The GT heralds the new generation of 5 Series models and this is reflected in the high class interior. Quality is superb, even by BMW standards, and all the buttons and switches feel upmarket. The design is bold, especially the large expanse of solid trim that spans the dashboard, yet the main controls are still simple to use on the move. The unusual stubby gear lever looks odd but is even easier to use than a normal automatic, while the electric parking brake frees up space on the high-placed central console.

The main stereo and sat nav (where fitted) functions are controlled through the iDrive dial, next to the gear lever. The system works well, but can take some getting used to initially. Thankfully the air conditioning controls are more traditional buttons and there are also switches on the steering wheel for controlling the stereo and trip computer.

One great feature is the head-up display. It’s an optional extra and not very cheap, but it is very useful and projects the speed, as well as sat nav and trip information, onto the windscreen, so you don’t have to take your eyes off the road.

At five metres long, BMW 5 Series GT comfort levels are surprisingly good because there’s serious amounts of rear passenger room – in fact it’s spacious enough to rival luxury limousines with enough room for even the tallest of passengers to stretch out. In SE models there are three seats in the back, but in reality it’s much better suited to two, helped by the wide armrest that folds down from the central seatback.

The two outer seats also slide forward and back plus they can be reclined, ideal for a relaxing snooze on long journeys. Executive models come with a four-seat layout. The ride is excellent and there’s barely any noise – either road or wind – even at motorway speeds. As you’d expect on a top BMW the seats are incredibly cosseting yet also supportive, although lumbar support is only standard on Executive models and optional on the SE.
