Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments. For more Detroit coverage, you can check out Autoblog's picks for the best in show, listen to our podcast or look at the best images from all the reveals. Finally, don't forget to watch Editor-in-Chief Greg Migliore hand over our 2019 Technology of the Year award.

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 Genesis Coupe spotted with rumors of a V8 underhood

Our spy shooters have captured a Hyundai Genesis Coupe mule testing in Sweden. This is merely the current body cut-and-pasted to fit new internals, so don't be disappointed by its looks; we're looking forward to inspiration from the HCD-9 and perhaps grand touring inclinations on the production car whenever it appears. The photographers said they noticed the hood's been modified, perhaps to clear the 5.0-liter V8 from the Genesis sedan. That engine would be part of the plan to push further upscale said to be planned for the Genesis Coupe, along with the fender arch cutouts on this mule that push the wheels to the corners for a longer wheelbase that will make more room for passengers. Rumor has been that the next car will do a much better job of swallowing four adults. The company's HTRAC all-wheel drive is expected to be an option, Hyundai having said five years ago that the feature is being engineered into the Genesis family platform. A reveal probably won't come until sometime in 2016.
