For all the avant-garde features, such as dials that change colours and your choice of polyphonic alert sounds, the basic engineering of the C4 is conventional in the extreme.
Citroën’s ever expanding double-chevron grille splits enormous front headlamps that can be specified with some of the best bi-xenon lights we’ve tried. They offer great light dissipation, but corner lights are already standard on other models.
Over-the-shoulder visibility could be rather better than it is with slimmer C-pillars, although small rear quarterlight windows do help. A blind spot monitor — part of the optional visibility pack — makes use of the parking sensors in the rear bumper to save money. Clever.
The rear wiper seems ridiculously small and only wipes a small proportion of what is already a hardly generous rear screen.
