Saw one of these today at COTA. It was on a trailer, on its way across the country to its new owner, so I didn't get to see it in action, but it's a cool toy, for sure.
2200 lbs, 300 hp, 340 tq. The engine's in the back, and it's a 2 liter GM ecotec w/ a turbo. Inside, it's a single seat dead center, and there's lots of room on each side in the cabin. The lady that was pulling it said there's an option for a (very small) 2nd seat to the left of the driver. Over on the right is the fire bottle and the dash.
69500 ready to race. I kinda want one.
