Porsche unveiled the 918 Spyder Concept at the 2010 Geneva Motor Show, followed by the 918 RSR Racing Lab at the 2011 Detroit Auto Show. Both concepts will be used as base versions for the 918 Spyder production and racing vehicles scheduled to arrive in 2013.
The production version 918 Spyder was officially confirmed for an end of 2013 launch with the first deliveries beginning in early 2014. Porsche will build only 918 units and will price each unit at $845,000 on the US market.
The Porsche 918 Spyder Concept is powered by a 500 HP 3.4 liter V8, along with a pair of electric motors producing 109 horsepower each. But for the production version, this engine will be replaced with an engine featuring a larger displacement of 4.6 liter based on the RS Spyder LMP2 race car. This engine will deliver a total of 550 HP and will be combined with three electric motors that will increase the total output to an impressive 720 HP.
