2015 Frankfurt Motor Show: Porsche showcases the Mission E concept
Porsche has showcased the Mission E concept, which could possibly be the direction that the company is heading towards in future. It is the first all-electric four-seat Porsche that has ever been developed by the brand and will use an 800V drive system that makes 600PS of power. Porsche claims that the Mission E can hit a 100kmph from standstill in under 3.5 seconds, and also that it has a driving range of 500km. It will get an all-wheel drive system that activates when needed and also an all-wheel steering system similar to the one on the Porsche 918.
The 800V drive system on the Mission E uses two permanently-excited synchronous motors (PSM) similar to the ones used on the Porsche 919 Hybrid that won Le Mans this year. The concept will also feature a brake energy recovery system seen in most hybrids these days. Porsche also says that it will hit 200kmph in less than 12 seconds. Porsche claims that the Mission E has clocked a lap time of less than eight minutes around the North Loop of the Nürburgring. Another impressive feat that Porsche claims is that the Mission E can be charged to 80 per cent in just 15 minutes using the Porsche Turbo Charging system. The charging port is located under a moveable body panel located on the front left wing. A secondary mode of charging the battery is through inductive charging, wherein the owner needs to park the car over a coil embedded in the floor of the garage, which transfers energy without the use of cables.
On the inside, the instrument clusters are naturally operated by eye-tracking and gesture control, with some of them being holograms. The four light-weight single seats were designed using race bucket seats as a base. The instrument panel displays five round instruments through an OLED display unit. The information in these instruments varies depending on which of the six driving modes - Connected Car, Performance, Drive, Energy and Sport Chrono - has been chosen. The Mission E does not have ORVMs. Instead it uses cameras on either side of the car that display the surroundings at the corners of the windscreen.
The eye-tracking system is a rather innovative concept that Porsche has introduced in the Mission E. It uses a camera to track the driver's eye movement and figure out which instrument he/she is focusing on. By pushing a button on the steering wheel, that particular instrument can be navigated on the screen, again, via eye-tracking. And if this isn't enough, the 3D display adjusts the information according to the driver's seat position and body structure, in what is known as a parallax effect.
The dashboard gets a 3D display unit that stretches all the way to the passenger side. Through this display, the driver or passenger can select apps to control applications like media, navigation and climate control, touch-free. The touch-display on the centre console can be used to pull up any other menus or information.
The Porsche Mission E can be configured and programmed externally through a tablet using Porsche Car Connect. The driver can use Over the Air and Remote Services to update services and change the functional content overnight. Porsche Connect can also be used to connect with a Porsche centre to schedule appointments or run remote diagnostics. The Remote Services feature also supports a digital key function. This ensures that only the owner and people authorised by the owner can unlock the car.
The Porsche Mission E's entire body is made up of a mix of aluminium, steel and carbon fibre reinforced polymer. The 21-inch front wheels and 22-inch rear wheels are made of carbon. The battery, which is developed using the latest lithium-ion technology, is mounted in the underbody and is spread across the length of the car to distribute weight uniformly to the two drive axles. This also results in a good centre of gravity and good balance.
The styling cues of the Mission E resemble those of the 918 Spyder and other Porsche race cars. The four-point Matrix LED headlamps lie within the air inlet while the rear end gets an illuminated three-dimensional Porsche badge on the black glass element. The overall design resembles that of a 911 except that it features two counter-opening doors without a B-pillar.

PORSCHE AT THE 2015 FRANKFURT MOTOR SHOW
|Tradition and the future Porsche sports car concept: Mission E Debut: The New Porsche 911 Carrera This is what it might look like the Porsche of tomorrow. Together with the new 911 Carrera, Porsche is presenting the "Mission E" concept car at the IAA in Frankfurt from 17 to 27 September. The concept car is a coherent design of a sports car with an electric drive and all of the traits that make up a Porsche. In the Mission E, an entirely new spread is experienced between performance and efficiency supplemented by a futuristic display and control concept. The joint premiere with the new generation 911 Carrera has symbolic character. The first all-electrically powered four-seat Porsche of the 21st century represents the future of a concept that made the 911 the most successful sports car ever for over 50 years. The 911 Carrera and Mission E share one clear statement, namely that excellent sporty performance can be combined with maximum efficiency the traditional Porsche values. In the new generation of the classic 911 Carrera sports car, innovative turbocharged engines stand for these values. The message of the concept car is E performance. This means that even an electrically powered Porsche naturally fulfils all requirements related to performance, range and driving dynamics. The Mission E concept car shows how Porsche envisions the future of the electric sports car. The fascinating design of the four-door car with four seats bears many references to the 911 while revealing the Mission E to be a Porsche at first glance. The passionately designed sports car with all-wheel drive develops a total power of over 600 hp, which can be conver ted into typical Porsche driving dynamics. The driving range of the Mission E is over 500 kilo metres, and the innovative 800-volts battery charging system Porsche Turbo Charging re duces charging time to just slightly longer than it takes to fill a car's fuel tank today. At the quick charge station, it takes just over fifteen minutes to provide enough charge for around 80 per cent of the total range. In keeping with the car's purist interior, the control and dis play concept is intuitive with eye-tracking and gesture control as well as innovative functions. The new generation 911 Carrera makes its debut at the IAA with new turbocharged engines, optimised chassis and the entirely new Porsche Communication Management system with online navigation. The turbocharged three-litre flat engine in the 911 Carrera has a power output of 370 hp (272 kW). In the 911 Carrera S it even generates 420 hp (309 kW), thanks to such features as modified turbochargers. Also excellent is the significant increase in torque together with an improvement of just around 12 per cent in fuel economy. The 911 Carrera has a maximum torque of 450 Nm and the 911 Carrera S even has 500 Nm. This torque is available from a low 1,700 rpm over practically the entire engine speed range. At the same time, the new engines with their maximum speed of 7,500 rpm are very free-revving and passionate. World premiere of the first battery-powered four-seat concept car from Porsche Porsche Mission E: 600 hp, 500 km driving range, 15 minutes charging time In presenting the Mission E at the IAA in Frankfurt, Porsche is introducing the first all-elec trically 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. Key specification data of this fascina ting 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 acce leration in under 3.5 seconds and a charging time of around 15 minutes to reach an 80 per cent charge of electrical energy. Instruments are intuitively operated by eye-tracking and gesture control, some even via holograms highly oriented toward the driver by automati cally 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 permanently-excited synchronous motors (PSM) similar to those used in this year's Le Mans victor, the 919 hybrid accelerate the sports car and recover bra king 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 Vectoring which automatically distributes torque to the individual wheels transfers the drive system's power to the road, and all-wheel steering gives pre cise, sporty steering in the desired direction. This makes the Mission E fit for the circuit race track; its lap time on the North Loop of the Nürburgring 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 every day practicality. Accordingly, the Mission E can travel over 500 km on one battery charge, and it can be charged with enough energy for around 400 km more driving range in less than 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 that 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 connec ted to a conventional 400-volt quick-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. Low centre of gravity for superior driving dynamics Another feature that is typical of a Porsche sports car is a lightweight concept with optimal weight distribution and a low centre 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 excep tionally good balance. In addition, it makes the sports car's centre of gravity extremely low. Both of these factors significantly boost performance and a sports car feeling. 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. Design: fascinating sports car with Porsche DNA Every square inch, every angle, every radius of the Mission E reflects one thing above all else: emotional sportiness in the best tradition of Porsche design The starting point is the sculpture of a sport saloon with a low height of 130 cm with sports car attributes from Zuffenhausen that embodies visible innovations such as its integrated aerodynamics. Distinc tive 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, 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 typical 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. 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: in stead of the classic door mirror, inconspicuous cameras are mounted on the sides that con tribute to the car's exceptional aerodynamics. The rear design underscores the typical sports car architecture. The lean cabin with its accelerated rear windscreen, which draws inward at the rear, creates space for the sculpted shape of the rear wings that only a Porsche can have. A three-dimensional "PORSCHE" badge illuminated from inside hovers beneath an arch of light that extends across the entire width in a black glass element. Interior: light and open with four single seats 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 practi cality. 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. Display and control concept: intuitive, fast and free of distractions A new world based on an innovative display and control concept opens up before the driver. It is intuitive, fast and free of distractions created for the sports car of tomorrow. The fili gree driver's display is curved, low-profile and free-standing. The instrument cluster shows five round instruments they can be recognized 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. The controls are just as innovative. An eye-tracking system detects, via camera, which instrument the driver is viewing. The driver can then activate the menu of the instru ment 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 recog nizes 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. Holographic display with touch-free gesture control 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 inte grates 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, cli mate 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. More over, driver or passenger can use a touch display on the centre console to control secon dary functions such as detailed information menus. The concept vehicle 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 con veniently 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.
