to a single LMP2 vehicle. The DragonSpeed, Iron Lynx and Team Project 1 teams each had one car added to the entry list while the D'Station Racing Aston Martin Vantage GTE and the Inter Europol Competition Ligier JS P217 cars were deleted from the reserve list. In August, WeatherTech Racing moved its Ferrari 488 GTE Evo from the LMGTE Am to the LMGTE Pro category following a driver lineup change. Carlin's Dallara P217 and Kessel Racing's LMGTE Am Ferrari withdrew later that month as Iron Lynx added a third Ferrari to the LMGTE Am class. On 11 September, the remaining Team LNT Ginetta G60-LT-P1 entry withdrew because of uncertainties related to UK COVID-19 quarantine measures, and its effect on Ginetta's business model. This reduced the entry list to 59 cars. Testing For the first time since the race, the ACO did not hold an official test day for teams to test car aerodynamic updates at Le Mans. The ACO cancelled it because of the compression of international motor racing calendar schedules, and did not want to strain participants by holding too many events, like the test day, close to each other. Thus, drivers who had not entered the event within the preceding five years were required to drive at least ten laps during the first two practice sessions and attend a simulator test. Pre-race balance of performance changes The FIA Endurance Committee imposed an equivalence of technology in LMP1 and LMP2 and a balance of performance in an attempt to create parity between LMGTE Pro and LMGTE Am. A total of of ballast was added to the Toyota TS050 Hybrid compared to 2019 to reduce its handling, while non-hybrid and turbocharged LMP1 privateers had no change in weight. Privateers were allowed to use 11 laps worth of fuel per stint to fall in line with Toyota and larger refuelling restrictor diameters for quicker refuelling by one second. In LMGTE Pro, the Aston Martin Vantage GTE received an increased turbocharger boost from 2019 and more fuel capacity for better performance. The Porsche 911 RSR-19 was given a increase in ballast and a larger air restrictor from its predecessor. The LMGTE Am Aston Martin, Ferrari and Porsches had an increase of in weight for tighter handling. Practice The first three-hour practice session occurred on the morning of 17 September. Nakajima set the fastest lap of 3 minutes, 21.656 seconds in the 8
