Audi's luxury SUV is roomy and nicely finished inside. The standard powertrain is a supercharged V6 paired with an eight-speed automatic. A more frugal 3.0-liter V6 turbodiesel version is also offered. It is relatively refined and delivers a long cruising range. Handling is fairly nimble, but the Q7 doesn't shine at its limits. The ride is steady, though it's rather stiff at low speeds. Front-seat comfort is excellent, interior fit and finish is impressive, and the cabin is quiet, but the MMI driver-interaction system and associated controls are complex. A very snug third-row seat is standard.
