Tow package contents
The 2021 Subaru Outback does not offer a specific "tow package" from the factory. However, a Class I trailer hitch receiver is available as a port-installed or dealer-installed accessory. The Outback comes standard with Trailer Stability Assist, which uses the vehicle's stability control system to help quell trailer sway. Aftermarket trailer brake controllers can be installed.
Weight distribution & WDH requirements
Subaru does not recommend the use of a weight-distribution hitch with the Outback.
Real-world towing tips for this vehicle
- When towing with your Outback, be mindful of the tongue weight. The maximum tongue weight for both the 2,700-lb and 3,500-lb towing capacities is 10% of the trailer weight.
- Due to the Outback's unibody construction and continuously variable transmission (CVT), it is important to avoid abrupt starts and stops. Smooth acceleration and braking will help to reduce strain on the drivetrain.
- When towing on long grades, you may find it helpful to use the manual shift mode to keep the engine in its powerband.
Common towing-related issues
The most common towing-related issue with the 2021 Subaru Outback is exceeding the vehicle's tongue weight capacity. This can cause the rear of the vehicle to sag, which can negatively affect handling and braking. It is also important to note that the Outback's CVT may be more susceptible to wear and tear when towing heavy loads on a regular basis.
