Porsche
Mission E Concept
In
presenting the Mission E at the 2015 IAA in Frankfurt, Porsche is introducing
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. 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 energy. 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.
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. 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 airflow 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: instead of the classic door
mirror, inconspicuous cameras are mounted on the sides that contribute 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.
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 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. This makes the Mission E fit for the circuit
race track; its lap time on the Nürburgring Nordschleife is under the
eight-minute mark.
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 battery charge, and it can be charged with enough energy for around 400 km
more driving range in about 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 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.
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 exceptionally 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.
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 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.
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.
