The 508 follows Peugeot’s trademark i-Cockpit layout, where analogue dials are replaced by a 12.3in customisable digital display which is viewed over, rather than through, an unusually small steering wheel. Unfortunately, while this works well in the 3008 and 5008, in the lower-slung 508 it can be difficult to see the digital dials unless you have the steering wheel set lower than feels natural.
Some people will also struggle to get comfortable in the oddly shaped front seats, despite the wide range of adjustments on offer. These adjustments are electrical in Allure-spec cars and above.
Another advantage of Allure spec is that it brings a larger touchscreen infotainment display (10.0in rather than 8.0in), although the system it controls is no less laggy to respond to your commands, and its menus are just as illogically structured. On the plus side, sat-nav, Apple CarPlay and Android Auto are standard, while options include wireless smartphone charging and a punchy Focal stereo.
Fit and finish are generally impressive; the dashboard and surrounding areas make good use of soft-touch materials and eye-catching trim inserts, while top-spec GT models are set apart by high-quality stitched leather surfaces. The cheaper-feeling plastics used on the doors let the side down a bit, though.
Rearward visibility is a little restricted due to the 508's slinky exterior lines, so you'll be glad that reversing sensors are standard on all models. Front sensors and a rear-view camera are added on Allure trim and above, too. Thick front pillars and small side windows conspire to make forward and side visibility a little awkward as well, particularly when approaching roundabouts and T-junctions.
