I took delivery of my 06 2WD Highlander in mid-July. I have kept records of fuel and mileage, with comments on types of driving. When I have used more than 10 tanks I'll post some summary info. here, if people are interested. It takes a little while to optimize the driving techniques, and the car still has a bit of breaking in to do, I imagine.

I have an interest in PHEV (p;ug-in hybrid conversion), as soon to be offered (2006) for the Prius II by EDrive systems (http://www.edrivesystems.com/), and first developed by Felix Kramer and calcars (http://www.calcars.org/vehicles.html). I am ready when there is a conversion kit for the Highlander!

I am in Dallas, and there aren't that many hybrids here, but there are a few.

Anyone have any latest information on Toyota's ideas as to more prominent badging for the HiHy? I looked under the hood at the plastic cover for the auxiliary (i.e., battery) cooling system, and there's a b/w stick-on label (thin aluminum, or otherwise metallic?) that says "Hybrid Synergy System", but with no color and no little logo design. I'm considering peeling it carefully off and applying it to the back for greater prominence. I asked my dealer's parts department about buying just the sticker, but you have to buy the whole cover for $190. ! Anyone have a source for an after-market basdge, or is anyone making one, or does anyone want to go into the business (for love, obviously, not money)? Let me know.

I would enjoy sharing information on optimal driving techniques. The best thing that could happen here in Texas is for the summer to end! I want to see what mileage I get without 100+ degrees to contend with, and the A/C required to get to work without being drenched ("I'm not sweating - - that's a 'sheen'!").
