The M8 uses the same engine as the BMW M5 saloon, but with even higher power and torque outputs: 616bhp and 553lb ft respectively. It's a belter that, despite being turbocharged, responds almost the instant you prod the ‘go’ pedal, with the legs to outrun a DB11 and give your passenger the willies: the coupé hits 0-62mph in just 3.2sec, while the convertible is less than a blink of an eye behind. An eight-speed automatic gearbox and four-wheel drive are standard, but you can set it to rear-wheel drive if you’re feeling bold. Performance upgrades are available, such as a delimited top speed of 189mph (the default is a limited 155mph).
