Balance of Performance for 24H Le Mans Revealed

The Balance of Performance table for the Hypercar class at next week’s 24 Hours of Le Mans has been revealed, featuring relatively minor changes compared to last year’s running of the FIA World Endurance Championship blue riband.

Revealed on Thursday ahead of this weekend’s official test day, the table shows virtually unchanged minimum weight values for all but one of the seven cars that raced at the Circuit de la Sarthe last year, albeit with more significant changes to base power.

The Le Mans BoP lies outside of the system used for the regular WEC rounds, meaning direct comparisons with last month’s Spa round are not applicable, with the values derived primarily from simulation rather than actual race data.

Ferrari, which heads into this year’s race searching for a third consecutive victory with its 499P, has a minimum weight of 1042 kg, down one kilogram from 2024, and a maximum power of 515kW below the Power Gain threshold of 250 km/h, up 7kW.

This is one of several notable increases in power across the class, with the Toyota GR010 Hybrid up by 12kW to the class maximum of 520kW, the Cadillac V.Series R up by 8kW to 517kW, and the Alpine A424 up by 10kW to 517kW.

Toyota maintains a minimum weight of 1053 kg, identical to last year, with the Cadillac and Alpine the only cars to receive increased weight, with both up by a single kilogram each to 1037 kg and 1039 kg respectively.

Like the Ferrari, the Porsche 963 is down one kilogram to 1041 kg, but its power output of 511kW is unchanged from last year’s race.

The major outlier on weight is the Peugeot 9X8, which has been brought down to 1039 kg from last year’s race, when it notably struggled for competitiveness, accompanied by a small base power reduction of 1kW to 507kW.

That makes it the least powerful in the class under the Power Gain threshold, followed by the BMW M Hybrid V8 on 510kW, that has an unchanged weight of 1039 kg.

However, the BMW is one of just two cars to be assigned a positive Power Gain value, along with the Porsche, with the BMW’s power rising to a class-high 520.2kW (+2.0 percent) above 250 km/h, with Porsche next up on 518.2kW (+1.4 percent).

Ferrari has the biggest drop above the threshold of 2.9 percent, equivalent to 14.9kW, making the 499P the least powerful car above 250 km/h, with the Peugeot, which falls by 1.2 percent, or 9.2kW, the second-least powerful.

Alpine sees a drop of 1.7 percent, Toyota of 1.3 percent and Cadillac of 0.8 percent.

Aston Martin’s brand-new Valkyrie has been assigned the class minimum weight of 1030 kg and the maximum power of 520kW for its Le Mans debut below 250km/h, with a Power Gain value of minus 0.8 percent.

Corvette, Ford Biggest Winners in LMGT3 BoP

In the BoP for the LMGT3 class, the biggest winners appear to be the Chevrolet Corvette Z06 GT3.R and the Ford Mustang GT3, both of which have been handed power increases and weight decreases compared to last year’s race.

While all seven of the cars in the class that raced last year will run with a lower minimum weight this time around, the Corvette and the Mustang are only two of three to have also been given an increase in power below 200 km/h.

The Corvette and Mustang are now both at P1 — meaning one percent below their theoretical maximum power — compared to P4 and P5 respectively last year.

However, the Corvette has a negative Power Gain value of 4.6 percent, versus minus two percent last year, while the Mustang is at zero.

At the same time, the Corvette now weighs in at 1333 kg, down 14 kg from last year’s race, while the Mustang tips the scales at 1318 kg, down 9 kg.

Only the Porsche 911 GT3 R, at 1315 kg, is lighter than the Mustang, but last year’s winning LMGT3 car has been given a reduction in base power to P4 from P3.

The only other car to have both gained power and lost weight is the Lexus RC F GT3, but its weight decrease is just a single kilogram, to 1354 kg, and while its power goes up two percent to P2, this is tempered by a minus 3.7 percent Power Gain.

Heaviest of all is the new-for-2025 Mercedes-AMG GT3 Evo at 1360 kg.
