The F40 is surprising fast. One individual who owns an F40 and CGT posted elsewhere that from a rolling start both cars were very close in acceleration and depending on what speed the acceleration began each one would top the other.

Considering that the F40 has 480hp it is a considerable achievement. That said, a year or two ago a magazine compared the F40 with the 430 and determined that the 430 was faster around a track. The F40 has no safety stability devices. That impeded any effort for the F40 to make better times around a track.
