    The fact that it isn't available is one reason I haven't ordered one. If they hadn't screwed up the packages, the interior storage and had provided this as an option, I'd have one already. As it is, I may wait a while, including possibly several years.

    They may have decided to not bring it here due to supply problems with the parts, or it could be the managers here were unsure it would sell at the prices they would have to charge (I suspect it would up the price approx. $3000, maybe more). They can always reconsider later and try it here. The only downside for Toyota is they would have to stock the parts for, what, 7 years? If it didn't sell well enough to continue offering it that is. It could even be that it would lower the mileage average over the models enough the nay-sayers might have had too much ammo., or even that they had enough on their plate with just the new car and the models they brought. Again, maybe they will reconsider it later. Northern States and Canada would probably be able to sell them easily.

    I'm not so sure I would want one. It needs ground clearance to operate here in winter, and it doesn't have that.

    I'm not so sure the ground clearance is as necessary, at least for some markets. In Toronto we tend to have lighter snowfalls and milder weather in the winter compared to some other provinces, but nonetheless ice is a common problem. What ends up happening not infrequently is that there will be some snow and then a melt which then freezes over into a sheet of ice, which then gets covered up in a few cm of snow. Given that I live at the bottom of a hill, this wreaks havoc with my FWD Prius when trying to climb up the hill. I can usually do it, but very slowly, and if I have to stop for any reason then it's a lost cause. I sometimes can't get started again because there isn't enough traction to move without the previous momentum I had.

    An AWD "light" would be perfect for this. Mind you, that wouldn't be worth US$3000 to me either. We ordered it for the RAV4, but the FWD version doesn't even exist in the hybrid models anyway. But looking at the XLE non-hybrid models, the premium here is CAD$2150 for AWD (mechanical, not electric motors).

    In the US, for the XLE, the AWD premium is US$1400, and for the Limited it is also $1400.

    So, would I pay US$3000 for AWD in a Prius? Definitely no.
    But would I pay US$1400 for AWD in a Prius? Probably yes, at least if it's relatively decent.

    Note: I'd prefer to keep the spare tire though, which would prove problematic.

    I would as well.

    Thanks for posting that video. A subsequent related video is also helpful:



    Gas engine: 142 Nm at 3600 rpm (106 ft-lb)
    Front electric motor: 163 Nm (120 ft-lb)
    Rear electric motor: 55 Nm (41 ft-lb)

    So 41 ft lb of torque and 7 HP. added in the rear.

    The original Beetle had 50 ft lbs in the rear, and no other source of power. 24 HP

    Ok, but then again that Beetle only weighed 750 kg. That's roughly half the weight of the Prius AWD (1460 kg).

    40.6lb-ft of torque with a reduction ratio of 10.487

    That means you get 40.6*10.487 = 426ft-lbs of torque to split between the rear wheels.

    Since the radius of the tires is almost exactly 1 foot, that means 426 pounds of thrust at maximum torque.

    That's where I got the thrust number.

    Analyzing this video, I timed from first motion to when the front license plate reached the edge of the frame.

    2WD: 58 frames
    4WD: 44 frames

    4WD was 32% faster.

    The first video is funny. Driving a car on teflon sheet!
