Audi has produced some sweet, durable and also very powerful engines along the years. In the last 10 years Audi has always had an engine in the "top ten engines of the year". So keep calm and love Audi !

Audi engines can withstand some decent amounts of hp and torque after tuning, so spending money on your car is a real good investment !

Here is our top Audi Engines list


V8 4.2 40v


Monster INC. Placed in the 2005 and 2006 annual list of Ward's 10 Best Engines

334-553 PS/ 4.0-4.2L / 420-700 N·m / stock performance

Of their eight-cylinder petrol engines, all Volkswagen Group V8 engines are primarily 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.

These V8 petrol engines initially were only used in cars bearing the Audi marque, but are now also installed in Volkswagen Passenger Cars 'premium models'. They are all longitudinally orientated, and with the exception of the Audi R8, are front-mounted.

We will be skipping the 4.2 V8 32v FSI which was originally placed on the Audi R8
