- 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.
Project Motor Racing v1.6.0.1 update changelog
Physics & Handling
- Implemented a more robust throttle response system.
- Revised Downshift Protection: Simplified the logic to be more reliable and added a percentage allowance for over-revving to make it less restrictive.
- Fixed issues with automatic gears and throttle blip assist for better stability during downshifts.
- Lowered Tyre Pre-heating temperatures across all classes.
GT3
- Updated tyre model to provide a more realistic representation of slip and grip angles, improving behaviour at and beyond the limit.
- Reworked Traction Control (TC) and Antilock Braking System (ABS) logic to allow more natural lateral slip while reducing excessive longitudinal slip, improving overall balance and driveability.
- Due to these changes, players are advised to review and refine existing custom setups for this class.
LMDh
- Full Traction Control (TC) rework to improve consistency and usability.
- TC settings 2 through 10 now offer a more meaningful and usable range (Note: Setting 1 is currently bypassed/off).
- Improved downshift protection behaviour.
- Fixed an issue that could cause the engine to stall when shifting into neutral.
GTO
- Relaxed Traction Control (TC) settings to allow more performance and driver influence at the limit.
Group 5 & Group C
- Adjusted Traction Control (TC) slip angles for improved stability under load.
- Increased clutch slip on downshifts to improve stability during aggressive deceleration.
- Input & Force Feedback
- Logitech TrueForce is now disabled by default on PC.
- Force Feedback (FFB) strength balanced across GT3 class for a more consistent baseline feel.
- Fixed an issue that prevented setup selection via mouse input when large numbers of setups were present.
- Improved Force Feedback (FFB) on wet track conditions.
UI
- Fixed incorrect constant data being sent via UDP.
- Improve navigation and readability in the player stats menu
Online & Multiplayer
- Fixed an issue causing opponent cars to ghost unexpectedly during online races.
- Fixed a bug that could result in players joining an unintended lobby.
AI Opponents
- Increased grid capacity at São Paulo to support up to 32 AI vehicles on PC.
- Improved racing line behaviour across multiple circuits.
Tracks & Environment
- Optimised tree rendering and placement for improved visuals and performance.
- Adjusted track penalty trigger zones for more consistent detection.
- Improved the Racing Line assist across multiple tracks.
Vehicle Art
- Various small art fixes on several vehicles.
- Corrected MoTeC display number flickering on multiple cars.
- MoTeC displays now receive correct tyre temperature data.
- Polished several driver animations.
