Endurance classics such as the 24 Hours of Daytona, the 12 Hours of Sebring and Petit Le Mans make the IMSA WeatherTech SportsCar Championship one of the most attractive racing series in the world. This season’s calendar is made up of twelve rounds on the most demanding racetracks in the USA and Canada. For 2019, the Porsche GT Team again fields two 911 RSR in the GTLM class. In the GTD class, Porsche customer teams compete with the new 911 GT3 R with support from factory drivers.

Sharing the cockpit of the No. 911 Porsche 911 RSR are Frédéric Makowiecki (France) and Nick Tandy (Great Britain) . Matt Campbell joins them as the third driver for the endurance events at Daytona, Sebring, Watkins Glen and Petit Le Mans. In 2018, this trio won the rounds in Sebring and Braselton. The regular crew of the No. 912 sister car also remains unchanged. Earl Bamber (New Zealand) and Laurens Vanthoor (Belgium) will contest all rounds, with Mathieu Jaminet (France) supporting them at the endurance classics.

Porsche customer teams such as Park Place Motorsports and Pfaff Motorsports tackle the GTD class with the latest generation 911 GT3 R. Porsche works driver Patrick Long will contest the entire season. At the races over longer distances, works driver Dirk Werner (Germany) as well as both Porsche Young Professionals Matt Campbell (Australia) and Matteo Cairoli (Italy) will compete.

The races at Daytona, Sebring, Watkins Glen and Petit Le Mans count towards the prestigious North American Endurance Cup. In 2017, Porsche won the drivers’ and team titles in the toughest and most coveted category in terms of performance and reliability that exists globally in GT racing.

DPi (Daytona Prototype international): This is the class for prototypes complying with Dpi regulations.
