The future of mobility in Southern California will rely on various energy sources to fuel the automobile. Electricity is one of those choices. Though sustainable, there are concerns over electric vehicles that consumers still have, even since there are plenty of them on the road today.
One of those concerns is range. Could there be an electric vehicle that can have a range from a full battery that could equal to a normal automobile’s gasoline consumption? Current battery technology is getting there, so what more could be done to simply go further on a full battery charge?
Porsche may just have the answer. The Mission E concept.
Unveiled at IAA 2015 in Frankfurt, Porsche showed what it can do when it is also committed to the future of mobility by creating a technological feast underneath a powerful and evocative skin. However, there was one mission that it had to achieve – maximum range on a full battery.
At the core, the Mission E is focused on is the target of a predicted 500-kilometer range – approximately 310 miles – in this electric vehicle. This is achievable using an 800-volt system emitting an equivalent to 600 horsepower from two permanent magnet synchronous motors (PMSM). As tested, Porsche achieved a 0-100 km/h time of 3.5 seconds.
When the system is being charged from a Level 3 plug-in unit, the Mission E would go to an 80% charge in just 15 minutes. It is possible to drive to drive this car from Torrance to San Francisco and back with two-to-three charging stops. This is another goal Porsche had in mind when developing this system.
If this system sounds familiar, the PMSM system was used on the 919 endurance race cars that ran at Le Mans. Even in a hybrid setup, two PMSM units enabled energy recapture and transfer to reduce the reliance on fuel and extend EV drive modes further. Without a gasoline or diesel internal combustion engine on board, the two PMSM units will behave the same way by inducing energy transfer that keeps the vehicle at higher speeds with minimal penalty on battery drain.
The other aspect of the Mission E’s drivetrain is the doubling of the voltage to 800. By doing so, it increases capacity within the system to drive extended battery use and drain. It also opens up a port system that enables faster charge-ups. Charging is also flexible, even with a 400-volt charging unit (true Level 3) all the way down to regular household current. Porsche also states that a special garage floor unit could be enabled underneath the car for dedicated charging from the household current. All of this is named under the brand of Porsche Turbo Charging.
Even with battery power, it will drive like a Porsche. What enhances the Mission E is a low center of gravity thanks to placing the lithium-ion battery unit underneath the cabin in-between the front and rear axles. The result is excellent driving dynamics – flat cornering, with a solid ride. Even with the battery unit integrated into the chassis, the Mission E is designed to be light in eight by using advanced materials, such as carbon fiber. The wheels are in carbon 0 sized at 21-inches up front, 22-inches in the rear.
The Mission E is designed as a four-seat, four-door car. Interior technology was also showcased, including a holographic display for the instrumentation and touch-free controls. The entire car could be configured from a tablet via Porsche Car Connect, enabling full customization to enhance the driving experience. Rearview mirrors are essentially cameras that could be also be customized and configured for optimal vision.
This technological masterpiece is an example of what Porsche can do to meet the mobility needs of the future. Expect some of these technologies to appear in future Porsche models as time goes by. The Mission E is a possible machine, not only to satisfy Porsche's loyal enthusiasts and owners, but to meet California's increasing requirements on emission controls towards further improving the air quality of this state.
Those standards are being met by our most sustainable models currently on sale: The Panamera S E-Hybrid and Cayenne S E-Hybrid. Though 918 Spyder production has ended, experiencing one is to see how far Porsche has come to meet the needs of efficiency and cleaner emissions. These models can be seen at Pacific Porsche today.
