The interior layout, fit and finish
A supportive, electrically powered driver’s seat with four-way adjustable lumbar support is standard, as is plenty of steering wheel adjustment, so finding a decent driving position will be easy for most drivers.
The view straight ahead is good, too, thanks to slim windscreen pillars and bright LED headlights, which help you peer far into the dark at night. And while the A7’s sloping roofline is a limiting factor when looking back over your shoulder, it's easier to see what's behind you than it is in a CLS. In any case, all models come with front and rear parking sensors and a reversing camera.
As touchscreens go both are good, with razor-sharp graphics and quick responses – but they are quite distracting to use on the move. That's because, despite haptic feedback that confirms your selections, you have to look away from the road, find the right icon and guide your finger to it.
Ultimately, the rotary-dial controlled iDrive system in the BMW 6 Series GT lets you keep your eyes on the road more often. On the plus side, all A7's come with in-built navigation, a DAB radio, Bluetooth, and Apple CarPlay/Android Auto smartphone mirroring as standard.
We do like Audi’s Virtual Cockpit digital instruments behind the steering wheel. These are standard on every A7 and, again, the screen is super sharp. The system allows you to customise the information you’d like to see really easily, using the handy steering wheel buttons.
