The current M5 has a maximum power of 507 hp, and it’s already a rocket ship; so, the 2009 M5 will be something insane, beyond our imagination!
Until very recently, the German car makers was something of a purist concerning petrol engines, preferring naturally aspirated over forced induction. But the current twin-turbo straight-six petrol in the 335i and 535i proves BMW can do ’charging as least as well as anyone else. Usually better. And a turbocharger or two would do wonders for the M5’s low-down torque, which we’ve found to be a little lacking in the past.
Spy photographers report that the 2009 M5 sound incredible aggressive (imagine that!) and that it may have also been using a DSG transmission in place of the current SMG unit.
