Audi is making a big diesel push, introducing three more TDI models.

Audi is expanding its TDI models with the A6 TDI, A7 TDI and Q5 TDI.

These new TDI clean diesel models join the newly-introduced A8 L TDI, and highly-successful Q7 TDI.

EPA estimated fuel economy figures for the new clean diesel introductions are as follow:

  • 2014 Audi A6 TDI – 24 city/ 38 highway/ 29 combined MPG
  • 2014 Audi A7 TDI – 24 city/ 38 highway/ 29 combined MPG
  • 2014 Audi Q5 TDI – 24 city/ 31 highway/ 27 combined MPG

The all-new Audi A3 sedan, arriving in 2014, will also be available with a TDI clean diesel engine.

“Audi has been at the forefront of clean diesel since the introduction of Audi TDI technology in the U.S. in 2009,” said Scott Keogh, President, Audi of America. “As drivers increasingly look for high fuel efficiency and low-emissions output, demand for diesel is on the rise. The introduction of the highly-efficient Audi A6, A7 and Q5 TDIs continue Audi’s commitment to clean diesel technology and further the brand’s focus on balanced performance solutions that improve efficiency and driving dynamics.”

Starting at $57,500, the 2014 A6 TDI available this coming summer is equipped with a 6-cylinder clean diesel engine, an 8-speed Tiptronic transmission and quattro all-wheel drive. The A6 TDI’s engine will produce 240 horsepower and 428pound-feet of torque.

The A6 TDI will reach 60 mph in 5.5 seconds.

The 2014 Audi A7 TDI starts at $66,900 and will also go on sale in the summer of 2013 and will be equipped with the same powertrain and performance as the A6 TDI.

Starting at $46,500, the Q5 TDI is powered by the sameV6 engine and eight-speed Tiptronic transmission that generates 240 horsepower and 428 pound-feet of torque.

The Q5 TDI accelerates from 0-60 MPH in 6.5 seconds.

Q5 models with a four-cylinder 2.0T engine, six-cylinder 3.0T engine, and hybrid engine will also be available in 2014.
