Chronology
Predecessor Porsche Carrera GT[2]

The Porsche 918 Spyder is a mid-engined plug-in hybrid sports car manufactured by German automobile manufacturer Porsche.[3] The Spyder is powered by a naturally aspirated 4.6 L (4,593 cc) V8 engine, developing 608 PS (447 kW; 600 bhp) at 8500 rpm, with two electric motors delivering an additional 210 kW (286 PS; 282 bhp) for a combined output of 887 PS (652 kW; 875 bhp) and 1,280 N⋅m (944 lbf⋅ft) of torque.[4][5] The 918 Spyder's 6.8 kWh lithium-ion battery pack delivers an all-electric range of 19 km (12 mi) under the US Environmental Protection Agency's five-cycle tests.[1]

Production began on September 18, 2013, with deliveries initially scheduled to begin in December 2013, and a starting price of ~ €611,000 (US$845,000 or GB£511,000).[6][7][8] The 918 Spyder was sold out in December 2014 and production ended in June 2015.[9]

The 918 Spyder was first shown as a concept at the 80th Geneva Motor Show in March 2010.[6] On July 28, 2010, after 2,000 declarations of interest, the Supervisory board of Dr. Ing. h.c. F. Porsche AG, Stuttgart, approved series development of the 918 Spyder.[10] The production version was unveiled at the September 2013 Frankfurt Motor Show.[11] Porsche also 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.[12] The 918 Spyder was the second plug-in hybrid car from Porsche, after the 2014 Panamera S E-Hybrid.[13]

Specifications

Porsche 918 Spyder

The 918 Spyder is powered by a 4,593 cc (4.6 L; 280.3 cu in) naturally aspirated V8 engine built on the same architecture as the one used in the RS Spyder Le Mans Prototype racing car without any engine belts.

The engine weighs 135 kg (298 lb) according to Porsche and delivers 608 PS (600 hp; 447 kW) at 8,600 rpm and 530 N⋅m (391 lbf⋅ft) of maximum torque at 6,600 rpm.[14] This is supplemented by two electric motors delivering an additional 210 kW (286 PS; 282 hp). One 115 kW (156 PS; 154 hp) 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 (129 PS; 127 hp) electric motor directly drives the front axle; an electric clutch decouples the motor when not in use. The total system delivers 887 PS (652 kW; 875 bhp) and 1,280 N⋅m (944 lbf⋅ft) of torque.[5] By October 2012, the engineering design was not finalized, but Porsche provided performance figures of 0–100 km/h (0–62 mph) in 2.5 seconds, 0–200 km/h (0–124 mph) in 7.2 seconds, 0–300 km/h (0–186 mph) in 19.9 seconds and a tested top speed of 350 km/h (217 mph). The Porsche 918 Spyder has a power to weight ratio of 1.93 kg (4.25 lb) per horsepower, and the Weissach Package-equipped car has a power to weight ratio of 1.85 kg (4.08 lb) per horsepower.[4][8][15][16]

Porsche 918 Spyder Weissach Package

In Car and Driver's independent test of the Porsche 918, C/D achieved 0–60 mph (0–97 km/h) in 2.2 seconds, 0–100 mph (0–161 km/h) in 4.9 seconds, 0–180 mph (0–290 km/h) in 17.5 seconds, and the 1/4 mile in 9.8 seconds.[17][18] Motor Trend's independent test of the Porsche 918 claims that with a 2.4 seconds 0-60 mph (97 km/h) time it was the fastest car to 60 mph that they had ever tested. It stopped from 60 mph (97 km/h)-0 in 94 ft (29 m), and broke Motor Trend's figure 8 record at 22.2 seconds.[19] European magazine tests yielded 7.0 seconds for 0–200 km/h (0–124 mph) and 17.75 seconds for the standing kilometer reaching 295.9 km/h (184 mph).[20][21]

The energy storage system is a 312-cell, liquid-cooled 6.8 kW·h lithium-ion battery positioned behind the passenger cell. In addition to a plug-in charge port at the passenger-side B pillar, 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 and fuel consumption is 3 L/100 km (94 mpg‑imp; 78 mpg‑US) under the New European Driving Cycle (NEDC).[13][22] The U.S. Environmental Protection Agency (EPA) under its five-cycle tests rated the 2015 model year Porsche 918 Spyder energy consumption in all-electric mode at 50 kWh per 100 miles, which translates into a combined city/highway fuel economy of 3.5 L/100 km (81 mpg‑imp; 67 mpg‑US). When powered only by the gasoline engine, EPA's official combined city/highway fuel economy is 22 mpg‑US (11 L/100 km; 26 mpg‑imp).[1]

The 918 Spyder utilises the same 4.6L V8 engine as in the Porsche RS Spyder

The 4.6 litre V8 petrol engine can recharge an empty battery on about two litres of fuel.[23] The supplied Porsche Universal Charger requires seven hours to charge the battery on a typical 110 volt household AC socket or two hours on a dedicated Charging Dock installed with a 240 volt industrial supply. An optional DC Speed Charging Station can restore the battery to full capacity in 25 minutes.[24]

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 18 miles (29 km) for the concept model.[24] The official U.S. EPA all-electric range is 12 mi (19 km). The total range with a full tank of gasoline and a fully charged battery is 420 miles (680 km) according to EPA tests.[1] Under the E-Drive mode the car can reach 93 mph (150 km/h).[6] Two hybrid modes (Hybrid, 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.[25] The chassis is a carbon-fibre-reinforced plastic monocoque and the brakes used are electromechanical brakes.[26]

Sales and production

The production version was unveiled at the 2013 Frankfurt Motor Show.[11] The 2014 model year 918 Spyder was produced in a limited series and it was developed in Weissach and assembled in Zuffenhausen. Porsche manufactured 918 units as a 2014 model year and production started on November 18, 2013, with deliveries scheduled to begin in December 2013.[6][7] Sales in the United States began in June 2014.[27] Pricing for the 918 Spyder started at US$845,000 (~ €611,000 or GB£511,000).[8] According to its battery size, the 918 Spyder was eligible to a federal tax credit of up to US$3,667.[28]

As of November 2014, over 800 units had been ordered worldwide, with planned production sold out through late March or early April 2015. Production ended in June 2015 as scheduled.[9]

The country with the most orders is the United States with 294 units, followed by China and Germany with approximately 100 orders each, and Canada ordering 35 units.[29][30][31]

According to JATO Dynamics, a total of 105 units have been registered worldwide during the first nine months of 2014.[32] The United States is the leading market with 202 units delivered up to May 2015.[33] As of October 2014, a total of 9 units were registered in Switzerland, 6 in the Netherlands, 5 units in Canada, 4 in Sweden, 3 in Brazil and 1 in South Africa.[34][35][33][36]

In 2014 recalls were issued for five cars to replace rear-axle control arms and 39 cars to replace front lower control arms. Another recall was made for some cars in 2015 to secure a wiring harness to prevent it from chafing.[37][38]

RSR

The 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 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.[12]

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 20.6 km (12.8 mi) road course, reducing the previous record by 14 seconds, and making it the first series production street-legal car to break the 7-minute barrier.[27][39]
