With the new BMW i4, BMW seeks an optimum balance from a range of disciplines so as to create a car that has the renowned handling characteristics of a BMW.

25 Jan 2021 | International News : Germany



When an ideal balance is called for between dynamics and ride comfort, the BMW 3 Series and 4 Series models consistently set the benchmark within their segments in the premium market. In terms of electrically powered vehicles, the new BMW i4 is set to take on this role very soon. The first all-electric 4-door Gran Coupe enriches locally emission-free mobility with sheer driving pleasure.

With a few months left before its world premiere, the BMW i4 is currently completing the final phase of driving dynamics testing.

BMW's goal is to make the i4 into a well balanced performance machine without sacrificing ride comfort
The focus here is on the integrated application of all drive and suspension components, ensuring that the spontaneous power delivery of the electric motor is combined with precisely controllable handling in every situation, fascinating cornering dynamics, optimised traction in all weather and road conditions and perfectly balanced ride comfort.

For the purpose of this fine-tuning process, the BMW Group applies its technological expertise in the areas of drive and suspension drawn from decades of experience. This gives the new BMW i4 a mature premium character and makes for a driving experience that is unique within the competitive environment.

With a maximum output of up to 523bhp, the electric powertrain in the BMW i4 enables impressive acceleration manoeuvres. It accelerates from zero to 100km/h in four seconds. But even more impressive than its pure sprint capacity is the driving response it conveys.

A model-specific damper technology reduces the dipping movements of the body at the moment of set-off, while the actuator-related wheel slip limitation developed by BMW with its extremely fast and precise control guarantees optimum traction and performance. 

The i4 sends power to all four wheels, allowing for a 0-100km/h acceleration time of just four seconds
Other distinguishing features of the i4 include its spontaneous reactions to every movement. The prerequisites for this high level of agility and precision are anchored in the underlying vehicle concept of the BMW i4. This includes the car's long wheelbase, wide track widths, model-specific camber values, large wheels, as well as the high torsional rigidity and the vehicle's low centre of gravity and weight balance.

The design and tuning of the suspension and damping systems consistently ensure optimum road contact. At the same time, the virtually silent drive, in combination with the sophisticated suspension technology, gives the impression of an effortlessly floating vehicle even at higher speeds, entirely unaffected by bumps in the road or difficult traction conditions.

The BMW i4 is effortlessly controllable, even in highly dynamic driving situations. In addition to its neutral self-steering behaviour and its powerful, precisely controllable brakes, the steering in the BMW i4 is a major contributing factor here.

BMW aims to tune the i4 into a powerful yet very controllable vehicle, so as to provide maximum driving pleasure at all time
It responds directly and with a high degree of accuracy, offering the driver precise feedback at all times while remaining entirely independent of drive forces, even during intensive acceleration or deceleration. 

The distinctive driving dynamics of the BMW i4 derive partly from the fact that its performance characteristics are not achieved at the expense of driving comfort. The purely electrically powered Gran Coupe is characterised by unrestricted suitability for day-to-day use.

Relaxed driving over long distances is ensured by the power steering and the fact that the i4 is largely insusceptible to any disruption caused by road bumps.

Fitted with a high-voltage storage system featuring the latest battery cell technology with a range of 600km, the chassis technology of the BMW i4 is designed for long-distance comfort, too. It is based on the high-quality damper technology, supplemented with model-specific components and separately tuned. This effectively reduces body vibrations due to road unevenness and on bends.

At the same time as the final calibration runs are being held, preparations are underway for the production start-up of the new BMW i4 at BMW Group Plant Munich.
