The X-Bow was introduced in 2008 by KTM as a series of track focused sports cars. 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. Over the years the X-Bow was available in different versions such as the Base Model, Dallara, R, RR, GT, GT4, GTX, GT2, GTX-XR.
