The 4WD electric Mission e is a concept car, but a production car very similar to it will be ready by 2019. As Porsche says "Compact electric motors, no combustion engine, no exhaust system, no transmission tunnel. Plenty of opportunities to question and rethink previous forms". Who has driven the Tesla Model S, understands that electric performance cars are something very special and Porsche is on the right path with their future family cars. Because of excessive mass, these cars cannot be called sports cars, though.
The system voltage is 800V, twice the common in 2015. With Porsche Turbo Charging, loading with 800V at DC charging stations is considerably faster than usual – 80% of the maximum charge level in less than 15 minutes. In other words: in approximately 4 minutes loading time the range increases by about 100 km. But the battery can also be charged at a conventional public charging station or at home: by charging cable via the charging port hidden at the side of the front fender.
As the Mission e doesn't have the tunnel for the drive shaft, the floor is made flat. This makes the body weaker, as well as does removing the B-pillars. But, Porsche can afford that, because they use carbon fibre monocoque, a first for a 4 passenger car. They call it ‘Weissach Frame’.
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 in 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 in-struments reacts and moves with the driver. This eliminates situations in which the steering wheel blocks the driver's view of certain key information.
The entire dashboard is chock full of 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 desired symbol is activated by gestures that are detected by sensors. A grasping gesture means select, while pulling means control. Moreover, driver or passenger can use a touch display on the centre console to control secondary functions such as detailed information menus.
The two permanently excited synchronous motors of the Mission E concept car have passed the test as a Motor Generator Unit (MGU) in the Porsche 919 racing car.
Green light was given for the project on December 4, 2015. The car will be built in Stuttgart.
