Audi AG is a German automobile manufacturer that designs, engineers, produces, markets and distributes luxury automobiles. Audioversees worldwide operations from its headquarters in Ingolstadt, Bavaria, Germany. Audi-branded vehicles are produced in nine production facilities worldwide.
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
Reliable, Economical, Powerful
120-240 PS/ 2.0L / 250-500 N·m / stock performance
The 2.0 TDI is a very widely used Audi engine, present in most Audi models. The engine benefits from high fuel economy and above average performance. This motor was even present on the MK2 Audi TT.
Early models of the 2.0TDI have some issues, so it's better to stay away from pre-2007 year examples.
Some models are fitted with a diesel particulate filter. According to Audi (UK) 'TDV' stands for Technology Development Vehicle. TDV denotes that a diesel particulate filter is present on the Audi in question but the vehicle was produced just prior to (or during) the legislation process regarding DPF's. The abbreviation 'DPF' was not yet officially in existence so Audi used the 'TDV' letters to identify the diesel particulate filter. This Pumpe Düse (PD) TDI engine was introduced to replace the older higher-powered versions of the 1.9 TDI. It is the first four-cylinder 16-valve double overhead camshaft (DOHC) Turbocharged Direct Injection (TDI) engine made by Volkswagen Group.
