If I'm not mistaken the the 2013s have the newer FB series 2.5 L DOHC engine versus the older SOHC engine in the 2012s. Very small bumps in peak horsepower and torque (3 hp and 4 ft-lbs) numbers, but I've read reviews mentioning better midrange torque. I also believe the FB was design with better efficiency in mind. Anyone test drive a 2012 and 2013 back to back?

Kind of funny though. Way back in 1999 Subaru went the opposite direction on the Impreza 2.5RS (the car that started it all as far as this website goes). Back then Subaru went from a DOHC 2.5 L to the SOHC "Phase II" 2.5 L engine. The change was reported as reducing internal friction and thus resulting in a small bump in peak torque, but with much better midrange torque. The difference was noticeable to those who test drove both. Now Subaru is switching back from SOHC to DOHC.
