Larger than its predecessor, and with a lower centre of gravity and better weight distribution, the 991 RSR utilizes carbon fibre for its front and rear wheel arch extensions, doors, underbody, rear wing, and quick-release front lid and rear panel. The material was also used to construct the dashboard and centre console. Other weight-saving measures include the use of polycarbonate for the windows and a lithium-ion battery.
The same 338 kW/460 hp 4.0-litre unit that saw service in last year’s 911 GT3 RSR has been retained for the 991, with gears in the six-speed transmission being changed via flappy paddles on the steering wheel.
Other features include a new wishbone front suspension set-up, which replaces the previously used McPherson struts, while deep cooling air intakes at the front of the car feed the brakes and centrally-mounted radiator.
Set to compete at this year’s 24 Hours of Le Mans and in the World Endurance Championship, two cars will be fielded in the GTE category by Porsche AG Team Manthey, with Olaf Manthey in the role of team manager.
Porsche works drivers Richard Lietz and Patrick Pilet shared driving duties at the Florida circuit. Lietz will take part in the WEC as well as Le Mans with Marc Lieb in car number 92, while Pilet joins forces with Joerg Bergmeister in the number 91 vehicle. It will celebrate its race début on April 14 at the WEC season-opener in Silverstone.
