The heart of the BMW brand beats in the premium segment of the mid-range category. Along with the BMW 4 Series Coupé, BMW 4 Series Convertible and BMW 4 Series Gran Coupé models, it is the BMW 3 Series that brings out the qualities that are key to hallmark brand driving pleasure in a particularly concentrated form.
Now BMW is transferring the brand’s characteristic core features to the age of electric mobility – the central purpose in developing the BMW i4.
The BMWGroup’s first purely electrically powered model for the premium mid-range combines driving dynamics, sporty and elegant design, premium quality and the spacious comfort and functionality of a four-door Gran Coupé with locally emissions-free mobility. This heralds a new era of driving pleasure.
The future of electric mobility will be shaped by fifth-generation BMW eDrive technology, for which the BMW iX3 – to be produced from 2020 – will act as a pioneer, followed by the BMW iNEXT and the BMW i4.
With fifth-generation BMW eDrive technology, which also includes the latest innovations in the field of battery cells, the BMW i4 sets new standards in sporty performance, achieving a range of some 600 kilometres. 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.
The electric motor developed for the BMW i4 delivers a maximum output of around 390kW/530hp, reaching the level of a V8 engine in current BMW models fitted with a combustion engine. Its spontaneous power delivery gives the BMW i4 outstanding performance characteristics and exceptionally high efficiency.
The fifth generation of BMW eDrive also includes a newly designed high-voltage battery featuring the latest battery cell technology. The design of the high-voltage battery developed for the BMW i4 is characterised by its extremely flat design and optimised energy density. With a weight of some 550 kilograms, it has an energy content of around 80kWh.
The all-electric BMW i4 will be produced from 2021 and subsequently launched on the global automotive markets. The new model will be manufactured at the company’s main plant in Munich, where other vehicles produced include the BMW 3 Series Sedan with conventional combustion engine and plug-in hybrid drive, the BMW 3 Series Touring with conventional drive and from summer 2020 also with plug-in hybrid drive, the BMW 4 Series Coupé and the BMW M4 Coupé (fuel consumption combined: 10.0–9.3l/100km; combined CO2emissions: 227-213 g/km).
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. Here, the experience gained from development of the previous generations of BMW eDrive technology is consistently tapped into with the aim of optimising all components on an ongoing basis.
Fifth-generation BMW eDrive technology comprises a highly integrated drive system in which the electric motor, transmission and power electronics are accommodated in a single housing. This drive system is compatible with all vehicle concepts and will be available for different models in a range of output levels. It also allows a significant increase in power density as well as a reduction in weight and manufacturing effort.
