Does 2015 Subaru Legacy have turbo?

The 2015 Subaru Legacy does not come with a turbocharged engine. It relies on naturally aspirated powertrains: a 2.5-liter flat-four in most trims and a 3.6-liter flat-six on the top-tier models.

For context, this article reviews the official engine options for the 2015 Legacy and how turbocharged power fits into Subaru's broader Legacy history.

Engine options in the 2015 Legacy

Below is a concise look at the two engines available for the 2015 Legacy and how they are typically paired with transmissions.

• 2.5-liter horizontally opposed four-cylinder engine (flat-4), naturally aspirated. It is paired with a continuously variable transmission (CVT) in most trims and delivers roughly 170–175 horsepower.


• 3.6-liter flat-six engine, naturally aspirated. It produces about 256 horsepower and is available on higher trims, typically paired with an automatic transmission.

In short, the 2015 Legacy lineup offers two non-turbo engines across its range, with the larger displacement engine reserved for premium trims.

Turbocharged history in the Legacy line

Subaru has offered turbocharged Variants in earlier Legacy generations, but not in the 2015 model year. Past turbo models included turbocharged versions of the early 2.5-liter and, in some markets, other smaller turbo engines. The 2015 edition, however, sticks with naturally aspirated powertrains only.

Conclusion: For buyers seeking turbo performance in a Legacy, they would need to look at older generations or alternative Subaru models, as the 2015 Legacy does not include a factory turbo option for the U.S. market.

Summary

The 2015 Subaru Legacy does not offer a turbocharged engine. It is powered by two naturally aspirated options—the 2.5-liter flat-4 and, on higher trims, the 3.6-liter flat-6—with no factory turbo available for that model year in the United States.

Does the 2015 Subaru Legacy have a turbo?

As recently as 2012, Subaru offered a 2.5 liter four cylinder turbo in a GT version, but this car will not be available with a turbo. Twin pod or "binocular" instrument cluster continues a theme that Subaru began on the Tribeca.
