Porsche Mission E concept

   Porsche recently introduced the brand's first ever all electric four seater sports car at the Frankfrut IAA.

   This Car combines the unmistakable emotional design of Porsche with excellent performance. As stated earlier the key specification data are four single seats,four doors,over 600horsepower(440kW) system power and over 500km of driving range from its 800volt drive system. 0-100 takes merely 3.5 seconds and a 15min charging to reach an 80% charge of driving energy. Instruments are intuitively controlled by eye tracking and gestures,even some by holograms.

Drive system

   The drive system of Mission E is entirely new but traditionally Porsche i.e proven in motor racing. Two permanent magnet synchronous motors (PMSM),same of those used in this year's LeMans victor,the 919hybrid. The best proof of Porsche is 24hours of top racing performance and a 1-2finish. 

   The two motors together produce over 600hp, and take Mission E to 100kmph in 3.5seconds and to 200kmph in under 12seconds. In addition to these high efficiency and high power density they offer another advantage,unlike today's electric drive they can develop full power even after multiple accelerations at short intervals. The all wheel drive system with Porsche Torque Vectoring system automatically distributes torque to all four wheels,and  all wheel steering gives precise ,sporty steering in the desired direction. It makes it perfect for the circuit race track and its lap time on Nürbugring Nordschleife is under eight minutes. 

Drive Range

The Mission E can travel over 500km on a single charge and can be charged for 400km in about 15mins. The reason is,Porsche is a front runner in introducing innovative 800-volt technology for the first time. Doubling the voltage also offers multiple advantages like shorter charging times and lower weights, because lighter,smaller gage copper cables are sufficient for energy transport. 

A movable body segment on the front left wing in front of the driver's door gives excess to the charging port of the "Porsche turbo charging" system. Via the 800volt port the car can be charged to 80% in about 15minutes and that is a record time for electric vehicles. As an alternative it can also be connected to conventional 400-volt charging station,or it can be replenished at home in the garage by conventional inductive charging by parking over a coil embedded in the floor of garage from which the energy is transferred without cable to a coil on cars underbody. 

Driving dynamics 

Another typical Porsche feature is a lightweight concept with a lower centre and optimal weight distribution. The battery mounted on the vehicle runs through out the body between the two axels. This distributes its weight uniformly on both the axels,resulting in exceptionally good balance. In addition to this it makes the sports car's centre of gravity low. Both of these factors significantly increase performance and sports car feeling. 

The body as whole is made from a mix of aluminium,steel and carbon reinforced polymer. The wheels are made of carbon. Mission E has 21inch wide wheels mounted on the front and 22inch wide wheels mounted on the rear. 

Design 

Every square inch,every angle,every radius of Mission E reflects one thing above all else that is emotional sportiness in the best tradition of Porsche design. A sport saloon with a low height of 130cm with sports car attributes from Zuffenhausen that embodies visible innovations. 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 air flow around the wheels and air outlets on the sides reduce over pressure in the wheel wells there by reducing air lift. 

A new type of matrix LED headlights in the brand's typical four point light design captures the viewers gaze. 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 contribute to the car's exceptional aerodynamics.

The interior of Mission E has all the traditional Porsche design principles of the future. Openness,purist design,clean architecture,driver orientation and everyday practicality. The all electric drive concept made it possible to fully reinterpret the interior. The lack of transmission tunnel,for instance adds up more space and gives it lighter and more airy atmosphere to the interior. Race bucket seats served as four single seats. The lightweight design is weight saving and it gives occupants secure lateral support during driving dynamic. Between the front seats,the centre console-elegantly curved like a bridge with open space extendeds upto the dashboard. 

Display and control concept 

The instrument cluster shows five round instruments-they can be recognised as Porsche,but they are displayed virtually in OLED technology,i.e by organic light emitting diodes. The round instruments are organized according to the driver-relevant themes of connected car,Performance,Drive,Energy and Sport Chrono. 

An eye tracking system detects via camera which instrument 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 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 even portray driving fun: a camera mounted in the rear-view mirror recognizes the driver's good mood and shows it as an emoticon in the round instrument. The fun factor can be saved together with individual information such as the route or speed, and it can be shared with friends via a social media link.
