Project Motor Racing Version 2.3 Adds Lamborghini Temerario and Track Day Class

Project Motor Racing has received Version 2.3, a new update that brings the Lamborghini Temerario and the Track Day class to the base game, along with vehicle and handling refinements based on community feedback, and improvements to gameplay, ModHub, rendering, and more.

What's New

The update's main focus is delivering further stability and improvements across multiple areas of the game. Besides the new car and class, it expands ModHub support — including multi-class support for Career Mode mods — and enables UDP telemetry on consoles. Previous custom setups remain compatible.

Lamborghini Temerario Joins the Grid

Lamborghini's newest supercar arrives with an all-new 4L twin-turbo V8 producing 789 HP on its own and revving up to 10,000 RPM. Backed by three electric motors, the hybrid all-wheel-drive setup delivers around 907 HP combined.

The game simulates the car's technical features as accurately as possible, with its four-wheel steering system as the highlight. By monitoring driver inputs and grip levels, the system 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 sections.

The new Track Day class also arrives as part of the base game content.

Visual and Weather Improvements

Rendering and weather systems have received significant upgrades. The environmental lighting model now simulates solar intensity, colour temperature, and sky-driven illumination across the full day-night cycle, with smoother transitions and improved low-light exposure for stable visibility from sunrise through night racing.

A new physically based tone mapping system improves luminance mapping, contrast, and colour reproduction across the full dynamic range, keeping trackside detail legible in bright skies, reflections, shadowed areas, and headlight illumination.
