Porsche is the latest car company to go electric.

In presenting the Mission E at the IAA show in Frankfurt, Porsche introduced 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,” the company said in a press release.

Featuring four doors and four single seats, it comes in at over 600 hp system power and over 310 miles driving range. It incorporates all-wheel drive and all-wheel steering, 0-62 mph acceleration in less than 3.5 seconds and a charging time of around 15 minutes to reach an 80-percent 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.

Drive System

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.

In addition to their high efficiency, power density and uniform power development, the two motors offer another advantage: 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.

The car offers optimal weight distribution and a low center 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.

“The interior of the Mission E transfers all of the traditional Porsche design principles into the future: openness, purist design, clean architecture, driver orientation and everyday practicality,” the company adds.

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.

The dashboard also incorporates new ideas. Its division into two three-dimensionally structuring layers reinforces the impression of lightness and clarity. The upper layer integrates the driver’s display, and between the levels there is a holographic display that extends far into the passenger’s side.

It shows individually selectable apps, which are stacked in virtual space and arranged by priority with a three-dimensional effect. The driver or passenger can use these apps to touch-free control primary functions such as media, navigation, climate control, contacts and vehicle.

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.
