- The BMW 4 Series has been the name of the coupe and convertible versions of the 3 Series (D-segment) since 2013. Since that date, the 4 Series range has been developed with the introduction of a sedan named the Gran Coupé. The current range of BMW 4 Series therefore today is made of three models, but it is not certain that the Gran Coupe version will be renewed.

- The 4 Series coupe is already being renewed in 2020. The new model is further distinct from the 3 Series than the older generation. The new 4 Series coupe displays its own personality with a large grille and a profile that evokes the 8 Series coupe. The convertible version of the 4 Series should be launched in 2021.

- Compared to the current 4 Series coupe, the new has its length increased to 4.76 m (+12 cm) and its wheelbase increased to 2.85 m (+4 cm). The 4 Series Coupe has two petrol engines (4 cylinders 420i of 184hp and 6 cylinders 440i of 374hp) and a diesel engine (4 cylinders 420d of 190hp). Another diesel (6 cylinders 430d of 286hp) will be available from March 2021. It will be followed by the 6-cylinder 440d of 340hp.

- The Gran Coupé is not sure to be renewed, because BMW has announced the soon launch of the i4 sedan (early 2021) which takes up the philosophy of the 4 Series Gran Coupé but in a 100% electric engine. This model could replace the 4 Series Gran Coupé and would become a competitor to the Tesla Model 3. It is for this reason that Inovev plans 100,000 units per year of the new 4 Series removed from the Gran Coupé version.
