The F91 Convertible, F92 Coupe, and F93 Gran Coupe BMW M8 represent the zenith of the modern M-division lineup. Combining extreme luxury with blistering performance, the 4.4-litre TwinPower turbo S63B44 engine produces between 600bhp and 625bhp. Transmitting this power through an 8-speed M Steptronic transmission and the highly versatile M xDrive all-wheel-drive system, the M8 is a true supercar killer. JXL Performance provides the elite aftermarket hardware required to push this flagship platform even further.
