It's interesting how Toyota took so much different an approach than Honda did with the Accord. Smaller gas engine, far better city fuel economy, but roughly the same highway fuel econ.
If this car manages mid-thirties in typical driving that will be quite an achievement. The much more powerful, heavier Highlander seems to get about 25 in real-world mixed driving, so this should be doable.
The Honda hasn't sold very well, and a dealer near me said they'd like to deal on the HH because they'd had a couple on the lot for a while, but I think the Camry will do better because of the higher EPA numbers. If not, then this will prove that a hybrid that looks like a normal car simply isn't in much demand. Many Prius buyers probably like how the whole car seems different and that everyone can tell they're driving a hybrid.
