How far can a Subaru Ascent go on a full tank of gas?
On a full tank, the Ascent typically covers about 440 miles in mixed driving and more than 520 miles on highway trips, depending on model year and conditions.
This article explains how to estimate range using the vehicle’s fuel-tank capacity and EPA-friendly efficiency figures, and discusses factors that can change the actual distance you can travel between fill-ups.
Fuel capacity and EPA estimates
Tank size and efficiency
The latest Subaru Ascent models with the 2.4-liter turbo engine and all-wheel drive use a 19.3-gallon fuel tank. EPA ratings for this setup are typically about 21 mpg in the city, 27 mpg on the highway, and 23 mpg combined, which yields baseline range estimates as follows:
- City range: roughly 405 miles (19.3 gallons × 21 mpg)
- Combined range: roughly 444 miles (19.3 gallons × 23 mpg)
- Highway range: roughly 521 miles (19.3 gallons × 27 mpg)
These figures serve as a baseline; real-world range varies with driving conditions and the specific model year.
Factors that affect range
Before listing the main variables, note that actual distance on a full tank depends on multiple factors that can swing results above or below these estimates.
- Driving style and throttle application
- Use of all-wheel drive and vehicle load (passengers and cargo)
- Weather, terrain and altitude
- Tire type, pressure, and road surface
- Maintenance, fuel quality, and fuel-calibration differences by model year
In practice, expect real-world ranges to vary. Monitoring the vehicle's on-board range indicator helps you plan refueling more accurately.
Summary
In short, a Subaru Ascent with a 19.3-gallon tank and the 2.4-liter turbo engine achieves about 21 mpg city, 27 mpg highway, and 23 mpg combined according to EPA estimates. That translates to roughly 405 miles in city driving, about 444 miles on a mixed cycle, and around 521 miles on highway driving. Real-world results can differ based on conditions, equipment, and maintenance. For the latest model-year specifics, consult Subaru's official specifications or the EPA database.
