Audi A3 TDI delivers stellar fuel economy, so-so cabin tech
CNET Car Tech reviews the 2010 Audi A3 TDI.
Audi follows in parent company Volkswagen's footsteps by bringing a car to the U.S. with a TDI diesel engine. Using the same turbocharged 2-liter diesel engine as the VW Jetta, the A3 TDI offers the same stellar fuel economy as its lesser German cousin, and it has better cabin tech, including a good iPod connection and Bluetooth phone system. However, Audi lets the A3 TDI simmer with an older version of its navigation system that's not quite on par with its latest technology.
