BMW’S M division returns to the 6-Series, rekindling memories of the old M635 CSi of the late 1980s. The M6 Coupe and Convertible use the same 5.0-litre V10 engine as used in the M5 saloon, which is said to be capable of 205mph if completely derestricted – luckily UK cars come restricted to 155mph. The M6 has many bespoke parts over a standard 6-Series and BMW claims it deserves comparison with illustrious models from Ferrari and Porsche.

It’s not quite that good (although it’s certainly expensive) and is perhaps a little intimidating on UK roads with almost too much power. However the M6 will remain an exclusive and dramatic high-performance car for uncompromising customers.
