Chronology
PredecessorBMW 1 Series (E87)
SuccessorBMW 1 Series (F40)

For the second generation of 1 Series, the coupé and convertible models marketed separately using the new BMW 2 Series nameplate.

The F20/F21 was initially powered by inline-four petrol, inline-four diesel and inline-six petrol engines. In 2015, inline-three petrol and diesel engines were added to the model range. All engines are turbocharged.

Unlike most hatchback competitors, the F20/F21 uses a rear-wheel drive (rather than front-wheel drive) for most models. The F20/F21 is the first 1 Series to offer an optional all-wheel drive (called "xDrive" by BMW).

In July 2019, the BMW 1 Series (F40) began production as the successor to the F20.[5]

Equipment

edit
 
Interior

Available equipment includes satellite navigation with an 8.8-inch screen, iDrive, LED headlights and digital radio.[6][7][8]

The interior and exterior trim is either Sport Line, Urban Line or M Sport. These trim packages differ by alloy wheels, kidney grille, FDS, and other appearance-related features.[9][10]

In November 2015, the optional Automatic parking (called "Parking Assistant", where the car steers itself to parallel park) was upgraded.[11]

114-125 models with the M Sport trim and M Performance models can be fitted with M Performance Parts. These include black kidney grilles, sport brakes for 18 inch and higher wheels, side skirt ground effects, carbon fibre mirrors and an M Performance silencer system for the M135i and M140i.

The F20 five-door hatchback was the first of the F20/F21 body styles to be released. It was unveiled in 2011 at the Frankfurt Motor Show[12] and then the Auto Guangzhou motor show.[13]

Early models included the 116i, 118i, 116d, 118d, 120d.[14] In 2012, the 125i, 125d and 116d EfficientDynamics Edition models were introduced.[15][16] In July 2012, the 114i and M135i were introduced, followed by optional all-wheel drive (xDrive) for the 120d and M135i models. After the introduction of the facelift (LCI) models in 2015, the M140i replaced the M135i, which upgraded the engine to the BMW B58 and included various cosmetic changes.[17]

3-door hatchback (F21)

edit

The vehicle was unveiled at the Auto Mobil International Leipzig 2012.[18] The exterior styling was overseen by Nicolas Huet.[19]

The launch models consisted of the petrol-engined 114i, 116i, 125i and M135i models, and the diesel-engined 114d, 116d, 116d EfficientDynamics Edition, 118d and 125d models. The inline-six M135i model was unveiled in the 3-door body style at the 2012 Geneva International Motor Show.[20][21][22][23][24] From 2016, the M140i replaced the M135i, with same engine and options as F20.[25]
