The BMW 1 Series is a range of premium compact hatchback cars produced by BMW since 2004. It is positioned in the subcompact executive car segment and has evolved through four generations, with the current model launched in 2024. The line has served as BMW’s entry-level model in many markets and is closely associated with the Audi A3 and Mercedes-Benz A-Class.

History

The 1 Series was introduced in 2004 as BMW’s compact hatchback and successor to the 3 Series Compact. Over time it moved through several generations, with the fourth generation arriving in 2024.

Design and layout

Early 1 Series models were notable for rear-wheel drive, while the third generation switched to front-wheel-drive-based architecture. The current generation continues with front-wheel drive for most versions, with xDrive available on higher-performance trims.

Powertrains

The current European/UK line-up is centered on petrol engines with mild-hybrid assistance, and BMW’s 2024 update removed manual transmissions from the range. Higher-performance M135 versions use all-wheel drive and more powerful turbocharged engines.

The BMW 1 Series occupies the premium compact hatchback segment and is commonly compared with the Audi A3 and Mercedes-Benz A-Class. It is aimed at buyers wanting a small BMW with premium features and brand identity.
