Project Motor Racing is moving beyond dedicated competition machinery and into the territory of road-legal cars engineered with the racetrack firmly in mind. Straight4 Studios has added the Lamborghini Temerario to the simulator as part of Version 2.3, bringing Lamborghini’s 907-horsepower hybrid supercar into the game alongside an entirely new Track Day class available as base-game content.

The Temerario is an unusually demanding car to reproduce accurately. Its 4.0-liter twin-turbocharged V8 can spin to 10,000 rpm, three electric motors supplement the combustion engine, the front axle uses electric drive to provide all-wheel-drive capability, and an active rear-steering system continually alters how the car responds depending on speed, driver input and available grip. Straight4 says those systems have been modeled rather than simplified into generic performance modifiers, with the new trailer placing particular emphasis on four-wheel steering.

Its arrival also gives Version 2.3 a broader significance. The update does not simply add another Lamborghini to the garage: it establishes Track Day as a new vehicle category, continues the studio’s physics revisions across existing racing classes and introduces sizeable improvements to lighting, weather, Career Mode mod support, AI, multiplayer and telemetry.

The Temerario Replaces the V10 Formula With Something Very Different

The Temerario represents a major technical shift for Lamborghini. Introduced as the successor to the Huracán, it abandons the naturally aspirated V10 associated with that model family and replaces it with a completely new 4.0-liter twin-turbo V8 hybrid powertrain developed in Sant’Agata Bolognese.

The combustion engine produces 800 CV, equivalent to roughly 789 horsepower, between 9,000 and 9,750 rpm and is capable of reaching a 10,000 rpm maximum engine speed. Lamborghini describes it as the first production super sports car capable of reaching that figure. Three electric motors then supplement the V8, bringing maximum combined output to 920 CV, or approximately 907 hp.

Two electric motors drive the front axle when required, while another sits between the V8 and the eight-speed dual-clutch transmission. That central motor can help fill the torque gap during gear changes and supplement the combustion engine’s response, while the front motors give the car all-wheel-drive capability without requiring a traditional mechanical connection from the engine to the front axle.

The resulting performance figures are suitably extreme. Lamborghini quotes 0–100 km/h in 2.7 seconds and a top speed of 340 km/h, but the more unusual engineering achievement is arguably the way the Temerario combines turbocharging and electrification with an engine that behaves more like a competition unit at the top of its rev range.

Project Motor Racing Is Simulating the Hybrid Car, Not Just Its Power Figure

Putting 907 hp into a vehicle specification is relatively simple. Reproducing why the real Temerario behaves the way it does is considerably harder, and that is the part Straight4 is emphasizing with the new addition.

The studio says the Lamborghini’s technical systems have been simulated as accurately as possible within Project Motor Racing. The hybrid all-wheel-drive architecture, high-revving combustion engine and chassis electronics therefore need to interact with the game’s underlying physics rather than simply producing the expected acceleration figures.

That distinction matters in a simulator. The Temerario weighs substantially more than the lightweight race cars that populate many of PMR’s existing classes, yet Lamborghini has engineered the real car around systems intended to conceal or exploit that mass through torque distribution, rear-axle steering and active vehicle dynamics.

A convincing virtual version therefore needs to communicate more than straight-line speed. How quickly the car rotates into a hairpin, how stable it feels under power, how the drivetrain responds when grip begins to disappear and how its electronic systems intervene are all part of what separates the Temerario from a conventional rear-wheel-drive supercar with a large horsepower figure.

Four-Wheel Steering Is the Temerario’s Main Simulation Showcase

Straight4 is focusing particularly heavily on four-wheel steering, describing it as the car’s principal technical trick inside the simulation.

The system monitors the driver’s inputs and grip conditions and changes how the rear wheels steer accordingly. At speeds below 75 km/h, PMR models the rear wheels turning by as much as 3.0 degrees in the opposite direction to the front axle.

The effect is similar to temporarily shortening the car’s wheelbase. When the front wheels turn into a slow corner and the rear wheels point slightly in the opposite direction, the car can rotate around a tighter radius than it could if the rear axle remained fixed. That should be especially noticeable through hairpins, tight chicanes and low-speed complexes.

The interesting part from a simulation perspective is that the system is not being represented as a fixed amount of rear steering. Straight4 says it is dynamically deployed according to the car’s state, meaning steering behavior should evolve with speed and available grip rather than feeling identical in every corner.

For players, that could make the Temerario deceptively agile. Its powertrain and hybrid hardware create a substantial, technologically dense supercar, but the rear-steering system is specifically intended to make it behave as though some of that physical size has disappeared when the road tightens.

The Electric Motors Are Doing More Than Adding Horsepower

The three-motor hybrid system is equally important to the Temerario’s character.

Each of the two front axial-flux motors can contribute drive to its respective front wheel, providing traction and helping the vehicle distribute torque across the front axle. The third electric motor sits behind the V8 and ahead of the transmission, supporting the combustion engine and smoothing power delivery.

This means the real car’s all-wheel-drive system is fundamentally different from a traditional mechanical AWD layout. The front axle can be managed through electric power while the V8 remains mechanically focused on the rear of the car, creating opportunities for extremely rapid changes in torque distribution.

Lamborghini’s broader vehicle-dynamics system uses this hardware together with steering, braking and other inputs to influence the car’s behavior. It can prioritize stability, traction or a more playful attitude depending on what the driver requests.

That is why reproducing the Temerario inside a simulation is more complicated than matching an engine curve and drivetrain layout. Modern performance cars increasingly use software and electronically controlled hardware as fundamental parts of their handling philosophy. If those systems are absent or heavily simplified, the car may reproduce the specification sheet while missing the engineering that gives it its actual personality.

Track Day Creates a New Home for Road-Legal Performance Cars

The Temerario also arrives with a completely new Track Day class, included as part of the base game rather than sold separately.

Until now, Project Motor Racing has concentrated primarily on machinery built specifically around competition categories and historical racing. The addition of Track Day gives Straight4 a framework for cars that occupy the space between road and race machinery: production vehicles capable of being driven legally away from the circuit but engineered to deliver serious performance once they arrive there.

The Temerario is an obvious car with which to establish that category. It remains a road-going Lamborghini with production-car equipment, hybrid technology and usability considerations, but much of its engineering exists specifically because Lamborghini expects owners to take advantage of its performance on a circuit.

That creates a fundamentally different driving challenge from a GT3 car. A GT3 machine is regulated around competition, stripped of unnecessary road equipment and designed to operate within a defined Balance of Performance framework. The Temerario carries considerably more road-car complexity and power, leaving players to manage performance that has not been standardized for racing against rival manufacturers.

The Track Day label also gives Straight4 room to expand in a direction PMR has previously explored less extensively. The studio has not yet announced a complete future roster for the category, but creating a dedicated class rather than leaving the Lamborghini isolated suggests a structure capable of accommodating additional high-performance road cars.

The Road Temerario Is Very Different From Lamborghini’s GT3 Version

The distinction is particularly interesting because Lamborghini now has a competition-focused Temerario as well.

The Temerario GT3 was developed for customer racing and is scheduled to compete internationally under GT3 regulations. Although it retains the road car’s basic chassis and 4.0-liter twin-turbo V8 architecture, the hybrid system is removed and the car is extensively modified for motorsport. Lamborghini currently lists its output at approximately 585 CV depending on Balance of Performance.

That creates two radically different interpretations of the same underlying platform. The GT3 uses reduced power, racing aerodynamics, a competition chassis specification and regulatory limits to deliver predictable race performance. The road-going Temerario in PMR retains the 920 CV hybrid system and the electronic technology Lamborghini designed for its production flagship.

For a simulator, that contrast is valuable. A race car is not automatically the faster or more difficult experience simply because it wears slick tires and aerodynamic bodywork. The road car can offer vastly greater power while simultaneously asking the driver to manage more mass, different tires, road-derived suspension and electronic systems intended to make that performance accessible.

Version 2.3 Also Reworks GT3, GT4 and LMDh Handling

The Lamborghini may headline the update, but Version 2.3 continues Straight4’s ongoing work on the rest of Project Motor Racing’s physics.

Both GT3 and GT4 receive further tire tuning, with changes intended to improve the way tires communicate the limit of adhesion and behave when cold. Straight4 has also revised directionality, aerodynamics, pitch sensitivity and stability during high-speed cornering, braking and lift-off situations.

GT4 receives additional work to differential flex and a fix for a tire-wear overflow problem. N-GT gearbox flex and handling have been updated using historical real-world data, while LMDh receives changes to tire heat generation, load sensitivity, compound separation, aerodynamic drag, brake-duct behavior and cornering stability.

Several individual cars have also been revised. The Ford Mustang GT3 receives updated Balance of Performance and aerodynamic characteristics, the Mustang GT4 gets its own BoP change, and both the Porsche 718 Cayman GT4 Clubsport and Porsche 911 GT3 R receive targeted corrections. The Aston Martin Valkyrie Hypercar has also had its default toe settings modified to reduce straight-line wandering.

The breadth of those changes makes Version 2.3 another physics iteration rather than a conventional content patch with one new vehicle attached.

Lighting and Weather Get a Significant Visual Upgrade

Straight4 has also made substantial changes to the way PMR renders its circuits across different weather and time conditions.

The environmental lighting system now accounts more directly for solar intensity, color temperature and illumination from the sky throughout the complete day-night cycle. Transitions between sunrise, full daylight and sunset have been smoothed, while nighttime scenes receive increased ambient illumination so drivers can see more consistently without eliminating the visual character of darkness.

A new physically based tone-mapping system is designed to preserve a wider range of luminance information. Bright skies, headlights, reflections and other intense highlights should clip less aggressively, while shadows and midtones retain more useful detail.

That is particularly relevant to a racing simulator because lighting is not purely decorative. Drivers use contrast, surface detail, braking markers and trackside objects as reference points, and a technically dramatic sunset is less useful if exposure makes those references difficult to read.

The changes are therefore aimed at creating a more natural-looking image while maintaining consistent visual information for the driver.

Career Mods Can Now Support Multi-Class Championships

Version 2.3 also expands ModHub, one of Project Motor Racing’s more distinctive long-term systems.

Career Mode mods can now support multi-class championships, allowing community creators to design events around multiple categories competing simultaneously rather than restricting custom championship structures to one type of car.

ModHub itself receives a search function, clearer download and update information, and automatic identification of missing mods when players attempt to join custom multiplayer lobbies. Instead of discovering that a session requires content they do not have and manually hunting for it, the game can identify the necessary items and offer them for installation.

The update also improves multi-class pit-box assignment and adds class positions to the spectator interface, both useful changes for endurance-style racing where overall position alone does not explain how a driver is performing relative to direct class rivals.

These are quieter changes than adding a Lamborghini, but they support one of PMR’s central promises: treating modded content as a more integrated part of the simulator rather than a separate ecosystem that players have to manage largely outside the game.

Console Players Finally Get UDP Telemetry

Another notable addition is the activation of UDP telemetry settings on PlayStation 5 and Xbox Series X|S.

Telemetry is particularly important for players using external dashboards, data analysis tools and other sim-racing hardware or software. Opening UDP data on consoles brings those platforms closer to the broader ecosystem PC sim racers have traditionally been able to build around their games.

The update also fixes a PlayStation 5 crash associated with returning to the pits during Join in Progress custom lobbies, while the wider multiplayer patch addresses several transition, loading and grid-behavior issues.

For a title marketed around serious simulation, telemetry support is not a superficial feature. It allows players to examine what a car is doing in considerably greater detail than the on-screen HUD can provide, which should be especially interesting when trying to understand something as technologically complicated as the Temerario.

The Temerario Arrives During a Busy September for PMR

Version 2.3 continues a particularly active period for Project Motor Racing. Straight4 released the V8 Power Pack earlier in September and added Michelin Raceway Road Atlanta shortly afterward, while smaller updates have continued addressing handling, stability and quality-of-life issues.

That ongoing work matters because PMR’s launch on November 25, 2025 was difficult. Straight4 publicly acknowledged performance and technical problems on release day and committed to improving the simulator rather than pretending those issues did not exist.

Version 2.3 arrives almost ten months later as part of that continuing process. Its patch notes still contain a substantial number of fixes, but the balance has increasingly shifted toward refining vehicle behavior, expanding functionality and adding new content rather than dealing exclusively with launch problems.

The Lamborghini therefore serves two roles. It is a headline car capable of generating attention on its own, but it also arrives inside an update that illustrates how much of PMR is still being actively iterated.

Track Day Could Become an Important New Direction for Project Motor Racing

The most interesting long-term element may ultimately be the two words sitting beneath the Temerario in the patch notes: Track Day.

Project Motor Racing was built around professional-level motorsport simulation, and its identity remains rooted in racing machinery. A dedicated Track Day category gives Straight4 a way to preserve that track-focused philosophy while introducing road cars sophisticated enough to be interesting from a simulation standpoint.

The Temerario demonstrates the possibilities immediately. Its appeal is not simply that it produces more than 900 horsepower. It requires the simulation to account for a 10,000-rpm turbocharged engine, three electric motors, electric all-wheel drive and rear-wheel steering that actively changes the effective behavior of the chassis.

Those are exactly the kinds of systems that distinguish modern supercars from the mechanically simpler performance cars of previous generations.

If Track Day develops into a larger category, it could give PMR an additional type of driving experience: cars that are technically production vehicles but whose engineering is sophisticated enough that extracting their maximum performance on a circuit remains a serious challenge.

For now, there is one exceptionally loud starting point.

The Lamborghini Temerario is available now in Project Motor Racing Version 2.3 as free base-game content, bringing 907 hp, 10,000 rpm and four-wheel steering to a simulator that now has an entirely new class in which to use them.
