The Porsche 918 Spyder is a high performance sports car manufactured by German marque Porsche.[5] The 918 Spyder is a plug-in hybrid powered by a mid-mounted naturally aspirated 4593 cc V8 engine, developing 447 kW at 8,700RPM, with two electric motors delivering an additional 210 kW for a combined output of 887 PS and 1280 Nm of torque.[6] The 918 Spyder's 6.8kWh lithium-ion battery pack delivers an all-electric range of 12 mi under the US Environmental Protection Agency's five-cycle tests.
Production began on 18 September 2013, with deliveries initially scheduled to begin in December 2013, and a starting price of ≈€781,000 (US$845,000 or £711,000).[7][8] The 918 Spyder was sold out in December 2014 and production ended in June 2015.
The 918 Spyder was first shown as a concept at the 80th Geneva Motor Show in March 2010. On 28 July 2010, after 2,000 declarations of interest, the supervisory board of Porsche AG approved series development of the 918 Spyder.[9] The production version was unveiled at the September 2013 Frankfurt Motor Show. Porsche also unveiled the RSR racing variant of the 918 at the 2011 North American International Auto Show, which combined hybrid technology first used in the 997 GT3 R Hybrid, with styling from the 918 Spyder.[10] However, the 918 RSR did not make it to production. The 918 Spyder was the second plug-in hybrid car manufactured by Porsche, after the 2014 Panamera S E-Hybrid.[11]
Set to be the replacement for the 918, the Porsche Mission X was presented first, at the preamble to the centenary of the 91st 24 Hours of Le Mans, in June of 2023 and to be produced in 2025.
Since its release, the Porsche 918 Spyder has been the subject of half a dozen different recalls, for issues ranging from both front and rear control arms breaking to seat belts.[12]
Specifications
The 918 Spyder is powered by a 4593 cc naturally aspirated V8 engine built on the same architecture as the one used in the RS Spyder[13] Le Mans Prototype racing car without any engine belts.
In developing the V8 for the 918 Spyder the bore remained 95 mm with the stroke increased from 59.9 mm (for 3397 cc) to 81 mm (for 4593 cc). The engine ran to 9,200 rpm. In 2011 an RSR version was introduced, which offered 563 bhp at 10,300 rpm.
The engine weighs 135 kg, according to Porsche, and delivers 447 kW at 8,700RPM and 540 Nm of maximum torque at 6,700RPM.[14] This is supplemented by two electric motors delivering an additional 210 kW. One 115 kW electric motor drives the rear wheels in parallel with the engine and also serves as the main generator. 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 95 kW electric motor directly drives the front axle; an electric clutch decouples the motor when not in use. The total system delivers 887 PS and 1280 Nm of torque.[14] Porsche provided official performance figures of 0–100 km/h in 2.6 seconds, 0–200 km/h in 7.2 seconds, 0–300 km/h in 19.9 seconds and a top speed of 345 km/h.[6]
Sales and production
The production version was unveiled at the 2013 Frankfurt Motor Show.[31] The 918 Spyder was produced in a limited series and it was developed in Weissach and assembled in Zuffenhausen for the 2014 model year. Production for the 2014 model year started on 18 September 2013, with deliveries scheduled to begin in December 2013.[32][7] Sales in the United States began in June 2014.[33] Pricing for the 918 Spyder started at €781,000 in Europe and US$845,000 in the U.S.[8] According to its battery size, the 918 Spyder was eligible to a federal tax credit of up to US$3,667.[34]
Weissach Package
The Weissach Package is a weight saving and aerodynamics package offered by Porsche for the 918 Spyder. It was an $84,000 factory option in the US. The package included magnesium wheels specially manufactured by BBS, an extended rear diffuser, and interior parts covered in Alcantara instead of leather. The windscreen frame, roof, rear wings, and rear-view mirrors were also made out of carbon fiber.[42]
Porsche 918 RSR
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 414 kW at 10,300RPM. The electric motors each provide an additional 150 kW, giving a peak power output of 564 kW. The six-speed gearbox is a development of the unit from the RS Spyder.[43]
Nürburgring lap time record
In September 2013 a 918 fitted with the optional 'Weissach Package' set a Nürburgring lap time of 6:57 on the 12.8 mi road course, reducing the previous record by 14 seconds, and making it the first street-legal production car to break the 7-minute barrier.[33][44]
