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. On March 21, 2011 Porsche started taking orders. 918 will be 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 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.
Basically, this comprises an electro-mechanical adjustment system on both rear wheels. The adjustment is speed-sensitive and executes steering angles of a few degrees in each direction. 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.
Engine and top exhaust pipes
In contrary to the 2010 concept car where the exhaust pipes exited in the sides, the tailpipes of the production model will 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 requires 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. The 4.6V8 can rev up to 9,150 rpm.
With this package the weight is added by additional aerodynamic body parts and 6-point harnesses, but reduced thanks to magnesium wheels and less sound isolation. The wheels measure 9.5x20" in front with 265/35 tyres and 12.5x21" at the rear with 325/30 tyres. The package shaves off 35 kg/77 lb (from 1675 kg/3692 lb to 1640 kg/3615 lb). The roof, rear wings, mirrors and frames of the windscreen are made of visible carbon. Parts of the interior are upholstered with Alcantara instead of leather, and visible carbon replaces much of the aluminium. Optionally available is film-coating instead of body paint. The package costs about 10% on top of the car price, which means you could get another Porsche for it.
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 approximately 7 kWh. The 100 kg / 220 lbs 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 10A power socket on the 230V 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.
A button on the steering wheel allows the driver to choose among five different running modes.
E-Power modeFor running the car under electric power alone, with a range of about 25 km / 16 miles. When the vehicle is started up, this mode is the default operating mode as long as the battery is sufficiently charged. This mode only drives the front wheels, making 918 the first front-wheel-drive Porsche (fortunately only in E-Power mode). Top speed in electric mode is 150 km/h / 93 mph. When the charge state of the battery falls below a set minimum value, the vehicle automatically switches to hybrid mode.
Hybrid modeUses both the electric motors and the V8. At the speeds over 235 kmh/146 mph the front drive is decoupled.
Sport Hybrid modeThe V8 is now in constant operation and provides the main propulsive force. Most of the drive power goes to the rear wheels, with Torque Vectoring serving to additionally improve the car’s driving dynamics.
Race Hybrid modeMeant for race track use, the drive systems are focused on pure performance. The combustion engine charges the battery when the driver is not utilising the maximum output. With the battery sufficiently charged, the push-to-pass button can be used to exploit the full power of the car, for example when overtaking or for just the maximum acceleration. In contrast to Sport Hybrid mode the electric motors run at their maximum power output limits.
Race Hybrid Hot Lap modeThe “Hot Lap” button in the middle of the map switch releases the last reserves and can only be activated in “Race Hybrid” mode. Similar to a qualification mode, this pushes the battery to its maximum power output limits for a few fast laps. This mode uses all of the available energy in the battery.
The following photos and videos show the concept car with side exhaust pipes and camera mirrors.
2012 March 26: Rolling chassis
2012 May 15: First road-legal prototype and optional Salzburg livery
2012 July 5: optional Martini livery unweiled
2012 July 18 (or earlier) test drive on Nürburgring
2012 September 18: optional Psychedelic livery
2012 September 18: Nürburgring Nordschleife lap time of 7:14 achieved by Marc Lieb
918 was initially designed to be able to lap Nordschleife in 7:22. Considering its heavy weight, it would be a good result, but as Porsche already had a faster car, the 911 997 GT2 RS with it's 7:18 lap record, the Weissach engineers had to push the 918 further. With the optional Weissach racing package, the car was able to lap Nordschleife on September 18, 2012 in only 7:14. This of course with the street legal Michelin tyres. And this time even from the standing start!
2013 May 14: journalists get to drive the near production ready version
With the May 16, 2013 press release the power was raised: for the 4.6V8 from 426 to 449 kW, front electric motor from 80 to 95 kW, rear electric motor from 90 to 115 kW, combined power up from 585 to 652 kW, torque up from 750 Nm/551lb-ft to 800 Nm/588 lb-ft. Acceleration 0-100 kmh is down from 2.9 to 2.8 seconds, 0-200 km down from 8.9 to 7.9 seconds, 0-300 kmh down from 26.9 to 23 seconds. Top speed is up from 326 kmh/203 mph to 340 kmh/211 mph. Nice!
