Porsche 918 RSR 2011

The latest offering from Porsche was formally unveiled at the 2011 North American International Auto Show in Detroit, Michigan. The Porsche 918 RSR is a mid-engine concept car available as part of a limited production series.

The concept car is the first official plug-in hybrid automobile from Porsche. It was first shown at the Geneva Motor Show in March of 2010. Known internally as Project XG10, the Porsche 918 RSR reaches 60 mph from a dead stop in less than 3.2 seconds and is capable of reaching over 200 miles per hour.

Although the bulk of the charge comes from energy via the plug-in socket, the batteries also builds up a charge through regenerative braking and any excess power output from the engine when the vehicle is coasting.

The Porsche 918 RSR uses a hybrid battery system rather than a traditional flywheel to allow significantly more power to be stored. The system allows the sport car to drive up to 15 miles before the engine kicks in.

The two door roadster packs a 3.4 litre V8 engine and a 7-speed PDK dual clutch transmission. The sport car has a lightweight carbon-fibre reinforced plastic single shell and a frame made almost exclusively from magnesium and aluminium.

The display car shown in Detroit has a well laid-out, closed cockpit with a jet black interior. It had bold orange stripes on top of a dazzling silver paint job. It also bore the number 22 – a tribute to the winning Porsche 917 K that obliterated the competition in Le Mans 40 years ago.
