Not much per se, it is really the same as the '08.

We just trades our 1998 Camry4 cyl auto, for a 2009 4cyl auto and I'am VERY disapointed. The 09 eng noise the trans shifts at odd times, if you accelerate from 65 to 75 it drops one gear and increases very slowly...more gas pedle makes it down shift and start to screem! downshifting while coasting downhill down hill?? and the gas milage isn't as good as the 98!. The 09 isn't even close to the 1998 I traded. What a mistake this was.
