Plush materials, slick design and a user-friendly media system make the A5 Sportback a superb place to while away seemingly endless motorway trips. All the materials feel tactile and solid and the design – closely related to that of the A4 – seems somehow more upmarket in this low-slung four-door coupe with its sleek roofline.

There’s a choice between large, clear analogue dials and a fully digital ‘virtual cockpit’ in its place – which lets you customise the display, for instance with a large sat-nav map and small speedometer and rev counter. Whether you pay extra for the latter or not, the main instruments are easy to read on the move, with simple steering wheel controls that make it easy to navigate between trip computer, phone, radio and navigation displays among others.

The central media system, is similarly accessible, thanks to a rotary control at the base of the gearlever and logically arranged menus. The row of horizontal switches for the climate control system is a bit trickier to use, however, as it’s hard to get the right button by feel, but this is rarely problematic.

With comfy seats, compliant suspension and very little wind, road or engine noise making itself heard inside – in both petrol and diesel form – the A5 Sportback is a very comfortable car. Choose a model with 17-inch alloy wheels fitted and the ride is particularly luxurious, making for a great car for passengers and driver alike.

We also found the optional sports seats very comfortable, with good back and side support. Throw in the S Tronic automatic gearbox and the A5 is a very relaxing car to drive, capable of absorbing the bumpiest of country road without fuss.

Models fitted with 19-inch alloy wheels and less rubber between driver and the road provide a noticeably firmer ride, though it should still prove more than comfortable enough for most drivers. Specify the optional Damper Control suspension and the picture is better, with a bit more give in the suspension and greater ability to soak up bumps, if you steer clear of the firmer Dynamic mode.

The large wheels do throw up a lot of extra noise, however. Step up to the S5 Sportback and you get more driver-focused sports suspension. While firmer than the other models, it’s not much worse than other A5s with large alloy wheels and the car is mostly unfazed by big bumps.
