Further Enhancements to LMDh
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 been given a recalibration 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, 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.
[img src="{STEAM_CLAN_IMAGE}/45601812/382710fcab2b673d5e293d86afc210f8dc8d7972.jpg"]
Suspension and Progressive Bumpstop
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 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 more red, indicating how close it is to its limit.

Additionally, from 1 April, Ranked Online will feature all car classes in PMR, including DLC.
A Career with Direction
With Update 2.0 Career Mode gets a massage. It’s no longer just a loose sequence of events—it’s now more of journey built around growth, survival, and achievement.
Players build toward a long-term racing legacy and new to the mode comes: real-world sponsors (such as Liqui Moly), improved event messaging and presentation, podium ceremonies, trophies, and a new endpoint to your career.
[img src="{STEAM_CLAN_IMAGE}/45601812/a9181c369af8f5d8569487aeabac24c59980364d.jpg"]
Refined Driving Physics
At the heart of Update 2.0 is a significant step forward in handling. Working alongside experienced sim racers, dedicated test drivers, and sim racing developers, the focus has been to make the cars communicate more clearly, evolve the tyre model into something that feels and drives far more authentically, and leaning into authentic car characteristics.
Building and evolving from the tyre model introduced in previous updates for the GT3 and GT4, Update 2.0 extends this to the Porsche 992 Cup, GT, GTE, and N-GT class. N-GT has the most evolved tyre and should serve as the reference point for the future of PMR. Further rollout across additional classes will follow in upcoming patches.
Also rebuilt, from the differential to suspension and tyres, is the Mazda MX-5 Cup.
Deeper Insight: The ECU Widget
Update 2.0 also introduces the ECU Widget — a real-time telemetry system available on your HUD. It visualises all sorts of vitals: tyre load and weight transfer, aerodynamic balance, drivetrain power delivery and a whole lot more.
Fuel usage and stint strategy is also available via this widget.
Please note: the portion of the ECU Widget, engine mapping, is currently only functional in LMDh cars. We will make this function compatible with other cars in a future update.
Alongside it, the new FFB Widget provides a deeper view into force feedback behaviour, helping you fine-tune your setup with greater precision.
You can learn how to use both these new tools in this blog: ECU Widget Explained

Update 1.6.0.1 continues our ongoing work to improve stability, driving feel in Project Motor Racing, while addressing several issues raised by the community.
[img src="{STEAM_CLAN_IMAGE}/45601812/6a437e7f8d92b51a47d572b8d605730065746292.jpg"]
The primary focus of this update is a substantial evolution of the tyre model in the GT3 class. This work brings the GT3 cars closer to their intended driving behaviour, with more accurate slip and grip angles, clearer feedback at the limit, and a far more natural transition between grip and loss of traction.
The goal is to deliver a more believable, consistent, and accurate driving experience, particularly when pushing at race pace.
As with previous physics revisions, this change affects the balance of existing setups. Custom car setups for GT3 cars created prior to this update may no longer behave as intended and will likely require adjustment to suit the revised tyre and vehicle behaviour.
Additionally, this patch brings Force Feedback (FFB) strength balancing across the GT3 class for a more consistent baseline feel as a default.
Below is a full breakdown of what’s included in Update 1.6.0.1.
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.
[img src="{STEAM_CLAN_IMAGE}/45601812/2b355f62ac429b567d7bdc42fe80f987ed57b4db.jpg"]

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.
Thank you for your support. We hope you continue to enjoy Project Motor Racing.
Patch 1.6.0.0 brings multiple stability and performance improvements. The focus is on improving driving behaviour for the LMDh class based on community feedback.
[img src="{STEAM_CLAN_IMAGE}/45601812/17c923339dd9d9ca0ee2149a22c726a6fa61b9f2.jpg"]
With this update, the default brake bias has been shifted closer to a true 50/50 split, alongside changes to rear brake sizing, to better reflect real-world data. This means older setups that were built around the previous bias may now feel unstable under braking, particularly into heavy braking zones or trail braking situations.
Players using their own setups in LMDh, GT3, GT4, and the 992 Cup cars will want to revisit their brake balance settings.
Additionally, the LMDh class has received a substantial round of physics and drivability improvements aimed at making these cars more predictable, rewarding, and realistic across a wide range of conditions.
Be sure to check Information Regarding Car Setups in Project Motor Racing Update 1.6.0.0 for a detailed breakdown of these changes and improvements.
Other noteworthy improvements in this update includes various improvements to the online components that provides a more stable experience. Along with the weather system and time-of-day now being enabled in Career Mode. Meaning that the start times and weather conditions will be different each time.
