23 MPG combined won’t make the 2020 Subaru Ascent a fuel economy champion, but it’s in line with the practical purpose of this large, three-row SUV. Ascent buyers are seeking dependable, all-weather family transport with room for passengers, cargo, and pets. The Subaru badge implies certain priorities, and fuel efficiency sits below capability, safety, and longevity.

City and highway performance

The Ascent’s EPA ratings are 21 MPG in the city and 27 MPG on the highway. These numbers are achieved with Subaru’s 2.4-liter turbocharged four-cylinder engine, which produces 260 horsepower and 277 lb-ft of torque. Paired with a continuously variable transmission (CVT) with eight simulated gears (AV-S8), the Ascent prioritizes smooth, predictable power delivery. The CVT optimizes engine speed for efficiency, but driving style influences whether you achieve the EPA-estimated figures. Aggressive acceleration lowers the city MPG figure. On the highway, maintaining consistent speeds helps realize the advertised 27 MPG. The standard symmetrical all-wheel drive system also plays a role in the MPG. It provides traction in bad weather, and contributes to a minor fuel economy difference compared to front-wheel-drive competitors.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Subaru Ascent at $1,900. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary based on your driving habits, the type of fuel you use (the Ascent runs fine on regular unleaded), and local fuel prices. A driver who commutes in stop-and-go traffic will exceed this annual cost, while someone who mostly takes long highway trips could undershoot it. $1,900 provides a useful baseline when comparing the Ascent’s running costs to other vehicles. You can view ASCENT MPG across all years to compare fuel costs since the model was introduced.

Real-world expectations

The EPA provides baseline data, but real-world MPG often differs. Many Ascent owners report fuel economy figures close to the EPA estimates, but several factors can influence the numbers observed.

Load is a factor. A fully loaded Ascent with passengers and cargo will experience a decrease in fuel economy compared to driving only with the driver. Terrain also plays a role, hilly or mountainous areas require more engine power and result in lower MPG. Weather conditions like strong winds or snow can impact fuel efficiency. All-season tires are standard, but switching to more aggressive off-road tires will likely reduce fuel economy.

How it compares

Within the three-row SUV segment, the 2020 Subaru Ascent’s fuel economy is in the middle. The Honda Pilot achieves up to 23 MPG combined with its front-wheel-drive configuration, while the all-wheel-drive models return around 22 MPG. The Toyota Highlander, particularly the hybrid version, offers better fuel economy, reaching up to 36 MPG combined in the hybrid trims. The non-hybrid Highlander is closer to the Ascent with around 24 MPG combined. The Ford Explorer with the 2.3L EcoBoost engine gets around 24 MPG combined, while the more powerful V6 options are below 20 MPG. The Chevrolet Traverse delivers around 21 MPG combined. For the Ascent buyer, all-wheel drive is a must-have feature, which eliminates the highest mileage trims of some competitors. Drivers considering the Ascent will appreciate the all-wheel drive system and will accept slightly lower MPG figures in exchange for Subaru’s capability.

Tips to maximize efficiency

Smooth and steady saves fuel. The Ascent’s CVT responds well to gentle acceleration and avoiding abrupt changes in speed. Anticipate traffic flow and maintain a consistent pace when possible. Rapid acceleration and hard braking consume more fuel.

Tire pressure is an aspect of fuel efficiency. Ensure that your tires are inflated to the recommended pressure, which can be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Underinflated tires increase rolling resistance and reduce fuel economy.

Minimize unnecessary weight. Carrying extra cargo increases the engine’s workload and reduces fuel economy. Remove items that you don’t need. A lighter vehicle consumes less fuel.

Consider using the Ascent’s “Intelligent” driving mode, if equipped. This mode optimizes throttle response and transmission settings for fuel efficiency. It reduces performance in favor of economy, making it suited to everyday driving.

Regular maintenance is essential for fuel economy. Ensure that your Ascent receives scheduled maintenance, including oil changes, air filter replacements, and spark plug replacements according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently.
