Kylotonn

Kylotonn is a French video game developer specializing in motorsports, racing games and real-time automotive simulation. Founded in 2006, it operates development studios in Paris and Lyon and produces games for consoles and PC. The company also uses the KT Racing label for its racing productions.

Its development capabilities span game design, engineering, 3D art, vehicle physics, quality assurance and post-launch support. Its racing portfolio encompasses rally competition, circuit racing, motorcycle simulation and open-world driving, combining vehicle handling systems with environments designed around different forms of motorsport.

Racing development

The studio refocused its operations on motorsports in 2014. Working with publisher Bigben Interactive, it began developing the official FIA World Rally Championship games with WRC 5 in 2015. Its subsequent work included successive WRC releases through WRC Generations, alongside V-Rally 4 and the first two TT Isle of Man: Ride on the Edge games.

Kylotonn later developed Test Drive Unlimited Solar Crown, released in September 2024 for PC, PlayStation 5 and Xbox Series X/S. The project brought its racing development experience to an open-world driving and lifestyle franchise. As of the supplied November 2026 research, the studio continues post-launch support for that game while developing Endurance Motorsport Series.

Technology and development history

The studio develops its own KT Engine, a proprietary real-time 3D technology platform used for its games and simulation work. Its activities also extend into automotive engineering research through KT Automotive, applying game technology to industrial simulation.

Kylotonn's roots lie in the earlier 4X Studio, whose directors regrouped to establish the company in 2006. Before its motorsport focus, Kylotonn worked on action games, including The Cursed Crusade. Bigben Interactive completed its acquisition in 2018, and Kylotonn subsequently became part of the Nacon development group. This history connects its earlier action-game development with its later concentration on racing and simulation technology.
