Are luxury SUVs not your thing? For Audi, there is only the Audi A8. Serving as the flagship model of the range, the A8 is Audi's contender against the likes of the Mercedes-Benz S-Class, Lexus LS, and the BMW 7 Series. From its four-zone automatic climate control, to the huge touchscreen inftotainment system, as well as the rear entertainment system, the A8 comes with plenty of toys. Propelling all of this is 3.0-liter twin-turbo V6 that is connected to an eight-speed automatic transmission with Quattro all-wheel drive.
