We did an extensive acceleration-coast down test with the vehicle dynamics group from OPEL/GM in 1995. The computer recorded time and speed change every meter. This way we gained an understanding of the force needed to drive a certain speed. One doesn’t even have to drive 200 mph to get that value. We accelerated from 35 mph to 145 mph on the A5 Frankfurt – Darmstadt.

In another thread somebody confirmed a similar hp needed by Dick Smith’s car to drive 198 mph. Albeit with a small screen instead of a hardtop.

We used the hoardtop because it was 40°F!
