The KTM X-Bow was a series of track focused sports cars introduced in 2008. The X-Bow, pronounced Crossbow, was KTM's first car. Initially, this series of cars were powered by a mid-mounted 2.0L turbocharged inline four engine, but from 2013, a larger 2.5L inline five unit was used. The X-Bow was originally offered as an open top two seater, but a hardtop version prepped for GT4 class racing was introduced later in the models life.
