Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.

Automakers not currently promoting EVs are probably doomed

Okay, let's be honest. The sky isn't falling – gas prices are. In fact, some experts say that prices at the pump will remain depressed for the next decade. Consumers have flocked to SUVs and CUVs, reversing the upward trend in US fuel economy seen over the last several years. A sudden push into electric vehicles seems ridiculous when gas guzzlers are selling so well. Make hay while the sun shines, right? A quick glance at some facts and figures provides evidence that the automakers currently doubling down on internal combustion probably have some rocky years ahead of them. Fiat Chrysler Automobiles is a prime example of a volume manufacturer devoted to incremental gains for existing powertrains. Though FCA will kill off some of its more fuel-efficient models, part of its business plan involves replacing four- and five-speed transmissions with eight- and nine-speed units, yielding a fuel efficiency boost in the vicinity of ten percent over the next few years. Recent developments by battery startups have led some to suggest that efficiency and capacity could increase by over 100 percent in the same time. Research and development budgets paint a grim picture for old guard companies like Fiat Chrysler: In 2014, FCA spent about $1,026 per car sold on R&D, compared with about $24,783 per car sold for Tesla. To be fair, FCA can't be expected to match Tesla's efforts when its entry-level cars list for little more than half that much. But even more so than R&D, the area in which newcomers like Tesla have the industry licked is infrastructure. We often forget that our vehicles are mostly useless metal boxes without access to the network of fueling stations that keep them rolling. While EVs can always be plugged in at home, their proliferation depends on a similar network of charging stations that can allow for prolonged travel. Tesla already has 597 of its 480-volt Superchargers installed worldwide, and that figure will continue to rise. Porsche has also proposed a new 800-volt "Turbo Charging Station" to support the production version of its Mission E concept, and perhaps other VW Auto Group vehicles. As EVs grow in popularity, investment in these proprietary networks will pay off — who would buy a Chevy if the gas stations served only Ford owners? If anyone missed the importance of infrastructure, it's Toyota.

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.
