The PEUGEOT 508 FASTBACK (2018-23) 5DR FASTBACK HYBRID 1.6 PHEV 11.8KWH 225 GPF SS EU6 GT E-EAT AUTO8 is a sleek, five-door plug-in hybrid family car, sitting between mainstream hatchbacks and executive saloons. Its low, coupé-like shape gives it more road presence than a conventional hatch, while the rear hatchback opening keeps it practical.
