The electric BMW i4 combines BMW's legendary sporty handling, elegant design, uncompromising quality and Gran Coupe practicality.
Design.
The exterior of the new BMW i4 is characterized by elegant proportions and a decidedly sporty character. The long wheelbase, combined with short overhangs and a sloping roofline, creates a squat silhouette. Frameless doors and slim roof pillars not only improve visibility, but also enhance the driving experience of a BMW sports car.
The body of the BMW i4 is carefully thought out in terms of aerodynamics. Every element, from the front bumper to the tailgate spoiler, aims to improve aerodynamic performance. BMW designers and engineers have paid attention to even those surfaces that are not visible to the eye in everyday use. For example, the high-voltage battery housing, engine compartment protection and aerodynamic suspension pads form a flat plane with seamless transitions. The rear diffuser effectively directs the air flow coming out from under the bottom.
An active air damper at the bottom of the radiator grille, which has 10 steps of adjustment, helps to reduce aerodynamic resistance. Special Air Curtains on the edges of the front bumper direct the air flow along the wheels. In addition, the optional BMW Individual wheels are further optimized in terms of aerodynamics by means of special inserts between the spokes.
The entire package of aerodynamic improvements delivers energy savings that translate into approximately 10 kilometers more range on a single charge, according to the WLTP test cycle. The drag coefficient of the electric BMW i4 is only 0.24.
The narrow LED headlights of the BMW i4 come as standard and are complemented by U-shaped elements for daytime running lights. As an option, adaptive BMW Laserlight headlights are available, which increase the beam range to 500 m at speeds above 60 km/h. BMW Selective Beam is available as an option.
A spectacular branded grill hides built-in cameras and ultrasonic sensors. As standard, the BMW i4 features BMW i Blue accent colors on the grille, side sills and diffuser elements.
The exterior design of the BMW i4 M50 and BMW i4 eDrive40 in the M Sport line emphasizes the sporty character of electric vehicles. The M Carbon exterior package and branded accessories from the M Performance range extend the scope for maximum customization.
A feeling of spaciousness is provided by the optional 0.33 m2 glass roof panel, which features an electrically operated lift-and-slide mechanism and extends to the rear of the roof. The electrified blind allows you to control the amount of sunlight and fresh air entering the car interior.
Interior features.
The interior of the BMW i4 integrates driver-focused controls and an ambience of premium luxury for all passengers. The driving mode selector, BMW controller and function keys on the center console are combined into a single stylish cluster.
As standard, the BMW i4 offers acoustically comfortable glazing, interior preheating and air conditioning and sports seats that provide optimum lateral support. The rear door is equipped with an electric drive, and the volume of the luggage compartment varies from 470 to 1290 liters.
Optionally available are electrically adjustable seats with memory function, active seat ventilation for the driver and front passenger, and heated front and rear seats. In addition to cloth and Sensatec, customers can choose from Vernasca leather upholstery as well as BMW Individual Merino extended leather upholstery and BMW Individual Merino full leather upholstery.
Intelligent climate control takes into account the number of passengers and their location in the cabin. You can now control the automatic climate control using the touch screen or voice commands. The system regulates not only the amount of incoming air and its distribution, but also controls the heating and ventilation of the seats.
Key characteristics.
The fifth-generation BMW eDrive powerplant consists of an electric motor, transmission and power electronics, which are combined in one housing and supplemented by a high-voltage battery. Electric motors work on the principle of a synchronous motor, in which the excitation of the rotor is not caused by permanent magnets, but by a precisely controlled supply of electricity.
At launch, two versions of the electric model will be available – the BMW i4 eDrive40 and the BMW i4 M50. Modification of the BMW i4 eDrive40 with a capacity of 340 hp. and a torque of 430 Nm is equipped with a classic rear-wheel drive. Acceleration from 0 to 100 km/h is 5.7 seconds, and top speed is electronically limited to 190 km/h. A fully charged battery provides a range of up to 590 km in accordance with the WLTP test cycle.
The BMW i4 M50 is the first all-electric model in the history of BMW M GmbH. It is equipped with all-wheel drive and a 544 hp power plant. with a maximum torque of 795 Nm. The range on a single battery charge is up to 510 km in accordance with the WLTP test cycle.
The most dynamic model in the BMW i4 range is equipped with two electric motors, one for each axle. The engine that drives the rear wheels develops a maximum output of 313 hp, while the output of the front axle engine is 258 hp. Intelligently matching the operation of both electric motors ensures stable movement and continuous acceleration even in the most adverse weather conditions.
The variability of engine operating modes allows you to distribute power and traction between two axles in any combination you need - from a fully rear-wheel drive mode to a mode that provides traction on all four wheels for the maximum possible traction.
Another interesting feature of the BMW i4 M50 is the Sport Boost function, which further emphasizes the sporty character of the model. The Sport Boost function is available in the Sport driving mode and allows you to briefly increase the output of the power plant by 50 hp. and 65 Nm - up to a maximum of 544 hp. and 795 Nm.
Peak power mode is available for more than 10 seconds, and acceleration is accompanied by an impressive BMW M-style sound effect. Sport Boost can be activated several times in a row, if the battery charge allows. BMW M fans will also appreciate Launch Control, which guarantees a perfect start from a standstill and gives the BMW i4 M50 an impressive 0 to 100 km/h time of just 3.9 seconds. Top speed is electronically limited to 225 km/h.
Chassis settings and characteristics.
All BMW's many years of sporting experience has been invested in the development of the power plant and chassis of the BMW i4. The high dynamic potential of the model went far beyond fast acceleration in a straight line.
The chassis design of the BMW i4 consists of a front double wishbone and a rear five-link suspension. Servotronic electromechanical steering, DSC dynamic stability control and rear axle air suspension are already available as standard equipment.
The BMW i4 M50 version is equipped with Adaptive M Suspension and M Sport Brakes. Torque distribution between the two electric motors is much faster and more precise than would be possible with a traditional transfer case located between the axles.
While the wheel slip limit function instantly eliminates loss of traction, DSC optimizes directional stability by selectively activating the brakes on each wheel. Dynamic Traction Control (DTC) provides higher levels of wheel slip, helping the driver to explore the limits of the vehicle.
For the most experienced drivers, the DSC off mode is intended, which does not allow electronic assistants to interfere with the operation of the brakes and gives the driver access to prolonged controlled drifts.
High voltage battery and recharge technologies.
The lightweight and efficient design of the power plant provides impressive dynamics and an impressive range without the need for large and heavy batteries. The battery of the latest BMW i4 consists of four 72-cell modules and three 12-cell modules. The total battery capacity is 83.9 kWh.
The architecture on which the BMW i4 is based was originally developed for an electric propulsion system. Power elements such as the front axle subframe and torsion bars are rigidly connected to the high-voltage battery housing.
The BMW i4 battery has an extremely low cell height of just 110 mm. Thanks to the location of the battery in the vehicle floor, the center of gravity of the BMW i4 is 53 mm lower than in the BMW 3 Series Sedan. This is the key to unparalleled BMW style precision handling.
The BMW i4 is equipped with an integrated heating and cooling system with heat pump function for the interior, high-voltage battery and powertrain. The BMW i4 heat pump system uses the thermal energy of the environment and the heat generated by the engines. At low outside temperatures, this results in a range increase of approximately 15% compared to conventional electrical systems.
In addition, predictive battery thermal management optimizes battery operating temperature before stopping at a fast charging station, making the battery charging process faster and more efficient.
Connecting to a regular household socket or Wallbox charger allows you to charge the high-voltage battery from both single-phase and three-phase AC mains with charging speeds up to 11 kW. Using this method, the BMW i4 can fully recharge the battery in less than 8.5 hours.
Installing the Combined Charging Unit gives you access to DC fast charging stations up to 200kW. At these stations, in just 10 minutes, the range of the BMW i4 eDrive40 can be increased to 164 km, and the range of the BMW i4 M50 to 140. In Europe, BMW Charging is also available with charging at public charging stations and powerful IONITY terminals at special rates .
In addition to the usual ways to recharge the battery, the BMW i4 uses adaptive brake energy regeneration. The intensity of the energy recovery can be adapted to the driving situation thanks to data from the driver assistance and navigation systems. For example, when approaching an intersection, the regeneration power can be increased using the slowdown effect, and on straight sections of the road, the coasting mode is activated. The maximum recuperation power is 116 kW for the BMW i4 eDrive40 version and 195 kW for the BMW i4 M50 version.
Digital environment and multimedia.
The BMW i4 is equipped with the next-generation BMW iDrive multimedia system with the BMW Curved Display, which consists of a 12.3-inch information display and a 14.9-inch multimedia display. The system is based on the new BMW 8 operating system, complemented by the BMW Intelligent Personal Assistant.
The unique BMW IconicSounds Electric soundtrack provides acoustic feedback when you press the accelerator pedal and pick up speed. Sound effects, created in collaboration with renowned composer Hans Zimmer, greatly enhance the driving experience of the BMW i4 electric vehicles.
The BMW Live Cockpit Professional is standard on the BMW i4 and includes a 100W audio system with DAB+ tuner and 6 speakers. Optional Hi-Fi speaker system with 10 speakers and up to 205W output power. And for the most sophisticated lovers of high-quality sound, there is a Harman Kardon surround sound system with 16 speakers and a 464 W digital seven-channel amplifier.
Remote software update technology allows you to install the latest digital features. In addition, data transfer in the new BMW i4 is carried out using a high-speed 5G network, which takes the car's online capabilities to a new level.
Driver assistance systems.
The list of driver assistance systems includes about 40 assistants. The BMW i4 comes standard with forward collision warning, speed limit warning and lane departure warning. Park Distance Control and a rearview camera are also offered as standard equipment.
The Driving Assistant Professional is available as an option and includes Steering and Lane Keeping Assist as well as Active Cruise Control with Stop&Go function.
The optional Parking Assistant includes Reverse Assist, while the Parking Assistant Plus adds Surround View and Remote 3D View.
The concept of sustainable development.
The new BMW i4 will be produced at the BMW Group plant in Munich. It is important to note that only environmentally friendly energy is used in the production of batteries for electric vehicles. At the same time, the entire life cycle of an electric vehicle, from resource extraction to disposal and recycling, is aimed at massively reducing CO2 emissions.
The special design of the motors avoids the use of rare earth materials, and the cobalt and lithium for the batteries are mined in the most sustainable and environmentally friendly way. The proportion of cobalt in the BMW i4 battery cathodes has been reduced to less than 10%. As a result, up to 90% of the materials in battery construction can be recycled.
