Ahead of the arrival of the performance-orientated BMW M8, German tuning house AC Schnitzer has shown what it can do with the G15 8-series Coupe. The kit adds aggression to the grand tourer thanks to a range of body and suspension modifications alongside enhanced performance.

Presented at the Essen Motor Show, the model shows customers what to expect from a production version of the 8-series Coupe by AC Schnitzer. For the range-topping M850i xDrive, the tuner will squeeze 450kW from the twin-turbo V8, up around 60kW from the standard 390kW figure – torque is also up around 95Nm to a significant 848Nm. It isn’t just the M850i that the company will tune, though, as it will also take the 840d xDrive from 235kW and 680Nm to around 283 and 780Nm.

Every AC Schnitzer-fettled 8-series model will also get a new exhaust system for a racier sound, with four large diameter pipes finished in carbonfibre making an appearance. Modifications don’t stop there, however, with the suspension getting some attention too. AC Schnitzer says it’s working to create a perfectly tuned suspension setup, lowering the car (by around 20-25mm at the front and 10-15mm at the rear), retaining the comfortable driving experience while also optimising its driving dynamics.

A staggered wheel setup featuring larger, lighter wheels than the ones fitted at the factory will also be included alongside numerous lightweight carbonfibre components. Splitters, canards, bonnet vents and a whole host of other parts finished in the lightweight material will add to the aggression of the kit.

AC Schnitzer claims the carbon ‘racing’ rear wing and rear diffuser will improved downforce and aerodynamic balance, with the help of various other aerodynamic components on the exterior of the car. Side skirts will also complete the look, also finished in carbonfibre, of course. Continuing the theme on the inside, AC Schnitzer adds tweaks including aluminium shifting paddles and pedal set with a matching footrest.

Although the model shown will likely be very close to the product customers will receive, the company claims that some areas of the car are yet to be finalised.
