Toyota and Tesla May Work Together Again

cartechboy writes: Tesla and Toyota have already worked together a few times. The factory in which Tesla builds the electric Model S? It bought that from Toyota. The Toyota RAV4 EV? The battery and software tuning was done by Tesla. Now it sounds like Tesla and Toyota might have another significant project in the pipeline in the next two or three years. Tesla CEO Musk said such a project could be "on a much higher volume level" than the firm's last project with Toyota, the RAV4 EV. Toyota currently has a 2.4 percent stake in Tesla Motors and has sold 2,130 RAV4 EVs through August. For its part, Toyota has no comment regarding Musk's statements about the future project. Given Toyota's stance on electric cars, Musk's comment is a bit confusing. So what exactly will this joint project be?

    Because pure electric cars are new technology that are cool and interesting to read about. Because, for the moment, it still reads like an underdog story(not that I actually buy into that being true). Because are we really that interested in what, say, Microsoft is up to now?

  3. My guess:Series Hybrid + recharge tech licensing by Isca · · Score: 4, Interesting

    The current Priuses and other Toyota offerings are parallel hybrids. That is, they have transmissions that directly drive the wheels using the ICE (Internal Combustion Engine).

    In a series hybrid, each wheel has it's own motor, and the ICE engine runs at a steady speed that is very efficient to generate electricity that is then used to recharge the batteries that are fed to the electric motors.

    A second part of my guess is that Toyota is licensing the recharging technology from Tesla, so that they can use the supercharger network as well. This way they can have a vehicle that can run 100% off of electricity only, but have a ICE engine that is available at any time to back that up (faster refueling, can go anywhere there is a gas station, etc.)

      Agreed.

      And the Plug-in-Prius can't even drive 100% electric at freeway speeds.

      The "plug-in" part really is a joke on the Prius. It's definitely not worth the extra $5k over the regular Prius.

      And the Plug-in-Prius can't even drive 100% electric at freeway speeds.

      I frequently drive a plug-in Prius at 65mph in pure EV mode. It's really no big deal (unless you're one of those people who insist on stopping at the top of the on-ramp, so you have to stand on the accelerator to get up to speed.) I can hit 70 or more on a downhill with a tailwind :) .

      The "plug-in" part really is a joke on the Prius. It's definitely not worth the extra $5k over the regular Prius.

      Unless 90% of your driving is under ten miles round trip, and you don't like to rent cars in order to drive more than the 80 mile range you'd get from a 2014 Leaf, in which case the PiP pays for itself.

      FYI, I drive a Leaf and my husband drives a Prius.

      The Leaf is a great car if you get the 6.6 KWH on-board charger and a level 2 EVSE ($600 minimum). If you have only the level 1 EVSE and the lame charger, you're talking about a vehicle that literally spends far more of its time on the charger than on the road. Not worth the price for most people.

      But in any case you can't just buy a car without analyzing your needs - not even a gas car. It's even more important when you buy an EV or plug-in. You have to know what you'll be doing with it, and how long you plan to keep driving it. They aren't for everyone yet, although Tesla is working on changing that.

      My spouse drives a Leaf and gets three days driving from one charge; I drive the plug-in Prius and charge every day - sometimes two or three times a day. In firewood cutting season I spend more money on gas for my chain saws than I do for my car.

      One thing that does totally suck about both cars is the lack of a spare tire. This offends me so much I am trying to figure out how to mount spares on the rear bumpers! The regular Prius has a spare.

  6. What stance? by drinkypoo · · Score: 2

    Given Toyota's stance on electric cars, Musk's comment is a bit confusing.

    So I followed the relevant link in TFS and the only substance there is the following: Toyota's Global R&D Chief Mitsuhisa Kato [...] said: "The cruising distance is so short for [electric cars], and the charging time is so long ... At the current level of technology, somebody needs to invent a Nobel Prize-winning type battery." Somebody needs to for what? Certainly not for Toyota to sell an EV, because they've done that already. But I'm not really clear on what Toyota's stance on EVs is, except that the battery technology is not where they'd like to see it. That's everyone's stance on EVs.

    Here's my prediction: Either Tesla is going to provide the powertrain for another Toyota EV, possibly a RAV4, or Toyota is going to provide the car (perhaps sans plastics and fenders) for Tesla's upcoming cheaper car. I'd like to see such a car made of Aluminum, but Tesla has hinted that the next car or two won't be made of so much of it, and Toyota is generally allergic to it for all but top-end models.

    Parallel = electric motor and gas motor are both connected to the drive train.
    Series = only the electric motor is connected to the drive train.
    Prius is a "power split" or a "series parallel" hybrid, which is a bullshit term that means "we are special and not just a parallel hybrid"

    In the modern colloquial terminology, slang usage seems to to be
    "Series" = "range extended electric vehicle" or "generater in the trunk"
    "Parallel" = "doesn't work without gasoline"

    In general, people don't care HOW a series/parallel/power split/monkeyass hybrid works... they just care about the "doesn't work without gasoline" part, which is the tough pill to swallow with modern "totally not parallel" hybrids.

    Pretty sure those runaways were caused by morons who put their floormats over the accelerator, not software.

    Pretty sure they weren't (at least, not all of them).

    Having spent more than 18 months going in and out of the secure room to study Toyota's code, Michael Barr, CTO of the Barr Group, put together an 800-page report analyzing the 2005 Camry L4's software. On the witness stand, he walked a jury step by step through what the experts discovered in their source-code review.

    ...

    Barr testified that the source-code review indicated "both that task could die by the memory corruption, and that also that one of side effects of that would be that this -- for example, that task died, that many of fail safes would be disabled." But is it possible to prove that the experts' discoveries in that cloak-and-dagger source-code room would manifest themselves in a moving vehicle? How do we know how a car might react to malfunctions or an outright failure in Task X?

    ...

    However, we have confirmed in other vehicle testing that I'll talk about later, that if the incident begins with the peddle, [sic] brake peddle [sic] pressed at all, even lightly then the unintended acceleration will continue, potentially, forever unless the driver tries the risky thing of letting go of the brake while the car is driving away with him.
