2015 Subaru Outback

The 2015 Subaru Outback is a popular wagon/SUV known for its reliability, standard all-wheel drive, and spacious interior. Engine options included a 2.5L naturally aspirated four-cylinder and a 3.6L six-cylinder. The 2.5L produced 175 horsepower and 174 lb-ft of torque. Both engines were paired with a Lineartronic CVT (Continuously Variable Transmission). Owners generally appreciate the Outback’s fuel efficiency (especially with the 2.5L), comfortable ride, and cargo capacity. Common complaints revolve around the CVT’s performance (some find it sluggish), the infotainment system’s responsiveness, and the overall driving experience not being particularly sporty.
