Toyota mulling Cummins diesel for Tundra?

When Bloomberg spoke to Toyota USA Sales CEO Kazua Ohara recently, we highlighted his comments on the possible return of the Toyota Supra. However, the interview started with Ohara discussing the Tundra, and how it would take time to pinpoint and hone the pickup truck's brand image in the minds of consumers. That effort could get a boost, with a report in Edmunds saying that Toyota is "evaluating" the addition of a Cummins turbodiesel to the Tundra's engine options.
The Cummins powerplant is one of two options for the moment, the other being a hybrid powertrain. If the oil-burner got the thumbs-up, Toyota would follow the recent example of Nissan, which announced it would put a Cummins turbodiesel into its 2015 Titan. While the two Japanese companies make a closer comparison since they're both talking about Cummins applications in light-duty trucks, if it happens, it could be seen as further diluting the once-exclusive tie-up that Ram trucks has had with Cummins even though Ram has used Cummins in its heavy-duty truck.
Toyota hasn't said when it will decide on which direction to take, but either will be a move for the better in the view of segment watchers; PickupTrucks.com said the first of its top-five fixes for the Tundra would be a better engine, perhaps a diesel-electric hybrid from Toyota's Hino unit. Cummins told Edmunds it can supply a second manufacturer with the 5.0-liter diesel that Nissan will be using, so we wouldn't be surprised to see it end up in a Toyota or somewhere else.

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.

Recharge Wrap-up: BMW Next 100 video, how Nissan "tops off" battery

BMW explains the ideas behind its Vision Next 100 concept car that debuted at the Geneva Motor Show. As BMW celebrates its 100th birthday, it wants to look into the future rather than dwell on its past. This involves the digital and analog worlds working together "to create a seamless experience." Hence the "live geometry," wherein physical parts of the car move to translate digital information to the driver. The video also gets into the future of driving modes, like "Ease," for more autonomous driving, and "Boost," for when the driver wants to take control to enjoy some motoring the good, old-fashioned way. Check out the video above, and read more from Hybrid Cars. Nissan has managed to find a way to boost the range of EV batteries inspired by pouring a glass of beer. The automaker has found that after a full charge, one can wait a few minutes for subsequent "minicharges" to "top off" the battery. The voltage dips slightly, much as the foam does on a pint of beer, allowing the battery to accept some more juice. The result is an extra 0.7 percent of energy, which could mean just enough extra range to reach the next charging station. Read more from Automotive News. Hyundai has delivered its first Tucson Fuel Cell in Ontario, Canada. The lucky recipient is Joseph Cargnelli, Chief Technology Officer of Hydrogenics Corporation, a company based on hydrogen technology. The expansion into Ontario follows Hyundai's trial of six Tucson Fuel Cell vehicles in the Canadian province of British Columbia. Read more at Green Car Congress. Toyota has entered a public-private partnership to test an end-to-end hydrogen supply chain in Japan. The collaboration with the Kanagawa Prefectural Government, the municipal governments of the cities of Yokohama and Kawasaki and three private companies to create renewable hydrogen to power forklifts. It will use wind energy to electrolyze hydrogen, which will then be shipped to a factory, a vegetable and fruit market and two warehouses to be used in the fuel cell-powered vehicles. This supply chain is expected to reduce CO2 emissions by 80 percent compared to traditionally fueled forklifts. Read more from Toyota.
