Porsche will actually put in production the 918 Spyder plug-in hybrid. It will be produced in a limited run starting in 2013, but the company has already started to take orders for the car.  The vehicle will be produced in September 2013 on a limited series at Stuttgart-Zuffenhausen plant in Germany. Porsche 918 Spyder is powered by a unique type of plug-in hybrid system. It includes a high-revving 4.0 liter V8 engine and 500HP.

The design of the Porsche 918 Spyder is derived from the Carrera GT and Porsche 917 race car as well as the 918 RSR concept and 918 Spyder concept. Unlike the concept car, however, the production version, based on a carbon fibre-reinforced plastic monocoque, features a manual roof system with removable roof panels that can be stowed in the front luggage compartment.
The electrical energy storage unit is a liquid-cooled lithium-ion battery that can be charged from a conventional domestic power socket, delivering a range in excess of 16 miles (25km) on purely electric power. The charging time depends on the country-specific mains network, being approximately three hours from a 230v domestic power supply, for example. A quick charging option is planned to reduce charging time yet further. 
Both the technology and standard equipment of the new 911 Turbo S ‘Edition 918 Spyder’ are based on the 530 hp 911 Turbo S. Visually, both inside and out, this model is inspired by the characteristic individual features of the 918 Spyder. This includes distinctive acid green features such as part-embroidered model logos and upholstery seams, the instrument dial needles, unique PCM screen and illuminated door entry guards as well as an enhanced leather interior and additional carbon elements both inside and out. The badge on the glovebox bears the same number as the 918 Spyder the customer has ordered. The 911 Turbo S ‘Edition 918 Spyder’ can also be ordered in the same color the customer has chosen for their 918 Spyder.
