It was always unlikely that Porsche/Michelin’s qualifying lap of 3m16.887s at Le Mans last year would go unpunished by the discipline’s decision makers and the FIA Endurance Committee has effectively introduced measures to slow the hybrid LM P1s in 2016.
The energy allowance par lap at Le Mans has accordingly been cut by 10MJ which, says the FIA WEC press release, is a fall of around 7.5 percent. Fuel flow has been restricted by a similar proportion and the hybrid power has been cut to 300kW per lap at Le Mans.
For memory, the quantity of energy attributed to the Porsche 919 Hybrid/Michelin at Le Mans last June was 138MJ/lap, with a fuel flow of 88.5kg/h. The car’s rating was 8MJ which meant there were no restrictions regarding hybrid power.
Weight (870kg) and maximum turbo pressure (4 bar) are unchanged in LM P1, however.
Meanwhile, to keep a check on costs, only three aero kits will be allowed for the season and, testing time has been capped, as has wind tunnel work. Tyre quotas are the same for 2016, though.
The GTE’s BoP has been revised, too, with changes notably concerning the cars’ weights. The Porsche 911 RSR, Corvette C7.R and the Ferrari 488 will begin the season at 1,240kg, while the new Aston Martin Vantage and new Ford GT will tip the scales at 1,230kg and 1,260kg respectively for the 6 Hours of Silverstone.
At the same time, the diameter of the air restrictors of the Porsche 911 RSR (29.3mm), Corvette C7.R (29.8mm) and Aston Martin (30mm) is 0.7mm bigger compared with the end of 2015.
With regard to fuel tank sizes, the Aston Martin will start the year with a capacity of 95 litres, the Ford and Porsche with 90 litres, Corvette with 88 litres and the Ferrari 488 with 86 litres.
The FIA Endurance Committee is authorised to adjust these figures based on the average lap times of the fastest representative of each model over 20 percent of the race distance at the world championship’s opening rounds.
