The tighter bearings and non-broken in tires would impact the slow speed rolling too. If the car is rolling better at slow speeds, then other than the toe-in issue, its gotta be aero-dynamics.
I have two long slow hills on one of my routes. On the really long hill, I am at 40 mph at the top, and 36 at the bottom 1 1/2 miles later. Both cars do this exactly. On the other hill I crest at 33 mph, and at the base I am doing 35 about 1/2 mile later. Again both cars do this the same.
Slow-Speed down hill coasting wise this car is very very similar to the 2006. In the flats, I think it coasts a little better than the 2006, but I guess that is kinda subjective....

Definitely keep a close eye on your front tires for excess wear on the outer edges. My 2006 Corolla ate up the front tires in 13k miles, and I bought it with 6 miles on the odometer.
After the typical dealer mumbo jumbo, Toyota replaced the tires for free and actually had to tweak the unibody in the rear to get the rear axle properly aligned.
If you really want to know get a reputable (non Toyota) shop to do a thorough 4 wheel alignment check. Be careful of statements like the toe is in specs, when the total toe has a spec beyond the individual wheels. Also if you have the alignment adjusted, tell them to try for minimum total toe at all 4 wheels. Not sure it that is adjustable at the rear wheels, but if so go for minimum total of all wheels.
