Hyundai Nexo revealed at CES: Hydrogen SUV finally gets a name, more photos

Hyundai Nexo, that's the name of the fuel-cell electric vehicle to succeed the Tucson FCEV. Built on a dedicated platform instead of using a converted ICE architecture, as the Tucson did, the Nexo packs a lighter, more compact hydrogen powertrain and a more powerful electric motor to deliver improved performance everywhere. The Nexo also plays a key role in Hyundai's "Hydrogen Life Vision," which aims at integrating hydrogen as a home energy source. The power density of the Nexo's stack increases by 50 percent, and overall system efficiency goes up 5.1 percent. The smaller engine contains fewer moving parts, and even the hydrogen tanks are 36 pounds lighter than those in the Tucson FCEV. View 11 Photos The Tucson FCEV uses a 100-kW electric motor that provides 221-pound-feet of torque, and after the 90-second preparation and stack heating time on startup, the Tucson accelerates from zero to 60 miles per hour in 12.5 seconds. The Tucson's two storage tanks held 140 liters of hydrogen (37 gallons) that could provide about 295 miles of range and an EPA rating of 50 mpge. The Nexo uses a 120-kW motor with 291 lb-ft, is ready to go in 30 seconds after starting, and accelerates to 60 mph in 9.9 seconds. The new FCEV's three storage tanks hold 156 liters of hydrogen (42 gallons), which Hyundai says are good for more than 350 miles on the EPA test cycle. In a real-world run from Los Angeles to Las Vegas, Hyundai said the Nexo returned a 360-mile range and 57 mpge. Refilling the 700-bar system will take five minutes. The Nexo will introduce some of the carmaker's new technology, too. Lane Following Assist keeps the Nexo in the center of its lane in the city and on the highway, and recognizes road edges when lane markings aren't clear. Blind-spot View Monitor displays an image of either side of the vehicle when the driver plans to change lanes. The Nexo parks itself autonomously, and returns, with Remote Smart Parking Assistant Hyundai envisions owners of this second-generation FCEV beginning to use the Nexo as an integral part of their lives, not merely as an appliance. At the Consumer Electronics Show, Hyundai will have the Nexo hooked up and providing power to a demo household as part of the automaker's "Hydrogen Life Vision." The carmaker's also got plans for using the Nexo's "pure water to grow vegetation" (water and water vapor are the only emissions byproduct of FCEVs).

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.

First 2015 Hyundai Sonata ad surfaces

The new Hyundai Sonata just made its debut at the 2014 New York Auto Show, but it's already begun making its slow march towards dealers, meaning it's about time we start seeing ads for the new family sedan on the TV and internet. This 62-second spot is one of the first.
The ad places a particular focus on styling, and what great design really is. There's also a glimpse at the super-cool gesture control that's baked into the Sonata's infotainment screen. We'll admit, we're pretty geeked to give this feature a full test once we finally drive the all-new sedan.
As for when that will be, with the car set for an arrival at dealers this summer, we're hoping to have a full write-up on the 2015 Sonata soon. Until then, scroll down for the full ad from Hyundai.
