List of discontinued Volkswagen Group petrol engines
All listed engines operate on the four-stroke cycle, and, unless stated otherwise, use a wet sump lubrication system and are water-cooled.
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?]
This overhead camshaft engine features a crossflow cylinder head design, and directly driven auxiliary units.
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.
The 2.8 V6 is a stroke-reduced version of the 3.2 V6 FSI introducing the Audi valvelift variable control of inlet valve lift.
They all use multi-valve technology, with the valves being operated by two overhead camshafts per cylinder bank (sometimes referred to as quad cam).
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).
It is constructed in two distinct stages: all components within the cylinder block and crankcase are built up at the Audi Hungaria Motor Kft.
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.
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.
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] 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 final model to use this was the Murciélago, which was released during the current VW Group ownership, developed with help from Audi.
