Bsimracing Sim Racing Resources and News for the racing enthousiast.
Straight4 Studios has released Update V2.0.0.4 for its Project Motor Racing title, introducing improvements to physics and handling, behaviour of AI Opponents, multiple fixes, plus added support for more input devices.
Check out the full changelog for all the details.
Special attention has been given to the LMDh class with this update. Elevating the cars in this class to a much higher standard. The ICE (Internal Combustion Engine) has been revised and recalibrated across all cars in this class, with updates to engine braking behaviour and fuel rate. This delivers more believable off-throttle response, smoother transitions into corner entry, and more representative fuel usage over race distance.
Along with that, the ECU has improved with a revised deployment and regeneration logic. These changes improve how the powertrain responds under acceleration and braking, resulting in cleaner gearshifts and more predictable energy recovery behaviour from the hybrid system.
In addition to upgrading the tyre model to match what other classes received since Update 2.0, and currently only in LMDh, brake heat transfer now feeds more accurately into tyre temperatures, linking braking workload more directly to tyre performance. Heavy braking zones will now contribute more clearly to tyre warm-up and temperature management, adding another layer of realism to race pace, consistency, and setup decisions. Future updates will have this element expanded into other classes.
Substantial improvements have been made to the way the suspension behaves that further enhance the feedback between car and driver. For cars that use the Multi-link type of rear suspension, the way the suspension communicates to the driver the surface of the road, and how the car is reacting, has been improved so that you can more easily understand and react in real time.
The suspension’s progressive bump stop behaviour has been significantly improved to produce a more natural load build-up at the limits of travel. This helps the car feel more composed over kerbs, under heavy compression, and during rapid direction changes, while giving drivers clearer feedback near the edge of grip. This sets the foundation to expand in future updates, and is of particular use for tuning aero pitch sensitivity on cars with more advanced aerodynamics.
To help you understand what’s happening, a new bumpstop visual indicator has been introduced into the HUD. As a spring compresses into a bumpstop, the colour becomes progressively redder, indicating how close it is to its limit.
