  • Another factor in delivering the driving experience for which M models have become renowned is M Servotronic steering. The electromechanical system in the new BMW M8 Coupe, new BMW M8 Convertible and Competition models combines speed-sensitive power assistance and a variable steering ratio, enabling exactly the right amount of steering torque for every situation. The result is wonderfully accurate turn-in and sensitive communication of the steering wheel's movements when powering through bends and effortless manoeuvring and parking at low speeds.
    The variable ratio adjusts to changes in steering angle and helps to give the car superb straight-line poise, sharp turn-in response and excellent directional accuracy through corners. When the wheels are already sharply turned, the steering rack teeth are positioned more closely together, so smaller steering inputs are required. As a result, the car feels particularly nimble on winding roads and can also be manoeuvred into and out of parking spaces with far less steering effort.
    Steering response can also be varied by pushing a button to select one of two settings. COMFORT mode combines excellent 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 as the system maximises precision in dynamic handling situations.The new BMW M8 models are also equipped as standard with M-specific Adaptive suspension including electronically controlled dampers. The damping forces for each individual wheel are adjusted smoothly as a function of the changing driving situation using electromagnetic valves. To do this, the damping control takes into account the data on body movement, road surface conditions and steering movements relayed by sensors to generate the ideal damping forces for the situation in just a few milliseconds. This makes it possible to enjoy both excellent everyday comfort and extremely direct contact with the road, with low wheel and body movements.
    The high-revving V8 engine in the new BMW M8 Coupe, new BMW M8 Convertible and two Competition models is more powerful than ever, fuelled by state-of-the-art technology and the performance platform on which M models have built their reputation. The 4.4-litre unit with the latest M TwinPower Turbo technology presents a compelling blend of razor-sharp responses to every movement of the accelerator, a feverish appetite for revs and sustained power delivery across an extraordinarily wide rev band. A pair of turbochargers - positioned in the "V" between the cylinder banks and boasting optimised efficiency - and indirect charge air cooling help the engine to deliver outstanding performance. The latest update of High Precision Injection direct injection technology works with maximum pressure of 350 bar, ensuring ultra-fine fuel atomisation, to enhance both the engine's power delivery and its efficiency.
    Another technological highlight is the cross-bank exhaust manifolds. These smooth the transmission of the energy from the exhaust gas flows to the turbine wheels of the two turbochargers, ensuring instantaneous response and the best possible gas-exchange cycle. The engine serves up peak torque of 750 Nm (553 lb-ft) between 1,800 and 5,600 rpm in the new BMW M8 Coupe and new BMW M8 Convertible - and goes on to deliver maximum output of 441 kW/600 hp at 6,000 rpm, en route to the 7,200 rpm cut-off.
    The specially tuned responses of the engine powering the BMW M8 Competition Coupe and BMW M8 Competition Convertible hands customers an even more intense performance-car experience. The power unit sustains peak torque up to 5,800 rpm and develops maximum output of 460 kW/625 hp at 6,000 rpm, its race-derived, high-revving instincts taking an even more prominent lead. The V8 developed for the Competition models teams up with a special engine mounting for a more rigid connection with the vehicle structure. This results in even more direct engine response and immediate transmission of power to the drivetrain. The stiffer engine mounting also has a positive effect on the immediacy of turn-in and the transmission of engine noise into the cabin.The sophisticated cooling system deployed in the new BMW M8 Coupe, new BMW M8 Convertible and Competition models has been adapted precisely to the engine's elevated performance, construction and technological details. The central cooling module, for example, is flanked by two high-temperature water circuits. Indirect intercoolers are integrated into the low-temperature cooling circuit, while the high-temperature cooling circuit supplies the engine blocks and two turbochargers with coolant. An additional electric water pump ensures the cooling of the turbos is extended for a time after the engine has been switched off. And the system also features an additional engine oil cooler and separate transmission oil cooler.
