 The Q7 TDI with the 8 speed automatic is a pleasure to drive. This is not your typical diesel found in US cars. The TDI is very quiet but really strong, the torque provides a very smooth acceleration and the 8 speed transmission shifts flawlessly.On a recent highway trip to Atlanta, Ga we locked the cruise in at 78 and were getting 26.6 MPG with 3 adults. The Audi MMI ( multi media interface that controls the nav, music and voice recognition works great. I really like the Goggle Earth Navigation.The MMI allows for up to 8 devices to be connected through WiFi.The seats are comfortable and 2 position seat memory works well for the needs of 2 different sized drivers.
