Chronology
PredecessorVolkswagen air-cooled engine

The Volkswagen wasserboxer is a four cylinder horizontally opposed pushrod overhead-valve (OHV) petrol engine developed by Volkswagen. The engine is water-cooled, and takes its name from the German: "Wasserboxer" ("water-boxer"); with "boxer" being another term for horizontally opposed engines. It was available in two displacements – either a 1.9-litre[1] or a 2.1-litre;[1] the 2.1-litre being a longer-stroke version of the 1.9-litre, both variants sharing the same cylinder bore.[1] This engine was unique to the Volkswagen Type 2 (T3) (Transporter T3 / Caravelle / Vanagon / T25), having never been used in any other vehicle.[1] Volkswagen contracted Oettinger to develop a six-cylinder version of this engine. Volkswagen decided not to use it, but Oettinger sold a Volkswagen Type 2 (T3) equipped with this engine.[2]
