In terms of performance, the Audi A5 is very efficient because it's powered by a Quttro all-wheel drive train. Inside the cabin, the interior has impressive high-end elements that can rival most upscale sedans. The standout cabin technologies include a 7.0-inch infotainment system, an MMI interface, and an 8.3-inch navigational display. There are a wide range of safety features; the highlights include automatic emergency braking, a lane-keeping assist system, and adaptive cruise control. Optional packages are available for the Audi A5 Sportback. The Audi Guard Protection Kit adds all-weather mats, and the Cold Weather Package equips the A5 with heated seats and a heated steering wheel.
