Porsche has released official photos of a prototype of its new 918 Spyder supercar undergoing driving trials. The 2014 Porsche 918 Spyder, which will be delivered to U.S. buyers in late 2013, features a paint design that is reminiscent of the historical Porsche 917 race cars. The supercar is a plug-in hybrid that uses a high-performance combustion engine and two electric motors to produce 770 hp and can get up to 78 mpg. The body and chassis are constructed primarily from carbon fiber and features fully-adaptive aerodynamics and adaptive, rear-axle steering. Porsche has been taking orders for the car since last year, which is priced at $845,000.

In other Porsche news, company CEO Matthias Mueller recently told the German newspaper Stuttgarter Zeitung that it has no plans to build a smaller sedan based on its Porsche Panamera, though it might consider such a model in five or six years. Last week, TCS News reported the German car magazine Auto Bild reported such a plan was in the works for 2017 at the latest.
