The Peugeot 508 saloon, SW estate and RX models will all be mildly facelifted and on sale in June. Revisions to the exterior are limited to 308-style headlights and some splashes of chrome around the headlights and grille. Inside, there’s little changed too other than some trim improvements. However, the 508 will benefit from Peugeot’s BlueHDi diesel engines that should see the 508 offer sub-100g/km CO2 emissions and increase fuel economy further. These engines will also meet EU6 emissions regulations.
