You've got the Ferrari, Lamborghini, Porsche, and perhaps even a Bugatti Veyron. Add to this some uber premium sedans and you're almost set. Almost. Now you think it's time to own something that's not only rare, but unique in its own right. Of course, it must have stellar performance, good build quality, and the appearance of something special. The Ultima GTR may be the answer. Built by Ultima Sports Ltd that's based out of England, its builders call it a supercar even though it's available in both kit and turnkey form. The GTR is a mid-engined two-door coupe with rear-wheel-drive, a tubular space frame chassis, and a fiberglass body.
Although some will opt to build the car themselves in kit form, the company highly recommends for a Chevrolet small-block V8 mated to either a Porsche or Getrag transaxle as the ideal engine-transmission combination. Turnkey versions are also sold with this combo. But for those who want something even more insane, the company began to offer more powerful versions just a few years ago. The GTR640 is powered by an American Speed engine and produces a solid 640hp. If that's not good enough, then buyers can go with the GTR720 with - you guessed it - 720hp.
With this latter setup, the car can supposedly go from 0 to 60 mph in 2.6 seconds and can do the quarter mile in 9.9 seconds at 143 mph. All told, it weighs just 2,183 lbs., thereby giving it a better power-to-weight ratio than some of the world's finest hypercars, including the Bugatti Veyron, Enzo Ferrari, and the Koenigsegg CCGT. And if 720hp doesn't suit you enough, the Ultima's chassis has been engineered to handle up to 1,000hp. 'Top Gear' fans will also remember the Ultima GTR720 lapping the show's test track in just 1 minute, 12.8 seconds.
