Ok so I have seen two '13 Outbacks, both 2.5 models, one looked to be a white premium and the other was the cool BBP with SAP model. Anyway I know it's crazy I notice minor details like this when I see other Outbacks but when did they change the rear differential housing to a " finned " casing?
The one on my '11, 2.5i CVT is smooth aluminum looking. The two cars I've seen had little fins or ribs for additional cooling? Useually this is seen on higher end performance cars fitted with a limited slip differential to aid in cooling the fluid.
Example, my '13 WRX has the smooth diff housing like my Outback, understandable as both are open differentials. However the finned unit that I've seen so far on the '13 Outbacks looks like the same finned diff housing on the WRX- STi model??
Does anyone know when they switched? or what exact models of Outback get this differential? I've seen '13 Outbacks with the smooth one too like my '11 Outback so it appears there is no rhyme or reason for it, but I'm sure there is. Purhaps manual Outbacks get it? But I didn't think you could get manual and BBP/SAP either? I thought you could only spec a manual trans up to a premium model so who knows. Not a big deal just a curious car/ techy nerd wanting to know exactly.
