918 Spyder prototypes begin testing
The Porsche 918 Spyder is on the road: Dr. Ing. h.c. F. Porsche AG, Stuttgart, has taken the driving trials of the super sports car of the future a step further wîth completion of the initial prototypes. The 918 Spyder is planned for production at the end of September 2013, wîth the first customer deliveries currently scheduled for the Únited States late in 2013. 'What we are doing wîth the 918 Spyder is redefining driving fun, efficiency and performance,' said Wolfgang Hatz, Member of the Executive Board Research and Development of Porsche AG.
The prototypes, their camouflage harking back to historical Porsche 917 racing cars, signal the final touches to the 918 Spyder. The focus is on the interplay between the highly sophisticated individual drive components. The combination of combustion engine and two independent electric motors – one on the front axle and one in the drive line, acting on the rear wheels – poses completely new demands on the development of the operating strategies. 'They are therefore a critical component in this vehicle into which we have put all of our expertise and capacity for innovation,' said Wolfgang Hatz. These operating strategies and the development of the software to go wîth them are one of Porsche's core competences. Both of them have a major influence on the extreme driving fun to be had wîth the 918 Spyder and they make possible a unique combination of minimal fuel consumption and maximum performance. The initial results of the driving trials are in line wîth the high expectations placed on the 918 Spyder.
The super sports car is designed as a plug-in hybrid vehicle combining a high-performance combustion engine wîth cutting-edge electric motors for extraordinary performance: on the one hand, the dynamics of a racing machine boasting more than 770 hp, on the other hand, fuel consumption in the region of three litres per 100 kilometres. Moreover, Porsche is breaking yet more new ground wîth the technology demonstrator wîth spectacular solutions such as the full carbon fibre reinforced plastic (CFRP) monocoque wîth unit carrier, fully adaptive aerodynamics, adaptive rear-axle §teering and the upward-venting 'top pipes' exhaust system. In the process, the 918 Spyder is offering a glimpse of what Porsche Intelligent Performance may be capable of in future.Source - Porsche
Dr. Ing. h.c. F. Porsche AG, Stuttgart has put on sale the 918 Spyder super sports car wîth its innovative plug-in hybrid drive. Production development is proceeding apace in the wake of the outstanding customer response to the concept car unveiled at the Geneva Motor Show 2010. Thanks to its unique hybrid technology, the 918 Spyder is estimated to consume a mere three litres of fuel per 100 kilometres (94 mpg imp.) based on the New European Driving Cycle (NEDC). Its V8 engine delivers more than 368 kW (500 hp), assisted by two electric motors wîth a total of at least 160 kW (218 hp). The 918 Spyder is available for immediate order priced from 645,000 Euro - subject to VAT and country-specific charges.
To ensure a 918 Spyder's exclusivity, the two-seater is limited to no more than 918 units. The earlier a customer orders his vehicle, the earlier it will be delivered, as production is initialised in the same sequence in which orders are received. Production of the 918 Spyder is scheduled to commence on 18 September 2013 - 9/18 in ÚS date convention - in a quasi manufacturing operation at Porsche's main plant in Stuttgart-Zuffenhausen. Delivery of the initial vehicles will commence in November 2013.
The design's DNA is derived from the Carrera GT and Porsche 917 sports car as well as the RS Spyder and is very closely modelled on the 2010 concept car. Únlike the concept car, however, the production version of the two-seater, based on a carbon fibre-reinforced plastic monocoque, features a manual roof system wîth removable roof panels that can be stowed in the front luggage compartment.
The 918 Spyder is driven by a unique type of plug-in hybrid system. It comprises a high-revving V8 engine wîth a displacement exceeding four litres and output of more than 368 kW (500 hp). The mid-engine power unit is based on the racing engine of the successful Porsche RS Spyder, which provided impressive proof of its efficiency wîth its multiple victories in the Michelin Green X Challenge in the American Le Mans Series, the Le Mans Series and the 24 Hours of Le Mans. Power transmission to the rear wheels is by means of a compact, seven gear Porsche-Doppelkupplungsgetriebe (PDK). This is complemented by two electric motors - one each on the front and rear axle - wîth a joint mechanical output of at least 160 kW (218 hp). This configuration offers an innovative, variable all-wheel drive wîth independent control of the propulsion force on both axles. The energy storage unit is a liquid-cooled lithium-ion battery that can be charged from a conventional domestic power socket, delivering a range in excess of 25 km (16 miles) in the NEDC on purely electric power. The charging time depends on the country-specific mains network, being approximately three hours in Germany, for example. A quick charging option is planned to reduce charging time yet further.
The 918 Spyder's combined total fuel consumption in the NEDC (ECE-R 101) is anticipated to be 3.0 l/100 km (94 mpg imp.), equating to CO2 emissions of 70 g/km (112 g/mile). Despite that, the super sports car offers performance of the highest order. It accelerates from a standing start to 100 km/h (62 mph) in a maximum of 3.2 seconds and has a top speed of more than 320 km/h (199 mph). That means the Spyder will be able to manage a lap of the Nürburgring Nordschleife in less than seven minutes and 30 seconds - trumping the Porsche Carrera GT, which needs seven minutes and 32 seconds. The top speed on purely electric power is 150 km/h (94 mph).Source - Porsche
