Except for the charge timer issue, we are absolutely loving the RAV after our first week. I'll lay out a few of my thoughts for anyone who is trying to make a decision on which car to buy, and if you live in California where the RAV is sold you have more choices than most.
First, It's a blast to drive, and the GOM is reasonably accurate. It doesn't tell you it will travel 112 miles and then only take you 70. My 80% charge consistently reads around 100 miles, and when my wife returns from her 26 mile commute, it reads right around 75. That alone makes this car priceless.
I thought I would be worried about the lack of a QC on the car, but honestly I don't anticipate it ever being an issue. If we think we need to drive it more we can charge to 100%, but I think the only time we'll ever do that is if we decide to drive to Tucson. That extra range really has alleviated a lot of stress and removed the more careful planning we needed to do with the Leaf. I think 100 miles is really the sweet spot, and everything above that number is icing, so I think a bigger battery would be wasteful for us since we don't take many long driving trips.
The Leaf is a much smoother ride, with the RAV driving much more like the truck that it is. A good bit of road noise from the tires, so the cabin isn't the same pristine driving experience as the Leaf. Tony complains of the whine from the motor in the RAV, as have others, but I haven't noticed this. The bumpiness of the ride has its charm and reminds me a little of driving my best friend's old FJ40 as it bounces around on the bigger tires, but unlike the FJ it feels super-speedy for such a big ride. I rarely switch into sport mode except for merging into traffic because it's too tempting to fly.
As you probably know, it has a 10kW charger, which is the good part. Unfortunately, the charge door is way back on the car, meaning I have to back it in at all the Blink chargers with their ridiculously short cords, and 99% of the public chargers in PHX are Blink. The good part is that we don't need to charge in public much, except with my Volt, which I charge about 2x week outside of the house. As I mentioned earlier, there are crazy issues with the charge timer, so you really have to start your charge before you go to bed if you want it to be charged the next morning. I'm certain this is a software fix that will hopefully be fixed soon. It's often very noisy when it's charging, which I assume is the TMS doing its work, but I'll be the last person to complain about a TMS making noise, especially when it's 115 outside.
Visibility is excellent, although the Leaf is a little better, IMHO. Way better than the Volt, which is like driving a submarine. A periscope would be a great improvement for backing up, and it could have easily been called the Chevy Blindspot instead of Volt. I wish the RAV backup camera had guidelines and metered markings, but it's a minor comlaint.
As for cargo space, of course the RAV wins by a landslide. Back seats fold flat, giving a ton of room for those outdoor chairs I need to buy tomorrow. The Leaf's cargo capacity isn't bad, and the Volt is good for groceries, but they really pale in comparison. There's also a nice, generously-sized compartment under the rear deck where you can store things you don't want thieves to see, like computers, your charge cord, etc. It's very handy.
I find the seats and driving position most comfortable in the Volt, and I like the more firm, supportive padding in the seats. To my eye the RAV seats look cheap, but they are comfortable enough, so no real complaints. I'm glad it's the most comfortable, since it's the car we would take on trips, and for the same reason I'm glad it has a great sounding stereo. Both our Leaf and the RAV had/have light colored interiors, and I'm not a fan. I'm glad the Leaf finally offers a darker interior color, and I appreciate the dark interior on my Volt, since it's the car my son rides in most days.
The Leaf sound system is better then the RAV (although the system in my Volt seems better still), and the Bluetooth calling is MUCH cleaner in the Leaf. The Volt Bluetooth, at least on the receiving end, is like talking to a Burger King drive thru, and two people have asked I not call them on it any more, but the sound is good enough inside the car. I plan to take it to Chevy and have them check this out. Bluetooth in the Toyota isn't bad, but isn't as clean as the Leaf. If you do a lot of business on the way to and from work, then this could be a serious consideration.
Speaking of noise, the RAV emits the most ear-spliiting, horrific noise when you shift into reverse. It's terrible, and I think it only makes noise inside the cabin, not out like the Leaf. You can apparently take it into a dealer and they can make it stop, so that's on my list. The Volt has options for almost everything, so you are able to rid yourself of all the annoying noises it makes (if they annoy you!).
The RAV's center screen, while generous in size, seems to be a step down from the Leaf and doesn't play nice with my polarized sunglasses, and I don't like the interface as much, but I do like how uncluttered the driver interface feels. The Leaf does a good job with this too, and I like that aesthetic. The Volt is an information dump, which is useful at times, but I feel like the interior is too cluttered with the plasticky, cheap-feeling touch-sensitive center console and the myriad number of buttons. One thing I do love about the Volt interface is the little zen ball on the driver's display, which you try to keep centered by driving efficiently. I like that much better than creating phony trees, since driving any kind of car isn't doing the environment a great favor. I do feel more centered when I drive efficiently, instead of speeding through traffic and stressing myself out.
The navigation feels better in the RAV, and seems to have more POI's in its database. It also doesn't screw with you when the autofill completes things and you click on the wrong address by accident. I hated that about the Leaf. The Toyota also gives you several route options on-screen, which I like, although I rarely use navigation since I know the city pretty well. I only have the OnStar nav in my car, so I can't really make an educated statement about the Volt's nav.
One place where the Leaf really shines is that both my wife and I felt like there was no learning curve, and almost everything about it felt intuitive. That's not been as true with the RAV, and especially not true with the Volt. I'm finally comfortable with all the Volt's controls, but only after a couple of weeks fiddling with everything, while it took me about three days to get comfortable with the RAV.
Those are my observations for now. I'll try to edit it more if I think of other things, but I just want to help others make an educated decision. All three cars are great in their own ways, so it really comes down to needs, location, and personal taste.
