Two Porsche 911 RSR cars* on Friday will race more than 1,000 miles at round six of the Sports Car World Endurance Championship (aka WEC), with another two identical Porsche models on Saturday undertaking the twelve-hour IMSA WeatherTech Sports  Car Championship at the so-called Super Sebring race this weekend. It requires a massive effort from Porsche in terms of personnel and logistics – comparable to Porsche’s largest ever GT run at Le Mans in 2018. BMW is currently first after Daytona.
