Silicon Carbide Revolution: The i4's Efficiency Breakthrough
BMW's implementation of silicon carbide (SiC) semiconductor components represents a watershed moment in electric vehicle technology. This advanced material, combining silicon and carbon atoms, delivers superior thermal performance and higher voltage operation capabilities that traditional silicon simply cannot match.
Unlike conventional silicon-based components, SiC semiconductors operate at higher switching frequencies with dramatically reduced losses. They also provide approximately three times the thermal conductivity of silicon, enabling faster heat dissipation and more efficient power conversion throughout the drivetrain.
Meet the Enhanced i4 Family
Innovation Focus: Entry-level efficiency with cutting-edge SiC technology integration.
Innovation Focus: Optimal balance of performance and efficiency with extended range capability.
Innovation Focus: Ultimate performance flagship with 57 additional horsepower over predecessor.
Digital Key Plus: Redefining Vehicle Access
BMW's redesigned Digital Key system transforms how drivers interact with their vehicles. The new setup process eliminates complexity while adding unprecedented sharing capabilities and security features.
Simply tap the Setup Card to your smartphone or scan the QR code for instant Digital Key activation. No complex pairing procedures required.
Deactivated backup card provides secure physical key functionality for service appointments, valet parking, or emergency situations.
Share digital keys with up to 18 devices via simple text message, with individual permissions and restrictions for each user.
Set speed limits, acceleration restrictions, and other parameters for teen drivers or other authorized users.
The new BMW Digital Key represents the future of automotive access—secure, convenient, and incredibly flexible. Being able to share vehicle access with family members while maintaining complete control over permissions is a game-changer for modern mobility.
Beyond the Drivetrain: Comprehensive Upgrades
Enhanced Standard Equipment
Tire Repair Kit Plus becomes standard across multiple model lines including the 1 Series, 2 Series Coupé, and 3 Series, providing drivers with emergency mobility solutions.
Extended Battery Warranty now covers all electric BMW models with an 8-year/160,000-kilometer guarantee against capacity loss below 70%, effective from April 1, 2025.
Advanced Digital Services
BMW Intelligent Personal Assistant gains alternative voice options and expanded language support, plus Amazon Alexa integration in select models.
BMW Maps receives UI enhancements with faster access to frequently used functions and improved destination input.
Parking Assistant Plus now utilizes surrounding signage to identify available spots and ensure precise parking maneuvers.
BMW Individual special paints are now directly accessible in the BMW Configurator, simplifying the customization process.
Market Impact and Future Implications
These updates position BMW at the forefront of electric vehicle innovation. The silicon carbide implementation follows similar efficiency improvements across BMW's EV lineup, including the recently updated iX crossover which achieved a 10% efficiency boost.
