Porsche 991/2 Carrera variants offered many advantages over the previous Porsche 991/1 Carrera variants powered with naturally aspirated engines.
Mission E concept was something completely different. Mission E is the first all-electric Porsche and its performance specifications and capabilities were similar to Porsche’s existing performance portfolio. The Mission E concept showcased the potential for an all-electric Porsche in near future.
Porsche Mission E is powered with two permanent magnet synchronous motors and this system is similar to the system in Porsche 919 Hybrid LMP1.
Porsche 919 Hybrid LMP1 won the 24 Hours of Le Mans twice and was equipped with a 2.0-liter inline-four engine and two electric motors in the front axle. Exhaust gasses of the car were used to spin a turbine that was connected to a generator that produced energy to be stored in batteries.
Porsche Mission E has four doors and four seats. It has an all-wheel-drive, and all-wheel-steering mechanical layout. Porsche Torque Vectoring system managed the power separately to each wheel to improve the efficiency of power delivery. The maximum power output is measured at 600hp.
0-62mph was achieved in less than 3.5 seconds. It was also stated that the owners of the car would be able to recharge the car up to 80% of the maximum stored energy in fifteen minutes.
To keep the center of gravity as closest to the ground as possible, Porsche engineers installed the lithium-ion battery into the car’s underbody. The battery pack ran the full length between the front and rear axles. This setup distributed the weight of the battery pack evenly and also lowered the center of gravity towards the ground, thus resulting in improved stability and handling.
The all-electric fully-charged range was measured at 300 miles. Porsche was also utilizing an 800-volt electric system instead of the average 400-volt system. This results in reduced charging times as well as the reduced overall weight of the vehicle.
The reduced weight is largely thanks to the use of smaller gauges, lighter cables from batteries to motors, and motors to batteries. However, the owner could utilize a 400-volt station to recharge the Porsche Mission E.
Porsche also introduced an induction charging system that the drivers could install on the garage floor, which allows recharging the car without any cable connection.
The body shell is made out of steel, aluminum, and carbon fiber-reinforced polymer. The body panels are made out of carbon fiber reinforced plastic.
The interior was designed in a way to make it look futuristic but without making it too unfamiliar. The transmission tunnel was absent, and instead of it, there was a passenger seat separator with holographic imaging capable user interfaces.
The bridge-style center console design from the Porsche Carrera GT was also incorporated into the interior of Porsche Mission E, but now there was an open space below it.
The traditional five gauge cluster system was also present, but now it was a completely digital OLED screen-based system.
A real-time driver monitoring system incorporated an eye-tracking system using a micro camera. This system observed the instruments that the driver was observing and provided an instant interface with the full available options for each gauge. This system also tracked the driver’s seating position and body height to provide a “parallax view” display, thus eliminating the situations where the steering wheel might block critical instruments from view.
The traditional rearview side mirrors were now replaced with micro cameras mounted in the front fenders, and two screens in the lower corners of the windshield displayed what’s behind. This was done to improve aerodynamic efficiency as much as possible.
Porsche chairman at the time, Matthias Muller revealed that the Porsche Mission E will go into production and will be available to the customers as a 2020 model year product.
