Cars today are constantly being improved in all areas. Look at how hard an R8 can be pushed, for 24 Hours.

Likewise look how Audi technology has improved MPG and engine efficiency. Surely this has far more relevance to a street car than upgading an engine from 800BHP to 1000BHP?

As for saying road cars are not artificially regulated, what about emissions, crash/saftey legislation etc.

Modern racing has improved all of these areas, and the alternative fuels being developed for Le Mans, have more relevance to the future of road cars than possibly any other development.

In the mid 80s competition cars, whether it was turbo F1, IMSA GTP/Group C, Group B rally reached a limit were they were too fast too race.

Since then we have had ever tighter regs to keep the pace of cars stable, but at the same time we have seen more development in areas such as transmissions, braking, aerodynamics, engines, electronecs than ever before!
