The sixth-generation Subaru Outback for the North American market was unveiled at the New York Auto Show on April 17, 2019. Full production started from July 29, 2019. This redesigned Outback keeps the same body style (wagon/crossover SUV), while still receiving a few changes, such as new taillights (similar to the ones on the Forester and upcoming Legacy) and an updated, modern interior.

Internally, the 2020 Outback moves to the Subaru Global Platform, which is stiffer and offers a common base to allow use of alternative powertrains, such as hybrid or all-electric. The base model sixth-generation Outback was offered with the 2.5-liter gasoline direct-injection FB25D; a turbocharged 2.4-liter FA24F that was first used on the Subaru Ascent was offered as the uplevel engine, providing improved power, torque, and consumption compared to the discontinued EZ36.

In addition to all-wheel drive coming standard on every trim, the 2021 model year also added LED adaptive steering-responsive headlights (SRH) on premium variants and a seat-belt reminder standard for all passengers.

World markets outside of North America, including Japan, did not launch the sixth generation Outback until 2021.

Australia launched on the 20th February 2021 with a number of differences over the North American version including updated LED headlights with combined Day Running Light and turn/direction indicator with SRH (Steering Responsive Headlights) standard across all variants (the Touring model also gained Adaptive Driving Beam (ADB) until 2023 when ADB became standard across all model variants), as is pushbutton-start with tailgate PIN access. There is improved camera resolution for rear, side and front driver assistance cameras, EyeSight 4.0 with roadside speed sign reading, adjustable speed limiting, and intersection crash avoidance utilising new EyeSight cameras with a wider field of view and a lower profile inside the cabin. Subaru claim the sole engine fitted to Australian Outbacks, the revised 2.5-litre FB25D, is made of 90% new components compared to the Gen5 engine as well. The Japanese Outback was announced on October 7, 2021; in Japan the Outback is offered exclusively with the 1.8-litre CB18 gasoline direct-injection turbo engine instead.

In September 2021, the European variant received a five-star rating by the European New Car Assessment Programme (EuroNCAP) 2021.

For the 2022 model year, Subaru added a new trim level, the Wilderness. Outback Wilderness features 9.5 inches of ground clearance, turbocharged 2.4-liter FA24F engine, and re-tuned transmission gearing with revised front and rear gear ratios. Marketed for off-road use, the Outback Wilderness has 17" wheels with standard all-terrain tires, enhanced body cladding, and synthetic upholstery.
