Superb, in a word. The S is an incredibly polished and accomplished grand tourer, effortlessly covering ground at serious pace while both entertaining the driver and cosseting the passengers. Key to this appeal is the manner in which its suspension masterfully balances excellent body control with a perfectly judged compliancy. The S flows and breathes over the road, irrespective of its surface or topography. It's the ride quality that Audi chassis engineers, and their hard-working chiropractors, would kill to achieve. The steering is a driver's delight. Quick-witted, chunkily weighted and chatty, it constantly informs your palms about both road conditions and grip levels. There's a wonderful connectedness about the way the slightest tweak of the wheel has the Jaguar's nose peeling immediately and cleanly into corners, helped by a chassis that never feels anything but balanced and composed. This is a car born to sew together a string of challenging curves with consummate ease.
