The Turbo S E-Hybrid is quicker than a scalded cat on a hot tin roof. With its 4.0-litre V8 and powerful electric motor, you have up to 671bhp to play with – yes, that's correct, 671bhp in total – and that means 0-62mph in 3.8sec. Wham. And it boasts some environmental credentials, with an electric-only range up to 25 miles officially and over 70mpg – you're unlikely to get either figure in the real world, though, but you could potentially reduce your company car tax bill.
