Project Motor Racing — Version 2.3

This new update introduces the Lamborghini Temerario and the Track Day class, plus some vehicle and handling refinements based on community feedback, along with multiple improvements to gameplay, the ModHub section and more.

What's new

Version 2.3 primary focus is delivering further stability and improvements across multiple aspects of Project Motor Racing.

Highlighting this update is the addition of the Lamborghini Temerario to the base game, along with a new class.

Expanded supported to the ModHub, including multi-class support for Career Mode mods, along with enabling UDP telemetry on consoles.

Multiple fixes have been implemented based on community feedback, along with further vehicle and handling refinements. Don't worry, your previous custom setups still work.

Lamborghini Temerario

Lamborghini’s newest supercar comes to Project Motor Racing, complete with all its cutting-edge technology. At its heart is an all-new 4L twin-turbo V8 producing 789HP on its own and revving all the way to an extraordinary 10,000 RPM, backed up by three electric motors for around 907HP combined. All-wheel drive, hybrid punch, and race-engine revs in a road car. Pure Lamborghini energy.

[/carousel]In Project Motor Racing all its technical advances are simulated as accurately as possible. Its main party trick is the four-wheel steering. Constantly monitoring driver inputs and levels of grip, this system actively deploys phased steering when needed. Below 75 km/h, the rear wheels steer up to 3.0° in the opposite direction to the fronts, effectively shortening the wheelbase for tighter rotation through hairpins and low-speed complexes.

With it also comes the Track Day class as part of the base game content.

Visuals and Weather

Significant improvements have been made to rendering and weather systems.

The environmental lighting model now simulates solar intensity, colour temperature and sky-driven illumination throughout the full diurnal cycle. Smoother temporal transitions and improved low-light exposure provide stable visibility from sunrise through night racing, while preserving a natural atmospheric response.

Meanwhile changes made to tone-mapping has improves luminance mapping, contrast response and colour reproduction across the full dynamic range. Trackside detail remains legible in high-intensity skies, specular reflections, shadowed areas and headlight illumination, producing a more consistent visual reference.
