Since the Volkswagen Group is European, officialinternal combustion engine performance ratings are published using theInternational System of Units (commonly abbreviatedSI), a modern form of themetric system of figures.Motor vehicle engines will have been tested by a testing facility accredited by theDeutsches Institut für Normung (DIN), to either the original80/1269/EEC, or the later1999/99/EC standards.[citation needed] The standard unit of measure for expressing the rated motive power output is thekilowatt (kW);[citation needed] and in their official literature, the power rating may be published in either kilowatts ormetric horsepower (abbreviated PS in Wikipedia, from the GermanPferdestärke), or both, and may also include conversions to imperial units such as thehorsepower (HP) orbrake 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, thenewton metre (N⋅m) will be the reference figure of torque. Furthermore, in accordance with European automotive traditions, engines shall be listed in the followingascending order of preference:[citation needed]
TheVolkswagen air-cooled engine was introduced in 1935 in Germany, produced infactories all over the world, and the last complete engine was produced in December 2005, Its production was ceased byanti-pollution laws and the last engine was produced inSão Bernardo do Campo. Itsair-cooled, four-cylinder,boxerconfiguration was unusual in its day for a productionautomobile, 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 VolkswagenWasserboxer is ahorizontally opposed, orboxer, 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 theVolkswagen Type 2 (T3) (T3 Transporter / Caravelle / Vanagon / Kombi / 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.

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 orcomfort version, first used in the Audi Q7; and a sports-focussed high-revving version, with features borrowed from motorsport, for theB7 RS 4 quattro and theR8. This is the first eight-cylinder road car engine to useFuel Stratified Injection (FSI), which was successfully developed by Audi in their Le Mans winningR8 racing car. The5.2 V10 FSI was developed directly from this V8 engine.

A first inAudi's history, this new generation high-performanceV10 engine is based onAudi's V8 FSI engines, and retains the same fundamental design principals of theV8 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 AudiV engines. Audi continue to use theFuel Stratified Injection (FSI) technology, originally developed in theAudi R8 LMP endurance race cars.
This engine is often, but incorrectly, referred to as a derivative of the Gallardo's original 5.0-litreLamborghini V10, which was also developed under the Volkswagen Group ownership. However, the subsequent5.2 V10 FSI installed in the Gallardo LP560 andAudi 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]

fully demand-controlled and returnless; two fuel tank–mounted low-pressure fuel pumps,Fuel Stratified Injection (FSI): two inlet double-cam–driven single-piston high-pressure injection pumps maintaining a pressure between 30 and 100 bar (435 and 1,450 psi) in the two stainless steelcommon fuel distribution rails with an over-pressure release valve set to 136 bar (1,973 psi), ten combustion chamber siteddirect injection solenoid-controlled 65 volt single-hole sequential fuel injectors with integrated swirl plates
ignition system & engine management
mapped direct ignition with centrally mounted spark plugs and ten individual direct-acting single spark coils; twoBoschMotronic MED 9.1 electronicengine control units (ECUs) working on themaster and slave concept due to the high revving nature of the engine, four knock sensors, EU4 emissions standard
exhaust system
vacuum-controlled secondary air injection into exhaust ports to assist cold start operation, 2–1–2 branch exhaust manifold per cylinder bank (650 mm (25.6 in) nominal length) to minimise reverse pulsation of expelled exhaust gases, four close-coupled 600-cell ceramiccatalytic converters, eight heated oxygen (lambda) sensors monitoring pre- and post-catalyst exhaust gases

This was a legacy engine, an original 3.5 litre version was developed nearly 50 years before the takeover ofAutomobili Lamborghini S.p.A. by the GermanVolkswagen Group subsidiaryAUDI 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.
