The BMW 1 Series, a staple in BMW’s lineup since 2004, is a subcompact executive car that has evolved significantly through its three generations.

First Generation (E8x, 2004-2013)

The first generation of the BMW 1 Series, known as the E8x, debuted in 2004. It was available in various body styles, including hatchback, coupe, and convertible. This generation was rear-wheel drive, a rarity in the hatchback market segment, and offered a range of engines from four-cylinder turbo-diesel to six-cylinder turbocharged petrol. The E8x models were praised for their driving dynamics and sportiness, embodying BMW’s commitment to performance. Notably, the 1 Series M Coupé featured a turbocharged inline-six engine and a six-speed manual transmission, laying the groundwork for future M models.

Second Generation (F20/F21, 2011-2019)

The second generation, referred to as the F20/F21, was introduced in 2011. This generation saw the 1 Series continue with its rear-wheel drive setup but also offered an optional all-wheel drive (xDrive). The engine lineup included turbocharged inline-three, inline-four, and inline-six petrol and diesel engines. In 2015, the F20/F21 received a facelift, improving both performance and efficiency. The introduction of the BMW M135i in 2012 highlighted this generation’s commitment to high performance, featuring a 320 hp engine.

Third Generation (F40, 2019-present)

The current third generation, launched in 2019, shifted to a front-wheel drive platform with an all-wheel drive option, aligning with BMW’s UKL2 platform used by other models like the X1 and X2. The F40 1 Series is only available as a 5-door hatchback and emphasizes modern design, advanced technology, and efficient engines. The engine range includes three- and four-cylinder options, with power outputs up to 306 hp in the M135i xDrive model. This generation also features advanced driving assistance systems and a more driver-focused cockpit.

Notable Features and Changes

Throughout its evolution, the BMW 1 Series has maintained its reputation for sporty driving dynamics, efficient performance, and premium features. Innovations like the introduction of the iDrive system, advanced safety features, and the shift from rear-wheel to front-wheel drive (with the F40) have marked significant milestones in its development.

The latest generation continues to build on this legacy, offering enhanced comfort, connectivity, and driving pleasure. However, it remains to be seen how the future models will adapt to the changing automotive landscape, especially with increasing emphasis on electric vehicles.
