The Peugeot 508 has made significant strides in competing with premium car brands. The fit and finish inside the cabin are impressive and could easily be mistaken for a premium brand. The Peugeot i-Cockpit layout with its small, squared off steering wheel is unique and gives the car a distinct look.

The infotainment system in the Peugeot 508 is derived from the one in the 308 hatchback. It features physical shortcut controls and includes heating, ventilation, and Tom Tom navigation. The system is easy to use and the navigation display is clear and detailed. The lane keeping system can be turned off through the infotainment menus.

Apple CarPlay and Android Auto come standard in the Peugeot 508, and wireless device charging is available on certain trim levels. The car also comes with USB-A and USB-C charging ports.

The cabin design is ergonomic, although some drivers may find that the wheel positioning obstructs their view of the instrument screen. The second-row cabin space is slightly smaller than average for the mid-sized executive saloon class, but the boot space is competitive.
