After the success of TDI offerings from Volkswagen, Audi’s parent company, Audi takes a step toward fuel efficiency by adding TDI options to the A8, A7, A6 and Q5 in addition to its current A3 and Q7 TDI models.
When Mercedes-Benz began offering a 350 BlueTec diesel model of its S-Class flagship last year, we figured the A8 wouldn’t be long behind with a TDI A8 variant. We weren’t prepared to see Audi add three other TDI models on top of that.
Every Audi TDI model will be fitted with the same turbocharged 3-liter diesel engine.
In the new A8, the TDI engine produces 240 horsepower and 406 pound-feet of torque and makes a 0-60 run in 4.6 seconds. Impressively, the EPA has estimated the fuel economy numbers of the hulking full-size German luxury sedan at 24 MPG in the city and 36 MPG on the highway.
Fuel economy numbers haven’t been specified for the other new TDI offerings but we are sure they’re fairly similar to that of the A8, if not a bit better.
Based upon the increased sticker price from diesel technology and the increased cost of diesel at the pump, we assumed Audi might instead offer hybrid versions before going full sail into TDI.
The A8 TDI will be the first new Audi diesel offering to hit showrooms and will be available in Spring 2013. The A7, A6, and Q5 TDIs, however, won’t enter showrooms until fall 2013.
We will know more next week after Los Angeles International Auto Show and will be able to bring you more specifics at that time.
