Audi's ultra variant of its luxury saloon benefits from both a facelift and low emissions, offering company car operators significantly more appealing monthly costs. Key upgrades include a new 190 bhp 2.0-litre diesel and the adoption of a revised seven-speed dual-clutch transmission, which replaces the eight-speed CVT found in four-cylinder diesel A6s. The S line variant features xenon headlights, LED rear lights, sports suspension and larger 18-inch wheels compared to the standard SE model. The Audi impresses elsewhere on the road. It's easy to manoeuvre, despite its substantial size, while good visibility and standard-fit parking sensors means slotting into a space isn't a chore.
