flat-4 was retained for the base model. In Europe, the Outback was also available with the 2.0-liter EE20 turbodiesel. The turbocharged EJ25 was dropped from the line. Japanese dealers began selling the new Outback in May 2009. The European debut of the Outback in August 2009 was accompanied by a press release billing the model as a pioneer in the crossover segment. The styling was refreshed for the 2013 model year and base models switched to the 2.5-liter FB25 engine, as announced at the 2012 New York Auto Show. The 2013 model year was also the first time Subaru's advanced driver-assistance system, a stereoscopic camera-based system branded EyeSight, was available in North America. One of the more interesting features introduced from 2016 was tailgate PIN access. Found only on push-button start models, the tailgate features an extra button to the right of the tailgate release button that can be used to enter a PIN, morse-code style, to unlock the car in the lieu of having the fob. The promoted purpose is to allow access to the car where you have deliberately locked the fob inside the car (e.g.: when going to the beach), or if a child or pet has locked themselves inside the car (saves breaking a window). This feature is now available across all Subaru models (including sedans) across all year models that feature push-button start.

The sixth-generation Legacy was previewed as a concept at the Los Angeles Auto Show in November 2013; the Legacy sedan was premiered at Chicago in February 2014, with the Outback following at New York in April. An unrelated Legacy-based "sports tourer" wagon, the Subaru Levorg, was shown in 2013 and first sold in 2014. Elsewhere, the Outback became a free-standing model line of its own, independent of the Legacy, thus bringing greater product differentiation between the two. Subaru billed the exterior styling evolution as being shaped by the concept of 'more Outback', claiming to combine the strengths of passenger cars and sport-utility vehicles and capitalizing on the brand recognition gained from selling the Outback since 1995. EyeSight was offered for the first time in the European market on the new Outback. Chassis stiffness was improved for the fifth-generation Outback. To reduce aerodynamic drag, the side
