The 2023 Subaru Ascent’s 2.4L turbocharged four-cylinder gets 22 MPG combined, which isn’t going to win any efficiency awards. However, it’s an acceptable compromise for buyers who prioritize space, safety, and all-weather capability. The Ascent competes in a crowded three-row SUV segment, and its fuel economy isn’t class-leading. It’s a known quantity for active families who need the extra seats and cargo capacity and demand standard all-wheel drive.

City and highway performance

The EPA estimates the 2023 Subaru Ascent will achieve 20 MPG in the city and 26 MPG on the highway. These numbers reflect the inherent trade-offs of a large SUV. City driving, with its constant stop-and-go, works the Ascent’s engine and eight-speed automatic transmission (AV-S8) harder, impacting fuel consumption. The highway figure, while better, is still influenced by the vehicle’s size, weight, and the drag created by its blocky shape. Subaru’s symmetrical all-wheel drive system, standard on every Ascent, also contributes to slightly lower MPG compared to front-wheel-drive competitors.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Subaru Ascent at exactly $2,000. This figure is based on driving 15,000 miles per year, using a blend of 55% city and 45% highway driving, and factoring in national average fuel prices. It’s a useful benchmark for comparison, but individual experiences will vary based on driving habits and local fuel costs. Fluctuating gas prices can significantly impact this annual figure; the higher gas prices climb, the more that $2,000 estimate will increase.

Real-world expectations

The EPA provides a standardized benchmark, but real-world MPG often deviates. Hauling kids to soccer practice, weekend camping trips with a loaded cargo area, or simply battling rush-hour traffic can all negatively affect fuel economy. Ascent owners frequently report figures in line with the EPA estimates, but achieving the rated 26 MPG on the highway requires a conscious effort to maintain consistent speeds and avoid aggressive acceleration. The turbocharged engine rewards a light foot. It also tempts drivers with its readily available power, which can diminish fuel savings. Consider checking the ASCENT MPG across all years to learn how the figures might vary for different model years.

How it compares

The Ascent’s fuel economy places it mid-pack within its competitive set. The Toyota Highlander, for instance, achieves an EPA-estimated 25 MPG combined with its standard V6, while the hybrid version gets a remarkable 36 MPG combined. The Honda Pilot, a key rival, comes in at 22 MPG combined in its front-wheel drive configuration, though opting for all-wheel drive drops that figure slightly. The Ford Explorer, depending on the engine, can range from 21 to 24 MPG combined. For buyers considering these vehicles, the Ascent presents a familiar combination of all-wheel drive capability and practical interior space, and it represents a viable option even if its fuel economy isn’t the absolute best in class. Comparing all Subaru fuel economy data can highlight the brand’s overall efficiency relative to its rivals.

Tips to maximize efficiency

Gentle acceleration is important to saving fuel. The Ascent’s turbocharger delivers ample torque, but avoid stomping on the gas pedal unless truly necessary. Smooth, gradual acceleration will help keep the engine operating in its most efficient range and prevent unnecessary fuel consumption.

Regular maintenance pays dividends over the long term. Keep the tires properly inflated to the recommended pressure, as this reduces rolling resistance, which improves MPG. Schedule routine servicing, including oil changes and air filter replacements, to ensure the engine is running optimally.

Reduce excess weight whenever possible. Removing unnecessary items from the cargo area can lighten the load and improve fuel efficiency. Every extra pound adds up, so decluttering the vehicle can make a small but noticeable difference, especially on longer trips.

Plan routes strategically to avoid congestion. Stop-and-go traffic wastes fuel. If possible, use navigation apps to identify and avoid heavily congested areas, opting for routes that maintain a more consistent speed. Combine errands into a single trip to reduce cold starts, which consume more fuel.
