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 con- cept 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 ener- gy. 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.
Drive system: over 600 hp with technologies from endurance racing
The drive system of the Mission E is entirely new, yet it is typical Porsche, i.e. proven in motor racing. 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. 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 Vector- ing – which automatically distributes torque to the individual wheels – transfers the
drive system’s power to the road, and all-wheel steering gives precise, sporty steer- ing 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.
Everyday practicality: convenient and quick charging, over 500 km driving range
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 bat- tery charge, and it can be charged with enough energy for around 400 km more driv- ing range in about fifteen minutes.
The reason: Porsche is a front-runner in introduc- ing 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 ca- bles 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.
