Car interiors are the focus of much attention right now. We want cabins that are smarter, more luxurious and more jam-packed with technology than ever before. Perhaps that's why so many car makers chose to display their future interior concepts at the Consumer Electronics Show in Las Vegas this week.

While naturally there were various takes on the future cabin theme, the main points are as follows. In just a few years' time, there will be almost no new cars launched with analogue dials. Instead, they'll feature an all-digital instrument cluster, more likely as part of a wider screen in front of the driver.

Of course, some of this technology is already here. The current Mercedes-Benz S-Class uses an all-digital dashboard, Audi's TT, Q7 and new A4 can all be bought with the firm's Virtual Cockpit and the new E-Class - now just days away from its debut at the Detroit motor show - allows drivers to customise the look of its digital dashboard using pre-set themes.
