DEBUT: 2011 Detroit Auto Show
APPEARANCE: The Porsche 918 RSR is a two-seat, mid-engined coupé which combines technology from the 911 GT3 R Hybrid and the design of the 918 Spyder concept. Like the Spyder, it is built from lightweight carbonfibre reinforced plastic. The most notable differences in the design are the race-bred tweaks with its air intake on the roof and doors which open upwards. Other exterior bodywork additions include a front lip spoiler, front spats and 19-inch centre-lock wheels.
The interior is another area that has been inspired by the Spyder with leather and bare aluminium although unlike the Spyders it is much more minimilastic and looks much more like a production interior rather than concept. The start number 22 on the show car pays tribute to a 917 short-tail coupé that won the 1971 Le Mans 24 Hours by Helmut Marko and Gijs van Lennep.
PREDICTION: Porsche has stayed true to this concept car’s racing pedigree and the car uses a flywheel energy recovery system and is powered by a race spec V8 engine and two electric motors on the front wheels. Porsche are likely to race the car in the future and speculation is rife that the car will also result in a production model for the road. Hints that this car is more production ready than the 918 Spyder include the realistic interior and the addition of gearshift lights.
