BMW 760Li

With 12 cylinders and two turbos, it’s no wonder the 760Li is BMW’s fastest-accelerating car. Eclipsing even the M6 Coupé, the new motor hits 0-60mph in a blistering 4.5 seconds.

That’s all thanks to an amazing 6.0-litre twin-turbo V12… yet is this a vehicle the world needs? We’d argue not – but ignoring that for a moment, the model is very impressive. Acceleration is monumental, as is 544bhp, but it’s the 750Nm of torque that really gives the 7 its legs.

Despite soft throttle response, the turbos quickly wake up and thrust the car forward. Even at low speeds the traction control is hyperactive – the turbos blow hard straight from the off, meaning a careful right foot is needed for smooth driving.

The car uses BMW’s first eight-speed box. In town this can feel jerky, but on open roads it’s brilliantly smooth, with fast, imperceptible shifts.

The cabin focuses on comfort, particularly in the back. Its twin seats are fully adjustable, while double glazing and Nappa leather provide a haven of luxury. Despite plenty of space, though, the car is still little different from a 730d – and BMW admits annual UK sales could number only 50.
