Hi Rokeby and Clev,

I am thinking Toe-in too. In that the 2010 rolls and rolls below 40 mph, in comparison to the 2006. At the higher speeds, the tires toe out, and if the toe-in setting is dead on zero, this would create scuffing friction on the tires.

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....
