26 MPG combined isn’t going to win any efficiency awards, but it represents a sensible compromise in the 2024 Subaru Legacy 2.4L turbo. This isn’t a hyper-efficient hybrid. It’s a mid-size sedan with standard all-wheel drive and a punchy turbocharged engine. The Legacy 2.4T appeals to buyers who want confident all-weather performance and strong acceleration over ultimate fuel savings. They live in places where snow falls, and they want the security of AWD without sacrificing too much driving enjoyment.

City and highway performance

The EPA estimates the 2024 Legacy 2.4L will achieve 23 MPG in the city and 31 MPG on the highway. The city number reflects the penalty for hauling around an AWD system in stop-and-go traffic. The Legacy’s automatic start/stop system helps to mitigate some fuel consumption during red light waits. The 31 MPG highway figure is more respectable and achievable during steady cruising. Subaru’s Lineartronic CVT (Continuously Variable Transmission), programmed with eight simulated gears (AV-S8), helps keep the engine in its optimal rev range for fuel efficiency when you’re not demanding maximum power.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2024 Subaru Legacy 2.4L turbo at $1,700. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes the use of regular unleaded gasoline and factors in the national average fuel price. This $1,700 figure provides a useful baseline for comparison, but your actual fuel costs will vary depending on your driving habits, local fuel prices, and the specific conditions in which you typically drive. If you live in a region with higher gas taxes or do a lot of aggressive driving, expect to pay more.

Real-world expectations

EPA estimates provide a standardized benchmark, however, real-world fuel economy depends heavily on individual driving styles and conditions. If you have a lead foot or mostly drive in the city, expect numbers slightly below the EPA estimates. Conversely, you might exceed the highway figure on long road trips at a consistent speed. Factors such as tire pressure, vehicle load, and even the use of accessories like air conditioning can influence fuel consumption. You can monitor your Legacy’s trip computer and adjust your driving habits to help achieve the best possible mileage.

How it compares

The Legacy 2.4T lands somewhere in the middle compared to other mid-size sedans with optional AWD. The Toyota Camry AWD, for example, achieves a combined 29 MPG with its naturally aspirated 2.5L engine, making it a slightly more fuel-efficient choice. The Nissan Altima AWD also boasts 29 MPG combined with its 2.5L engine. However, neither of those alternatives offers the turbocharged punch of the Legacy’s 2.4-liter engine or its standard AWD on all trim levels. Those prioritizing fuel economy above all else might consider cars like the Hyundai Sonata Hybrid, which can easily surpass 50 MPG combined in real-world driving. The Legacy 2.4T offers a reasonable compromise for those who want AWD without completely sacrificing performance.

Tips to maximize efficiency

Take advantage of the Legacy’s SI-Drive system, and select “Intelligent” mode for daily commutes and around-town driving to prioritize fuel efficiency. This mode adjusts the throttle response to be less aggressive, encouraging smoother acceleration and conserving fuel.

Regularly check and maintain your tire pressure. Underinflated tires increase rolling resistance, which directly impacts fuel economy. The recommended tire pressure for your Legacy is listed on a sticker inside the driver’s side door jamb.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. The Legacy’s automatic start/stop system handles this for you in many situations, but you can manually shut it off if needed. Conserving fuel helps.

Plan your trips strategically. Combine errands into a single outing to minimize cold starts because cold starts are particularly fuel-intensive. Reducing the number of times you start the engine each day can make a noticeable difference.

Keep up with scheduled maintenance, especially air filter replacements. A clogged air filter restricts airflow to the engine, reducing performance and fuel efficiency. Stick to the maintenance schedule outlined in your owner’s manual to keep your Legacy running at its best. Be sure to see all Subaru fuel economy data as well.
