THE BMW i4 – effectively an electric BMW 4 Series Gran Coupé – is due to have an electric driving range of around 370 miles and it will be here in 2021. The electric BMW iNEXT is also due in 2021, but the BMW iX3 will be here first, in 2020.
The BMW Group currently has the biggest range of all-electric and plug-in hybrid models, and by 2023, the BMW Group will have 25 models with electrified drive.
BMW claims that the drive technology of the BMW i4 sets new standards in terms of power density, efficiency and range in locally emissions-free driving. The electric motor, power electronics, charging unit and high-voltage battery have been entirely newly developed. Together they form the BMW eDrive technology of the fifth generation, with which the BMW Group has made further significant advancements in the field of electrified drive.
From 2020 onwards, fifth- generation BMW eDrive technology will be introduced first in the BMW iX3 and then in the BMW iNEXT and BMW i4. The electric motor developed for the BMW i4 delivers a maximum output of around 390 kW/530 hp, reaching the level of a V8 engine in current BMW models fitted with a combustion engine.
The fifth generation of BMW eDrive also includes a newly designed high-voltage battery featuring the latest battery cell technology, characterised by an extremely flat design and optimised energy density. With a weight of around 550kg, it has an energy content of around 80 kWh, and will result in the BMW i4 having a 0-62 mph acceleration time of around 4.0 seconds and a top speed of more than 124 mph.
The electric drive component of the BMW i4, its charging unit and high-voltage battery are all developed in-house by the BMW Group. Production is carried out in-house or according to BMW Group specifications.
Production of future-generation electric motors will no longer require materials categorised as rare earths.
The next generation charging unit is designed for a charging capacity of up to 150 kW. This allows the high voltage battery of the BMW i4 to be charged to around 80 per cent of its full energy content in around 35 minutes. This results in a charging time of around six minutes for a range of 60 miles.
