Who said muscle cars can't be green? The video above is all about the 2008 Indy 500 pace car, an E85-fueled Corvette Z06. Chevy does not make an E85 Corvette but this concept may hint at future plans from Chevy's gas friendly to gas free strategy. The video includes the pace car driver, two-time Indy 500 winner, Emerson Fittipaldi, joking it will be great to look in the mirror and see all those Indy cars behind him. The Z06 is capable of changing colors from green, blue, gold and yellow and you can check it out in the 2008 Indy 500 which airs Sunday, May 25, 2008.
