The FIA WEC have released the BoP figures which will be in place for the Le Mans test on June 3. Due to the unique nature of the Circuit de la Sarthe, the Blue Riband French race is excluded from the automatic BoP system introduced into the FIA World Endurance Championship last year.
Weight and power adjustments have been made to all cars since the WEC season-opener at Spa earlier this month. The somewhat large differences can most likely be explained as an attempt to maintain the speed differentials, including on the straights, between the various classes in the race on June 16/17.
The new turbocharged Aston Martin Vantage AMR has been hit the least, suffering only a slight reduction in turbo boost and a 5kgs increase in minimum weight since Spa. The new BMW M8 GTE, which also appeared slow in Belgium, has been handed a further 13kgs of ballast and a slightly larger power reduction than the Aston. Both cars now weigh in at 1268kgs, compared to the Ford GT’s 1280kgs, after receiving a 25kgs increase and turbo boost reduction since Spa.
Ferrari’s 488 GTE EVO has been handed a similar power reduction to the Ford, although the Italian machine only gains 11kgs in weight.
Porsche’s 911 RSR starts with an air restrictor 0.6mm smaller than run at Spa and a 17kgs increase in weight. The Chevrolet Corvette C7.R, which does not compete in the WEC, will start with a largely unchanged BoP from last year, having been given a minimum weight of 1244kg, just 1kg more than in 2017, and the same 29.5mm engine air-restrictor.
Fuel capacities have also been adjusted to ensure the maximum stint length is 14 laps at Le Mans; per the bulletin, “teams cannot do more than 14 laps in any conditions”.
Looking at GTE-Am, the entrants will also face a class-wide reduction in power for Le Mans.
Both the older generation Aston Martin Vantage GTE and Porsche 911 RSR have been handed a 0.6mm reduction to their air restrictors, the Porsche gains 4kgs in weight and the non-EVO version of the Ferrari receives a slight boost decrease and a 4kg weight break following poor performance at Spa.
Remember also that the BoP can change between the official test on June 3rd and race week and again between qualifying and the start of the 24 Hours; remember the Ford ‘sandbagging’ scandal in 2016 with the sporting regulations also now allowing for penalties in the race to be given to manufacturers who have been deemed to be hiding their performance.
