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.[citation needed] The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW);[citation needed] 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:[citation needed]
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, boxerconfiguration 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.
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).

updates from AAH to AFC
Valvetrain differences between original AAH design and later AFC design include
1) AFC camshaft provides different valve timing and is lighter. 2) AFC use single valve springs with less mass. 3) AFC inlet and exhaust valves have a smaller stem diameter with revised stem oil seals.
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.

All Volkswagen GroupV8 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 twooverhead 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 longitudinallyfront-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.

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.

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.

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.[6]

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.
This section needs expansion with: valvetrain drive system & valve clearance adjustment, max operating revs. You can help by adding to it. (September 2009)
