Porsche Mission E: here’s how you’ll charge the electric supercar

 Mission E to come in three power levels

 Charging bays will be pre-reserved

When Porsche first unveiled the Mission E back in 2015, it promised some impressive charging speeds – but details of how you’d actually charge the electric sports car were thin on the ground. Now, after installing its first lot of ultra-charging stations in Germany and the US, the car maker from Stuttgart has given us more details of its electric vision. And according to a new interview with Porsche's head of the electric development division, Uwe Michael, it’s quite complex.

First, Michael confirms that the Mission E will be able to achieve charging speeds of 400km (250 miles) in less than 20 minutes, but it’s how Porsche will manage the charging process that’s most interesting.

Porsche Mission E: using hardware and software for the best UX

Porsche wants to ease Mission E owners into the world of electric charging, and it’s going to use a combination of hardware and software to do it. For example, in a step above Tesla’s own Supercharger network, Michael says Porsche drivers will be able to easily reserve charging spots as part of a normal sat-nav-led journey.

‘Take the Turbo Charging Planner for our battery electric powertrains as another example,' said Michael. 'Quick-charge options are optimally matched to your route planning and charging pedestals are pre-reserved, meaning that you can gain that all-important advantage and lose as little time as possible. Added value of this kind helps to determine the essence of the brand.’

Interestingly, Porsche isn’t too keen on rolling out its fastest charging technology to everyone’s homes, either. Instead, it’ll offer an extended range of wall chargers, with different models catering for different cars and use cases.

‘We’ll also be able to tailor charging output to customer needs. For example, 3.6 kW for a plug-in hybrid or 7.2 kW for drivers who want to go faster in their Porsche vehicle. For purely electric vehicles, the customer can choose between 11 kW and 22 kW.’

Just like the charging reservation process, Porsche says the rates of charge can be chosen by the customer over the internet. It’s another way of getting more money out of those in a hurry, or business users – and it’s probably an idea we’re going to see more of in the future.

Porsche Mission E: trim levels

Porsche is planning to offer its Mission E electric sports car in three different power outputs, CAR has learned, and will price the fast four-door in a similar ballpark to the Cayenne and Panamera. This points to a launch price of around £60,000 in the UK when sales start in 2019.

Offering a choice of performance levels gives the Porsche EV a wider market appeal, different price points and an answer to the Tesla Model S, which also comes in 75D, 100D and P100D flavours. We understand the Mission E will be available with some very familiar-sounding badges, reflecting the performance ladder:

  • Carrera 300kW equivalent to 396bhp
  • Carrera S 400kW equivalent to 529bhp
  • Turbo 500kW equivalent to 661bhp

The all-electric four-door sports car concept that caused such a stir at the 2015 Frankfurt motor show, is entering the latter stages of development before sales start in 2019. We've caught it on test in -20C chill in Sweden - a brutal environment for a battery-powered car and Porsche's engineers are ensuring that the cells don't collapse in extremes of temperature and that range anxiety isn't brought on by a frost.

Our latest scoop pics follow on from earlier shots of prototypes in Germany benchmarking against a fleet of Tesla Model S and Model X electric cars (below). Hardly a surprise that, but proof of just how disruptive the Silicon Valley start-up has become.

These early prototypes were the first tangible evidence of the Model E inching closer to production. Clad in black camouflage, it's hard to make out much of the style but we're promised the finished cars will look more concept car than Panamera.

The boss speaks: Porsche boss gives details on the Mission E

Chairman Oliver Blume updated CAR on many of the key details of the project, including plenty of new nuggets:

  • On sale by end of 2019
  • Designed to plug gap between Panamera and 911
  • Electric-only powertrain, no combustion engines
  • Different power output motors will be offered
  • Badges 'likely' to follow conventional Porsche hierarchy (S, GTS etc)
  • Porsche Mission E 'priced like entry-level Panamera'
  • Different bodystyles possible in longer run

Speaking at the 2017 Frankfurt show, Blume said the project was on schedule and prototypes would be heading out on public tests soon. 'We are in series engineering phase,' he confirmed to CAR. Which is why it keeps popping up in our Spyshots section...

Porsche Mission E: the background

Porsche’s supervisory board confirmed in 2015 that the production version of the Mission E would be launched ‘by the end of the decade.’ This is the first fully electric Porsche – and it won't be the last. ‘With Mission E, we are making a clear statement about the future of the brand,’ said Porsche board chairman Dr. Wolfgang Porsche, speaking in 2015. ‘Even in a greatly changing motoring world, Porsche will maintain its front-row position with this fascinating sports car.’

Porsche Mission E: on sale by end of 2019

The Mission E production project is expected to create more than 1000 new jobs at Porsche’s Stuttgart-Zuffenhausen base. Around €700m are being invested in the site, with a new assembly plant on the way and the engine factory being expanded for the production of electric motors.

In the wake of the ongoing emissions scandal rocking Porsche’s parent company VW, electric drivetrain technology is being fast-tracked throughout the Volkswagen empire.

Porsche Mission E: concept debuts in Frankfurt

If the original 600bhp, 800-volt Mission E concept is anything to go by, the production car should be worth waiting for. The Mission E concept is a four-door sports car - a bit like a squashed Panamera, but with a stealthy swagger that turns heads. Especially in its matt white paint job with white and black alloys and neat detailing such as a full-width LED lighting bar for rear lights.

Those rear doors are suicide hatches, revealing a 2+2 cabin. But don't go mistaking this for a 911 (despite that echo in the rear window line)... this is an entirely new kind of Porsche, one to challenge Tesla and other EV upstarts. What's more, Porsche claims it'll lap the Nurburgring in less than eight minutes.

Porsche Mission E: specs and performance

Porsche claims the Mission E will pass 62mph in 'less than 3.5 seconds', dashing past 124mph in just a dozen seconds. Top speed meanwhile will be 'more than 155mph'. The dual-motor layout delivers four-wheel drive and the 911's four-wheel steering features for agility that would surprise most four-seaters. The batteries are mounted as low as possible within the composite construction for a ground-hugging centre of gravity.

Mission E: a new kind of Porsche

Time to recharge? Less than quarter of an hour for 80% charge with a new type of rapid-charge, claims Porsche. Then-Porsche chief (and now VW group boss) Matthias Mueller referred to refuelling as being like 'fast pit stops,' a reference to the Le Mans 919 hybrid sports car's experience at La Sarthe where Porsche won in 2015, 2016 and 2017. ‘We wouldn’t have been able to develop this car so quickly without the 919,’ he added.

Blume, who replaced Mueller as the chairman of Porsche, tells CAR that this quarter-hour recharge will be offered at launch in 2019. 'With 350kW fast-charging, this will be a reality. It will be enough for a 400km (250-mile) range on an 80% charge.' Total range with a full battery stands at 500km (300 miles).

Porsche Mission E: what will it look like? 

For sure. Over to Blume the boss: 'The design is fixed,' he told CAR. 'It is very close to what you saw two years ago at Frankfurt. It will be exciting but a bit different from the concept.'

Take a peek inside the Porsche Mission E's cabin: there are clever new holograms for certain instrument functions - and you control them using 2015's most popular new trend, gesture control. Expect to see this tech in production...
