- New version of GT3 tyre model in PMR
- Improved slip and grip angles for more realistic handling
- Traction control fixes for GT3, Group C, GTO and Group 5 classes
Straight4 Studios has released a new update for Project Motor Racing today (19th February 2026), which apparently introduces a comprehensive overhaul of the game’s GT3 tyre model.
The beleaguered sim, which is aiming for redemption after a less-than-stellar launch, has also introduced several new tweaks to improve its physics, including improved throttle response and downshift protection systems.
The LMDh class, which received a new handling model in an update last week, has also had its traction control system reworked to improve usability, along with those of the GTO, Group 5 and Group C categories.
However, significant work has been done on the GT3 class, with slip and grip angles revised to provide a more realistic depiction of sports car handling. It’s said this will improve car behaviour at the limit of adhesion, with players advised to revisit previously saved car set-ups to account for the changes.
More quality-of-life fixes have also been implemented, including UI and multiplayer adjustments, with the full changelog listed below.
