The BMW 8 Series coupe was developed in parallel to the BMW M8 GTE race car, which has already proven its potential in the 2018 FIA World Endurance Championship long-distance races and in the 2018 IMSA WeatherTech SportsCar Championship.
The launch of the M850i also marks the debut of the new BMW TwinPower Turbo V8 engine which will launch the M850i xDrive from 0-100 km/h in just 3.7 seconds. The latest generation of the 4.4-liter 8-cylinder engine has been radically revised. Some of the numerous improvements include two twin-scroll turbochargers with charge air cooling located within the V-shaped space between the cylinder banks, High Precision Injection, VALVETRONIC fully variable valve control and Double-VANOS variable camshaft timing all form part of the M Performance TwinPower Turbo technology. The extensive overhaul has given a substantial boost to maximum power, torque and efficiency.
The new V8 engine also serves up an enthralling soundtrack, which is enhanced by the standard flap-controlled sports exhaust system. It can also be toned down for more relaxed cruising. The Driving Experience Control switch can be used to activate both extremely sporty and distinctly comfort-oriented powertrain settings. In the SPORT and SPORT+ modes, accelerator response as well as the V8 engine’s power delivery and acoustics, which take on an even more distinctive note in SPORT+, are configured for an exhilarating driving experience.
The Steptronic Sport transmission’s controller is able to adapt the gear shifts to the driving situation by use of intelligent networking with the standard Navigation system, enabling it to take the planned route into account. Navigation data is used to downshift early, for example, when approaching an intersection in order to use engine braking to slow the car down. The intelligent controller is able to avoid unnecessary gear shifts between two corners that follow in quick succession, making it possible to drive through at a quicker speed.
Intelligent networking increases the efficiency of the drive system by allowing Auto Start Stop operation to adapt to suit the specific situation based on data supplied by the navigation system as well as by the cameras and radar sensors of the optional driver assistance systems. This way, inefficient engine shutdown, for example when stopping briefly at junctions with yield signs, can be prevented. The movement of vehicles ahead is registered in order to determine the ideal moment for stopping and starting the engine.
The BMW xDrive intelligent all-wheel-drive system has been improved for more efficient operation. With its rapid, precise and fully variable distribution of drive torque between the front and rear wheels, it maximizes traction and handling stability not just when driving in adverse road conditions, but in performance driving situations as well. Power is split according to demands at all times using an electronically controlled multi-plate clutch that is networked with the powertrain and chassis systems.
The suspension technology developed for the 8 Series coupe came from the racing know-how of BMW M GmbH and resulted in detailed modifications and enhancements to the overall suspension set-up. Special wheel hubs and wishbones allow camber values on both axles to be raised as far as possible. This significantly increases the car’s ability to put down power through high-speed corners.
Standard on the all-new BMW 8 Series Coupé is Adaptive M suspension with electronically controlled dampers. The extremely stiff suspension springs reduce roll tendency and allow the dampers to stabilize the wheels as much as possible, avoiding traction losses caused by bumps and ruts in the road surface.
The standard Integral Active Steering also reduces the car’s turning circle when maneuvering, increases agility at moderate speeds and optimizes stability when changing lanes and cornering at high speeds. The system combines the electromechanical steering of the front wheels (including Servotronic function for speed-sensitive power assistance) and the variable steering ratio in the rear axle steering.
The braking system has been enhanced for better brake feel in the 8 series with four-piston, fixed-calliper brakes at the front and single-piston, floating-calliper brakes at the rear. The integration of the braking system and DSC stability control provides precise braking response, braking control and brake boosting. Inner-vented brake discs and 8 series specific brake pads are used front and rear. Directional cooling air ducts help to reduce temperatures.
The 20-inch M light-alloy wheels are standard and come in the exclusive color Frozen Cerium Grey metallic with a high-gloss polished finish on the face. They are fitted with 245/35R 20 tires at the front and 275/30R 20 tires at the rear. The high-performance tires were developed by the manufacturer specifically for the all-new 8 Series Coupé.
Pricing of the M850i xDrive will be announced closer to the on-sale date in the Fall of 2018.
