Toyota says fuel cells could cost no more than diesels soon

Toyota wants to bring the cost of hydrogen fuel-cell vehicles down to something along the lines of a diesel vehicle's price tag. It just might take until the alliterative year of 2022 to hit that target. Such is the challenge of modern engineering. Fuel-cell vehicle costs may eventually approach diesel vehicle costs because of the relatively expensive process of both making a diesel engine and including it with particulate filters and other treatments required to reduce the soot once associated with such engines, Automotive News says, citing comments from Toyota executive Katsuhiko Hirose. And, while engineers initially estimated that fuel cells and diesels would reach price parity in about 15 years, Hirose said Toyota higher ups weren't satisfied with that answer and think the timeframe could be cut in half. The Japanese automaker in January said it would ramp up the manufacturing rate of its first production fuel-cell vehicle, the Mirai, to about 700 units this year and to 2,000 vehicles for 2016. Later this year, Toyota will start selling the Mirai in the US for either $57,500 as a purchase or $499-a-month lease, and both options come with free hydrogen. Who can say that about diesel fuel?

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.

Scion was Toyota's lost generation

Toyota's top North American leader was succinct in explaining the reasons for killing Scion. "It's the right decision at the right time," Jim Lentz said. It's hard to disagree. In a strong market that saw 17.5 million sales last year, Scion volume dipped three percent. Its product lineup has withered for years, which is always a telltale sign a brand doesn't have the full support of its owner. Though enthusiasts love the FR-S sports car, it's the fruit of a joint project with Subaru that also produced the BRZ. Scion's coolest car has a twin sold by one of its rivals. After the FR-S launched in 2012, Scion got nothing – squat – in the way of new products until the iA and iM arrived late last year, IHS senior analyst Stephanie Brinley noted. "[Scion] was not successful in building a visual brand identity or product personality," she said. Lentz, Scion's first vice president and now CEO of Toyota's North American division, admitted the market has changed. "Younger customers have a different mindset," he said. In the early oughts, a brand that catered to a youthful demographic made some sense, and this is one front where Toyota can declare victory. Seventy percent of Scion's buyers were new to Toyota, and the average age was 36 years old. The problem is, not enough of them buy Scions anymore. Scion hit a highwater sales mark of 173,034 vehicles in 2006 and hasn't come close to reaching that since. The recession hurt Scion, too. It bottomed out in 2010 with just 45,678 sales, a time when the rest of the industry was beginning to recover. There was a brief uptick (73,507) in 2012, but Scion failed to capitalize on that momentum and sales fell for three more years. Toyota is calling Scion's pending death a "transition" back to the main company. Sure, most of the cars will be rebadged Toyotas, like the FR-S, iA, and iM. The C-HR, an attractive future crossover that would have given Scion a boost, will go into production as a Toyota. But make no mistake: This is a failure. Toyota is closing a brand in the same way General Motors scrapped Oldsmobile, Ford shuttered Mercury, and Chrysler dropped Plymouth. Those brands languished for years. Toyota moved quicker to put the fork in Scion, which prevented it from becoming a long-term drain on the parent company. Lentz was dead on. It's the right time.
