If you read the article, it says that their European spec Countach probably did not have 450 hp, and they calculated that it had about 370 hp. They say in the article that the Euro spec did 12.8s in 1/4 mile, and the U.S. spec was a "tick slower," although 13.3s is not really a "tick slower." It must have had even less hp.

It seems to be very common for Countaches not to be running at their full potential. Does anyone know why there are so many QV's that are running with less than 400 hp? Is it just the build quality?
