Porsche has fitted the new 911 RSR with a new suspension and gearbox, with fenders, hoods, doors, underbody, wing, dashboard and center console all made from carbon fiber. Many body panels are made to pop out easily for a quick change in the pit lane. The battery is also lighter and the windows are made of plastic. All this helps improve the RSR’s weight balance and center of gravity. Motivation is provided by a 4.0-liter flat-six with 460 horsepower driving the rear wheels through a six-speed sequential gearbox. Two cars – wearing the numbers 91 and 92 – will contest Silverstone and Spa before tackling Le Mans in June.
