Not that impressive  :p |
well, we can definately tell if we know the final gear ratio/tire size (wich is findable) since we know the RPM, and hes in top gear looked about 7400-7500 rpm adjusting from the view of the passenger |
Code:
Tire Size [inches]: Diameter - 26.8"
Transmission Gear Ratio: 1: 0.833
Rear Axle Gear Ratio: 1:3.62
Maximum Engine Speed (RPM): 7400
Top Speed (mph): 195.7mp
Assuming the revs are accurate - thats 5% over reading - sort of nullifies the magazine artcicle about how inaccurate BMW speedos are.
