BMW Concept M5
BMW’s new Concept M5, which makes its public debut at Auto Shanghai 2011, features a newly developed V8 with M twin-turbo technology. Compared to the fourth-generation M5 power unit, the newly developed engine has a significantly increased output level, while at the same time lowering previous fuel consumption and emission levels by at least 25%.
The M5 Concept engine is coupled with a seven-speed M double-clutch transmission with Drivelogic and M-specific suspension and steering. The double-clutch gearbox, which was specifically tuned to the new V8 engine’s performance characteristics, offers extremely fast gear shifting, precise gear selection and a high degree of effectiveness that further optimizes the vehicle’s efficiency. The combination of the new engine with M Drivelogic is supplemented by an Auto Start Stop function.
The BMW Concept M5 features new rear differential technology also developed by BMW M GmbH. The Active M Differential maximizes traction in cornering by using targeted variation of locking torque between the right and left drive wheels. Active control of the multi-plate lock inside the rear differential is highly accurate and fast. This ensures that wheel spin is prevented even on slippery road surfaces and in the event of differing friction coefficients between the right and left wheels, in narrow bends or during sudden lane changes.
