It took a bit of poking and prodding, but we managed to round up four "green" track cars for the Grassroots Motorsports Ultimate Track Car Challenge on Sunday. We have two Jetta TDIsā€”the Chili Pepper Racing TDI and the Kerma TDI. We'll also have the AC Propulsion eBox, which currently holds the 1/8th mile record with the National Electric Drag Racing Association for a street conversion. And finally, we have the Organic Racing Lotus 7 replica (an E85-powered WCM Ultralite S2K). These four will compete to see who's the fastest, and who's the greenest. Stay tuned for full coverage of Sunday's event at Buttonwillow.
