Ferrari Faces Performance Adjustments Ahead of Interlagos WEC Race

Strategic Adjustments for High Stakes Racing
Ferrari's Power Reduction and Weight Increase Explained
Ferrari's dominant 499P Le Mans Hypercar, which has maintained an undefeated streak in this year's World Endurance Championship, will undergo substantial performance adjustments for the upcoming Interlagos race. For the first time, the Italian manufacturer's vehicle will operate at its Hypercar minimum power output of 480kW (644bhp). This marks a notable decrease of 35kW (47bhp) since the recent Le Mans 24 Hours and 9kW (12bhp) compared to the Spa 6 Hours event in May. Additionally, the 499P will carry an extra 27kg of weight relative to Le Mans and 12kg more than at Spa. These changes are a direct consequence of the new WEC BoP system, which factors in race averages from the previous three non-Le Mans rounds, all of which Ferrari's AF Corse team won.
Comparative Performance Shifts from Previous Seasons
Comparing the 499P's current specifications to last year's Interlagos race reveals further disadvantages for Ferrari. The car will be 9kg heavier and have 23kW (30bhp) less power than in 2024, despite an increase in the power gain figure at speeds exceeding 250km/h (155mph) from 1.8% to 5.5%. Last year, both factory Ferrari cars finished in fifth and sixth positions, indicating a potential struggle with these new parameters. The FIA's BoP measures aim to create a more equitable racing environment across the Hypercar class, ensuring competitive parity among diverse prototypes.
BoP Adjustments for Rival Teams and Their Implications
The updated Balance of Performance also affects Ferrari's competitors, influencing their strategies for the Sao Paulo 6 Hours. Toyota's GR010 HYBRID LMH, a dominant force at Autodromo Jose Carlos Pace last year, will maintain its minimum weight of 1069kg but receive an additional 5kW (7bhp) of power. While the Toyota has gained 9kg in weight and lost 21kW (28bhp) since 2024, its power gain figure has significantly increased from 2.8% to 7.2%. Meanwhile, Porsche's 963 and Cadillac's V-Series LMDh entries will both see power increases of 7kW (9bhp) and 15kW (20bhp) respectively, alongside a 2kg reduction in minimum weight since Spa. BMW's M Hybrid V8 will receive a minor power boost of 2kW (3bhp) but incur a 9kg weight increase. Alpine's A424 LMDh, which recently secured its second podium at Spa, will lose 8kW (11bhp) of power and gain 8kg in weight. Peugeot's 9X8 2024 LMH returns to its pre-Le Mans BoP, operating at the minimum Hypercar weight of 1030kg and maximum power of 520kW (697bhp). The Aston Martin Valkyrie LMH will also align with the class minimum weight and maximum power settings. These extensive adjustments promise an exhilarating round five of the 2025 WEC season, with track activities commencing on Friday, July 11, at 11:00 local time.
