High-tech hybrid cars are now competing directly with 100% gasoline powered cars in 24-hour endurance races. The latest is the Gumpert Apollo Supercar which will race the 24-hour Nurburgring this year from 22 to 25 May.
Wired has a great story at http://blog.wired.com/cars/2008/05/800-horsepower.html
A hybrid Toyota Supra won the Tokachi 24-hour race last year by 19 laps, well ahead of any other cars in the field. The Tokachi race is less well known than the Nurburgring so this race may change the face of the auto industry.
I remember the year that the Chrysler turbine car nearly won the Indy 500, but broke down two or three laps from the finish line due to a broken bearing in the gear shift box. But it was one of a kind from a third rate auto company and hybrids are already here to stay. What this could do is convince the bozos in Detroit that any and all vehicles can and should be hybrids. And it could convince the American auto buying public that hybrids can save fuel and provide performance at the same time.
