We previously owned a 2011 Sorrento EX V6 AWD. I thought moving to the 2012 EX AWD with a 4 cylinder would help with gas mileage. However, it didn't turn out that way. While we did get some improvement (apprx. 3mpg for both city and highway) it was not significant enough to give up the 6 cylinder.
Fortunately for us we got such a good trade in value on the previous Kia, that we actually lowered our payment. The cars were both EX AWD models. The 2011 had a sunroof but no navigation system or premium sound. The 2012 does not have a sunroof but does have the premium sound and navigation system.
Overall, we prefer the 2012. We think it rides smoother with a less jarring ride over road bumps.
The 7 passenger seating, fold away mirrors, drivers seat memory. Good performance from the 4cylinder.
The ride can still be a little harsh at times. Gas mileage!
