The X-Bow was the first mass-produced car in their product range and was unveiled and launched at the Geneva Motor Show in 2008.

KTM developed its X-Bow road cars in collaboration with design studio KISKA, Audi, and Dallara.

The car's Audi inline-4 is more powerful than the older X-Bow it replaces, tuned to produce 300 hp (224 kW; 304 PS) and 295 lb⋅ft (400 N⋅m).

[13] The car maintains the 2.5-litre Audi TFSI 20-valve I5 from the GTX, now producing 493 hp (368 kW; 500 PS) and 429 lb⋅ft (582 N⋅m) of torque, with power delivered through a 7-speed DSG gearbox.

Marcus Clutton and Phil Keen won the Supersports category with a modified X-Bow in the 2009 British GT Championship.

[16] Catharina Felser, Christopher Haase, and Dennis Retera took a podium finish at Monza,[17] and pole position in the wet qualifying session at Nogaro.

[18] Peter Belshaw and Marcus Clutton were the GT4 champions in the 2011 season of the British GT Championship in a modified X-Bow.

It also powered Brett Sandberg to the 2016 Pirelli World Challenge GTS Championship with multiple wins.

The update was directed towards increasing the car's straight-line speed while maintaining the cornering capabilities of the previous X-Bow GT4.

In a March 2012 episode of Top Gear, presenter Jeremy Clarkson drove a X-Bow GT around Donington Park circuit in England.

He applauded the tyres' grip, saying during a James May-inspired session of doughnuts, "it's like driving on superglue", but both May and Clarkson criticised the complicated procedure needed to start the engine, calling it "idiotic".
