No, the two have the same engine but the M6 weights about 500kg lighter. But that only matters in a straight line. In a corner, the M5 is simply too long to have a good turning feel.
Ahh yes the BMW M6 will win this one mate!
**These are all current model year '08-'09**
The BMW M6 has a hand built BMW Motorsport 5.0 Liter V10 engine developing some 500-507 BHP - top...
That's a tough one. The 528i weighs less, but has an engine with less torque and horsepower. Honestly none of those cars are exactly "fast." How about this, a 1997 540i has the same engine as a 1997...
