With the concept study of a high-performance mid-engine sports car with highly efficient, low-emission drive to build the Dr. Ing hc F. Porsche AG, Stuttgart, and their hybrid skills further out. The prototype 918 Spyder combines racing high-tech and electrical mobility to a fascinating spectrum: On one hand small car emissions of 70 grams of CO2 per kilometer with three liters of fuel per 100 kilometers, the other driving performance of a super sports car with a speed of just under 3.2 seconds from zero to 100 km / h, a top speed of over 320 km / h and a lap on the Nürburgring Nordschleife, with less than 7:30 minutes is even better than the Porsche Carrera GT.

This vehicle is a prototype and can not be bought!

The innovative concept car Porsche 918 Spyder combines intelligent performance technology, as well as its high-tech motor racing classic, modern style at a great statement. The Porsche 918 Spyder with plug-in hybrid-drive allows the performance of a true super sports car with a fuel consumption of only three liters per 100 km in the NEDC. This corresponds to CO2 emissions of 70 g / km. The open two-seater is powered by a high-rev V8 engine with 500 hp and a maximum speed of 9.200/min and electrical machinery at the front and rear axle with a mechanical total output of 218 hp (160 kW). The V8 is a development of the successful 3.4-liter engine from the RS Spyder racing car and a mid-engine position placed in front of the rear axle.

This vehicle architecture guaranteed thanks to their good balance of high performance on the racetrack. As power transmission is a seven-speed dual-clutch gearbox Porsche, which is also on the strength of the electric drive started at the rear. The front electric motor drives the wheels via a fixed ratio.

As an energy storage lithium-ion battery is behind the passenger compartment. When a plug-in hybrid, the battery can be charged from the mains. Moreover, the kinetic energy of the vehicle during braking is converted into electrical energy and fed into the battery. To speed up operations so that additional energy is available. About a knob on the steering wheel, four different modes access: In the mode E-Drive is pure electric driving. with a range of up to 25 miles possible.

In the hybrid mode uses the 918 Spyder, both the E-machines as well as the internal combustion engine, with the use of individual drive components of the respective driving situation and can range from equal to consumption-benefit plans.

Even in the sports hybrid mode, both drive systems are used, but mainly performance-oriented control. The drive is rear-biased, a torque vectoring system also allows targeted improvement of driving dynamics. In the Race Hybrid mode, the drive systems are concentrated on a purely performance-oriented driving style driving dynamics with the highest demands on the circuit and operate at their limits.

With sufficient charge state allows a so-called push-to-pass button an additional electric power (E-Boost), for example to overtake, or for even better performance.

This large bandwidth of the hybrid drive allows it to reach the to 918 Spyder either lap times at the level of racing cars -or emit an economic driving only 70 grams of CO2 per kilometer. As with the drive motor racing genes even when lightweight body concept of the 918 Spyder to be determined. A modular structure with a monocoque carbon fiber reinforced plastics (CFRP) and the targeted use of magnesium and aluminum not only ensure the low weight of under 1490 kilograms, but also by high torsional rigidity for maximum driving precision.

The Porsche 918 Spyder typical design concept of the wake with his reference to the legendary and successful racing cars like the Porsche 917 Le Mans and the current Porsche RS Spyder emotions. The combination of car-typical proportions, a clearly structured design theme with perfectly prepared surfaces and innovative features resulting in an aesthetic, balanced design with great dynamics. It embodies the perfect synthesis of form and function of Posche design DNA.

The quiet balance between tradition and progress, provides formal adherence. A Porsche-typical, variable aerodynamic rear spoiler is in the field of vision as well as traditional accents. The distinctive scoops as extensions of the head restraints perform in the 918 Spyder is not only aerodynamic tasks, but also accommodate retractable air intake with ram-air function.

Driver and front passenger are embedded not only in a perfectly contoured sport bucket seats, but also in a cockpit, the synthesis of efficient function and ergonomic high-tech operation an outlook on possible future interior designs for super sports car can give. Three detached dials for speed (left), speed (middle) and energy (right) seem directly inspired by the racing cars of the 60s to be and embody the philosophy of the significant driver orientation.

In the 918 Spyder to pay the rising middle console a touch-sensitive surface (Touch Panel) for intuitive operation of the vehicle capabilities and commitment to consistent reduction of visible controls while maintaining a direct services. The driving-control elements are concentrated mainly in the three-spoke multifunction sports steering wheel. is the typical Porsche driving system variables are supplemented by a so-called Map-switch, which retrieve the different driving programs and serves more as a push-to-pass button for the E-Boost, for example when overtaking. The lighting of the instruments vary in shades of green and red for the consumption-modes performance-driving programs.

In addition, the 918 Spyder other innovative features such as the Range Manager. In the center of this display shows the activation of a map display of the navigation system with display of the residual range, which can be influenced by the driver on the road performance attitude. In cities with environmental zones, he indicates whether it can be achieved with the purely electric drive is a target in the city.

With this information, and the references to the drive-specific power stations, the individual driving and charging or fueling strategies are chosen. With the unique combination of extremely low maintenance, superior performance and high electric range of the 918 Spyder, a significant milestone in the strategy embodies Porsche to electric mobility.
