Infineon Technologies AG Powers BMW Neue Klasse Software-Defined Vehicle Architecture

On February 16, Infineon Technologies AG confirmed its role in advancing the BMW Neue Klasse through its contribution to the platform?s software-defined vehicle architecture. The company will also present the BMW iX3, the first model built on the BMW Neue Klasse platform, during its Annual General Meeting. This collaboration highlights how BMW Neue Klasse is redefining vehicle electronics with scalable systems, centralized computing, and software-led functionality designed to adapt quickly to evolving customer expectations and regulatory requirements.

BMW Neue Klasse Built on Scalable Software-Defined Vehicle Architecture

The BMW Neue Klasse introduces a scalable electronic foundation engineered to support next-generation mobility. Infineon Technologies AG supplies semiconductor solutions that power computing, connectivity, and energy management within this software-defined vehicle architecture.
Through this architecture, BMW Neue Klasse enables seamless over-the-air updates, allowing new features and performance enhancements without physical hardware modifications. As a result, BMW Group can respond more rapidly to customer needs and regulatory changes while maintaining long-term platform flexibility.

Central ?Superbrains? Drive Core Functions

At the core of BMW Neue Klasse are four centralized high-performance computing units known as ?Superbrains.? These units consolidate functions that were previously distributed across multiple control modules, improving efficiency and system coordination.

?Heart of Joy? High-Speed Control System

One of the four Superbrains, called the ?Heart of Joy,? manages critical driving functions including acceleration, braking, and steering within a unified high-speed control system. This advanced controller operates using microcontrollers developed by Infineon Technologies AG.
The remaining three Superbrains in the BMW Neue Klasse architecture oversee automated driving capabilities, infotainment systems, and essential vehicle operations. This centralized computing approach strengthens system integration while supporting future software scalability.

BMW iX3 Demonstrates Efficiency Gains

The BMW iX3, the first production model based on BMW Neue Klasse, showcases tangible engineering improvements enabled by the new architecture. Its wiring harness has been reduced by approximately 600 meters and is about 30% lighter compared to previous designs.
In addition, smart eFuses from Infineon Technologies AG replace many conventional fuses, introducing intelligent and software-controlled power distribution. This allows the BMW iX3 to deactivate unnecessary power consumption depending on driving or charging conditions.
As a result, energy efficiency improves by around 20%, demonstrating how BMW Neue Klasse combines software intelligence, advanced semiconductors, and optimized electrical systems to enhance overall vehicle performance and sustainability.
