Were there any changes between the two years?

 

I think page 2 from the 2010 document answers your question. To summarize, the few differences are mostly in model, feature package, and color availability. The only mechanical difference mentioned in this document is a 1.2 quart increase in the coolant capacity. Not sure if this means a larger radiator or ???

Interesting to compare the 2010 changes with the equivalent 2009 document.

Hope that helps.
