After an absence of 16 years, the M6 made a comeback in 2005 in the form of the E63/64 (the model codes for the coupé and convertible respectively), both of which use a shortened version of the E60 M5 chassis.
It used the same engine, too, which was no bad thing considering the five-litre V10 churns out a mammoth 500bhp and 384 lb.ft. of torque in P500 specification (a P400 with 394bhp was available), power enough to propel the M6 to an artificially limited top speed of 155mph after passing 62mph in 4.6 seconds – and if that doesn’t impress you, the V-Max could be raised to 190mph if your pockets were deep enough to tick the option for the M-Driver’s package.
Part of the M6’s performance is due to its construction, where weight-saving measures include an aluminium bonnet and carbon-reinforced plastic for the front wings and boot lid.
Production for the high-performance version of the 6 Series ended after five years; just 9,087 coupés and 5,065 convertibles were built, making it as rare as it is quick.
