Ultima Evolution Coupe

It's one of the fastest cars you can buy — but you won't be driving one of the lot anytime soon. That's because the Ultima Evolution Coupe is a kit car. Based on the legendary Ultima GTR, it features the same Le Mans Group C-inspired body shape, but underneath is powered by a LS Chevrolet V8 engine tuned to your liking, and thus producing anywhere from 350 to 1,020 hp. That top end number is good for a pants-soiling 0-60 time of 2.3 seconds and a top speed of 240 mph. There are other notable features, like a refined chassis, new headlight units, and even an optional backup camera, but with raw performance that insane, they don't even matter.
