- BMW Neue Klasse vehicles will get four superbrains, starting with the new IX3 electric SUV.
- Driving and feeling of superbrains control, autonomous driving, infotainment and other functions.
- Intelligent electronic fuses replace traditional fuses to improve power distribution and increase efficiency.
Last month, BMW presented the Neue Klasse Vision vehicle to us – an overview of what to expect the technology of the next range of new generation electric vehicles from the German brand. One of the features at the head of the Vision vehicle technology was the superbrain “Heart of Joy” which controlled how its future electric vehicles drive and feel.
Quick advance so far, and BMW has unveiled three additional control units for the next IX3, which was confirmed today for the beginnings in September. These will all be part of a brand new “digital nervous system” to supply each model Neue Klass. With the heart of joy, a superbrain will be dedicated to autonomous driving, another will manage the panoramic Idrive of BMW (AKA, infotainment), and a third party will manage the remaining auxiliary functions, such as lighting and climate.

To get there, BMW has piled up an incredibly powerful central computer system in their new generation cars, saying that it is 20 times more powerful than what is in their current range. They also thought considerable in the wiring that connects these digital brains.
Enter their “zonal wiring beam architecture”, essentially a way of saying that they have simplified the internal wiring of the car by dividing it into four zones: front, center, rear and roof. The result? A reduction of 600 meters of wiring and a saving of 30%. Less in bulk, more efficiency.

In addition to strengthened IT, BMW also replaces 150 traditional fuses with something to “ intelligent ” digital. They are not only fantasy circuit breakers; They actively manage energy distribution to improve energy consumption by 20%. In other words, your BMW will be smarter at the moment and the place where it uses power – whether driven, parked or loaded. Welcome to the world of intelligent energy management.
In addition to that, BMW goes all on live software updates. With more than 1,000 software modules, 20 GB of software and 500 million amazing lines of code, future BMW will mainly be vehicles defined by software. This means more to wait for the dealer to install the latest updates; Your car will simply upgrade.
For the future, BMW’s long -term strategy is to continue to develop internally where it matters – such as dynamics and infotainment – but associate with high -level software companies for less defining technology. They also built a software development center with more than 10,000 engineers, ensuring that they remain ahead of the game.
