The headlights are a little better, by being less overwhelming bling... but don't fix the car's aesthetic boringness compared to my BL Legacy sedan
The wheels on the Outback are more striking than anything... Three bold polished spokes, in front of three other background thin spokes... Not sure if I like the design... but I can't say it is boring like the BRZ and Impreza OE wheels lately.
Come to think of it... I wonder what those 3-over-3 Outback wheels would look like on a BRZ... The BRZ wheels are way too busy looking. 06-07 WRX 7-spoke wheels would also look good on there, and probably Subaru's best looking OE 5x100 wheels in a while. But it is entirely more likely to put aftermarket staggered width wheels on the BRZ, rather than swapping for other Subaru OE wheels.
The Legacy's wheels look almost exactly like Hyundai wheels on the new Genesis Coupe, almost down to the contouring on the spokes. Different PCD, though, obviously.
Regarding the engine: Unless the specs are released, or there are under hood photos, it would be impossible to tell from the outside that the engine would be changed or not.
It would be interesting if Forester's FB25 NA engine replaced the base EJ25 NA engine.
If they were to unfortunately discontinue the slow-selling and order-only Legacy GT... there wouldn't be cam belt to be found on ANY of the 2013 Legacy/Outback, or Tribeca if it survives.
With the Impreza's use of the FB NA engines now... cutting them from Legacy/Outback would pretty much put the naturally-aspirated EJ lineup to bed entirely.
Only the current Forester XT, and WRX/STI motors would be turbo EJs, until the next generation of WRX/STI arrives with the FA/FB based turbo motor debuts, and likely brings the Forester XT along with it, if that survives.
It would be logical for the Legacy/Outback to go FB25 and EZ36 across the line, and a mid-life refresh is as good a time as any.
