The Performance Line trim makes the appearance of the DS4 a little more sporty, with 19in alloy wheels and black window surrounds and DS badges. You also get a Alcantara suede and leather interior, front parking sensors, a rear-view camera and a pressed carbon fibre insert on the steering wheel that is unique to each car. Like the entry-level Bastille + trim, you don’t get built-in sat nav, head-up display or the additional small touchscreen.
