Heart of Joy
Powerful computing genius.

  • The new Heart of Joy central computer combines control of the drivetrain, brakes, energy recuperation and other subfunctions in a single device. 
  • It processes information ten times faster than previous systems with separate control units and control algorithms for the drive system and brakes.
  • This minimises braking manoeuvres and makes optimum use of the full potential of the electric drive system.
  • The result is a smooth, dynamic driving experience at an unprecedented level – the redefinition of Sheer Driving Pleasure.
Software

BMW Dynamic Performance Control.

  • The BMW Group developed the software for the Heart of Joy in-house. We call it BMW Dynamic Performance Control.
  • The system enables high-precision, composed, smooth handling, as well as optimum driving dynamics – particularly when cornering.
  • Symbiotic Drive combines with the driver assistance systems to create a completely new driving experience. Whenever the driver wants to accelerate, brake or steer, their inputs merge seamlessly and intuitively with AI-enabled software.
Energy efficiency

Even greater range.

  • Another strength of the Heart of Joy is the significantly improved energy efficiency through the intelligent linking of the drive system, brakes and energy recuperation.
  • Brake energy recuperation carries out almost all braking manoeuvres in everyday driving. The conventional friction brakes need to be applied in emergency situations only. 
  • Energy recuperation creates a symbiosis between the drive and braking functions, which the Heart of Joy controls to optimum effect – with the result that vehicle efficiency improves by up to 25 per cent. This plays an important role in increasing the car’s range even further.
