2020 24 Hours of Daytona
The 2020 24 Hours of Daytona was an endurance sports car race sanctioned by the International Motor Sports Association. The event was held at the Daytona International Speedway combined road course in Daytona Beach, Florida, on January 25–26, 2020. This event was the 58th running of the 24 Hours of Daytona, and the first of 12 races across multiple classes in the 2020 WeatherTech SportsCar Championship, as well as the first of four rounds in the 2020 Michelin Endurance Cup.
Background
Regulation changes
Prior to the start of the 2020 WeatherTech SportsCar Championship, a series of regulation changes were made, including changes to driver eligibility for the secondary prototype class in the series, the Le Mans Prototype class. The rule change stated that each LMP2 team is only allowed to enter one Platinum-rated driver across the entire season, and it must be for the opening round at Daytona, due to the 24-hour-length of this round. A requirement for a Bronze-rated driver for the full season was also passed for the LMP2 class, in addition to the removal of the 24 Hours of Daytona as a points-scoring event for the class, instead only being a round for Michelin Endurance Cup Points.Change of leadership
Four months prior to the event, on September 19, 2019, Scott Atherton announced retirement from his position as the President of the International Motor Sports Association at the end of 2019. He had held that role since the merger of IMSA's American Le Mans Series with the Grand-Am Rolex Sports Car Series in 2014. One month following that announcement, then-director of Mazda's motorsports program in North America, John Doonan, was confirmed to be Atherton's replacement.Balance of Performance
On December 20, 2019, IMSA published a technical bulletin regarding the Balance of Performance constraints for the 24 hour event, as well as announcing a revised process for adjusting said constraints from race to race. The constraints were exclusive to the 24 Hours of Daytona and its test session, the Roar Before The 24. In the Daytona Prototype International class, the Cadillac DPi-V.R was made 20 kilograms heavier, bringing the car's weight to 950 kilograms. The Cadillac was also given 3.0 liter increase in fuel capacity. The Mazda RT24-P was given a five kilogram weight increase, bringing the total weight to 910 kilograms, 40 kilograms lighter than the Cadillac. By comparison, the Acura ARX-05 merely saw a 2.0 liter increase in fuel capacity.Roar Before the 24

Ten minutes later, the #55 Team Joest Mazda was the first DPi car to pit, and eventually the rest of the DPi's would follow. At the same time, the battle for the lead in GTLM was closely contested between the #3 Corvette C8.R and the #912 and #911 Porsche cars, which sat in first and third at the time, respectively. The BMW M8 GTE's of Team RLL were in fourth and fifth, trailing the #911 Porsche by twelve seconds. The GTLM's would begin their first pit stop cycle 52 minutes in, with no position changes after the stop sequence ended.
Hour 2
Four minutes into the second hour, Felipe Nasr in the #31 Cadillac was attempting to take the overall lead from the #77 Mazda of Oliver Jarvis. Soon enough, the second cycle of pit stops would start with the duo of Mazda prototypes, about forty minutes into both their stints. Just under thirty minutes into the second hour, the Corvette #3 now found itself in fourth place, dropping behind both the #912 Porsche and #25 BMW. However, trouble would be in store in the pits for the #25, with a slow stop that came from a problem with the removal of the left front wheel, costing them an extra minute in the pits. The #31 Cadillac would also have an unscheduled pit stop, using the stop to unclog the top roof intake. Their issue placed the #77 Mazda thirty seconds clear of the #6 Acura.

Later in the hour, the #10 would set the fastest race lap up to this point of 1:34.6.
