The Porsche 918 Spyder is a mid-engined sports plug-in hybrid designed by Porsche and first shown as a concept at the 80th Geneva Motor Show in March 2010. The Spyder is powered by a 4.6 litre V8 engine, developing 608 horsepower (453 kW), with two electric motors delivering an additional 279 horsepower (208 kW) for a combined output of 887 horsepower (661 kW). It is the second plug-in hybrid car from Porsche, after the 2014 Panamera S E-Hybrid.[2] The production version was unveiled at the September 2013 Frankfurt Motor Show.[3]

The 918 Spyder is a limited edition supercar, and Porsche plans to manufacture 918 units as a 2014 model year. Production began on September 18, 2013, with deliveries scheduled to begin in December 2013.[4][5] The starting price is US$845,000.[6]

Porsche unveiled the RSR racing variant of the 918 at the 2011 North American International Auto Show, which combines hybrid technology first used in the 997 GT3 R Hybrid, with styling from the 918 Spyder.[7]

Specifications[edit]

The 918 Spyder is a mid-engined two-seater sports car designed by Michael Mauer.[8] It is powered by a 4.6 litre V8 engine. The engine is built on the same architecture as the one used in the RS Spyder Le Mans Prototype racing car without any engine belts.

The engine weights 140 kg according to Porsche and it delivers 608 horsepower (453 kW) at 8,500 rpm and 528 N·m (389 lbf·ft) of maximum torque.[6] This is supplemented by two electric motors delivering an additional 279 hp (208 kW).[9] One 154 hp (115 kW)[6] electric motor drives the rear wheels in parallel with the engine and also serves as the main generator.[9] This motor and engine deliver power to the rear axle via a 7-speed gearbox coupled to Porsche's own PDK double-clutch system. The front 125 hp (93 kW)[6] electric motor directly drives the front axle; an electric clutch decouples the motor when not in use.[9] The total system delivers 887 hp (661 kW) and 1,275 N·m (940 lbf·ft) of torque.[6] As of October 2012 the engineering design is not finalized,[9] but Porsche has given performance figures of 0–100 km/h (62 mph) in 2.6 seconds,[10] 0-200 km/h (120 mph) in 7.2 seconds, 300 kilometres per hour (190 mph) in 19.9 seconds and a top speed of approximately 345 kilometres per hour (214 mph).[6] The energy storage system is a 6.8 kW·h liquid-cooled lithium-ion battery positioned behind the passenger cell. In addition to plugging in to recharge, the batteries are also charged by regenerative braking and by excess output from the engine when the car is coasting. CO2 emissions are 79 g/km[2] and fuel consumption is 3.3 L/100 km (94 imperial mpg/78 us mpg).

The 918 Spyder offers five different running modes: E-Drive allows the car to run under battery power alone, using the rear electric motor and front motor, giving a range of 20 miles (32 km); the car can reach 93 mph (150 km/h) in this mode.[4] Three hybrid modes (Hybrid, Sport and Race) use both the engine and electric motors to provide the desired levels of economy and performance. In Race mode a push-to-pass button initiates the Hot Lap setting, which delivers additional electrical power.[11] The chassis is a carbon-fibre-reinforced plastic monocoque. Magnesium and aluminium are extensively used in the construction of the car which helps keep the 918 Spyder's weight down to 1,640 kilograms (3,600 lb).

On July 28, 2010, after 2000 declarations of interest, the Supervisory Board of Dr. Ing. h.c. F. Porsche AG, Stuttgart, gave the green light for series development of the 918 Spyder.[12]

Sales and production[edit]

The production version was unveiled at the 2013 Frankfurt Motor Show.[3] The 2014 model year 918 Spyder is being produced in a limited series and it was developed in Weissach and assembled in Zuffenhausen. Porsche planned to manufacture 918 units as a 2014 model year and production started on September 18, 2013, with deliveries scheduled to begin in December 2013.[4][5] Sales in the United States are slated for early 2014.[13] Pricing for the 918 Spyder will start at US$845,000 (~ €641,000 or GB£540,000).[6]

RSR[edit]

At the 2011 North American International Auto Show in Detroit, Porsche unveiled the RSR racing variant of the 918 Spyder. Instead of using plug-in hybrid technology, power for the two electric motors is provided by a flywheel accumulator KERS system that sits beside the driver in the passenger compartment. The V8 is a further development of the direct injection engine from the RS Spyder race car developing 563 horsepower (420 kW). The electric motors each provide an additional 102 horsepower (76 kW), giving a peak power output of 767 horsepower (572 kW). The six speed gearbox is a development of the unit from the RS Spyder.[7]

Record[edit]

Porsche announced that on September 4, 2013, a 918 fitted with the optional 'Weissach Package' set a Nürburgring lap time of 6:57 on the 12.8 mi (20.6 km) road course, reducing the previous record by 14 seconds, and making it the first series production street-legal automobile to break the 7 minute barrier.[13][14]

Video game appearances[edit]

The 918 Spyder is subject to numerous video games appearances, most notably in several games of the third generation of Need for Speed series. It was originally featured in the game Need for Speed: Hot Pursuit as a drivable vehicle.[15] Unlike the other Porsche cars featured in the game, it is not available in a police livery. It was later featured in Shift 2: Unleashed,[16] Need for Speed: The Run[17] (The Run only featured the RSR variant) and Need for Speed: Most Wanted (2012),[18] as well as in Real Racing 3. Most Wanted includes both the 918 Spyder's concept build on the in-game car roster and the 918 Spyder production model if the Terminal Velocity downloadable content is purchased.
