About 2013 Subaru Legacy The 2013 Subaru Legacy is powered by either a 3.6-liter H6 or a new, more efficient 2.5-liter 4-cylinder powertrain and debuts revised styling for 2013, plus the new EyeSight driver-assist system. The Legacy features new, sportier front styling with new headlights, grille and front bumper. The 2013 Legacy 2.5i models debut a new double-overhead-cam FB series 2.5-liter Boxer engine for increased performance and fuel efficiency. The new engine produces 173 hp and 174 lb.-ft. of torque, compared to 170 hp and 170 lb.-ft. from the previous 2.5-liter engine. More significant is that the new engine produces greater low-end torque across a broad speed range, making the 2013 Legacy 2.5i models more responsive in everyday driving. Legacy 2.5i offers a choice between a standard 6-speed manual transmission and the second-generation Lineartronic CVT. The 2013 Legacy 3.6R continues with a 256-horsepower 3.6-liter 6-cylinder Boxer engine and 5-speed electronically controlled automatic transmission. A downshift "blipping" feature adds a sporty feel when using the Legacy 3.6R steering wheel paddle shifters. The 2013 Legacy debuts Subaru's new EyeSight driver-assist system, which integrates Adaptive Cruise Control, Pre-Collision Braking and Vehicle Lane Departure Warning. EyeSight uses a stereo camera design developed by Subaru to provide a detection angle wider than that of radar-based systems. Numerous enhancements to the body structure, suspension and steering give the Legacy a smoother and quieter ride for 2013, while also delivering improved handling agility.
