The race in GTD PRO was very intense with the top 3 ending within 5 sec. Matthieu Jaminet won the class with Pfaff Motorsport Porsche #9 co-driven by Matt Campbell and Felipe Nasr.

The race was very tight from start to finish as the top 4 finished within 5.615 sec., after having exchanged the lead in the closing hours and seeing all seven DPi cars on the lead during the first half of the race.

Many changes of leaders during the first half of the race with the 7 DPi’s within 5.5 sec. Currently #5 JDC Miller Motorsport Cadillac holds the lead thanks to less pits than competitors. In GTE PRO, 6 cars are within 6.6 sec.

Four time Indy car Champion Sebastien Bourdais dominated the session and was the only one to cover the lap in less than 1:35 with his #01 V-Performance Academy Cadillac.

Poor weather conditions for the Thursday sessions with a mostly wet track.

The second practice saw some dryer laps enabling the 2 WEC 2021 World Drivers Champions to perform the fastest laps with K. Kobayashi (#48 Ally Cadillac) in P1 and M. Conway (#31 Whelen Engineering Racing) in P2. 

Ricky Taylor, Filipe Albuquerque, Alexander Rossi and Will Stevens will start the 60th running of the 24 hours of Daytona from pole as Taylor and Albuquerque won the Rolex qualifying 100 minutes race this Sunday.
