Technology geeks who sank every penny into Google’s IPO can add plenty of fun features to the 2007 Audi Q7. You can equip the SUV with a rearview camera for backing assistance, a navigation system with voice control, and a keyless locking and ignition system. Headlights that automatically swivel to illuminate corners are offered, as well as a lane-change warning system called Side Assist that monitors the Q7’s blind spots. Adaptive cruise control that operates between 0 and 90 mph and automatically adjusts speed based on traffic conditions is available, and the adaptive air suspension adjusts ride height for both off-roading and loading while managing cornering forces on twisty roads.
