2018 Porsche Mission E: 600-HP electric sport sedan concept targets Tesla

Porsche is fighting Tesla with an electric sedan all its own: the sleek, mid-size four-door Mission E sedan. Porsche debuts the car officially today at the Frankfurt Motor Show.

Perhaps no German prestige carmaker was more rattled than Porsche by the sudden appearance of electric-car startup Tesla Motors.

With the sports-car brand having just launched its first sedan, the Panamera, the arrival of the Tesla Model S in 2012 offered an alternative take on a large luxury sedan: one offering stunning performance not from a huge V-8 but from electric power.

Now we can see a first draft of how Porsche plans to fight back.

The sleek, mid-size four-door Mission E sedan concept looks as much like an elongated 911 sports coupe as it does the hump-backed Panamera--and it's moved solely by a 600-horsepower battery-electric powertrain.

Porsche will debut the car officially today at the Frankfurt Motor Show, but it displayed the Mission E last night at an event for invited press. It says it will decide by December whether to put it into production.

The concept is evidence that Porsche plans to offer a second sedan, one smaller than the Panamera--and has Tesla Motors [NSDQ:TSLA] directly in its sights as it does so.

Powered by a battery pack of unspecified capacity, the Mission E uses two electric motors--one per axle--for an all-wheel-drive system that distributes torque to each wheel as necessary to maximize power delivery without wheel slip.

All-wheel steering adds to the torque vectoring for even sharper roadholding, and Porsche says it will do 0 to 62 mph in 3.5 seconds--and can lap the famed Nürburgring circuit in less than 8 minutes.

Range is estimated at 310 miles, though that figure is likely based on the NEDC cycle used in Europe; a comparable EPA range for the U.S. would likely be around 20 or 25 percent lower.

Porsche also claims the Mission E can be recharged to 80-percent capacity in just 15 minutes, using an 800-Volt charging system.

Such a system doesn't exist today--even from Tesla--leaving open the question of how such fast recharging would be accomplished in real life.

The body of the Mission E is a mix of steel, aluminum, and carbon-fiber reinforced plastic (CFRP), with rear-hinged "carriage doors" giving access to the rear seats without requiring a middle pillar.

The battery pack--like that of a Tesla Model S--is located under the floorpan from axle to axle, side to side, giving it a very low center of gravity.

The Porsche concept has just four seats, but the lack of a driveshaft tunnel gives the interior a more open feel. A production version would be more likely to offer a three-passenger back seat.

The Mission E's dashboard is the most futuristic part of the concept, with a holographic display extending to the front passenger area that portrays individual apps for climate control, navigation, or infotainment systems.

These are stacked in "virtual space" and arranged in a three-dimensional array, allowing users not only to select each one but to control them using hand gestures.

This "motion control" is detected by a collection of sensors that interpret each gesture: A grasping gesture means select, while pulling means alter the setting.

More traditional drivers or passengers who prefer not to wave their hands in the air can control the same functions on a touchscreen display and get more detailed information in deeper menus.

Like several concept cars before it, the Mission E dispenses with protruding door mirrors, replacing them with camera-based displays at the lower corners of the windshield.

The cameras themselves are mounted in the front fenders, producing far less aerodynamic drag than old-fashioned mirrors on doors--though Porsche will have to think through the effects of heavy rain and snow on the lenses.

The displays can also superimpose safety information and other relevant data on the rear-view images.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
