Economy is further assisted by a coasting function that allows the car to freewheel when you take your foot off the throttle. In the real world, this equated to economy of over 45mpg on our test drive without any special treatment.
With the suspension set to Comfort, the A4 proves a relaxing companion over long distances with little in the way of float or roll. No doubt the relatively small 18in wheels of our test car helped in that respect. We suspect the smaller optional 17s would take the edge off sharper ridges.
Should you want to cover ground quickly, the standard drive select system allows you to alter the throttle response, gearbox behaviour and stiffen the suspension. This makes the A4 feel a lot more lively; it needs a lot less throttle travel to get going and body control is noticeably tighter.
A passive Comfort suspension set-up is standard, but our car was fitted with an adaptable version of it. A Sport adaptive system is also available to firm things up even more, but we wouldn’t bother. This is by no means a sports saloon; it feels more like a shrunken luxury saloon and prefers to be driven in a gentle fashion.
At very low speeds, the front wheels can struggle to put down all the available torque. This manifests itself as a flashing traction control light when the aid is switched on, or as a fair bit of thumping as the front axle hops with it off. As you’d expect, wet weather exacerbates this shortcoming.
At least there’s little to no writhing from the steering wheel when this happens. As we've come to expect from the A4, precious little feedback is sent through the steering column during hard cornering.
Where this car makes the most sense is on motorways and dual carriageways. At speed, the V6 proves wonderfully flexible, allowing the A4 to surge forward should you want to build speed rapidly. You get the distinct impression it would be just as comfortable at triple-digit Autobahn speeds, too.
In the cabin things are predictably good. There’s plenty of room for four adults, although getting three on the rear bench is a bit of a squeeze. Headroom is good, and all the cabin materials are of a typically high quality. The boot is a decent size, too, and it's comparable to its main competitor the BMW 3 Series.
