The interior layout, fit and finish
If there’s one area where the BMW 4 Series does feel just like the BMW 3 Series it’s the interior. The driving position, for example, is almost identical, as are the dashboard and infotainment system.
In many ways, that's great news. Okay, you could be behind the wheel of an executive saloon, but a very good one, with a comfortable and supportive driver’s seat (as long as you add optional adjustable lumbar support) and lots of adjustment. If you want a sporty feel, you’ll probably also appreciate the fact that you sit closer to the road than in the Audi A5.
