I do like the larger fuel tank but the difference in fuel economy may make it a wash.They have "refreshed" the design on the 2014 MY. Along with new dash layout with changeable active tft display. IIHS Top Safety Pick. AWD optional. Updated "sensus" to be touch screen with wifi. Sensus is Volvo's name for MB Command just FYI.
I have a 2012 S60 now and get just about 33 highway MPG.
Also a HUGE difference in fuel tank capacity
S60 17.8 gal
CLA 13.2 gal
Hmm here is a thought am I trying to convince myself or you guys lol
