Project Motor Racing: Building on a Legacy of Racing Sims

Project Motor Racing is being developed by Straight4 Studios, a new team founded by Ian Bell, known for his role in establishing SimBin, the studio behind GTR and GTR 2, and later for creating Slightly Mad Studios, which developed the Project CARS series. GTR 2 was often considered the benchmark for PC sim racing authenticity in the mid-2000s, while Project CARS found a broader audience by launching on consoles, supported by cutting-edge graphics technology. Straight4 brings together developer veterans who previously worked with Bell at SimBin and Slightly Mad Studios, and Project Motor Racing appears to be a spiritual successor to both series.

Project Motor Racing is built on GIANTS Engine 10 and incorporates Straight4’s proprietary “Hadron” physics engine developed from the ground-up for the sim, running at 720 Hz, with advanced combustion engine and aero modelling. Its tire model is reported to have a carcass simulation using a finite-element approach for full elastic modelling with emergent behaviors such as vibration, telescoping, and twisting, tread simulation that includes a discretized 2D contact patch, running at up to 10,000Hz, featuring tread channels for realistic water handling and aquaplaning, and a simulated steering rack used for reporting force feedback directly from the tie rod.

At launch, Project Motor Racing is set to feature more than 70 cars across 10 racing classes, supported by a wide range of officially licensed circuits. In addition to the official content, the game is planned to include full mod support through the GIANTS toolchain. This will allow players to create and share cars, tracks, and other content, extending the possibilities of the platform on both PC and console.

Project Motor Racing is designed to deliver detailed force feedback suitable for advanced sim racing hardware. For users with Fanatec equipment, the experience is expected to be well supported. Fanatec has been producing sim racing hardware for decades and is widely used by developers as a reference point when implementing wheel and pedal support. As a result, sim racing titles across the industry typically work seamlessly with Fanatec gear, and Project Motor Racing will be no exception.

Project Motor Racing is scheduled for release on November 25, 2025, for PC, PlayStation 5, and Xbox Series X|S. Its combination of official racing content, advanced physics, and planned mod support will be closely watched as it enters the competitive landscape of modern racing simulations.
