The Alfa Romeo Boxer engine was a water-cooled flat-4 piston engine, developed by Alfa Romeo for front-wheel drive, and longitudinal applications. It debuted on the Alfasud, which was introduced in 1971 at the Turin Motor Show.[1] In the following decades the Boxer went through several upgrades and powered many Alfa Romeo front-wheel drive cars up to 1996 (not the 164). In 1997 it was phased out and replaced by the transversely-mounted Twin Spark engines.
