The BMW Group is opening a new chapter in its history with the unveiling of a pure-electric Gran Coupe. The BMW Concept i4 takes electric drive to the core of the BMW brand and heralds a new era in Sheer Driving Pleasure. The BMW Concept i4 represents a look ahead to the BMW i4, slated to enter production in 2021. It provides a whole new take on the dynamic excellence for which BMW is renowned and blends a modern, elegantly sporty design with the spaciousness and functionality of a four-door Gran Coupe – all while generating zero local emissions.
The drivetrain’s standout numbers include a range of up to 600 km (WLTP), output of up to 530 hp, 0 – 100 km/h (0 – 60 mph) acceleration of approximately 4.0 seconds and a top speed in excess of 200 km/h (124 mph). However, the driving qualities of the BMW Concept i4 cannot be expressed in figures alone. The virtually silent delivery of power creates an entirely new sensation of dynamism.
As part of the package, the Concept i4 includes several exterior and interior design elements which will make an appearance in both the BMW i4 and other electrically-powered production vehicles.
Fifth-generation BMW eDrive technology is a defining feature of the BMW i4 and therefore also of future electric mobility. The BMW iX3 due to go into production in 2020 will lead the way in the application of the new tech, which will be introduced in a number of electrically powered BMW vehicles – such as the BMW iNEXT and BMW i4. The electric motor, power electronics, charging unit and high-voltage battery using fifth-generation BMW eDrive technology are all-new developments enabling the BMW Group to take another significant step forward in the field of electrified drive systems. The electric motor developed for the BMW i4 generates maximum output of up to 390 kW/530 hp, which ranks it alongside a current BMW V8 combustion engine. Its instantaneous power delivery gives the BMW i4 standout performance attributes and exceptional efficiency.
The fifth generation of BMW eDrive also brings a newly designed high-voltage battery with the very latest battery cell technology. The version of the battery developed for the BMW i4 impresses with its extremely slim construction and optimised energy density. It weighs roughly 550 kilograms, has an energy content of around 80 kWh and achieves an operating range of up to 600 km in the WLTP cycle.
All in all, fifth-generation BMW eDrive technology sets new standards in terms of power density, efficiency and range in locally emission-free driving.
Series production of the new BMW i4 will begin in 2021 at the BMW Group’s main plant in Munich. This means that, in the future, combustion-engined vehicles, plug-in hybrids and all-electric vehicles will be manufactured on the same assembly line in Munich.
Integrating the BMW i4 into the existing production system represents a challenging task for Plant Munich. The body concept of the BMW i4 differs from the architectures of the vehicle models produced at the plant to date due to the need to accommodate its high-voltage battery. Approximately 90 per cent of the existing production equipment in the body shop can be incorporated into the process, i.e. adapted to manufacture of the i4. However, the remaining ten per cent – especially the machinery involved in building the rear structure – will need to be newly built.
A separate new piece of equipment will be fitted in the assembly halls for installation of the high-voltage battery, as the battery needs to be fitted in the car from below. A particular challenge in the conversion/installation process are the crowded structures of the assembly halls. Working within these tight confines, old machinery will have to be removed and new equipment installed and brought on stream within a six-week period. This requires long-term planning and precise implementation.
The company is investing a total of around 200 million euros in Plant Munich to bring series production of the BMW i4 to fruition.
