The top speed of a M5 is at 155 mph electronically limited. The car will go faster, but the engine computer cuts off the fuel after 155.
the new BMW m5 goes up to a 205mph which is brillinant and 255 brake horse power
Depends. A 135i, 5 series, 6 series, 7 series, M series, X5M or a X6M are fast but anything else are not as fast.
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.
my dads 650 did 155
