The FIA World Endurance Championship has released 24 Hours of Le Mans BoP 2025 table – featuring fresh Balance of Performance adjustments for both Hypercar and LMGT3 classes ahead of official test day.
While the Balance of Performance methodology itself has undergone refinements for 2025 FIA WEC, Le Mans BoP is unique in that it is derived solely from simulation data, rather than from the rolling average of previous WEC races.
This approach is intended to prevent teams from “sandbagging” or manipulating their performance in the lead-up to the French endurance classic, ensuring that the BoP is based on the cars’ homologated specifications and theoretical capabilities.
In the Hypercar category, BoP changes for 2025 Le Mans 24 Hours are relatively minor compared to the previous year but carry significant implications for each manufacturer’s prospects.
The Ferrari 499P aiming for a third consecutive Le Mans victory sees its minimum weight reduced by one kilogram to 1042 kg and its maximum power increased by 7kW to 515kW below the Power Gain threshold of 250 km/h.
Meanwhile, the Toyota GR010 Hybrid retains its minimum weight at 1053 kg, unchanged from last year, but receives a notable boost in base power, up 12kW to the class maximum of 520kW.
Cadillac’s V-Series.R benefits from an 8kW increase bringing its base power to 517kW, coupled with a one-kilogram rise in minimum weight, now set at 1037 kg. Similarly, the Alpine A424 is granted a 10kW power increase to 517kW with its weight also rising by one kilogram to 1039 kg.

The Peugeot 9X8 stands out as the major outlier in Le Mans BoP 2025. After a challenging 2024 campaign, Peugeot’s minimum weight is reduced to 1039 kg – a significant drop from last year, but this is offset by a small decrease in base power now set at 507kW, down 1kW.
This makes the Peugeot the least powerful car in the class under the Power Gain threshold, a factor that could hinder its competitiveness unless the weight reduction delivers substantial handling and efficiency benefits.
The Porsche 963 gets one-kilogram reduction in weight to 1041 kg, while its power output remains unchanged at 511kW.
BMW’s M Hybrid V8 maintains its weight at 1039 kg with an unchanged base power of 510kW. However, BMW is one of only two manufacturers alongside Porsche to receive a positive Power Gain value above 250 km/h.
BMW’s power rises to a class-high 520.2kW – a 2.0 percent increase above the threshold – giving it a potential advantage in top speed, which is critical on the high-speed sections of Le Mans. Porsche follows closely with a 1.4 percent increase, reaching 518.2kW above 250 km/h.
Conversely, Ferrari experiences the largest drop in power above the 250 km/h threshold with a 2.9 percent reduction, equivalent to 14.9kW, making the 499P the least powerful car at high speeds.
Peugeot also sees a reduction down by 1.2 percent or 9.2kW, further compounding its challenges on the long straights.
These adjustments are indicative of the FIA World Endurance Championship’s intent to curb the top-end performance of certain cars to ensure a level playing field, particularly in the slipstream-heavy sections of the circuit.
Turning to the LMGT3 class, Le Mans BoP 2025 changes are equally significant with weight and power adjustments reflecting the diverse field of GT machinery.
The Chevrolet Corvette currently weighs 1333 kg, a substantial reduction of 14 kg from last year, which should translate into improved agility and reduced tyre degradation over long stints.
The Ford Mustang GT3 also benefits from a weight reduction, now tipping the scales at 1318 kg, down 9 kg. Last year’s LMGT3 winning Porsche 911 GT3 R is the lightest in class at 1315 kg but its base power has been reduced, potentially impacting its straight-line speed and acceleration.
The Lexus RC F GT3 is another notable case having both gained power and lost weight albeit by just one kilogram, now at 1354 kg. Its power increases by two percent but this is offset by a 3.7 percent reduction in Power Gain.
The Mercedes-AMG GT3 Evo enters 2025 Le Mans 24 Hours as the heaviest LMGT3 car at 1360 kg.
