The sports car manufacturer Porsche has so far presented two different vehicle concepts under the type designation Porsche 918 , both of which are designed as high-performance, mid-engine vehicles with hybrid drives .
The 918 Spyder is a two-door, two-seater super sports car with a roadster body. It was presented at the Geneva Motor Show on March 1, 2010 ; the market launch was in November 2013. The basic price was 768,026 euros, for weight-optimized vehicles with the Weissach package it was 839,426 euros. Production of the model, limited to 918 copies, was discontinued on June 19, 2015. However, the 918 Spyder will continue to serve as a driving force behind technical developments. The main focus will be on the further development of the drive concept, consisting of two electric motors and a combustion engine.
The 918 RSR is a study based on the Spyder of a racing car with drive technology components from the Porsche 997 GT3 R Hybrid . The RSR was unveiled at the Detroit North American International Auto Show in January 2011 . A final decision has not yet been made about production or racing of the vehicle.
Michael Mauer was responsible for the design . The then head of development at Porsche, Wolfgang Dürheimer , was named Man of the Year 2010 for the car by the Top Gear car magazine .
918 Spyder
Initially, the 918 Spyder was only a concept vehicle , but the Supervisory Board approved series production on July 28, 2010.
The 918 Spyder is powered by a 4.6 liter V8 engine with 447 kW (608 hp), which is based on the 3.4 liter engine of the Porsche RS Spyder , and an electric motor on the front axle of 95 kW ( 129 PS) and one on the rear axle 115 kW (156 PS). The total output of the engines is 652 kW (887 hp).
The 918 Spyder has electric four-wheel drive with torque vectoring . The vehicle can drive purely electrically up to a range of 25 kilometers. Since the 6.8 kWh battery can also be charged externally as a plug-in hybrid and this energy (theoretically equivalent to about half a liter of petrol) is not taken into account in the European standard consumption, the vehicle achieves a theoretical consumption of 3.0 liters of petrol per 100 kilometers, corresponding to a CO 2 / km corresponds to emissions of 70 g.
The power is transmitted via a dual clutch transmission (PDK). A braking energy recovery system transfers the energy to a lithium-ion battery weighing almost 100 kg , which is located between the tank and the motor. The body is designed 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. Frank-Steffen Walliser is in charge of the overall project management for the 918 Spyder developed at the Porsche development center in Weissach . On September 4th, 2013 Marc Lieb improved the lap record of the 918 Spyder on the Nürburgring-Nordschleife to 6:57 minutes; thus 17 seconds faster than the existing record of the series-produced vehicles with road-legal tires. The 918 Spyder was manufactured in the main Porsche factory in Zuffenhausen .

Trivia
" In order to adequately shorten the waiting time until your personal 918 Spyder is ready " (quote from Porsche), an exclusive special model of the 911 Turbo S (type 997) Edition 918 Spyder was offered as a coupe or convertible, which was limited to 918 copies worldwide. The contrasting color acid green , which is used on the 918 Spyder, was used for the brake calipers, the undersides of the exterior mirrors and the type designation on the rear. The air inlets for the intercoolers are made of carbon fiber, the 19 "RS Spyder rims were painted black. Upon customer request, this turbo could be ordered in the color of the 918 Spyder ordered.
In addition, Porsche offered a handcrafted resin model, also limited to 918 copies, made up of more than 165 individual parts in a 1: 8 scale. The price was 4,500.00 euros for a standard model in a showcase . A way to personal also was for 8,000.00 euros motor vehicle registration individualized model available in which, as in a real vehicle, the buyer the paint, the interior, and a plaque was able to determine the individual number of the model.
In 2014, the book trilogy “Porsche 918 Spyder” was published by Delius Klasing Verlag in collaboration with Stefan Bogner , Jürgen Pander and Klaus-Achim Peitzmeier . The trilogy includes the “Picture Book”, “Fact Book” and the “Story Book”, in which images, facts and stories are presented.
918 RSR
At the Detroit Motor Show 2011, Porsche presented a mid-engine coupé with the design of the 918 Spyder and the flywheel accumulator from the already successfully tested Porsche 997 GT3 R Hybrid, which derives its additional braking power from its own driving dynamics.
The study of the Porsche 918 RSR now has two electric motors on the front wheels, each with 75 kW and thus a maximum output of 544 kW (767 hp). The additional power gained during braking is transferred to a flywheel mass memory and called up by the driver at the push of a button.
In contrast to the 918 Spyder concept study, the interior of the 918 RSR now has a simple racing atmosphere. Instead of a center console with a completely touch-sensitive user interface from the 918 Spyder concept study, the new study has a console with toggle switches that has been reduced to the essentials. The flywheel accumulator is located there instead of a second seat.
The start number 22 on the RSR is a reminiscence of the Porsche 917 K of the Martini Racing Team , the winning car of the 24-hour race of Le Mans in 1971 , which was driven by Helmut Marko and Gijs van Lennep and with a total of 5335.313 km A distance record that lasted until 2010 , also because of the renovations carried out on the Circuit des 24 Heures in 1972 and 1990 .
