Of course, Audi's reminder is just another way of advertising its products and, sadly, no actual party is planned to celebrate the TDI engine and the technologies behind it. Suffices to say, since 1989, Audi built some 5 million TDI engines in various displacements and configurations and odds are many more millions are to come.
“20 years of TDI means 20 years of progress and dynamic change, sporty power and efficiency,” Michael Dick, Audi member of the board for technical development said in a release.
“The TDI has been a key factor contributing to the advance of our brand into the premium segment. It has become the world’s most successful efficiency technology that is unsurpassed in the relation of power output to fuel efficiency.”
We will spare you all the phases (available here for all those interested) through which the direct injection, turbocharged diesel engine had to go until it got where it is today. Even if some don't like it, the TDIs are here to stay and, in Audi's garage, their future is spelled "clean diesel."
As you already know by now, Audi will focus its efforts on developing even further the TDI technology, as it is about the single carmaker which put more emphasis on improving existing technologies than creating new, say hybrid, ones.
"The potential inherent in the TDI is far from exhausted. In the past 20 years, Audi has written a tremendous success story with this engine concept – and will continue to do so during the next decade," promises the carmaker.
