List of discontinued Volkswagen Group petrol engines

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 Group^[1] 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.^[1]

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.^{[citation needed]} The standard unit of measure for expressing the rated motive power output is the kilowatt (kW);^{[citation needed]} 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:^{[citation needed]}

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^{[by whom?]} one of the most reliable automotive engines of all eras.

Water-cooled boxer

The Volkswagen wasserboxer was 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 / T25).

Eight-cylinder

All Volkswagen Group V8 and W8 petrol engines are constructed from a lightweight, cast aluminium alloy cylinder block (crankcase) and cylinder heads. They all use multi-valve technology, with the valves being operated by two overhead camshafts per cylinder bank (sometimes referred to as quad cam). All functions of engine control are carried out by varying types of Robert Bosch GmbH Motronic electronic engine control units. They are all longitudinally front-mounted, and the V8 engines listed below were for a long time only used in cars bearing the Audi marque, but latterly being installed in Volkswagen Passenger Cars flagship Volkswagen Phaeton.

4.2 V8 40v T 331–353 kW (C5 RS6)

Based on the existing 4.2 V8 from the Audi C5 S6, this engine was tuned with the assistance of VW Group subsidiary Cosworth Technology (now MAHLE Powertrain), and featured two parallel turbochargers, known as biturbo, with two side-mounted intercoolers (SMICs). Enlarged and modified intake and exhaust ports on the new five valve cylinder heads, together with new induction and dual branch exhaust systems, a re-calibrated Motronic engine management system, revised cooling system, and decorative carbon fibre engine covers complete the upgrade.

The initial 331 kW (450 PS; 444 bhp) variant of this engine generates a specific power output of 79.3 kW (107.8 PS; 106.3 bhp) per litre displacement, and the RS6 Plus 353 kW (480 PS; 473 bhp) variant gives 84.6 kW (115.0 PS; 113.5 bhp) per litre.

4.2 V8 FSI 32v

Based on the existing Audi 40 valve V8, this new engine is heavily revised over its predecessor, with all-new components including: crankshaft, connecting rods and pistons, cylinder heads and valvetrain, oil and cooling system, intake and exhaust system, and engine management system. It is available in two versions; a basic or comfort version, first used in the Audi Q7; and a sports-focussed high-revving version, with features borrowed from motorsport, for the B7 RS 4 quattro and the R8. This is the first eight-cylinder road car engine to use Fuel Stratified Injection (FSI), which was successfully developed by Audi in their Le Mans winning R8 racing car. The 5.2 V10 FSI was developed directly from this V8 engine.

5.2 V10 40v FSI (C6 S6/D3 S8)

A first in Audi's history, this new generation high-performance V10 engine is based on Audi's V8 FSI engines, and retains the same fundamental design principals of the V8 FSI, including the crankcase, cylinder heads, valvetrain, fuel system and intake manifold. However, an all new crankshaft, balance shaft, double-chambered intake manifold with dual throttle valves, exhaust manifold, and ECU – are all unique to the V10. As part of the new V10 engine development, specific emphasis was placed on 'refinement', 'comfort' and 'sportiness' – as required for installation in Audi high-performance luxury cars. As well as gaining two additional cylinders compared to the V8, it has been bored by an extra two millimetres, and also shares the 90 degree (°) cylinder bank angle of the recent Audi V engines. Audi continue to use the Fuel Stratified Injection (FSI) technology, originally developed in the Audi R8 LMP endurance race cars.

This engine is often, but incorrectly, referred to as a derivative of the Gallardo's original 5.0-litre Lamborghini V10, which was also developed under the Volkswagen Group ownership. However, the subsequent 5.2 V10 FSI installed in the Gallardo LP560 and Audi R8 V10 is fundamentally identical to this Audi unit, save for a stronger crankshaft with solid main pin design, forged pistons, dry sump oiling system, different intake and exhaust valves, and engine management systems.^[7]
