Unlocking the Savings: How Many Miles Can You Get on a Subaru Legacy?

As car enthusiasts, one of the first things that come to mind when buying a car is how fuel-efficient it is. With rising fuel costs and the need to be environmentally conscious, consumers are looking for cars that offer excellent gas mileage. One such car is the Subaru Legacy. In this guide, we will explore how far you can go on a Subaru Legacy and what affects its fuel efficiency.

Subaru Legacy and Fuel Efficiency

The Subaru Legacy is a midsize sedan that has been on the market since 1989. It is known for its reliability, safety features and all-wheel drive capability. Its fuel efficiency has always been a selling point for the vehicle. The Subaru Legacy is rated at an average of 23 miles per gallon (mpg) in the city and 30 mpg on the highway. These ratings are for the base model with a 2.5 liter, four-cylinder engine, and continuously variable transmission (CVT).

Trim Levels and MPG Variations

The Subaru Legacy comes in six different trim levels — the Base, Premium, Sport, Limited, Limited XT, and Touring XT. The higher trim levels have more features, but they also have a bigger engine, which affects fuel economy. The Premium, Sport, and Limited all have the same fuel efficiency as the base model. The Limited XT, and the Touring XT, however, have a 2.4 liter, four-cylinder turbocharged engine that delivers 260 horsepower and 277 lb-ft of torque. These higher-end models have a lower mpg rating of 22 mpg in the city and 29 mpg on the highway.

Driving Habits and Fuel Efficiency

Several factors can affect a car’s fuel economy, and the Subaru Legacy is no exception. One such factor is driving habits. Aggressive driving or excessive idling can lower fuel efficiency.
