The fastest production car Lamborghini has ever built. A 6.5-litre V12 engine lies at the heart of the LP640, where LP stands for ‘longitudinale posteriore’, which refers to the V12 unit mounted lengthways behind the cockpit.

With deeper and wider cylinder bores than the previous 6.2-litre V12, the new 6.5 ups power to an imperious 631bhp at 8,000 good-for-the-soul revs per minute.

Coupled to a new six-speed gearbox, which can also be ordered with Lambo’s e-gear sequential paddle shift, the LP640 howls from 0-62mph in 3.4 seconds - 0.4 seconds quicker than the 6.2-litre model.

And it’s helped on its way by an electronic launch-control device called, rather brilliantly, Thrust.

Lambo has yet to announce a top speed, but word is that the LP640 will top 210mph, while low-speed driving is improved with variable valve timing and an aircraft-style drive-by-wire throttle.

For the show-offs, a glass engine cover can be ordered.
