Audi has revealed its biggest SUV yet with the launch of the new Q9. The luxury seven-seat flagship is designed to rival luxury family SUVs such as the BMW X7 and Mercedes-Benz GLS and will go on sale in dealers in September. Inside, the Q9 features a three-screen dashboard comprising a 14.5-inch infotainment display, 11.9-inch digital driver’s display and a 12.3-inch passenger screen. Luxury features include electrically adjustable seats throughout the cabin, with the front seats gaining heating, ventilation and massage functions as standard. Audi has confirmed the Q9 will go on sale next month, with the first UK customer deliveries expected before the end of the year.
