The true measure of making a quality race car isn't exactly measured by the amount power and speed that goes on in the car - though that's a pretty good thing to have too. No, quality is measured by developing technologies in a race car that could find its way into production cars, sort of like killing two birds with one stone.

And in today's world, no other aspect of the auto industry is as important as making cars as fuel-efficient as possible. For Chevrolet->ke199, the work is as painstaking as it is laborious. Hours are spent - not to mention the vast amount of resources - trying to develop ways to make race cars like the Corvette C6.R greener while maintaining the necessary speed and reliability to stay competitive. Whereas a lot of people are more interested in how much horsepower or how fast a race car goes from 0-60, this video - part 4 of the Corvette Racing new mini-series - gives us a glimpse of just how important eco-friendly fuel-efficiency has become, both for cars that compete on track and those that run off it.
