It seems that none of the current challenges that the automotive world is facing could prevent BMW from shocking the world with its latest electric vehicle -- the new BMW i4. With its much-awaited debut on the horizon, the i4 is now completing the final phase of driving dynamics testing meant to calibrate its inherent qualities.
Engineering The BMW I4 To Be Quick, Agile And Precise
BMW gave the i4 a powerful electric powertrain that delivers up to 523 hp (390 kW/530 PS) of output, allowing the EV to zoom from nil to 62 mph in just around 4 seconds. Nonetheless, BMW didn't engineer the i4 just for acceleration prowess but also for driving response. BMW wanted the i4 to offer quick and precise control,unaffected by drive slips or course corrections.
Key to this are elements such as a model-specific damper technology, speed-related Servotronic power steering, as well as an actuator-related wheel slip limitation (ARB) system. The EV also features a long wheelbase, wide track, large wheels, high torsional rigidity, low center of gravity and model-specific camber values. All of these help ensure the new i4 is stable, quick, agile and precise.
Striking A Balance Between Performance And Comfort
BMW's goal for the new i4 electric Gran Coupé is to strike a distinct balance between sporty flair and ride comfort, not sacrificing one aspect for the other. To this end, the new i4 comes is designed to be suitable as a daily driver. It's powerful and yet still gives an impression of an effortlessly cruising vehicle unaffected by road bumps or difficult traction conditions.
To ensure potent performance, the i4 comes installed with a high-voltage storage system with battery cell technology allowing for a range of up to 372.8 miles (600 km) on the European WLTP cycle. To ensure great comfort, the i4's chassis technology features suspension and damping systems designed and tuned to reduce body vibrations while maintaining optimum road contact.
Validating All Goals Before Global Debut
Nevertheless; nothing is final for the new BMW i4 until all goals are validated. The final calibration runs are meant to ensure that everything is as expected. From power, cornering and control to ride comfort, the i4 is currently being fine-tuned so it can finally receive BMW's final stamp of approval.
The i4 is currently expected to start production in November 2021.
