Balance of Performance revealed for Le Mans 24 Hours
Here's how all the LMH๊ and LMDh cars will be balanced🌺 at the 2025 Le Mans 24 Hours.

A number of Hypercar manufacturers have received a 🎃notable boost in power ahead of this month’s Le Mans 24 Hours, following the release of the updated ꦚBalance of Performance by the FIA and the ACO.
New entrant💯 Aston Martin and WEC stalwart Toyota have both been allowed to run their Le Mans Hypercars at 520kW below 250km/h 𝕴— the maximum permitted under the regulations.
For Toyota, this marks a 12kW increase compared to last year, when its GR010༒ Hybrid finished second and fꦐifth in the French endurance classic.
Defending Le Mans winner Ferrari has been handed a 4kW power increase, raising the 499P’s output from 508kW to𒀰 512kW🐲.
BMW’s M Hybrid V8 has received a 2kW bump to 510kW, ꦰwhile both the Alpine A424 and ⛦Cadillac V-Series.R have been brought up to 517kW.
There is no change for the Porsche 963, which retains its 511kW output. Peugeot, meanwhile, has been🦩 hit with a minor 1kW reduction, dropping its base power to 517🔯kW.
Above 250km/h, ❀stage-two powꦯer adjustments have also been applied. BMW will benefit from a 2% power increase beyond this threshold, with Porsche receiving a 1.4% gain.
All other manufact🦂urers have been given reductions in stage two, with Ferrari receiving the largest hit — a 2.9% cut in power above 250km/h.
Adjustments have also been made to minimum weight requirements in the Hypercar class. Alpine and Cadillac will carry an extra kilogram compared to 2024, while Ferrari and Porsche☂ have been given a 1kg break each.
Peugeot’s 9X𒁏8 has been given an 8kg reduction, bringing its weight down from 1047kg to🥂 1039kg.
Toyota’s minimum weight remains unchanged, but at 1053kg, the GR010 ꦺHybrid continues to be the heaviest car in the Hypercar field.
