Test-driving the Porsche Mission E

Porsche electric Mission E concept

Automobile magazine contributor Georg Kacher recently got a chance to drive one of the few existing prototypes of Porsche’s Mission E, and was also able to glean some technical details about the upcoming EV.

Porsche told Kacher that every Mission E will have all-wheel drive at first – a rear-wheel-drive version may be offered in the future. There will be three performance levels: 536, 670, and 804 hp. The front motor will be the same in all versions, and will produce 160 kW at 16,000 rpm. Different rear motors will be used depending on the performance level. Porsche will use synchronous permanent magnet motors, which it says offer superior continuous performance in a smaller, lighter package. The powertrain also includes a two-speed transmission and an electronically controlled limited-slip rear differential.

The Mission E is not intended to challenge Tesla’s P100D as the fastest gun in town, but will get to 60 mph in a respectable 3.5 seconds. The battery chemistry and a complex battery cooling system are designed to let the Mission E handle high-speed driving on the Autobahn for an hour or more and still be capable of up to 300 miles of range. Top speed is 155 mph.

“This car is smog-free but is also a hoot to drive thanks to the low center of gravity, the dedicated air suspension, and the precise steering,” said Project Engineer Michael Behr. “Make no mistake: This is a proper Porsche through and through.”

Porsche has not finalized pricing, but sources say the base model will start between $75,000 and $80,000. The Mission E is scheduled to go on sale in 2019 as a 2020 model. Porsche plans to build 20,000 per year, but could increase that figure to 30,000 if demand is strong.

    Strange to announce a car so far ahead of production as its competivity is cannot be foreseen.

    • Joe Jackson

      do you mean competitors or competitiveness ? no such word as competivity.

      • brian_gilbert

        ANyone can create a word. If a significant number of people use it then it is added to dictionaries. There is no ‘ official’ dictionary.

    • Ramon A. Cardona

      Competivity? As to announcement now it is called publicity! Thanks

      • brian_gilbert

        Luxky for them it was not a diesel engined car.

  • Joe Jackson

    Glad to see someone has taken on board a gearbox has it’s advantages – even in an EV.

    • nordlyst

      It also has disadvantages, and IMO they more than outweigh the advantages – at least in any “everyday” car that is interesting to me as something I might consider buying.

      I would much rather have top speed limited to something that is still more than enough (say 150 kph), or use the trick Tesla does in their dual-motor AWD cars: tune each motor for optimum efficiency at different speeds, and predominantly use the most efficient motor when cruising at any particular speed. This trick is why dual-motor Teslas get about 5% more range than their RWD counterparts.

    While developing the Tesla Model S, Tesla attempted to develeop an automatic two speed and failed miserably. If any car needed more than a single speed, it is an electric car.The Porsche Mission e, like all American and European and many Aian cars, uses th e CCS charging protocol, which has been uprated to 350KW and 500KW, versus Tesla’s much slower 120KW Supercharger.Porsche demonstrated the ability to rechrage twice as fast as Tesla. EvGo is installing 350KW CCS chargers coast to coast, even though there is not yet on the road any vehicle that can take advantage of their enormous power. Of course a 350KW charger can recharge any CCS vehicle that doesn’t require more than 350 KW. Obviously Porsche is going to build a higher performance EV to take on and equal or surpass the Tesla roadster or the 100P Model S. It may or may not happen to be the Mission e, their first EV.

    • Gary

      EvGo’s systems are mostly placed in high population areas. I can make it coast to coast (from the Northwest) on the Tesla system.. not even close with EvGo.

    • Don-Flyboy

      Just another Tesla Naysayer.
      Tesla (Elon Musk & Associates) has caused a revolution!! Should the newer vehicles be better? Certainly!! Of Course! But honestly, was it the “automotive establishment” that brought about a vehicle that is Earth Friendly? Hell no. Why? Too Stupid To Care!! And a lot of gas car nuts won’t buy EV’s…but many of us will switch. I have a Ford Focus EV as my daily driver (could not justify the cost of a Model S a few years ago). I will NEVER go back to a gas car. EV’s ARE Superior!! L-O-V-E that it has NONE of those “Regular Replacement Parts” nor pollution that all gas cars produce. (Coal is only 30% of US electricity, [and declining because we already burned up the good stuff and the soft dirtier bitumin is what’s left] so don’t give me that baloney about smokestack vs. tailpipe). If it were not for Tesla there would be little hope for your grandchildren’s Grandchildren to inherit a decent planet not headed to polluted failure because of an ignorant species far too immersed in greed and self aggrandizement. Enuf said.
      On the other hand, I personally doubt Elon’s vision of an “interplanetary humanity”, as we are evolved critters of this planet, this gravity level and this atmosphere. Mars gravity and a “manufactured” atmosphere (if it could even stay “attached” to MARS because of the low gravity)….simply will not support earth critters for long….they would take eons to evolve to thrive in that planet’s parameters…IMHO… (me being a retired Senior Engineer McDonnell/Boeing of 27 years). So, IMHO we really need to educate & re-establish humans as Shepherds of THIS planet (instead of murdering War Mongers) and look towards voluntary wiser birth control to reduce the human population to levels that are sustainable based on this planet’s resources. Can we mine the moon and other planets instead of polluting this one? Absolutely! We can rotate crews to reduce the effects of off earth activity.

      @Arther Burnside… Tesla is also part of the CCS consortium and unlike many other EV’s, Tesla can use ANY charging system so if CCS becomes a standard, I’m certain Tesla will provide a CCS adapter for it’s vehicles giving it access to all Tesla Superchargers as well as all the currently non-existent CCS 350kW chargers.
      Unfortunately, privately built charger stations are usually poorly maintained and often out of service when EV’s pull up for a drink of ev juice. The Tesla Charging network is both reliable and well placed in the US, Europe, China and other major global markets.

      • nordlyst

        > “unlike many other EVs, Tesla can use ANY charging system”

        Tesla doesn’t sell CCS adapters as far as I know..?

        And in any case, it is a matter of the adapters, not the car itself. Electricity is very malleable and the various protocol’s signalling schemes are handled in software. In other words, there’s no fundamental difference between Tesla’s cars and other EVs in this respect.

        My LEAF could technically very well charge at Tesla’s superchargers, as well. The reason it can’t it that Tesla won’t allow it (and someone would have to make an adapter).

    • Cris Baker

      You say “Tesla’s sparsely spread Supercharger network.”

      Yet don’t Tesla have more superchargers in more places than the CCS network? So your statement is egregiously biased misinformation at its most outrageous….

      • Ed

        Crossing the US in a Tesla is already a snap. Here is where we expect Tesla to be by the end of 2018. Others will figure it out at some point, but remember this: commercial charger companies – not directly tied to an automotive maker – will want to put chargers in metro areas when there is lots of use…and revenue. Tesla’s chargers are located to allow city-to-city driving. Tesla is committed to clean transport ONLY…and that drives them to do this.


    • Ed

      And Tesla will surely sit still and let other car companies surpass them in technology, right?!

    • Freepat 75014

      Ha ha…. And NOBODY has yet seen an end to end 350kW charge of any Mission E prototype… Bet 800V is not at all a trivial thing. Hence most of these to-be 800V / 350kW chargers are yet <400V / 150kW, up-gradable to 350kW… on day.
      And you seams to have missed Tesla MegaCharger plug during the Semi Truck announcement last month…With Modular 4 x 320 to 400kW DC pairs of very thick pins. This will make Mission E 800V chargers a lot less attractive by 2019/2020…

      • nordlyst

        Actually, I believe it is a rather trivial matter, provided the pack voltage is also doubled. It is bigger currents, not higher voltage, that require significant changes to the hardware (and increase cost substantially).

        I don’t know what you mean by end-to-end here (from solar panel to wheel? from empty pack to full? something more original?) but I think the reason we haven’t seen it is that the car is still a long way from market. Porsche has something on their hands that to a lot of people with little or no knowledge of electronics will see as “high tech”, and they are probably wise not to show it off until much closer to launch.

        • Freepat 75014

          Your.re still misding the high curent leaks across thin air when operating aboie 600 volts in consumer space. If inceasing voltage was that simple, Tesla would have put 800V or more in Superchargers v1 & v2. Not a big Deal to put more battery cells in séries to double voltage and allow lower current amps hence thinnee câbles. But There is a hic !!!

    • nordlyst

      What a classic mix of ignorance and confidence you put on display!

      > If any car needed more than a single speed, it is an electric car.

      As wrong as can be. Electric motors develop excellent torque at 0 RPM and therefore don’t need low gears just to get going or be able to drive slowly. A combustion engine typically develops almost no torque at all below 800-1000 RPM, and redlines at 5500-7000 RPM. In other words, it has a useable power band where the fastest rotation is about eight times the minimum rotional speed. Hence, to have a top speed of 150 and therefore ability to cruise at 90 without running the engine at very high revs, you must have gears to even be able to move at speeds below 20. (Whether these are kph or mph doesn’t matter – it’s simply a matter of the ratio between the fastest and slowest rotation speed where the engine produces useable torque, which determines the ratio of possible minimum and maximum speeds.)

      And the more you look into the details, the more wrong your claim becomes. Not only is the above-mentioned ratio infinite for an EV since it develops lots of torque at 0 RPM, but it’s torque curve is almost flat. ICE engines produce useable torque from just above idle to the redline, but it is much, much less than the maximum torque. And pushing the engine by running it under load at low or high RPMs increases wear dramatically. In practice, a typical ICE engine must be operated, under load, in the much narrower band from about 2000 to 4000 RPM the majority of the time. So rather than an 8:1 ratio we are more realistically speaking of a 2:1 ratio. Which is why ICE doesn’t really work with two gears either – and may still benefit from more gears up to at least eight, which of course is what you get in most luxury ICE cars these days.

      > the CCS charging protocol, which has been uprated to 350KW and 500KW

      Incorrect. 350 kW has been formalized, but not more.

      > Porsche demonstrated the ability to recharge twice as fast as Tesla.

      I haven’t seen it, but in any case comparing a technology demo to an installed and fully operational charging network is meaningless. I’m sure charging speed will rise way beyond the 120 kW Tesla’s superchargers currently offer. But there is zero indication of anything beyond “charging speeds will probably increase in the future” in Porsche doing such a demo, if they even have.

      > Of course a 350KW charger can recharge any CCS vehicle that doesn’t require more than 350 KW.

      It’s kW, not KW (K is the symbol for the temperature unit Kelvin, not the SI prefix for a thousand, kilo). And a 350 kW CCS charger can recharge CCS cars regardless if they can take less than 350 kW, exactly 350 kW, or much more than 350 kW. I’m sure you really knew this already, but it goes to show you type faster than you can think, and you really shouldn’t. 🙂 There isn’t really a minimum required charging power that is necessary to charge a battery, certainly nothing in the vicinity of 350 kW – as you ought to understand since these cars will also be able to charge at home, at 2 kW, 3 kW, 6 kW and perhaps 11 kW or even 22 kW…

      When it comes to your opinions about the “patently obvious” – I guess that is why you don’t feel there’s any need to substantiate your claims? – charging standard that will become the one and only global standard, well, you’re welcome to your opinion. Let’s just say that with the level of understanding you demonstrate, I am not inclined to assume your crystal ball sports a particularly clear image, and no better than my own. I will just point out that 0.1% of the world’s cars are EVs, and I don’t think it is necessarily too late for a new and better standard to emerge. It also isn’t particularly difficult or very expensive to equip chargers with multiple cables (for example CCS and some new standard we haven’t seen yet).

      Technically, CHAdeMO and CCS are both horrifically clunky and far from as user-friendly as Tesla’s much more elegant design. Neither impresses me much. CHAdeMO has one major technical advantage over CCS, namely that it supports V2G. But this can probably be fixed in future CCS versions.

      Otherwise I agree that CCS looks like the likely winner, in the battle with CHAdeMO, at least outside of Japan – but because of manufacturer support, not technical superiority.

    • Ralph Wolf

      Don’t compare VW/Porsche’s someday vaporware to what Tesla has here and now. Tesla isn’t sitting still either.

      You have to compare what is available today from each company.

      Please point me to a map of CCS/COMBO chargers that can do more than 100kw.

      I found article saying there are 4000 CCS chargers in Europe, but the bulk of them are 20-50kw. I think chargers in the 100-350 kw range are still only anecdotal/demo systems.

      Tesla has 135kw SCs all over the place today.

  • Freepat 75014

    Did he see a full SuperCharge of this Mission E at real 800 Volts and 350kW on a CCS-Combo charger capable to deliver this power and Voltage ????
