What engine does a Subaru Legacy 2006 have?

The 2006 Subaru Legacy was available with two engine options: a 2.5-liter flat-four boxer engine or a 3.0-liter flat-six boxer engine. Both engines were horizontally opposed, a signature design feature of Subaru vehicles.


2.5-Liter Flat-Four Boxer Engine


The standard engine for the 2006 Subaru Legacy was a 2.5-liter flat-four boxer engine. This engine produced 165 horsepower and 166 lb-ft of torque. It was available with either a 5-speed manual transmission or a 4-speed automatic transmission.


3.0-Liter Flat-Six Boxer Engine


An optional engine for the 2006 Subaru Legacy was a 3.0-liter flat-six boxer engine. This engine produced 245 horsepower and 215 lb-ft of torque. It was paired exclusively with a 5-speed automatic transmission.


Both the 2.5-liter and 3.0-liter engines featured Subaru's signature horizontally opposed "boxer" design, where the pistons move side-to-side rather than up-and-down. This layout provides a lower center of gravity, improving the vehicle's handling and stability.


The choice between the two engine options primarily came down to performance and fuel efficiency needs. The 2.5-liter provided a good balance of power and efficiency, while the 3.0-liter offered more robust acceleration and power for drivers seeking a sportier driving experience.
