Porsche reveals updated 911 RSR for WEC and IMSA campaigns

Porsche has revealed a revised 911 RSR that will race next season in the GTE Pro class of the World Endurance Championship and in the 2020 IMSA SportsCar Championship

Porsche reveals updated 911 RSR for WEC and IMSA campaigns

The manufacturer revealed the new car, based on the latest 991.2 version of the road-going 911, at the Goodwood Festival of Speed on Saturday.

It replaces the 911 RSR that was introduced in 2017 and will make its race debut in the opening round of the '19/20 WEC season at Silverstone on September 1 after an extensive test programme that commenced last August.

Porsche GT motorsport boss Pascal Zurlinden said that "95% of the car is new" in relation to its predecessor, which sealed the 2018/19 WEC manufacturers' title with the help of victory in the Le Mans 24 Hours last year.

"Our engineers noticed room for improvement in a number of areas," Zurlinden added. "We have made significant progress in the development of our car for the next three-year homologation period, especially in the complex areas of driveability, efficiency, durability and serviceability.

"The only components that we've kept unchanged from the predecessor are the headlights, brake system, clutch, driver's seat and parts of the suspension."

Kevin Estre and Michael Christensen will defend their WEC title next season in the #92 911 RSR, while Gianmaria Bruni and Richard Lietz will once again team up in the sister #91 machine.

Porsche's CORE Autosport-operated IMSA squad, which currently leads the GT Le Mans class standings, will give the new car its US debut in next January's Daytona 24 Hours.

The existing car will race on in the WEC during the 2019/20 campaign in the GTE Am class before the new version is made available to customers the following season.

It's 50 years since Jo Siffert was killed in his prime at Brands Hatch. The Swiss scored just two world championship wins in a Formula 1 career spent largely with privateer teams, but showed on numerous occasions in single-seaters and in sportscars with Porsche that he could beat any of the best drivers of his era given the right equipment

Team WRT has been at the forefront of GT racing for years and made a successful move to prototypes for 2021, capped by an LMP2 win on its Le Mans debut. It could've been even better had the race been one lap shorter, when its cars ran 1-2, but the stranger-than-fiction reality has spurred the team to reach greater heights

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.
