The FIA, the ACO and IMSA announced in Le Mans the framework that will govern the top prototype category from the 2030 season. The central point is the total elimination of all‑wheel drive. All Hypercars and GTPs will be exclusively rear‑wheel drive and will feature a mandatory hybrid system, whether developed in‑house or supplied by a single provider.

Common platform and development bifurcation

The new regulatory framework establishes a common platform that merges the two current philosophies. Manufacturers will be able to develop their own chassis from scratch or opt for the base structure of an approved constructor. The authorised suppliers are Dallara, Ligier, Multimatic and ORECA. This bifurcation preserves the essence of the current LMDh model but incorporates the design freedom that manufacturers competing under LMH regulations defended.

The target power will increase by approximately 20 kW compared to the current cycle, putting the figure at around 520 kW combined between the combustion engine and the electric system. Engines will continue to be manufacturer‑specific, with total freedom in architecture and displacement. The organisers consider it essential to preserve the mechanical diversity and the sonic identity of the championship through that margin of decision.

Performance updates will be banned throughout the homologation cycle, set at a minimum of five years. Only modifications linked to reliability or safety will be authorised. The aerodynamic window will be narrower to facilitate the work of the Balance of Performance.

What Toyota, Ferrari and Peugeot lose

Three manufacturers that built prototypes with hybrid all‑wheel drive will have to redesign their vehicles from the base architecture. The Toyota GR010 Hybrid, the Ferrari 499P and the Peugeot 9X8 use an electric motor on the front axle that is activated above a certain speed (set by regulation) to turn the vehicle into all‑wheel drive during specific acceleration phases. That mechanical advantage will disappear completely.

Any successor to the GR010, the 499P or the 9X8 will have to be strictly rear‑wheel drive, with the hybrid system coupled to the rear axle. The advantage that these manufacturers enjoyed in low‑grip conditions or when exiting slow corners, particularly useful on circuits like Sebring or in the early hours of Le Mans with cold asphalt, will be removed from the regulations.

Ferrari had been explicit about its conditions for continuing beyond 2029. Antonello Coletta, the brand's head of endurance, stated that its stay depended on preserving the ability to build the entire vehicle in‑house. The new regulations grant that margin, although they require abandoning the front‑axle drivetrain concept that distinguishes the 499P. Toyota and Peugeot also did not hide their preference for keeping in‑house development of the hybrid system, and both retain that possibility within the new framework, albeit without the all‑wheel drive that defined their current projects.

LMDh cars are already the majority on the 2027 grid

The 2030 regulations respond to the projected entry numbers for 2027. Of the ten confirmed manufacturers, six will compete under LMDh regulations: Alpine, BMW, Cadillac, Genesis, Ford and McLaren. The remaining four (Toyota, Ferrari, Peugeot and Aston Martin) make up the LMH bloc. Already 60% of the grid operates under a shared‑platform model, and the new regulations bring the category closer to that scheme without completely eliminating the possibility of developing own‑brand components. This is a balance that seeks to retain the manufacturers that invest most heavily in in‑house development.

Genesis and Ford recently confirmed their partnership with Oreca for their LMDh programmes. McLaren developed the MCL-HY under the same regulations. The market trend, measured in concrete investment decisions, points toward the common architecture that is now becoming the standard for the entire category.

The Aston Martin Valkyrie, conceived with an atmospheric V12 engine without hybrid assistance, could not compete under the 2030 rules in its current configuration. Hybridisation will be mandatory for all participants without exception.

Fewer variables for the Balance of Performance

The main motivation for the new regulations is to reduce the complexity of the BoP. In recent years, those in charge of the FIA and ACO BoP have had to balance vehicles built with radically different philosophies: own‑brand chassis versus supplied chassis, front hybrid systems versus rear systems, and aerodynamic concepts with varying degrees of freedom.

That structural discrepancy generated recurring controversies. Peugeot openly criticised the regulatory changes after the LMH‑LMDh convergence, arguing that the original concept of the 9X8 was conditioned by changes that did not exist when the project began. Toyota expressed concern about certain BoP adjustments over several seasons. The very nature of Le Mans, with a specific BoP different from the rest of the championship, added an extra layer of friction.

With a common platform, adjustments will be applied on a much more homogeneous baseline. The reduced aerodynamic window and universal rear‑wheel drive eliminate two of the variables that introduced the most dispersion into performance calculations. Differences between manufacturers will depend mainly on engine efficiency, the integration of the hybrid system (own‑brand or standard), and aerodynamic execution within the permitted design zones.

Door open to dual WEC‑IMSA programmes

The current regulations already allow an LMH to compete at the 24 Hours of Daytona. Aston Martin confirmed this with the Valkyrie. The existence of differences between the two rulebooks made simultaneous operation in both championships more expensive, and the single platform removes that economic and logistical obstacle. A single vehicle designed under the 2030 rules will be able to run the 24 Hours of Le Mans, the 24 Hours of Daytona, the 12 Hours of Sebring and Petit Le Mans without needing specific adaptations for each championship.

For Toyota or Ferrari, which historically focused their efforts on the WEC, the path toward regular participation in IMSA's major events becomes more viable from a budgetary point of view. John Doonan, president of IMSA, called the agreement a collective benefit for organisers, manufacturers, teams and fans. Ed Bennett, CEO of the same entity, stressed that the three parties kept their focus on cost control, relevance to manufacturers, and the creation of broad participation opportunities.

The compromise that sustains the category

The 2030 regulations can be read as a negotiation resolved through concessions on both sides. The LMH manufacturers lose all‑wheel drive and part of the design freedom they had under the current rules. The LMDh manufacturers gain the possibility of developing their own components that were previously forced to buy from third parties.

Ferrari obtained the guarantee it sought: it can continue to build the entire vehicle in‑house. Toyota and Peugeot retain the possibility of designing their own hybrid system. The three manufacturers that defended the technology as a justification for their investment in endurance keep room for innovation, albeit within a more bounded framework.

The price of this stability is the disappearance of one of the most significant differences of the current Hypercar era. From 2030 onward, all prototypes will share the same basic architecture, will be driven through the same axle, and will be balanced with the same tools. Diversity will be concentrated in the engines, certain components of the hybrid system, and the visual identity of each bodywork.
