Porsche Concept Study: Mission E (The Auto Channel)

Ever since Tesla’s Model S went on sale in 2012, the start-up automaker has had the market for high-end electric cars to itself. But that is changing as other automakers start to introduce their own models.

This week, at the Frankfurt Auto Show in Germany, Porsche unveiled its all-electric Mission E concept car. A four-door, four-seat luxury performance sedan with futuristic 911 design cues, Mission E will be the first all-electric model Porsche will offer to the public.

Porsche, a German brand, maintains that the vehicle, though it is a concept car, is firmly based in reality and is expected to arrive in showrooms within five years. At the same time, it provides a window into the future of all-electric cars — more range, faster charging and more speed.

...Comparisons with the Tesla Model S — which starts at around $71,000 — are inevitable. Like the Tesla, the Mission E concept’s battery pack, made up of lithium-ion batteries, is in the floor for a low center of gravity.

And while the Model S uses a 375-volt battery that can be charged to 80 percent in about 45 minutes using its Supercharging system, Porsche goes bigger with an 800-volt battery.

Porsche claims the Mission E’s range is well over 300 miles — surpassing the Model S’s 253 miles — even when driving hard, as auto enthusiasts are known to do. Depleted batteries can be recharged to 80 percent in 15 minutes with Porsche’s Turbo Charging system. The charging system’s network will take time to develop properly, and the battery’s durability must be further tested under performance conditions — two reasons Porsche isn’t rushing production. Mission E can also recharge at existing 400-watt charge stations.
