20 years of TDI engines
AUDI AG celebrated the 20th anniversary of the development of the TDI engine in 2009. The
first Audi model with a direct-injection turbodiesel engine, the Audi 100 2.5 TDI, was unveiled at
the Frankfurt Motor Show (IAA) in fall 1989. The abbreviation TDI was used to denote a combi-
nation of direct injection, turbocharging and fully electronic engine management that heralded
in a new dimension of drive technology. The TDI has radically altered the image of the noisy
diesel engine and played a decisive part in the Audi brand’s development and ascent into the
premium segment. Today, this efficient technology that combines powerful propulsion with
thrifty fuel economy can be found in the product range of virtually every car manufacturer.
