Set-up button for direct access to the configuration of all powertrain and chassis systems
The BMW M8 Competition models allow the driver to choose various settings for the engine, suspension, steering and braking, independently of one another, using the Set-up button on the centre console. Through the M xDrive all-wheel-drive system, the driver is also able to adjust how power is distributed between the front and rear wheels.
The engine characteristics can be adjusted by means of the EFFICIENT, SPORT and SPORT PLUS settings, while the COMFORT, SPORT and SPORT PLUS chassis options give access to the three profiles for the electronically controlled dampers. The driver can also choose between COMFORT and SPORT for both the M-specific electromechanical steering and the new braking system. When DSC is deactivated, the 4WD, 4WD SPORT and 2WD (pure rear-wheel drive) settings for the M xDrive all-wheel-drive system also come into play.
Two individually composed variants of this M set-up can be stored permanently with the driver’s preferred settings for the engine sound, gearshift characteristics of the eight-speed M Steptronic transmission, driving stability control and Auto Start-Stop function. The overall vehicle configuration can then be called up at any time by pressing one of the two M buttons on the steering wheel.
Adaptive suspension with electronically controlled dampers
Both BMW Competition models feature standalone configuration and tuning of selected chassis components to deliver agile handling. The vehicle set-up has been carefully adjusted to the engine’s higher output, generating an exclusive racing-car feel. Both cars utilise M-specific Adaptive suspension that has electronically controlled dampers. The basic damper set-up, therefore, can be varied at the touch of a button.
The Competition models’ bespoke modifications translate first and foremost into superior steering precision and cornering dynamics. It starts with the extra-stiff engine mounting to ensure greater precision on turn-in while increased camber at the front axle enhances their ability to absorb lateral forces through high-speed corners.
M Servotronic steering with variable ratio
Another factor in delivering the driving experience for which M models have become renowned is M Servotronic steering. The electromechanical system combines speed-sensitive power assistance and a variable steering ratio, enabling exactly the right amount of steering torque for every situation. The result is accurate turn-in and sensitive communication of the steering wheel’s movements when powering through bends and effortless manoeuvring and parking at low speeds.
Steering response can also be varied by pushing a button to select one of two settings. COMFORT mode combines cornering accuracy with well-resolved steering feel, while also providing the driver with plenty of feedback. In SPORT mode the steering is even more communicative and noticeably greater force is required to turn the wheel in more dynamic driving situations.
Premiere for integrated braking system with M-specific configurability.
The M compound brakes are standard for the new BMW M8 Competition models. The drilled, inner-vented discs on the front wheels are 395 millimetres in diameter and feature six-piston fixed callipers. The rear wheels work with single-piston floating callipers and 380-millimetre discs. The optional M carbon-ceramic brakes – with 400-millimetre discs at the front axle and 380-millimetre discs at the rear – provide even greater stopping power, resistance to fade and thermal stability, not to mention an extraordinary ability to fend off wear.
Both brake variants are fitted in conjunction with an M-specific version of an integrated braking system. Thanks to this cutting-edge technology, the brake activation, brake booster and braking control functions are brought together within a compact module. The integrated system reduces weight by around two kilograms and employs a vacuum-free brake booster to enhance the car’s overall efficiency.
The version of the new braking system developed for BMW M models also offers two-pedal feel settings. COMFORT and SPORT modes alter the amount of pressure on the brake pedal required to slow the car. The driver can, therefore, choose between more comfort-oriented and particularly direct, instantaneous response when braking.
