Kevin and Michelle of Organic Racing have embarked on the unique challenge of building what most people would consider a contradiction in terms: an environmentally sustainable race car. This Lotus 7 replica is built largely with salvaged or recyled parts, including a junkyard Honda S2000 VTec and an STi rear end. This husband-and-wife team is one of the few that's running the entire One Lap event with an open cockpit, through all the nasty elements. (They've got heated racing suits and rain gear, but damn). Crazier still, their homebuilt trailer, known among One Lap participants as "the coffin," will actually be used by whoever's not driving as a sleeping pod—while running on the highway. Would you dare? The Lotus gets 31 mpg highway on E85, which is great—though with emerging evidence that ethanol isn't the environmental silver bullet that it was originally touted as, a turbo-diesel swap and a vegetable oil conversion might have to be next! We'll be keeping an eye on the Lotus as One Lap unfolds, and you'll be seeing it again real soon at the GRM Green Track Car Challenge in Buttonwillow next month.
