Top 5 Greatest Audi Engines

3. 2.5-Liter Turbo I5

The 2.5-liter five-cylinder turbo is a distant ancestor of Audi’s legendary five-cylinder engines from the 1980s. It’s a thoroughly modern powerplant, capable of producing over 400 horsepower, transforming cars like the Audi TT and Audi A3 into feral beasts.

I’m convinced Audi’s soul is in the turbo five-cylinder engine. The 2.5-liter version shares only two things with its ancestor – the number of cylinders and the bear-like growl. The noise is the unmistakable sound of mischief, whether on a rally stage, at the track, or against an unsuspecting BMW 2 Series.
