As work on Project Motor Racing continues, Straight4 Studios has outlined the first few details of the all-new physics engine set to power the title, called Hadron.
Just after teasing another car that looks to join its roster in the Mosler MT900 R, Straight4 Studios lifts the hood on Project Motor Racing somewhat. It has already been known since last summer that the title would use GIANTS Engine as part of the publishing deal with GIANTS Software, but now, the studio shared the first few details about the all-new physics engine it uses with the sim.
Called Hadron and developed just for the title, it looks to offer very in-depth simulation capabilities. According to Straight4 Studios, it goes as deep as a fluid dynamic simulation that allows for turbo lag, backfires and certain defects to be simulated accurately. Other highlights include an extremely in-depth tire model that aims to deliver a detailed FFB feel as well as handling characteristics.
It seems like the Hadron physics engine will focus particularly on how the numerous elements that influence a car's handling are interconnected, as the drivetrain and aerodynamics simulation entries on the list indicate. In racing, the old saying that no two laps feel exactly the same is frequently heard - and on paper, it looks like Hadron will try to really lean into this.
As Project Motor Racing is supposed to be released in 2025, sim racers keep wondering about the game - not much has been seen other than a few screenshots, but the details of the physics engine released now could hint at more to come relatively soon.
It is safe to say that many sim racers are curious about finding out more, as was evident in the comments under our article on the Mosler teaser. @VFXPro, for instance, is wondering when a video of Project Motor Racing might finally be shown. Meanwhile, others are liking the inclusion of cars that were in GTR and GTR2 roughly 20 years ago, as the latter in particular is still looked upon fondly.

Project Motor Racing: Hadron Physics Engine Highlights
- First principle physics engine delivers unmatched handling realism at 720Hz
- A new open topology multi-body vehicle solver
- Internal combustion engine and turbocharger model using a one-dimensional compressible fluid dynamic simulation that allows for effects like turbo lag or backfires, and defects like dieseling or knocking, with exhaust gas that impairs the virtual airspace around the car
- More natural, non-linear throttle control due to torque response that is dynamically emerging from the fluid and combustion simulation
- Modular drivetrain, running at 7,200Hz, supporting all clutch, differential and gearbox configurations
- Accurate FFB taken directly from the tie rod
- Fully dynamic tyre simulation, comprising:
- Carcass simulation using a finite-element approach for full elastic modelling with emergent behaviours such as vibration, telescoping, and twisting
- Tread simulation that includes a discretised 2D contact patch, running at up to 10,000Hz, featuring tread channels for realistic water handling and aquaplaning
- Simulated steering rack used for reporting force feedback provides a detailed and nuanced handling feel for the driver
- Piecewise aerodynamics model where wings, winglets or the undertray can affect each other
