BMW'S fastest ever soft-top, the M6 Convertible, will go on sale in September.
Powered by the award-winning 5-litre V10 engine, using technology derived from Formula One, the new-comer combines all the performance of the M6 Coupe but with the added luxury of open-air motoring.
The 4,999cc engine develops 507bhp with 0 to 60 coming in 4.8 seconds and a top speed of 155mph. Combined fuel consumption is 18.6mpg and the price will be announced nearer the launch date.
