2.5l R5 TFSI engine
Introduction
Audi was the brand most noted for its five-cylinder engines in the
1980s. The powerful engines sharpened the new, sporty profile
and reinforced Audi's proverbial "Vorsprung durch Technik".
The five-cylinder engines combined the efficiency of a four-cylin-
der with the cultivation of a six-cylinder at a lower weight and in a
compact size. A turbocharged version was later launched. It was
the first engine concept to embrace the principle of downsizing*
and it caused a sensation when it was first unveiled 30 years ago.
