The car is said to be a product of kit-maker Vaydor, though we can't verify that. We can say that the brakes look powerful, and that purple ground-effect lighting isn't really impressive.
Leigh also grabbed a few environmental shots from the set; enough to say that carnage should be laid on pretty thick by the time the final edit has been cut. We'd expect nothing less.
