Porsche 918
The 918 Spyder at the IAA 2013 in Frankfurt
Under the type designation of the Porsche 918 sports car manufacturer Porsche has so far presented two different vehicle concepts, both of which are designed as a high-performance mid-engined vehicles with hybrid drive.
The 918 Spyder is a two-door two-seat sports car and a roadster body. He was introduced on 1 March 2010 at the Geneva Motor Show, the launch is scheduled for November 2013. The basic price will be 768 026 EUR.
The 918 RSR is an application based on the study of a Spyder race car with components of the drive technology of the Porsche 997 GT3 R Hybrid. The RSR was presented in January 2011 at the Detroit North American International Auto Show. About a production or a race for the vehicle has not yet decided.
For the design Michael Mauer was responsible. The former Porsche development chief Wolfgang Dürheimer has been awarded for the car from the car magazine Top Gear as Man of the Year 2010.
918 Spyder
First, the 918 Spyder was just a concept car, but a series production the Supervisory Board approved on 28 July 2010.
The 918 Spyder is powered by a V8 engine with a displacement of 4.6 liters, 450 kW ( 608 hp), which is based on the 3.4-liter engine of the Porsche RS Spyder, as well as electric motors on the front and rear axle afford the additional 210 kW.
The 918 Spyder has an electric four-wheel drive with " torque vectoring ". Up to a distance of 25 kilometers, the vehicle may solely on electric power. Also, since the 5.1 - kWh battery can be charged as a plug -in hybrid externally and this energy (theoretically about half a liter of gasoline equivalent) is not included in the European standard usage, the vehicle reaches a theoretical consumption of 3, 0 liters of gasoline per 100 kilometers, which corresponds to CO2 emissions of 70 g equivalent / km.
The power is transmitted via a dual clutch transmission. A regenerative braking transfers the energy to a nearly 100 -pound lithium -ion battery, which is located between the fuel tank and engine. The body is constructed as a modular structure with a monocoque made of CFRP.
On September 18, 2012, the 918 Spyder drove a Porsche - record time of 7:14 minutes on the Nürburgring- Nordschleife. The overall project management for the Weissach-developed in the Porsche Development Center 918 Spyder Frank -Steffen Walliser. On September 4, 2013 Marc Lieb improved the lap record of the 918 Spyder on the Nürburgring- Nordschleife in 6:57 minutes; Thus, 17 seconds faster than the existing record of vehicles produced in series with road-legal tires. Manufacturing is the 918 Spyder, Porsche 's main plant in Zuffenhausen.
Specifications
918 RSR
At the Detroit Motor Show 2011 Porsche introduced a mid-engined coupe with the design of the 918 Spyder and the flywheel from the already proven successful Porsche 997 GT3 R Hybrid before that obtains its additional power from its own vehicle dynamics when braking.
The study of the Porsche 918 RSR now has two electric motors on the front wheels with 75 kW, a maximum output of 544 kW ( 767 hp). The additional power gained during braking is conserved in a flywheel energy storage and accessed by the driver pressing a button.
In contrast to the 918 Spyder concept prevails in the interior of the 918 RSR now unadorned racing atmosphere. Instead of a center console with touch-sensitive user interface consistent from the 918 Spyder concept car, the new study has a stripped-down console with rocker switches. Instead of a second seat is there, the flywheel accumulator placed.
The presence on the RSR race number 22 is a throwback to the Porsche 917K of Martini Racing Team, winning car of the 24- hour race at Le Mans in 1971, which was driven by Helmut Marko and Gijs van Lennep and with 5335.313 km a distance record aufstellte, who had also due in 1972 and 1990, the changes made at the Circuit des 24 Heures, by 2010 inventory.
