Porsche has chosen the Volkswagen Auto Group “Group Night” on the eve of the 2013 Frankfurt Motor Show to pull the covers once and for all from its much-anticipated 918 Spyder.
The car boasts “the most powerful naturally aspirated engine in Porsche’s line up” according to the lengthy press release issued to attendees – excerpts of which are published below – but that’s not what people will be talking about.
The 2015 918 Spyder will be an e-hybrid, and represents the German powerhouse’s commitment to building fun-to-drive hybrids. It joins the Panamera in the ranks of electric boosted Porsches.
The highlights? 887 hp from the electric and V8 engines combined, as well as 944 ft-lb of torque make for impressive numbers, but if you want to be truly blown away, take a look at the fuel consumption figures. 3.3 L/100 km, from a 1,634 kg supercar capable of 0-100 in 2.8 seconds.
While it might not have supercar thirst, the 918 Spyder will have a supercar price tag, expected to be a shade under $850,000.
Press Release Excerpts:
A world first: A drive that harnesses the power of three separate power units
The main drive source is the 4.6-litre, eight-cylinder engine with an output of up to 608 bhp.
Based on the power unit of the successful RS Spyder endurance race car, the engine delivers engine speeds of up to 9,150 rpm and a power output per litre of approximately 132 bhp/litre – 26 bhp/litre more than that of the Carrera GT, making this the highest specific power of any naturally aspirated Porsche engine.
And it is not just the performance of the 918 Spyder engine that stirs up an emotive response: The sound of this vehicle is just as impressive, and can primarily be attributed to the “top pipes” – exhaust tailpipes that terminate directly above the engine in the upper part of the rear end. No other series production vehicle features this solution.
In parallel in the drivetrain: Hybrid module
The V8 engine is coupled to the hybrid module as the 918 Spyder is designed as a parallel hybrid like Porsche’s current hybrid models. The hybrid module essentially comprises a 115-kW electric motor and a decoupler that serves as the connection with the combustion engine.
Because of its parallel hybrid configuration, the 918 Spyder can be powered at the rear axle either individually by the combustion engine or the electric motor, or via bot drives together.
As is typical for a Porsche super sportscar, the power unit assembly in the 918 Spyder has been placed in front of the rear axle, and it does not have a direct mechanical connection to the front axle. A seven-speed Porsche Doppelkupplung (PDK) trans-mission handles power transmission to the rear axle.
Independent all-wheel drive: Front axle with electric motor
There is another independent electric motor that generates approximately 95 kW of power at the front axle. The front electric drive unit drives the wheels at a fixed gear ratio. A de-coupler decouples the electric motor at high speeds to prevent the motor from over-revving.
The drive torque is independently controlled for each axle, creating a very responsive allwheel drive function with significant potential in terms of traction and dynamic performance.
Porsche redefined: A new super sportscar for a new decade
The 918 Spyder continues a long tradition of super sportscars at Porsche. Many of these vehicles have set technological benchmarks and have become the ultimate sportscars of their decades: the Carrera GTS, the first Porsche Turbo, the 959, the 911 GT1 and the Carrera GT. More so than any of its predecessors, the 918 Spyder is providing the key momentum for developing technologies for future vehicle concepts.
The 918 Spyder features all the components that reflect the Porsche DNA in a format that is more powerful than ever before.
