Today, Project Motor Racing Version 2.3 officially went live, introducing the Lamborghini Temerario and the new Track Day class to the base game.
Project Motor Racing Version 2.3 brings a wide range of improvements across vehicle handling, gameplay, visuals, career mode, AI, ModHub, and online features. Developers have focused on stability and refinements based on community feedback, and confirmed that all existing custom vehicle setups remain compatible.
The Lamborghini Temerario arrives with a hybrid powertrain, combining a 4.0-liter twin-turbo V8 rated at 789 horsepower and three electric motors for a total output of about 907 horsepower. The car also features four-wheel steering, with the rear wheels turning opposite to the front below 75 km/h to help navigate tight corners.
Project Motor Racing Version 2.3 also introduces significant improvements to rendering and weather systems, including a new physically based tone-mapping system, improved lighting transitions, greater dynamic range preservation, and more natural color-temperature changes throughout the day-and-night cycle. These changes are intended to improve visibility and visual consistency across different lighting and weather conditions, including sunrise, sunset, night racing, bright skies, reflections, and headlights.
Driving physics have been refined across multiple classes. GT3 and GT4 cars now feature improved tire behavior, better cold-tire grip, enhanced directionality, aerodynamics, and high-speed stability. LMDh cars see changes to tire heat, compound separation, aerodynamic drag, brake-duct function, and braking stability.
Individual vehicles like the Aston Martin Valkyrie Hypercar, Ford Mustang GT3 and GT4, Porsche 718 Cayman GT4 Clubsport, and Porsche 911 GT3 R have also received setup, performance, or Balance of Performance updates. Project Motor Racing Version 2.3 gameplay improvements address issues with fuel calculations, pit-box assignments, penalties, starting-grid positioning, pit-to-car engineer radio triggers, and Race Weekend stability.
Replays and spectating have also been expanded with class positions, improved leaderboard sorting, corrected timing displays, synchronized animations, the ability to switch between cars before all drivers finish, and diagnostics for missing vehicles or tracks. The ModHub has received several quality-of-life upgrades, including a search function, clearer information on installed and updated mods, download and installation counts, and automatic identification of required mods when joining custom lobbies.





Career Mode now supports multi-class championships, while additional fixes address repair costs, vehicle purchases, championship progression, podium presentation, and night-race lighting. AI opponents have also been adjusted, including improvements to the Nürburgring 24 Hours pit line and pit-exit behavior, aerodynamic handling, performance-envelope generation, and GT3 top speeds.
AI pace and balance have been updated for GT3 and LMDh vehicles to reflect the latest changes to player-controlled cars. Additional fixes in Project Motor Racing Version 2.3 cover tracks, online multiplayer, and consoles, with improvements to São Paulo Autódromo and Michelin Raceway Road Atlanta, fixes for several multiplayer crashes and race-start issues, and a PlayStation 5 fix related to returning to the pits during Join in Progress sessions.
Console players can also now enable UDP telemetry settings. For more information on previous Project Motor Racing updates and other racing simulators, like Forza Horizon 6, iRacing, and Screamer, be sure to check back to Simulation Daily.
