I test drove one tonight. Great performance, easy to spin the wheels if you are not careful, especially around a corner. The "sport" mode definitely gives you more torque, but the regular mode is good enough for nearly all occasions I would think -- still more power than the Leaf. It does drive like and SUV -- this is not a sports car by any stretch. I have never owned an SUV, and I was a bit surprised by the bounciness on the local freeway (280 near Mountain View CA). It drives more like a refined truck than a car, IMHO, on the freeway. On city roads, it has a decent amount of feedback to the steering wheel for an SUV. Nice smooth driving. The seats are decent, but have the typical problem of the cushion being too short for people with long thighs. The interior is definitely superior to that of our Leaf, and the entertainment system seems a bit more advanced. Very roomy, front and back and cargo.
The "B" mode gives you stronger regen than "D", but it's not nearly as strong as in the Tesla Model S or the Honda Fit EV. I think that's too bad, since you could avoid touching the brake at all in most cases. Basically Toyota doesn't want people to think this is that much different than a gas car, even though they might actually sell more of them if they did. I noticed that in B mode, the regen takes about 400ms to kick in after letting off the accelerator -- a bit annoying.
I parked it and got out before turning it off, and I was surprised at how much noise was coming from under the hood! Must have been the fans cooling the motor and battery. Not used to that with the Leaf. It's a bit noisy when charging -- some odd clicking sound coming from under the car. I assume it was normal, but again, never noticed anything like that with the Leaf. Charged fine with our Blink charger at 30A.
We're definitely thinking about it. I'm also tempted by the Fit EV, even given the extremely different set of tradeoffs.
I'll add more as I think of things.
