Audi's redesign of its luxury three-row SUV has resulted in a lighter-weight SUV that sits lower than the previous generation. It employs Audi's supercharged 3.0-liter V6, which puts out 333 hp and is mated to a supersmooth eight-speed automatic. The result is effortless acceleration, and fuel economy of 20 mpg overall in our tests. The new Q7 is very quiet, instilling a sense of calm and tranquility. Ride comfort is commendable, and if you splurge for the Prestige trim with the optional air suspension, it has the plushness and control of a luxury car. Handling is responsive and confidence-inspiring for such a large vehicle. The beautifully finished interior exudes luxury, with excellent seats and a vivid, high-tech digital instrument cluster. But it is a steep learning curve to master the controls.
