The KTM X-Bow GT4 almost looks like a prototype, but it complies with the FIA GT4 technical regulation. Equipped with a fully enclosed cell (unlike the road versions), it weighs just 975kg. The engine is a 2-litre turbocharged in-line 4-cylinder that develops around 320hp. The gearbox is 6-speed sequential. The X-Bow GT4 is mainly used in the German VLN championship, but can also be seen at the Nurburgring 24 Hours.
