Porsche previews 600-hp Mission E electric conceptSep 14th, 2015
With the Mission E concept car that it just unveiled in Frankfurt, Porsche has introduced the first all-electrically powered four-seat sports car in the brand’s history. Is this a hint of the next Panamera?
The concept car combines the unmistakable design of a Porsche with excellent performance and the forward-thinking practicality of the first 800-volt drive system. It has four doors and four single seats, over 600 hp (440 kW) system power and over 500 km of 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. 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. Two permanent magnet synchronous motors (PMSM) – similar to those used in this year’s Le Mans victor, the 919 hybrid – accelerate the sports car and recover braking energy. 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 Nürburgring Nordschleife is under the eight-minute mark.
It is not just passionate sportiness that makes up a Porsche but also a high level of everyday practicality. Accordingly, the Mission E can travel over 500 km on one charge, and it can be charged with enough energy for around 400 km more driving range in about 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, which 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 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.
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. 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.
Every square inch, every angle, every radius of the Mission E reflects emotional sportiness in the best tradition of Porsche design. Distinctive 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 airflow 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 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.
The interior of the Mission E transfers all of the traditional Porsche design principles into the future: openness, pure design, clean architecture, driver orientation and everyday practicality. The all-electric drive concept made it possible to fully reinterpret the interior. The lack of a transmission tunnel, for instance, opens up space and gives a lighter and more airy atmosphere to the entire interior. Race bucket seats served as inspiration for the four single seats. Their lightweight design is weight-saving, and it gives occupants secure lateral support during dynamic driving. Between the front seats, the centre console – elegantly curved like a bridge with open space beneath it – extends up to the dashboard.
Inside, an innovative display and control concept opens up before the driver. It is intuitive, fast and free of distractions. The instrument cluster shows five round instruments – they can be recognized as Porsche, but they are displayed virtually in OLED technology. An eye-tracking system detects, via camera, which instrument the driver is viewing. The driver can then activate the menu of the instrument in focus by pushing a button on the steering wheel and navigate within it – which also involves an interplay of eye-tracking and manual activation. But that is not all: the display follows the seat position and body attitude of the driver in what is known as a parallax effect. If the driver sits lower, higher or leans to one side, the 3D display of the round instruments reacts and moves with the driver. This eliminates situations in which the steering wheel blocks the driver’s view of certain key information, for instance. All relevant information such as vehicle speed is always within the driver’s line of sight.
The Mission E can also be configured externally from a tablet via Porsche Car Connect. Using over-the-air and remote services the driver can essentially change the functional content of the vehicle overnight. A simple update via the integrated high-speed data module is all it takes to implement the travel guide or additional functions for the chassis, engine or infotainment system. The driver can use a smartphone or tablet to start updates conveniently from the Porsche Connect Store. Furthermore, Porsche Connect enables direct contact to a Porsche Centre for remote diagnostics or to schedule appointments. Another function of integrated Remote Services is the digital key, which can be sent via the Porsche Connect Portal. It not only lets the owner open the doors, but also other persons authorized by the owner such as friends or family. After successful authentication, the key can be used within a specific time frame and defined location.
The virtual exterior mirrors are literally eye-catching. The lower corners of the windscreen show the images of the outside cameras that are mounted in the front wings. The benefits: the driver gets a better view of images and the surroundings, and safety information can also be actively displayed there.
We love the Mission E, and we think its styling hints at what the Panamera might look like in the future. But if you love it as much as we do, why not drive a Panamera now?
