What is it?
Some versions flaunt modest dashes of extra brightwork, while inside the instruments appear on a digital, reconfigurable screen and there are detail decor improvements. Equipment improves with the standardisation of Business Navigation (about time) Bluetooth connectivity (ditto), a USB port and xenon headlights.
And the infotainment system’s capabilities can be deepened with an i-Drive controller that doubles as a mouse, and facilities for dictating texts and emails. Later this year there’ll be an optional self-parking system requiring no control inputs of any kind, and a traffic jam assistant allowing the 5 Series to steer, accelerate and brake with no intervention from the driver at up to 19mph. Which is probably just as well given that the mouse also allows web surfing.
