2016: The year of the autonomous-car promise

About half of the news we covered this year related in some way to The Great Autonomous Future, or at least it seemed that way. If you listen to automakers, by 2020 everyone will be driving (riding?) around in self-driving cars. But what will they look like, how will we make the transition from driven to driverless, and how will laws and infrastructure adapt? We got very few answers to those questions, and instead were handed big promises, vague timelines, and a dose of misdirection by automakers. There has been a lot of talk, but we still don't know that much about these proposed vehicles, which are at least three years off. That's half a development cycle in this industry. We generally only start to get an idea of what a company will build about two years before it goes on sale. So instead of concrete information about autonomous cars, 2016 has brought us a lot of promises, many in the form of concept cars. They have popped up from just about every automaker accompanied by the CEO's pledge to deliver a Level 4 autonomous, all-electric model (usually a crossover) in a few years. It's very easy to say that a static design study sitting on a stage will be able to drive itself while projecting a movie on the windshield, but it's another thing entirely to make good on that promise. With a few exceptions, 2016 has been stuck in the promising stage. It's a strange thing, really; automakers are famous for responding with "we don't discuss future product" whenever we ask about models or variants known to be in the pipeline, yet when it comes to self-driving electric wondermobiles, companies have been falling all over themselves to let us know that theirs is coming soon, it'll be oh so great, and, hey, that makes them a mobility company now, not just an automaker. A lot of this is posturing and marketing, showing the public, shareholders, and the rest of the industry that "we're making one, too, we swear!" It has set off a domino effect – once a few companies make the guarantee, the rest feel forced to throw out a grandiose yet vague plan for an unknown future. And indeed there are usually scant details to go along with such announcements – an imprecise mileage estimate here, or a far-off, percentage-based goal there. Instead of useful discussion of future product, we get demonstrations of test mules, announcements of big R&D budgets and new test centers they'll fund, those futuristic concept cars, and, yeah, more promises.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

Hyundai's next fuel cell SUVs have a reported range of 348 miles

Hyundai's next line of fuel cell SUVs will have a range of 348 miles, besting the current Hyundai Tucson by 30 percent, according to Nikkei. Hyundai reportedly plans to roll out its second generation of fuel cell SUVs in January 2018. A 348-mile range would put Hyundai ahead of the Toyota Mirai, which travels 312 miles per fill-up, but behind Honda's new Clarity Fuel Cell, which travels 366 miles, as MotorTrend points out. Hyundai is apparently looking to price the 2018 fuel cell SUVs at about $50,000 a pop. Additionally, Hyundai is set to debut its fuel cell-powered commercial bus in 2017, putting it in direct competition with Toyota, which has plans to do the same, Nikkei says.Hyundai is also preparing to release its first all-electric vehicle, the Ioniq, in the United States next year. That model comes in fully electric, plug-in and gasoline-hybrid versions. Take a look at it in photos or, if you're in Los Angeles, take a free two-hour spin in a branded Ioniq via the WaiveCar ridesharing app. This article by Jessica Conditt originally ran on Engadget , the definitive guide to this connected life.
