Richard‘s or mine CoC (type approval) must be wrong. We have the same car with Ford Motor 210 kW at 6000 RPM, but maximum speed is 240 otherwise 250 km/h.
I think, we agree at speeds above 200 km/h the drag resistance will restrict the top speed. It is easy to calculate, the air drag will increase with the power of 2, therefor the power with the factor of 3..
If mine CoC would be correct, we need 210kW for 250 km/h, so Richard‘s would need only 186 kW for 240 km/h.
I think, only MMC canhelp?
