For those appreciating performance tweaked TDI diesel engines in our VeeDubs, Audi will be enticing us with by putting a the 2.0L TDI in its attractive 2009 TT sports car. The engine is the same diesel that will be in the A4 and the Volkswagen Tiguan, although it will be tuned to crank out 200 horsepower. There isn’t any news that guarantees the U.S. will see this diesel, but it sure would be on my ‘gotta see it list.’ According to LeftLaneNews Audi will debute the TT TDI in March at the Geneva Motor Show.
