KTM, the motorcycle company, has made the Xbow track car for years, and now they’re breaking out the big guns with the Xbow GTX, a GT2-class race car that will go up against the likes of Porsche and Audi. While that’s ambitious, the GTX has the guts for it. Power comes from an Audi-sourced five-cylinder engine from the RS3 super sports sedan. But instead of the RS3’s 394 horsepower, the GTX’s gets dialed up to an even 600, combined with 2,200-lb weight. The carbon fiber body and aggressive aero and downforce should make the GTX taut in the turns and speedy on the straightaways. It will hit the tarmac in a handful of races this year to prove its mettle, and only 20 of them will be made this year with an eye on track-only versions for the wealthy after that.
