According to car magazine talking about the m6....'BMW engineers claim it drives very differently from the m5:more hard edged,more alert and delivering the kind of searing in-gear accleration that promises to leave the M5 trailing.Make no mistake ,the m6 promises the kind of driving experience that could break ferrari and Porsche's grip on grin-inducing driver engagement and white-knuckle driving dynamics.'
they went on to say how it is lighter and has a lower centre of gravity.
Round 1 to the M6 then,however they also indicated a price of c. £85,000 for the M6.......so round 2 to the M5 then.
As a future M6 owner I will be very very annoyed if it were c.£23000 more than the m5 ,pro rata it should be the same price level as the 645 is to the 545 surely ?
