How does the "Heart of Joy" high-performance computer optimize the vehicle handling of the 2027 BMW iX3?

One of four superbrains in the electronics architecture of the Neue Klasse, the Heart of Joy looks after drivetrain and driving dynamics management. This high-performance control unit is responsible for the drivetrain, brakes, energy recuperation, and steering functions, and processes information up to ten times faster than conventional control units. In this way, the potential of electric mobility in terms of instantaneous power delivery, smooth power transfer, agility, stability, and efficiency is fully realized. 
 
Together with the BMW Dynamic Performance Control software stack developed fully in-house, the Heart of Joy calculates all the driving dynamics parameters with a new level of speed and precision. The driver and passengers in the new BMW iX3 experience a uniquely harmonious and BMW-typical driving sensation whatever the situation. Every movement of the accelerator, brake pedal, and steering is executed directly and with assurance and precision. Supreme traction and – thanks to the unique Soft Stop function – the smoothest stopping process ever achieved by a BMW are among its other attributes. In addition, the efficiency of the new BMW iX3 is optimized by the integrated management of drivetrain, braking system, and energy recuperation. In everyday driving, 98% of braking maneuvers are carried out using recuperation only, without application of the friction brakes. The only occasions these are called upon are under emergency braking and during extremely sporty driving. 
 
The BMW iX3 can be guided through corners with exceptional accuracy. The Heart of Joy ensures fewer control inputs are required, and the iX3 holds a more precise and stable line. In this way, the BMW iX3 develops consistent, repeatable cornering behavior and can be steered more smoothly and intuitively.
