The Peugeot 408 is a distinctive "C-segment fastback" that merges attributes of hatchbacks, SUVs, and four-door coupes, aiming to occupy a niche within Peugeot's lineup. Its design recalls iconic Peugeot models from the past while introducing modern fastback characteristics seen in vehicles like the Polestar 2 and Kia EV6. Despite its unconventional categorization, the 408 boasts a mix of features, such as plug-in hybrid powertrains, to appeal to a diverse audience.
