List of discontinued Volkswagen Group petrol engines

The spark-ignition petrol (gasoline) engines listed below were formerly used by various marques of automobiles and commercial vehicles of the German automotive concern, 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 Deutsches Institut für Normung (DIN) accredited testing facility, to either the original 80/1269/ EEC, or the later 1999/99/EC standards. The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW); and in their official literature, the power rating may be published in either kW 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 (Nm) 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:

  1. Number of cylinders,
  2. engine displacement (in litres),
  3. engine configuration, and
  4. 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 petrols

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' petrols

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).

Four cylinder EA111 petrols

The EA111 series of internal combustion engines was initially developed by Audi under Ludwig Kraus 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.

2.7 V6 30v T 280kW (B5 RS4)

Based on the Audi B5 S4 2.7 V6 biturbo, this engine was tuned by Cosworth Technology (now MAHLE Powertrain), and featured enlarged intake and exhaust ports on the cylinder heads, two uprated parallel turbochargers, and two side-mounted intercoolers (SMICs), together with new induction and exhaust systems, and a re-calibrated engine management system. Due to the high performance nature of the vehicle, it was also fitted with a multi-baffled two-section oil sump to help prevent oil starvation during high g-force manoeuvres.

As of February 2010, this engine generates the highest specific power output of all (even current) Volkswagen Group engines. With its 280 kW (381 PS; 375 bhp) output, that gives this engine a specific power output of 104.8 kW (142.5 PS; 140.5 bhp) per litre displacement.

The AFC engine had a revised lubrication circuit and oil pan assembly, constructional detail includes
1) AFCs use a larger oil filter. 2) AFC engine oil cooler has a larger cross-sectional area. 3) AFC engines oil pressure relief valve is integrated into a cover assembly. 4) AFC engines oil pickup is integrated into the upper section of the oil sump, with a revised lower oil sump gasket.

Eight cylinder petrols

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 331-353kW (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.

Ten cylinder petrols

5.0 V10 40v (Lamborghini)

Only the third engine developed by Automobili Lamborghini S.p.A., and the first since Lamborghini was acquired by AUDI AG, this engine shares many technologies with other Audi-developed engines, although it is not directly based on any existing designs. It is constructed in two distinct stages: all components within the cylinder block and crankcase are built up at the Audi Hungaria Motor Kft. factory in Győr, with final assembly being completed at Sant'Agata Bolognese.

Twelve cylinder petrols

6.2/6.5 V12 48v (Lamborghini)

This was a legacy engine, an original 3.5 litre version was developed nearly 50 years before the takeover of Automobili Lamborghini S.p.A. by the German Volkswagen Group subsidiary AUDI AG. The current 6.2 and 6.5 litre versions can trace their lineage to the original. The final model to use this was the Murciélago, which was released during the current VW Group ownership, developed with help from Audi.
