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.

2017 Hyundai Elantra Sport aims to be the Korean Jetta GLI

We've had a good idea of what the upcoming Elantra Sport would be like thanks to Hyundai's reveal of the Avante Sport, the quicker version of the Elantra's Korean-market twin. Now we know just how similar the two are: essentially identical. The Elantra Sport features a turbocharged 1.6-liter four cylinder engine that anyone familiar with the Veloster Turbo will recognize. Oddly though, at 200 hp and 190 lb-ft of torque, the engine is rated 1 horsepower and 5 lb-ft of torque less than either the turbo Veloster or Avante. The front-wheel drive Elantra Sport can also be ordered with either a 6-speed manual or 7-speed dual clutch transmission. We're happy to report the Elantra Sport and its Avante twin will share a new multi-link rear suspension. This replaces the less sophisticated torsion bar suspension and will hopefully contribute to more agile handling. Hyundai did not announce whether the Avante Sport's optional "extreme package" anti-roll bars, springs and shocks would be available in the States. We certainly hope they will at least be an option. The Avante Sport and Elantra Sport will also share exterior and interior updates. These updates give the fastest Elantra a subtle, classy look. Larger intake vents, a rear diffuser panel, larger wheels and slightly extended ground effects all say sporty without shouting it. The theme continues inside with red stitching on the flat-bottom steering wheel and more aggressive "sport" seats. The Elantra Sport also finds itself in an odd position. Many of the performance cars in its size segment have moved up in power. There are some small sedans that come close to the Elantra Sport's 200 ponies such as the turbocharged Honda Civic, 2.5-liter Mazda3 and the lame-duck 2.4-liter Dodge Dart. But when it comes to enthusiast-oriented small sedans with at least 200 horses, there's only one true option: the Volkswagen Jetta GLI. In fact, the 210-horsepower GLI matches the Elantra Sport quite nicely, as it also features subtle styling and just enough sportiness to feel special. Hyundai has yet to announce pricing, but if it undercuts the German veteran by a significant margin, it could become a bargain choice for the driver who wants some, but not too much, fun.

2015 Hyundai Sonata plays a more mature tune

Hyundai's new North American CEO Dave Zuckowski pulled a silky sheet off of the redesigned 2015 Sonata here at the New York Auto Show, ushering in not only a new era of domestic stewardship for the company, but also a new, more mature design direction for its mass-market vehicles.
Though we've already seen the striking sedan in a wealth of recent photos, seeing the car in person confirmed that Hyundai has another hit on its hands. The Sonata employs the Korean automaker's new "Fluidic Sculpture 2.0" design language, which we already witnessed in the new, much lower-volume Genesis. Hyundai describes the language as being more dignified, respectable and confident. We certainly agree with that.
Gone are the swooping lines of old, which grabbed our attention on the previous generation. They've been replaced by straight edges and harder angles, most noticeably along the car's beltline. A larger, more refined grille with a wide air intake leads the car down the road. The stance is athletic, with a steeper, coupe-like roofline, quad chrome-tipped exhaust ports and horizontal lines in the rear, which give the car a planted look. The redesigned headlights are wing-like in appearance and, man, that burnt orange color is sexy.
