01. Engine & Drivetrain
The wheelbase of the KTM X-BOW GT4 has been extended by as much as 17cm to suit the requirements of international customer racing. The significant change achieved by extending the rear frame means the vehicle is faster in the corners, and has improved rear axle driving stability. This, in turn, is now constructed of tubular steel instead of aluminum, which increases the torsional rigidity.
Pure GT3 technology for use in GT4 races: The sequential 6-gear Holinger transmission not only allows gear changes in the area of a millisecond range but also offers an automatic change-up, and double-declutching when changing down. Gear changes are carried out via the paddles attached to the steering wheel. Despite this sophisticated technology, the Holinger transmission weighs 35 kg less than a standard gearbox.
The KTM X-BOW GT4 comes with two different versions of the drive shaft. The standard drive shafts are designed for sprint races, while the “HD" drive shafts have been specially developed for endurance racing, or for races from a standing start.
