The 2021 Subaru Ascent Limited or Touring with the 2.4L turbocharged engine gets an estimated 22 MPG combined. This isn’t going to win any efficiency awards, but it’s what you can expect to get from a capable three-row SUV with standard all-wheel drive. The Ascent is a practical, family-oriented vehicle designed for weekend adventures and the demands of daily life, not for breaking fuel economy records.

City and highway performance

The Ascent’s 20 MPG city and 26 MPG highway ratings show its strengths and weaknesses. Urban driving, with its constant stop-and-go, puts a strain on larger vehicles. The turbocharged engine needs to work to get the Ascent moving from a standstill. However, the highway figure is more respectable. Once up to speed, the Ascent settles into a comfortable cruise, and the engine doesn’t need to work as hard to maintain momentum. This makes it a decent choice for longer road trips, where the spacious interior and comfortable ride are appreciated.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Subaru Ascent Limited/Touring at $2,000. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price when the EPA performed its tests. Individual fuel costs will vary depending on local gas prices and driving habits. Drivers who drive mostly in the city will likely exceed this estimate, while those who spend most of their time on the highway might come in slightly under.

Real-world expectations

The EPA estimates provide a useful baseline, but real-world fuel economy will vary. Factors like driving style, tire pressure, cargo weight, and even weather conditions can all impact your MPG. Aggressive acceleration and hard braking will quickly diminish fuel economy. Maintaining proper tire inflation and minimizing unnecessary weight in the vehicle will help. Avoiding roof racks when possible is smart. They disrupt the Ascent’s aerodynamics and force the engine to work harder. Owners often report numbers close to the rated figures, but it’s important to drive with fuel efficiency in mind if you want to achieve the EPA’s estimates.

How it compares

The Ascent’s fuel economy is reasonable for its class. It’s important to consider the competition. The Toyota Highlander, for example, achieves 24 MPG combined with its standard V6 engine in front-wheel drive form. The Kia Telluride, a popular alternative, also comes in at 22 MPG combined. The Ford Explorer, depending on the engine and drivetrain, can range from 21 to 27 MPG, with the hybrid version achieving even better economy. The Ascent has a standard AWD system, while others offer AWD as a costly add-on that can negatively affect expected MPG totals. For shoppers prioritizing all-weather capability without wanting to lose too much fuel economy, the Ascent presents a suitable compromise. See ASCENT MPG across all years to check historical trends.

Tips to maximize efficiency

The Ascent’s Intelligent (I) mode, accessible via the SI-DRIVE button, prioritizes fuel efficiency by dulling throttle response and optimizing the transmission’s shift points for lower RPMs. Use this mode during everyday driving, especially in congested traffic. It won’t transform the Ascent into a hybrid, but it can noticeably improve your MPG.

The Ascent’s 2.4L turbo engine benefits from smooth acceleration. Avoid aggressive launches and try to maintain a steady pace. The engine is more efficient when it’s not being pushed hard. A gentle touch on the accelerator will not only save fuel, but also provide a more comfortable ride for your passengers.

Pay attention to your tire pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended PSI listed on the driver’s side door jamb. This simple step can make a meaningful difference in your fuel economy over time.

Weight reduces fuel efficiency. The Ascent is designed to haul people and cargo, but unnecessary weight in the vehicle makes the engine work harder. Remove any items from the vehicle that you don’t need, especially heavy objects. This includes things like sports equipment, tools, and even extra gear that you might be storing in the cargo area.

Consider the maintenance schedule specified by Subaru. Items such as spark plugs, air filters, and motor oil all affect the overall efficiency of the Ascent. Old spark plugs can reduce the efficiency of combustion, while a dirty air filter can restrict airflow to the engine. Follow the recommended service intervals to keep your Ascent running at its best.
