Porsche Endurance Challenge North America Launched

New USAC-sanctioned Porsche one-make championship to debut at Circuit of The Americas in May…

Porsche Motorsport North America has launched the Porsche Endurance Challenge North America series, a four-event championship featuring Porsche 911 GT3 Cup and 718 Cayman GT4 RS Clubsport machinery.

The USAC-sanctioned series will kick off at Circuit of The Americas in late May with a 60-minute race, followed by events at Road America and Sonoma Raceway before returning to Austin for a six-hour season finale in November.

Both the Type 991.2 and current-generation Type-922 Porsche 911 GT3 Cup race car will be eligible, alongside the GT4-spec Porsche in separate classes, with the series set to utilize regulations from Porsche Sprint Challenge North America by Yokohama.

The first three rounds, all 60 minutes in length, will mandate a single pit stop. Regulations for the six-hour endurance round, with its added drivers and consumables, will require a minimum of four stops for fuel.

The three opening rounds will allow a single driver format with a maximum of two drivers per car, with one of the drivers holding no more than a Bronze rating. The six-hour finale will require three drivers, and allow up to two drivers with a Bronze rating.

Further technical details and regulations for the series will be announced at a later date.

“The Porsche Motorsport Pyramid North America is designed to bridge the gaps through the ranks of racing in the United States and Canada,” said Porsche Motorsport North America President and CEO Volker Holzmeyer. “The Porsche Endurance Challenge North America will take this further.

“The series is designed to provide our one-make drivers – particularly those who don’t make racing their livelihood – and teams an endurance racing alternative with cars they know well: the Porsche 911 GT3 Cup and Porsche 718 Cayman GT4 RS Clubsport.

“We have focused on cost efficient ways to go endurance racing and, as all cars are the same, a very equal competition between the drivers participating. Initial interest has been very positive, and we look forward to our first event in Austin at the end of May.”
