Pininfarina has a long history of designing - and occasionally building - some of the most beautiful cars in the world. But these cars have always worn the badge of other car makers. But now company the has struck out on its own with an all-electric hypercar called the Battista. The 2,000bhp, £2m monster is largely irrelevant to most people and will rarely be seen. But if all goes according to plan, it will be the first in a series of sports cars wearing the Pininfarina name - and all will be powered by electricity.
