What it sounds and feels like

In comfort modes the car remains civil and refined. Open the valves and the straight-through, non-res centre section delivers a deep, assertive exhaust note with crisp crackle on upshifts and a rich six-cylinder character that brings the B58 to life. It is a true sports tone without drone, engineered for everyday enjoyment and weekend fun.

Fitment notes

To achieve the correct quad-exit look, the original rear diffuser from the BMW G30 550i must be used.
