Yes, dumb is the key word here. It's been one of my top complaints about the ActiveE as well. But alas, one will resign to this design travesty eventually. Image
I seriously think I would just move it to the nose. I could have two ports.

Nice review, Tony. Given the amount of time it took Toyota/Tesla to whip this thing together, imagine what they could do with a normal product development cycle.

I wish they'd stick the drivetrain in the Camry or something - though I imagine it's easier to squeeze the batteries into the RAV4 without compromising road clearance.

How much did Mossy Toyota charge you for the rental?

In that case, I think you might want to watch this. Good looking car otherwise!

If my source is correct, it was Tesla's suggestion to go with a RAV4 chassis for this EV, and they evaluated all cars/platforms in Toyota's portfolio.

Über secret rolling hill test results : 78mph peak vice 81mph for LEAF. Unfortunately, we're not making a completely valid test, since the Rav4 weighs more, but it is surprisingly close. With a 1 foot square box on top of LEAF, it went 73mph. Toyota says 0.30 Cd, and Nissan says 0.29 Cd for LEAF (but with much smaller flat plate area).

Range will be greater in Model S with the same 40kWh battery pack and 0.24 Cd.
In LEAF I am now getting 5.0-5.2 m/kWh quite often on freeway RT doing 54-58 mph.

3.6 m/kWh with charging at 6.6 kW L2 = 24 miles per hour of charge - about 50% better than 2011/2012 LEAF.
If your L2 is actually delivering 208V (quite common, I believe), charge rate would be a little lower.

With RAV4 EV I would hope to get at least 4.0 m/kWh, but it sounds like I might have to drive less than 54 mph to achieve this. As you say, higher frontal area is main problem on level ground. For hill climbing one would also have to derate more for heavier weight.

What is the usable battery capacity in kWh in both Normal and Sport mode ?

I picked up the RAV4 early this morning from Roseville Toyota. It's a blast! :)

I put it in B and sport mode for the drive back to work. Amazing. Broke traction numerous times, up to what seemed 30mph. The roads were a bit slick, but still... this thing has a LOT of torque. Tony's right, it's downright nutty. You can get yourself in to trouble pretty easily. Push sport button, win ticket. ;)

The regen in B mode seems stronger than the leaf, but not substantially so. The application is different, with an initial strong negative torque as you lift off the throttle but you still need to use the brakes to come to a complete stop. Will do some power hill climbing (and regen-ing) tomorrow.

I tested the hauling capability by moving a couch. The timing was perfect, as I had recently gotten a good deal on one from a coworker. It luckily splits in two sections, and the back seats in the RAV4 go down flat. Seemed similar to the cargo capabilities of my old 2002 Honda CR-V.

More to follow. Haven't even fiddled much with the nav.

Oh and my efficiency for the last few trips was 2.8 mi/kWh. :shock: :?

Not to worry! The dash in my ActiveE proudly displays 3.0 miles per kWh. It just takes some getting used to :lol:

Ok, here it is. 100% "extended" (range charge in Tesla-speak) with 130.1 miles driven. This is "Very Low Battery", and still shows one segment of the 16 Fuel Bar segments. It probably still had a few miles left in it:

The 240 volt estimate is at 10kW (40 amps). Only the Tesla Roadster chargers in public can do this (Clipper Creek CS100). So, for lowly 6.6kW (30 amps), add a few hours:

Very cool, Tony! Did that 130 miles include your trip to Julian? How fast were you driving?

Very cool that you've handily beat the EPA rated range, including some freeway driving.

You sure about that? Typical Toyota Smart Key System behavior is that the interior lights turn on as you approach it w/the smart key. Only when you touch the rear of the door handles do the doors unlock, confirmed by a two beeps. Pushing the black button locks the doors and that is its ONLY action. On newer Toyotas w/SKS (like the '10+ Prius), the black button has been replaced by two ridges that you can push on/squeeze on.

On Nissans w/smart key (Intelligent Key in Nissan parlance), the black button serves both lock and unlock functions. I dislike that.

Yep. 4000 feet up and down, plus some time at 85mph on the freeway (it has to be in "sport" mode to hit over 100mph, which I forgot at the time).

I just drove "normal" the rest of the time, with the A/C on "ECO Hi". Here's a picture of the economy going up to Julian (left column) and coming back:
