50 years of the Boxer
SUBARU 50th ANNIVERSARY OF THE BOXER ENGINE
Subaru is celebrating the 50th anniversary this year, of its horizontally-opposed ‘Boxer’ engine (so called due to the engine’s pistons resembling the punch-counterpunch motion of a boxer’s fists). With the horizontally-opposed design of Subaru’s Boxer engine, the opposing pistons work to cancel out the inertia force of each other, resulting in less vibration and superb rotational balance to provide smooth acceleration right up to the highest engine speeds. Its compact form also allows it to be fitted lower in the engine bay than a conventional four-in-line engine, lowering the centre of gravity.
Subaru’s signature Boxer engine was first introduced on the Subaru 1000 compact passenger car in 1966. Every vehicle sold today by Subaru is fitted with a Boxer engine and Symmetrical All-Wheel Drive (AWD) system. Subaru Symmetrical (AWD) offers a combination of superior stability and traction, with the symmetrical layout of the drivetrain allowing a balanced weight distribution, aided by the longitudinally-mounted Boxer engine.
