The spark-ignition petrol (gasoline) engines listed below were formerly used in various marques of automobiles and commercial vehicles of the German automotive business Volkswagen GroupETKA official factory data and also in Volkswagen Industrial Motor applications, but are now discontinued. All listed engines operate on the four-stroke cycle, and, unless stated otherwise, use a wet sump lubrication system and are water-cooled.

Since the Volkswagen Group is European, official internal combustion engine performance ratings are published using the International System of Units (commonly abbreviated SI), a modern form of the metric system of figures. Motor vehicle engines will have been tested by a testing facility accredited by the Deutsches Institut für Normung (DIN), to either the original 80/1269/ EEC, or the later 1999/99/EC standards. The standard unit of measure for expressing the rated motive power output is the kilowatt (kW); and in their official literature, the power rating may be published in either kilowatts or metric horsepower (abbreviated PS in Wikipedia, from the German Pferdestärke), or both, and may also include conversions to imperial units such as the horsepower (HP) or brake horsepower (BHP). (Conversions: one PS ≈ 735.5 watts (W), ≈ 0.98632 hp (SAE)). In case of conflict, the metric power figure of kilowatts (kW) will be stated as the primary figure of reference. For the turning force generated by the engine, the newton metre (N⋅m) will be the reference figure of torque. Furthermore, in accordance with European automotive traditions, engines shall be listed in the following ascending order of preference: Number of cylinders, engine displacement (in litres), engine configuration, and Rated motive power output (in kilowatts).

The petrol engines which Volkswagen Group is currently manufacturing and installing in today's vehicles can be found in the list of Volkswagen Group petrol engines article.

Air-cooled

The Volkswagen air-cooled engine was introduced in 1935 in Germany, produced in factories all over the world, and the last complete engine was produced in December 2005, Its production was ceased by anti-pollution laws and the last engine was produced in São Bernardo do Campo. Its air-cooled, four-cylinder, boxer configuration was unusual in its day for a production automobile, but has gone on to power millions of vehicles around the world, being considered one of the most reliable automotive engines of all eras.

Water-cooled boxer

The Volkswagen Wasserboxer is a horizontally opposed, or boxer, water-cooled four-cylinder petrol engine. It was introduced in 1982, and was produced for ten years, ending in 1992. The wasserboxer was only used in the Volkswagen Type 2 (T3) (T3 Transporter / Caravelle / Vanagon / Kombi / T25).

Four-cylinder EA111

The EA111 series of internal combustion engines was initially developed by Audi under Ludwig Kraus’s leadership and introduced in the mid-1970s in the Audi 50, and shortly after in the original Volkswagen Polo. It is a series of water-cooled inline three- and inline four-cylinder petrol and diesel engines, in a variety of displacement sizes. This overhead camshaft engine features a crossflow cylinder head design, and directly driven auxiliary units. The exhaust side is in driving direction, closest to the front of the vehicle.
