This is what it might look like – the Porsche of tomorrow. Together with the new 911 Carrera, Porsche is presenting the “Mission E” concept car at the 2015 Frankfurt Motor Show.
The Porsche Mission E concept car is a coherent design of a sports car with an electric drive and all of the traits that make up a Porsche. In the Mission E, an entirely new spread is experienced between performance and efficiency – supplemented by a futuristic display and control concept.
The joint premiere with the new generation 911 Carrera has symbolic character. The first all-electrically powered four-seat Porsche of the 21st century represents the future of a concept that made the 911 the most successful sports car ever for over 50 years.
The Mission E concept car shows how Porsche envisions the future of the electric sports car. The fascinating design of the four-door car with four seats bears many references to the 911 while revealing the Mission E to be a Porsche at first glance. The passionately designed sports car with all-wheel drive develops a total power of over 600 hp, which can be converted into typical Porsche driving dynamics. The driving range of the Mission E is over 500 kilometres, and the innovative 800-volts battery charging system Porsche Turbo Charging reduces charging time to just slightly longer than it takes to fill a car’s fuel tank today. At the quick charge station, it takes just over fifteen minutes to provide enough charge for around 80 per cent of the total range. In keeping with the car’s purist interior, the control and display concept is intuitive with eye-tracking and gesture control as well as innovative functions.
Porsche Mission E: 600 hp, 500 km driving range, 15 minutes charging time
In presenting the Mission E at the IAA in Frankfurt, Porsche is introducing the first all-electrically powered four-seat sports car in the brand’s history. The concept car combines the unmistakable emotional design of a Porsche with excellent performance and the forward-thinking practicality of the first 800-volt drive system. Key specification data of this fascinating sports car: four doors and four single seats, over 600 hp (440 kW) system power and over 500 km driving range. All-wheel drive and all-wheel steering, zero to 100 km/h acceleration in under 3.5 seconds and a charging time of around 15 minutes to reach an 80 per cent charge of electrical energy. Instruments are intuitively operated by eye-tracking and gesture control, some even via holograms – highly oriented toward the driver by automatically adjusting the displays to the driver’s position.
The drive system of the Mission E is entirely new, yet it is typical Porsche, i.e. proven in motor racing. Two permanently-excited synchronous motors (PSM) – similar to those used in this year’s Le Mans victor, the 919 hybrid – accelerate the sports car and recover bra king energy. The best proof of a Porsche is 24 hours of top racing performance and a 1-2 finish.
Together the two motors produce over 600 hp, and they propel the Mission E to a speed of 100 km/h in less than 3.5 seconds and to 200 km/h in under twelve seconds. In addition to their high efficiency, power density and uniform power development, they offer another advantage: unlike today’s electric drive systems, they can develop their full power even after multiple accelerations at short intervals. The need-based all-wheel drive system with Porsche Torque Vectoring – which automatically distributes torque to the individual wheels – transfers the drive system’s power to the road, and all-wheel steering gives precise, sporty steering in the desired direction. This makes the Mission E fit for the circuit race track; its lap time on the North Loop of the Nürburgring is under the eight-minute mark.
It is not just passionate sportiness that makes up a Porsche but also a high level of every day practicality. Accordingly, the Mission E can travel over 500 km on one battery charge, and it can be charged with enough energy for around 400 km more driving range in less than fifteen minutes. The reason: Porsche is a front-runner in introducing innovative 800-volt technology for the first time. Doubling the voltage – compared to today’s electric vehicles that operate at 400 volts – offers multiple advantages: shorter charging times and lower weight, because lighter, smaller gage copper cables are sufficient for energy transport. A moveable body segment on the front left wing in front of the driver’s door gives access to the charging port for the innovative “Porsche Turbo Charging” system. Via the 800-volt port, the battery can be charged to approximately 80 per cent of its capacity in around 15 minutes – a record time for electric vehicles. As an alternative, the technology platform can be connected to a conventional 400-volt quick-charging station, or it can be replenished at home in the garage via convenient inductive charging by simply parking over a coil embedded in the floor of the garage from which the energy is transferred without cables to a coil on the car’s underbody.
Low centre of gravity for superior driving dynamics
Another feature that is typical of a Porsche sports car is a lightweight concept with optimal weight distribution and a low centre of gravity. The battery mounted in the car’s underbody, which is based on the latest lithium-ion technology, runs the whole length between the front and rear axles. This distributes its weight to the two drive axles uniformly, resulting in exceptionally good balance. In addition, it makes the sports car’s centre of gravity extremely low. Both of these factors significantly boost performance and a sports car feeling. The body as a whole is made up of a functional mix of aluminium, steel and carbon fibre reinforced polymer. The wheels are made of carbon: the Mission E has wide tyres mounted on 21-inch wheels in front and 22-inch wheels at the rear.
Design: fascinating sports car with Porsche DNA
Every square inch, every angle, every radius of the Mission E reflects one thing above all else: emotional sportiness in the best tradition of Porsche design The starting point is the sculpture of a sport saloon with a low height of 130 cm with sports car attributes from Zuffenhausen that embodies visible innovations such as its integrated aerodynamics. Distinc tive air inlets and outlets – on the front, sides and at the rear – typify the body’s full flow-through design that enhances efficiency and performance. Integrated air guides improve air flow around the wheels, for instance, and air outlets on the sides reduce overpressure in the wheel wells, thereby reducing lift.
The much reduced sculpting of the front end shows a classic Porsche sweepback, and it relates the concept car to the 918 Spyder and Porsche race cars. A new type of matrix LED headlights in the brand’s typical four-point light design captures the viewer’s gaze. Integrated as an element hovering in the airflow of the air inlet, they lend a futuristic character to the front end. The four LED units are grouped around a flat sensor for assistance systems whose border serves as an indicator light. Distinctive front wings and an extremely low-cut bonnet reference 911 design. As in the 911 GT3 RS, a wide characteristic recess extends from the overlapping front luggage compartment lid up and over the roof. The line of the side windows is also similar to that of the 911, however, with one important difference: two counter-opening doors enable convenient entry – without a B-pillar. Another difference: instead of the classic door mirror, inconspicuous cameras are mounted on the sides that con tribute to the car’s exceptional aerodynamics.
The rear design underscores the typical sports car architecture. The lean cabin with its accelerated rear windscreen, which draws inward at the rear, creates space for the sculpted shape of the rear wings that only a Porsche can have. A three-dimensional “PORSCHE” badge illuminated from inside hovers beneath an arch of light that extends across the entire width in a black glass element.
