Porsche 918 Spyder

In perhaps the biggest surprise at Geneva, Porsche pulled the covers off the stunning 2-seat 918 Spyder, a supercar that can get 78 mpg, says the Stuttgart company. Aided by a lightweight carbon chassis, the 3285-lb. 918 Concept hits 62 mph in less than 3.2 seconds, and has a top speed of 198 mph. A mid-mounted V-8 with more than 500 bhp is largely responsible for this, fortified by front and rear electric motors that add an extra 218 hp to the car’s propulsion. With a pure electric mode and even a rear-biased race mode, the 918, though only a concept, has real production possibilities. One recently lapped the Nürburgring track in Germany in less than 7 minutes 30 seconds, proving a hybrid sports car does indeed have a role in the company’s future
