The BMW 1 Series M135i five-door is a premium performance hatchback, compact for town driving but polished for longer journeys. In the UK it sits above family hatchbacks, rivaling hot Audi A3 and Mercedes A-Class versions. Its 3.0-litre engine, 326bhp, navigation and six-speed manual make the 2015–18 model a distinctive, driver-focused choice. It suits enthusiasts who want everyday practicality, not a two-seat sports car: five doors and useful rear seats help with commuting, shopping and family trips. The strong engine brings brisk acceleration and an engaging drive, while the premium cabin and compact size balance excitement with usability. Against rivals, it stands out for six-cylinder character in a versatile hatchback. Expect running costs and fuel use to exceed those of modest 1 Series models.
