People who post negative responses to this are the people who get it. The people who think the Porche Mission E is on the same playing field as Telsa are the ones who just don't get it.
The electric car is the EASY part. Anyone can build an EV. That doesn't impress me.
1. Without a long distance charging network in place, you cannot do inter-city travel in the Mission E. There are currently a grand total of TWO 800V chargers compatible with the future Mission E, both built in Berlin primarily as showpieces. Nothing can currently charge on them. And they're limited to 150 kW right now anyway. And seeing as how they're both in Berlin, they don't even assist with inter-city travel. Without the long-distance charging network, all you have is an in-city Leaf that looks better.
On a side note, I don't buy the 15-minute 80% recharge claim, either. C rate is C rate, regardless of what voltage you charge at. 300 mile range will be somewhere around 90-100 kWh capacity, similar to the Model S 100D. 350 kW charging is a C rate on the order of 3.5 to 4. Unless they have a new magical chemistry, that's going to trash the battery.
2. To build cars in volume, you have to have your own battery factory. If you want to buy 3rd-party batteries, you have the Japanese manufacturers like Panasonic, who can make a limited supply of Li-Ion cells that are using a preferred chemistry for EVs, and then you have the Chinese manufacturers who can supply more cells, but they're common chemistries that don't do well in EVs. If you need good cells in volume, you need your own factory.
3. EVs have drastically lower maintenance and repair than a comparable ICE, thus they directly impact the major revenue stream of the dealerships. Dealerships have no incentive to sell EVs since they undermine their profit. How does Porsche plan to circumvent this issue?
I haven't heard a peep out of any other auto manufacturer about how their coming EVs are going to work without addressing these three problems. Chevy's Bolt got a ton of "Tesla Killer" press, and they can build a maximum of 30K of them per year because they don't have a battery factory. I can't drive it from Houston to Dallas and back in 1 day, because they have no long-distance charging network (and on the Bolt, no fast charging capability at all). And I can't even get one in Texas, because no Chevy dealer even wants to talk to you about one.
The MIssion E is in the exact same boat until Porsche addresses these issues. So the car will (supposedly) be out in 2019 -- when are the other problems getting fixed?
Wake me up when another manufacturer actually has a comprehensive EV plan, then maybe I'll be impressed.
