The CC was built with the underpinnings of the (2006-2010) B6 Passat underneath, but with different/stylish sheet metal on top
It's the same 2.0T TSI that was in the 2008.5+ MK5 & the MK6 GTI's and the Tiguan, etc. (same engine mods)
2009 had a traditional automatic with the 2.0T, while 2010+ had a DSG paired with it
It was up until 2015 or 2016 (?) that you could get a manual trans too.
In the highest trims, you could get the 3.6 V6 with an automatic & 4motion. FWD with the 3.6 was rarer and offered in limited years.
It's a nice/solid car, but the weak point is the TSI engine and it's known issues. If you keep up on the maintenance though, it shouldn't be an issue.
Kinda pricey new, but VERY nice inside for the money...while being unique.
Their values, used, have plummeted though
