Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

Toyota settles first wrongful death suit related to unintended acceleration

Toyota's sales seem to have rebounded from the unintended acceleration issues from 2009 and 2010, but the automaker is far from done dealing with this situation. Following a settlement worth up to $1.4 billion for economic loss to affected vehicle owners, Toyota has settled rather than going to trial in a wrongful death lawsuit stemming from an accident in Utah in 2010 that left two passengers dead. This isn't the first case in which Toyota has settled, but it was the first among a consolidated group of cases being held in Santa Ana, CA.
According to The Detroit News, this case was scheduled to take place next month, and it was for a November 2010 incident in which Paul Van Alfen and Charlene James Lloyd were killed in a Camry when, based on findings by the Utah Highway Patrol, the accelerator got stuck causing the car to speed out of control and hit a wall; the terms of the settlement were not announced.
The article says that while Toyota will settle on some cases, it doesn't plan on settling on all of them as it still wants to be able to "defend [its] product at trial." This will probably be the case in suits claiming that software for the drive-by-wire accelerator was the cause of an accident in a Toyota or Lexus vehicle. The question of whether or not the electronic accelerator played any role in this problem has been a hot-button topic since the beginning. Toyota has issued recalls in the past to attempt to prevent unintended acceleration caused by trapped floor mats and faulty accelerator pedals, but it also says driver error was to blame in some instances.

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.
