Geneva Motor Show: BMW M6 and M Performance diesels

BMW has made the stunning new M6 official at the Geneva Motor Show. That's the supercar-chasing coupé with the supercar-chasing price: it's going to cost £100,000.

Available as a coupé and a drop top, the M6 is powered by a 552bhp 4.4-litre twin-turbo V8 engine that endows the car with a 4.2-second 0-62mph time and a limited 155mph top speed. (The convertible is a tenth slower.)
