Audi has a habit of using round numbers to signal ambition, and assigning the Q9 badge to its new flagship SUV is no accident. Size and StanceThe Q9 measures 5.31 metres long, 2.21 metres wide, and 1.81 metres tall, with a 3.14-metre wheelbase. Two exterior lines are offered: the standard advanced trim and the optional S line, which takes a sportier approach. Interior and SeatingSeven seats are standard, with an optional six-seat layout that replaces the second-row bench with two individual electrically adjustable chairs. The panoramic sunroof is the largest ever fitted to an Audi, covering more than 1.5 square metres of glass.
