More power, less weight. That's what we like to hear, and Florida-based supercar-maker Mosler has answered the call with its new MT900 GTR XX. Based on the MT900 GTR, which itself is as barely legal as the Olsen twins, the XX spec packs an extra 20 horsepower and loses 150kg in dead weight.

To trim the fat, Mosler fitted a new six-speed sequential transmission weighing 10kg less than the "conventional" version, installed a titanium exhaust system that weighs 5.5kg less than the steel tubes, replaced the brakes with aluminum brake calipers and carbon-ceramic discs, reworked the carbon-fiber body panels, developed seats that weight 4kg less apiece and cut 5kg out of the air-con. The Richard Simmons weight loss program further unburdens the 620-hp 7.0L Corvette LS7 V8 to bring the sprint to 100km/h (62mph) down to three seconds flat, and 200km/h (124mph) down to 8.7 seconds. If that sounds bonkers already, consider the rumors that Mosler is working on a twin-turbo version for the future, which is looking brighter and faster by the day.
