The M6 is the energetic performance derivative for the BMW 6 Series range. Like the 6 Series, customers can choose the M6 in multiple bodystyles. These include two-door Coupe, two-door Convertible and four-door Gran Coupe. The 552bhp delivered from the M6’s 4.4-litre twin-turbo V8 petrol engine is certainly eye-catching. The M6 is a good car for those looking to buy a powerful model which can be used for comfortable everyday use.
