BMW Introduces Four Superbrains To Enhance Digital Architecture In Neue Klasse Models
BMW has introduced a cutting-edge digital nervous system for its vehicles, marking a significant advancement in automotive technology. This new system, set to debut in the Neue Klasse models, features four high-performance computers known as "Superbrains." These Superbrains enhance key functions like infotainment, automated driving, and vehicle access. They offer over 20 times the computing power of previous models and are designed to support future software updates.
The innovative electronic architecture is a cornerstone of BMW's strategy for the next generation of vehicles. This architecture simplifies the wiring harness by using a zonal approach, reducing wiring by 600 meters and saving 30% in weight. The vehicle's wiring is divided into four zones: front end, center, rear, and roof. High-speed data connections link the Superbrains to smaller control units called zonal controllers.
BMW's advanced software architecture builds on this new electronic framework. It allows continuous development of digital functions on stable platforms rather than starting anew with each vehicle generation. The software platforms operate on the Superbrains within the vehicle, with a "Shared Service Layer" acting as middleware. This layer provides cybersecurity and enables over-the-air updates.
The introduction of Smart eFuses plays a crucial role in enhancing energy efficiency by 20%. These digital fuses replace up to 150 traditional ones and allow intelligent programming for energy distribution. They enable selective activation of components, creating intelligent power modes for different vehicle states like driving or parking.
BMW has established a robust foundation for future-proof vehicle software development. The company employs around 10,000 IT and software experts worldwide. A tailored tool-chain called "CodeCraft" supports developers with generative AI tools, running in the cloud on up to 75,000 virtual CPUs.
"With the introduction of the Neue Klasse, we are entering a mode of software development where we achieve software continuity," says Christoph Grote, Senior Vice President BMW Group Electronics and Software. "Based on our advanced software architecture and the fact that today our global development teams generate 130 times more software than ten years ago, we see ourselves in an excellent competitive position."
Strategic Approach to Software
BWM follows a strategic "Make-or-Buy" approach for its software development. Brand-defining software like infotainment systems is developed internally while basic functionalities are sourced externally or through open-source solutions. This strategy ensures that BMW remains competitive while focusing on core innovations.
The first fully electric derivative of the Neue Klasse will enter production later this year at BMW's Debrecen plant in Hungary. The new electronic architecture will benefit upcoming BMW models from this launch onward.
BMW Group's U.S. Presence
In the United States, BMW maintains a strong presence with nearly 30 locations across 12 states. The Spartanburg plant in South Carolina is BMW's largest production facility globally and specializes in assembling Sports Activity Vehicles like the X3 and X5.
The company's activities support over 120,000 jobs nationwide and contribute more than $43 billion annually to the U.S. economy. BMW's sales network includes numerous retailers for its various brands such as MINI and Rolls-Royce.
"Technology openness is key to BMW's success," says Frank Weber, Board Member for Development at BMW AG. "Starting with the first model of the Neue Klasse, we will roll out these technologies across all segments and drivetrains."
This comprehensive approach ensures that future BMW models remain digitally advanced through over-the-air upgrades while benefiting from innovations developed for subsequent generations.
