Project Motor Racing groups its top-tier endurance prototypes under the LMDh class banner, featuring nine licensed modern hypercars from manufacturers competing in WEC and IMSA. While the sim labels all nine under the LMDh category, the grid mixes genuine LMDh chassis regulations with bespoke LMH machinery like the Toyota GR010, Peugeot 9X8, and Aston Martin Valkyrie. Following major physics revisions across updates up to Version 2.2, these prototypes feature distinct handling dynamics, engine behaviors, and hybrid deployment characteristics.
Full Roster and Engine Specifications
On paper, modern hypercars share strict Balance of Performance (BoP) limitations around 670–680 horsepower, but their internal combustion powertrains and architectural designs differ substantially.

Official game data documents exact engine layouts across the category, highlighting that the naturally aspirated V12 Valkyrie and large-displacement V8 Cadillac deliver distinctly different acoustic and throttle profiles compared to the smaller-capacity twin-turbo V6 machines.
Prototype Handling Profiles and Driving Characteristics
Testing across community drivers and sim analysts demonstrates that each prototype behaves differently on track, particularly when running default setups on direct-drive wheels or standard gamepads.
- BMW M Hybrid V8: Regarded by testers as one of the most balanced, stable all-rounders in the class. It resists sudden snaps on corner entry, handles long stints predictably, and offers an extensive setup window that makes it especially manageable on controllers.
- Toyota GR010 Hybrid: Characterized in-game and during long runs by calm, drama-free speed. Its power delivery and stability favor rhythm driving and tire conservation over aggressive rotation.
- Porsche 963: Offers sharper responsiveness and a greater willingness to rotate into turns than the BMW. It demands smoother steering and throttle discipline but rewards drivers who prefer an agile front end.
- Cadillac V-Series.R: Described in official vehicle documentation as a rhythm car. The naturally aspirated 5.5L V8 provides immediate, linear throttle response with 740 Nm of torque, eliminating turbo lag transitions on corner exit.
- Acura ARX-06: Built around a high-revving 2.4L twin-turbo V6 spinning up to 9,500 RPM. It features immediate front-end response, making it suitable for drivers who prioritize sharp corner turn-in.
- Alpine A424 and Peugeot 9X8: The French entries utilize compact V6 powertrains (3.4L single-turbo and 2.6L twin-turbo, respectively). The Peugeot offers unique aerodynamic behavior derived from its distinct chassis package, while the Alpine provides a lightweight mid-engine alternative.
- Aston Martin Valkyrie: Operates as the structural outlier of the class with its 6.5L naturally aspirated V12 revving to 10,500 RPM. Early gameplay testing revealed high corner-entry resistance under heavy braking, requiring precise trail-braking management or pad-driving parameter adjustments.
Physics Overhaul and Technical Mechanics
The hypercar class underwent significant physics overhauls in Update 2.0.0.4 and Version 2.2, addressing early player critiques regarding brake lockups, intrusive oscillations, and low-speed stability.
Hybrid Powertrain and Brake-by-Wire
Version 2.2 fundamentally altered the interaction between the Internal Combustion Engine (ICE) and the Motor Generator Unit (MGU):
- Dynamic Brake-by-Wire: The hybrid braking system automatically shifts brake balance dynamically in real time to compensate for changes in vehicle speed, aerodynamic downforce, and regenerative energy recovery.
- G-Force Adaptive Regeneration: MGU regeneration levels scale down automatically under high lateral G-forces to prevent regenerative torque from destabilizing the rear axle during mid-corner transitions.
- ABS Compatibility: Antilock braking assist functions in both Safe Regen and Full Regen modes at any electrical recovery rate.
- Powertrain Smoothing: Revised engine inertia and deployment logic eliminate the severe engine oscillations previously triggered when the MGU deployed power under steady throttle.
Aerodynamics and True2Track Integration
Prototypes in Project Motor Racing rely on Straight4's Hadron physics engine operating alongside the dynamic True2Track surface model:
- Pitch Sensitivity and Stall: The updated aero model enforces the real-world 4:1 aerodynamic efficiency ratio. Setting static ride heights excessively low causes underfloor aerodynamic stalling over bumps and compressions, reducing downforce rather than boosting grip.
- Dynamic Grip Surfaces: The True2Track engine calculates dynamic water depth, rubber build-up along the racing groove, and loose rubber marbles off-line. Passing over marble deposits directly reduces friction in the physics solver.
- Progressive Bumpstops: The multi-link suspension incorporates progressive bumpstop resistance to prevent sudden chassis bottoming over kerbs. A visual HUD indicator displays compression levels, turning progressively red as travel reaches its mechanical limit.
Three-Compound Tire Model
The reworked prototype tire model features three distinct slick compounds. The primary distinction between compounds is not sheer peak grip, but rather heat generation rates, operating temperature windows, and pressure build-up. Additionally, brake heat transfer actively warms the wheels, meaning heavy braking zones feed directly into tire core temperatures.
Online Licensing, Career Mode, and Challenges
Accessing hypercars across Project Motor Racing's various game modes requires understanding specific progression rules, mode settings, and hardware options.
Unlocking Hypercars in Ranked Online
Ranked online multiplayer enforces strict progression to ensure grid standards:
- Complete the mandatory online license test at Lime Rock Park, achieving an eight-lap benchmark in or under 8:20 against AI.
- Compete in scheduled online championships with 0–100 driver skill rating divisions.
- Secure a race win in any split of a ranked championship series to unlock the ability to enter official Group C and LMDh online events.
Career Mode and Factory Driver Challenges
In Authentic Career Mode, players can jump directly into high-tier prototypes if they select the highest starting narrative budget tier ($2,000,000 or the expanded historic budget), bypassing lower ladder classes like GT4 or GT3. In this mode, mid-session restarts are disabled, and players must fund operational damage repairs and race travel costs directly from prize money and sponsor archetype payouts. Winning an Authentic Career championship in this car class awards The Pinnacle achievement, while completing 300 km behind the wheel unlocks the LMDh License achievement.
For solo leaderboard competition, the Factory Driver mode provides rotating two-week challenges featuring fixed car-and-track combinations, such as the Aston Martin Valkyrie at Daytona or the Peugeot 9X8 at São Paulo Autódromo.
Frequently Asked Questions
Which hypercars are included in the Project Motor Racing LMDh class?
The roster features nine prototypes: Aston Martin Valkyrie, Cadillac V-Series.R, BMW M Hybrid V8, Porsche 963, Toyota GR010 Hybrid, Acura ARX-06, Alpine A424, Peugeot 9X8, and Lamborghini SC63.
Are VR and Triple Screen supported for hypercar cockpit driving?
Yes. As of Version 2.2, VR and Triple Screen support transitioned from experimental Alpha to Beta status. Both settings can be toggled directly within the standard PC in-game options menu without entering custom command-line launch parameters. Console VR is currently not supported.
Why do old hypercar setups feel unstable after recent updates?
Recent patches rebuilt the progressive bumpstop curves, tire heat generation, brake-by-wire logic, and pitch-sensitive aerodynamics. Straight4 Studios recommends resetting cars to their updated default setups or sourcing revised setups through the in-game ModHub, as pre-overhaul tunes often conflict with the revised physics calculations.
What are the PC system requirements to run Project Motor Racing?
Minimum requirements require Windows 10 (64-bit), an Intel Core i7-8700 or AMD Ryzen 5 processor, 16 GB of RAM, 75 GB of storage space, and an NVIDIA GeForce RTX 2060 or AMD Radeon RX 580 (6 GB VRAM). Recommended specs list Windows 11, an Intel Core i7-10700 or AMD Ryzen 7 processor, 24 GB of RAM, and an NVIDIA GeForce RTX 3070 or AMD Radeon RX 6800 (8 GB VRAM).
