sports cars with high performance optimized lightweight. This lineage goes back to the BMW 3.0 CSL in the 1970s and reached a new record in 2002 with the BMW M3 CSL. BMW M GmbH has pioneered the use of carbon fiber in mass-produced vehicles like the BMW M6 produced until 2010, the current BMW M3 Coupe comes standard with a plastic roof of carbon fiber reinforced.
Weight loss despite the generous standard equipment.
Lightweight design for the BMW M3 will increase soundproofing of a series CRT, and in particular, a new variant of the sports exhaust system with a very light weight titanium muffler. Also unique in the CRT has two individual rear seats, which have received tips on improving the forms side of the front seats.
Included in the standard specification of the CRT are the BMW M3 with M double-clutch Drivelogic, Professional navigation system, BMW Individual high-end sound system, a light, outside mirrors and the cargo area of ??the package, an alarm system and Park Distance Control sensors in the front and rear of the car. Despite this generous selection of standard game, the curb weight of 1,580 kg DIN is the standard BMW M3 Sedan 45 kg. When considering the team in the weight saving is more like 70 kg. In addition, intelligently reduce the load on the front of the car increases the proportion of car weight on the rear axle to 48.4 percent, which has a very positive effect on agility.
High engine V8 engine with more power; M DCT Drivelogic.
CFRP Under the hood of the BMW M3 CRT is a variant of the V8 engine developed exclusively for BMW M3 increased further displacement, output and maximum torque. The unit provides high-speed linear power delivery that you expect from an M car and very responsive performance profile sharpened by the requirements of the course. Tuned BMW M3 GTS for the eight-cylinder engine develops 331 kW/450 hp from its displacement of 4360 cc. The maximum power is reached at 8300 rpm, and the driver is the maximum torque of 440 Newton-meters on tap at 3750 rpm. Contributes to the engine, the results are intoxicating magic comes directly from motorsports, including construction of housing built special aluminum-silicon alloy, butterflies individual gases, a knock control system with current technology ion a dynamic and optimized supply wet sump.
The transfer of power from the engine to the rear wheels, the M double-clutch transmission with Drivelogic developed for the BMW M3. The seven-speed M DCT Drivelogic unit also works on a principle developed in motorsport, providing an uninterrupted flow of power through the gears to offer an extremely dynamic acceleration. Switching characteristics have been set specifically for the engine powering the BMW M3 CRT. Shift paddles on the steering wheel allow the driver to shift gears manually with optimal ergonomics. Launch Control function and is ready to generate maximum acceleration of the start line.
The construction of special chassis with race-bred technology.
Experience racing competition also makes its presence felt in the chassis technology of the BMW M3 CRT. The construction of the sedan BMW M3 from the front and rear axle has been strengthened with a cot and a solid rear axle suspension shocks are threaded individual compression and rebound in. The fixed six-piston brakes in the high performance BMW M3 CRT benefit from a lightweight composite construction. The vented disc brakes measuring 378 x 32 mm front axle and 380 x 28 mm at the rear. The new M3 variant also uses the brake lines and pads brake specific Stahlflex model for comfort.
Specifically tuned to the (Dynamic Stability Control), DSC - ABS and M Dynamic Mode (MDM) - responsible for both the dynamic potential of the BMW M3, CRT and optimized axle load distribution. At the same time, tires 245/35 R 19 front and 265/35 R 19, to increase (installed 19-inch M light-alloy wheels Y-spoke) to ensure the acceleration of the engine and braking power is transferred to the road of great impact. Electronic engine management system is the BMW M3 CRT caps the top speed is 290 km / h.
