The BMW i8 might just be the most ambitious car that the German company has ever produced.
Using a combination of a tiny petrol engine from the Mini hatchback, high-voltage batteries like the one in your laptop, and a powerful electric motor, it's a plug-in hybrid that's designed to be as exciting to drive as it is kind to the environment.
Under the i8's sleek skin lies a carbonfibre structure that helps cut weight and improve stiffness, to the benefit of handling and safety. Meanwhile, the unusual powertrain gives it impressive punch and the ability to cruise silently on all-electric power.
It isn’t cheap, but only the likes of the Porsche 918 Spider and McLaren P1 offer similar technology and design, and they cost close to a million pounds each. Consider it, then, a more efficient alternative to the likes of the Porsche 911 and Audi R8.
Right now it's available only as a coupe, although an open-top 'Spider' version has been shown in concept form.
