2020
The X-Bow GTX is a longer wheelbase track-only race car version released in October 2020, manufactured in collaboration with Reiter Engineering. Aesthetically, the design is very different to the standard X-Bow. The car uses a different engine to the standard X-Bow, making use of a 2.5-litre Audi TFSI 20-valve I5 engine sourced from the Audi RS3. The 6-speed Holinger sequential transmission and carbon fiber monocoque are retained. The inline-5 engine receives a number of upgrades for racing, including upgrades to the engine management system, injection valves, waste gate, intake, and exhaust. The fuse box comes from Reiter's subsidiary company Sareni United. It also comes with fully electric power steering.
