2015 Hyundai Genesis 5.0 First Drive [w/video]

The original Hyundai Genesis was something of a mixed bag. A great first effort, no doubt, but as with any, well, genesis, there were weak points – the infotainment system and some interior materials, for example. In creating its second-generation model, Hyundai paid plenty of attention to these shortcomings while wisely deciding to retain the most notable of the original model's strengths: its 5.0-liter V8. The 420-horsepower rocket from the former Genesis R-Spec has once again been named the top-flight engine for this updated, 2015 model. Hyundai has comprehensively overhauled its first rear-wheel drive sedan, and while it might use an older – but impressive – engine, the 5.0-liter V8 isn't nearly as big of a story this time around. That's because it's now wrapped inside a far better package, as we found during a week behind the wheel. Hyundai's stylists have matured the Genny, opting for significantly more standout sheet metal in this new iteration. The old car featured a more traditional three-box shape, while the second-gen car is more open about its rear-drive layout, featuring a long hood and a short rear deck that feeds right into an aggressively raked rear window. The upright front fascia, with its broad, crisply styled grille and almond-shaped headlamps is clean and fashionable while still coming off as sort of conservative. Around back, Hyundai maintained some semblance of its old fluidic design, with sweeping, wraparound taillamps, while the V8 model's bumper is home to sporty, staggered quad exhausts. That said, the updates to the exterior are overshadowed by the comprehensive overhaul found in the cabin. The Genesis finally has an interior befitting of its price tag, thanks in large part to the swath of natural-looking matte wood trim on the dash, complemented by aluminum accents. The upper and lower dashes are finished in plastic, but its quality is no better or worse than what you'd find in a German competitor. However, while the cabin certainly feels much better than the last-gen model, there are still a few shortcomings. The "ultra premium" leather is standard on the 5.0's wide, supportive seats, and while it feels very, very nice, we did notice that even with fewer than 8,000 miles on the clock, a regular parade of denim-clad auto journalists has already started to stain the driver's side bottom cushion – something we noted during our year-long test of Hyundai's larger Equus.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

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.
