This ultra sleek 2023 KTM X-BOW GTX is a track-only supercar designed by Austrian manufacturer KTM, known primarily for its motorcycles. It’s an evolution of the X-BOW lineup, which began in 2008 as a lightweight, carbon-fiber-intensive sports car.
The GTX has a super strong FIA-approved carbon-fiber frame weighing only 89 kg (196 lbs), which keeps it rigid and safe. It’s paired with a steel roll cage built for racing to make it even tougher and protect in crashes. Its light build means the whole car weighs about 1,048 kg (2,310 lbs) when ready to race, making it one of the lightest in its group.

It’s powered by a turbocharged 2.5-liter Audi TFSI inline-five engine (taken from the Audi RS3), placed in the middle, pumping out around 530 horsepower in race mode. It’s hooked up to a six-speed sequential manual gearbox with a Holinger locking differential for smooth power. For suspension, it uses a double-wishbone setup with Sachs adjustable coilovers to keep handling sharp, and it’s got Brembo brakes (305 mm in front, 262 mm in back) for ensure it stops on a dime.



The cockpit is simple and all about racing, with just one Recaro composite racing seat, a Schroth safety harness, and a steering wheel you can take off that has a digital screen built in. A MoTeC data logger and side-view camera screens make it easier to use on the track, taking the place of regular mirrors. Its fully covered canopy, unlike the open-top original X-BOW, gives it a fighter-jet look but skips road-friendly stuff like air conditioning or Bluetooth. Interested?
