The 918 Spyder is driven by a unique type of plug-in hybrid system. It comprises a high-revving V8 engine with a displacement exceeding four litres and output of more than 368 kW (500 hp). The mid-engine power unit is based on the racing engine of the successful Porsche RS Spyder, which provided impressive proof of its efficiency with its multiple victories in the Michelin Green X Challenge in the American Le Mans Series, the Le Mans Series and the 24 Hours of Le Mans. Power transmission to the rear wheels is by means of a compact, seven gear Porsche-Doppelkupplungsgetriebe (PDK). This is complemented by two electric motors – one each on the front and rear axle – with a joint mechanical output of at least 160 kW (218 hp). This configuration offers an innovative, variable all-wheel drive with independent control of the propulsion force on both axles. The 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 25 km (16 miles) in the NEDC on purely electric power. The charging time depends on the country-specific mains network, being approximately three hours in Germany, for example. A quick charging option is planned to reduce charging time yet further.

The 918 Spyder’s combined total fuel consumption in the NEDC (ECE-R 101) is anticipated to be 3.0 l/100 km (94 mpg imp.), equating to CO2 emissions of 70 g/km (112 g/mile). Despite that, the super sports car offers performance of the highest order. It accelerates from a standing start to 100 km/h (62 mph) in a maximum of 3.2 seconds and has a top speed of more than 320 km/h (199 mph). That means the Spyder will be able to manage a lap of the Nürburgring Nordschleife in less than seven minutes and 30 seconds – trumping the Porsche Carrera GT, which needs seven minutes and 32 seconds. The top speed on purely electric power is 150 km/h (94 mph). To shorten the time the customer has to wait for the 918 Spyder, Porsche is offering everyone placing an order the exclusive opportunity to acquire a 911 Turbo S “Edition 918 Spyder”, also limited to no more than 918 units. Visually, both inside and out, the special edition is inspired by the 918 Spyder's characteristic individual features. That includes the distinctive acid green features such as the specific and part-embroidered model logos and seams, the instrument cluster needles, the specific PCM screen and illuminated door entry guards. The limited edition badge on the glove compartment lid 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 colour. Both the technology and basic equipment of the new 911 Turbo S “Edition 918 Spyder” are based on the 530 hp (295 kW) 911 Turbo S. In the case of the special edition, the already comprehensive standard equipment is complemented in particular by an enhanced leather interior, a special instrumentation version and additional carbon elements both inside and out. The 911 Turbo S “Edition 918 Spyder” is being offered to coincide with the commencement of sales of the 918 Spyder with deliveries starting in June 2011. The Coupé version of the special edition costs 173,241 Euro in Germany and 184,546 Euro as a Cabriolet – including VAT and country-specific equipment items respectively.
