I don't get it. The 2.5 in our 2011 Camry, albeit with stick shift, has rarely left me wanting more power. Maybe in raw acceleration. But it only needs a downshift if I was lugging it in the first place. Not a bad engine, although, sure, more power is always nicer. On the highway I don't think I've ever needed a downshift from 6th unless if I was going 60 or less. Unfortunately my test drive in the 2012 I4 wasn't long enough, but it seemed just fine, at least with just me in it. Uninspiring, perhaps, but I didn't think it was underpowered. [But I test drive few vehicles.]
I don't plan on buying a 2013. I don't see anything to excite me. Don't care much about the loss of a full size spare, as most of my vehicles haven't had one, or required it. A new transmission, hmm, it's a Toyota but I'd hate to be among the first long term quality tester. 18 inch tires? I don't get the rush to taller rims. Styling is ok, don't mind; but I didn't care for the picture of the center stack with the NAV. Too futuristic. Slight loss of ground clearance doesn't bother me, as I don't off-road.
Personally, I wish they had geared it lower. Well, top gear overall ratio could be the same, but gear it lower in 1st. Then they could have retained a bit of the class leading towing capacity. Just hit 2k, that sounds better than the nominal 1,500lb. For me I'm rather interested in those things, and high geared transmissions I'm not interested in, even if I'm not pushing the towing limits (I have a driveway that slopes a bit, and a small camper). But I'm starting to think that a 1,500lb rating is code for "don't bother with more than 1k" so I don't see any reason for me to pursue this sort of vehicle.
I predict it'll sell well regardless.
No RAV4 (yet, maybe?)
