rpet you already dream about owning an M3, so don't even think about an M5
500hp is almost sure. 4.5 secs 0-100km/u
New M5 will have 3 gearboxes available
SMG 3 (with shifting with padles on the steering wheel)
Manual 6 speed
Full automatic (orientated on the American market
These are not facts yet, but rumors.
