Re: 6.6 kW OBC on ALL (US?) Leafs,
DaveinOlyWA: 2018 LEAF! confirms it. He apparently was invited by Nissan and was in a test drive video. I will be going to a (now full, had to RSVP) EVent at Nissan's Sunnyvale research office in under a week. I'm 90%, there will be a Nissan corporate rep there who knows the '18 Leaf and can reconfirm.
Keep in mind that Tesla, the company has lost over $3.2 billion cumulatively (even when factoring in their profitable quarters). There was a piece in C&D long ago (wish I could find it) that basically said that any automaker can make a great car given a huge or unlimited amount of $. But the problem is, they need to meet a certain price and profit point while providing what's expected at that price level. And, the price needs to be set in a way that the # of projected units sold --> profit.
You won't sell any $100K or $200K cars that are like Nissan Versas. Yet Lamborghini can't sell cars like their current sports cars for $15K.
Tesla clearly can produce cars with incredible range, straight line performance, an awesome DC FC network while having a great brand image but hasn't been able to do it at a profit despite them being expensive cars w/theoretically high margins. High margins are generally tough(er) on cheaper cars.
