The work of 100 Weissach technicians, who developed the 918 Spyder concept car, received deserved honour on July 28, 2010, when the supervisory board of Porsche AG decided to develop the concept car into series production car. 8 pilot vehicles for testing different components aswell as 25 prototypes were made. Michael Drolshagen was appointed as the director of the 918 production. On March 21, 2011 Porsche started taking orders and on September 18, 2013 making of the first production 918 started. 918 was produced at the Porsche's main factory in Stuttgart (for comparison, the Carrera GT was produced in Leipzig, with only the engine made in Stuttgart). The last, 918th, order was taken in November 2014 for the car to be finished by the middle of 2015. Of the 918 cars 297 were ordered for USA. Buyers both in Germany and in China ordered around 100 cars.

Body

The Spyder's body is fully made of carbon fibre reinforced plastic (CFRP) and has a two-piece Targa roof. The car has a 43/57 weight distribution.

Rear-axle steering

Basically, this comprises an electro-mechanical adjustment system on both rear wheels. The adjustment is speed-sensitive and executes steering angles up to 3 degrees in both directions. At low speeds, the system steers the rear wheels in the opposite direction to the front wheels - this makes cornering easier and reduces the turning circle. At higher speeds, the system steers the rear wheels in the same direction as the front wheels and the car virtually changes lanes sideways. It is more complicated when power sliding as then the ground speed is not high, but the rear wheels should steer at the same direction with the front wheels.

Petrol engine and top exhaust pipes

In contrary to the 2010 concept car where the exhaust pipes exited in the sides, the pipes of the production model exit just above the engine. The top pipes’ greatest benefit is that the hot exhaust gases are evacuated as quickly as possible and the exhaust gas back pressure remains low. This design required a new, thermodynamic air channelling concept: the exhaust manifolds are located inside in the cylinder V and the intake tracts are outside. There’s a further benefit: the engine compartment remains cooler. Just that when filling the car at the gas station, extra care has to be taken into account as the fuel filler neck is not too far from the hot exhaust pipes.

Weissach package

With this package the weight was added by rear side fins and 6-point harnesses, but reduced thanks to many features, including:
• magnesium wheels (minus 14.9 kg/32.8 lb). The wheels were in the same sizes as the ones on the standard car: 9.5x20" in front with 265/35 tyres and 12.5x21" at the rear with 325/30 tyres.
• film-coating instead of body paint (minus 2.3 kg/5 lb)
• lighter brake system (minus 2.0 kg/4.4 lb)
• titanium chassis bolts (minus 0.8 kg/1.7 lb)
• ceramic wheel bearings (minus 0.7 kg/1.5 lb)
• less sound isolation
• deleted Speed Charging onboard equipment
• deleted automatic function for AC
• deleted Burmester sound system
In total the package shaved off up to 41 kg/90 lb (from 1675 kg/3692 lb to 1634 kg/3602 lb). Parts of the interior were upholstered with Alcantara instead of leather, and visible CFRP replaced much of the aluminium. The frame of the windscreen, roof, mirror housings and rear wing were also of visible carbon fibre reinforced plastic. The Weissach package costed about 10% on top of the car price, which meant you could get another Porsche for it.

Weight

With the concept car the announced target weight for the production car was under 1490 kg /3285 lb. This was not achieved. It was the same with the Carrera GT - the target weight was 1250 kg, but the finished car weighed 1380 kg. The engine capacity was increased in order to keep up with the higher weight. With the 918 the initial weight target was 1490 kg and the V8 had 3.4-litre capacity. The production car weighed at least 1634 kg and the new 4.6-litre engine was needed.

Electricity

The 918 Spyder can brake using both electric motors and thus recuperate energy for the battery. The electric energy is stored by a liquid-cooled lithium-ion battery comprising 312 individual cells with an energy content of 6.8 kWh. The 140 kg / 308 lb battery provides best performance at temperatures 20-40°C / 68-104°F.
The plug-in interface enables the battery to be connected directly with the home mains supply. For example, the battery can be charged within 4 hours from a 10 A power socket on the 230 V mains supply. A compact charging station is also supplied with the car. This can be installed permanently in the garage. It permits rapid and convenient charging within approximately 2 hours. The battery is covered with 7-year warranty. The power steering and air conditioning system are both run on electric motors. There is no need for the strong 12V battery, so it is a 20 Ah lightweight lithium-ion unit.
