Which promise made by electric-car maker Tesla Motors took 18 months to come to fruition?
And what's the 2016 Toyota Mirai hydrogen fuel-cell vehicle really like to drive?
This is our video look back at the Week In Reverse--right here at Green Car Reports--for the week ending on Friday, December 19, 2014.
Friday, we had a brief exclusive on the first Tesla battery-swapping station, which will open next week in Harris Ranch, California.
That's about 18 months after Tesla CEO Elon Musk unveiled the concept of Model S battery-pack changes in a flashy demonstration.
In this pilot program, only invited Tesla owners will be able to get their packs swapped--and they'll have to make an appointment in advance.
They'll also have to pay a fee, perhaps around $50.
We also reported on our drive of the 2016 Toyota Mirai hydrogen fuel-cell car.
It drives a bit like a Prius hybrid, doesn't have much acceleration at highway speeds, and has gotten harsh reviews for its looks.
On Thursday, we pointed out that in just one year, electric cars have gotten cleaner--and we explained how that happened.
It's all about the grid, of course--and electric grids are getting cleaner across the country.
Wednesday, we visited the New York Motorcycle Show--and came away disappointed.
Unlike previous years, there was only a single electric motorcycle on display: the Harley-Davidson Livewire concept.
The day before that, Tuesday, we watched in glee as a Tesla Model S P85D simply obliterated a Ferrari in an impromptu drag race.
But, kids, please remember: NO street racing! Seriously.
Monday, we looked at the cheap gas prices that everyone's rejoicing over. Many say they'll cause electric-car sales to fall, but we're not convinced.
Over the weekend, we answered a simple question: What's the best electric car for average consumers to buy? The answer may not surprise you: It's the Nissan Leaf.
Finally, we noted that Toyota's luxury brand, Lexus, says it's keeping an eye on Tesla and its mall stores. It even called those stores a 'clever' idea.
But while Lexus might love to offer the Tesla experience, state dealer laws ban it from showing cars in mall stores and letting buyers order them online.
In other words, if you want to buy a Lexus--now or in the future--you still have to do it through a dealership.
