Some small track cars use motorcycle engines, so you'd be forgiven for thinking that the KTM X-Bow does as well. After all, it's made by a motorcycle manufacturer. But the X-Bow actually uses a turbocharged four-cylinder engine sourced from Audi to deliver as much as 295 horsepower. The latest reports, however, suggest that KTM is planning something even more powerful. The engine apparently in question is the inline-five turbo which Audi uses in the RS3 and TT RS.

In those road-going applications, the engine provides a solid 335 horsepower, but output has been increased to as much as 480 hp for racing. Speaking with Evo magazine during the Geneva Motor Show (where KTM revealed the new, more practical X-Bow GT), the company's CEO Stefan Pierer revealed that KTM is already testing X-Bow prototypes equipped with Quattro GmbH's turbo five, describing it as "very compact and fits perfectly in our chassis". Apparently KTM is even evaluating Audi's dual-clutch gearbox.
