Problem is, now the rest of the industry is 10 years behind. They were hoping to just buy this tech from their suppliers, but so is everyone else. All profit gone in a bidding war. Making your own requires double-digit billions of investments (OK, plausible) and 10 years lead time. Let's be super charitable and say 5 due to the existence proof and leaky personnel. Now they've got to catch up while their newly equal-sized competitor eats their lunch.
Classic innovator's dilemma, and it's as obvious today as it was in 2013. Probably more.
Technically charges at 350kW, but good luck finding more than a 50kW CHAdeMO along your route. Especially during congested hours. Porche claims intention to install 800 of the fastest charging points globally by 2020, but after years of dragging feet, onus is on them to prove it.
This is what most casual observers fail to get. It's not about the specs of the cars themselves, it's about thousands of small details in production & distribution infrastructure, charging technology and UX that go deeper than just paying a subcontractor to slap it on top.
Many manufacturers can, with a proper effort, make something that seems convincing at a casual glance. But creating a properly competitive product is hard and will take years. Along with a cultural change that I think almost none will mange.
