Porsche has officially unveiled the 918 Spyder after months of teasers and prototypes. Billed as Porsche’s challenger to the McLaren P1 and Ferrari LaFerrari, the 918 Spyder is unique in that it pairs a traditional, mid-mounted 4.6 liter V8 engine with a trio of electric motors for a combined power output of 887 horsepower. With the engine and electric motors running in sync, the 918 will do 0-62 mph in 2.8 seconds before topping out at a respectable 186 mph. While it certainly won’t live up to the performance of its two main competitors, with a price tag starting at $845,000 USD compared to the estimated seven-figure price tags of the LaFerrari and P1, it’s a reasonable trade-off. The 918 Spyder is set to go on sale in limited numbers starting in 2014.
