Extensive Changes to Le Mans GTE-Pro BoP

The FIA and ACO have confirmed Balance of Performance changes to five of the six manufacturers in the GTE-Pro class ahead of this weekend’s 24 Hours of Le Mans.

Three manufacturers have been handed weight adjustments, while there are boost ratio changes across the board for the quartet of turbocharged cars.

The new-generation Aston Martin Vantage GTEs that ran almost five seconds off the pace at the Test Day have been granted a boost increase, with smaller increases given to the BMW M8 GTE and Ferrari 488 GTE.

The Ford GT faces a minor boost reduction but countered with a 13kg weight break, compared to a 13kg weight increase for the BMW.

Chevrolet’s Corvette C7.R, meanwhile, will be 10kg heavier at the start of Free Practice on Wednesday, although Sportscar365 understands that this number has been offset by the team running heavier cars at the test.

Fuel capacity adjustments have been made to the Aston Martin (+4 liters), BMW (-4 liters) and Ford (-2 liters) but the maximum stint length of 14 laps for all GTE-Pro cars still applies.

The fastest car from the pre-event test, the Porsche 911 RSR, has not been handed any changes.

The only BoP change in the GTE-Am category is a 2-liter fuel increase for the previous-generation Aston Martin Vantage GTE.

While extensive changes have already been made, the FIA and ACO reserve the right for additional adjustments throughout the race week, leading up to Saturday’s race start.

Post-qualifying BoP changes occurred in the last two years.
