BMW is set to unveil the iX3, its first production vehicle built on the all-new “Neue Klasse” architecture, at the IAA Mobility show in Munich this September. As the Munich-based automaker accelerates its transition to next-generation electric mobility, the iX3 will introduce a range of significant technological advancements, including ultra-fast 800-volt charging, bidirectional energy management, AI-powered driving systems, and cloud-based software integration.
Near-production prototypes of the iX3 are currently undergoing final testing at BMW’s Miramas development center in southern France, as the company describes the model as being in the final phase of its development.
Series production is scheduled to commence later this year at BMW’s newly constructed Debrecen plant in Hungary, where pre-series manufacturing is already underway. The iX3, classified as a mid-size SUV, is expected to be the vanguard of BMW’s new electric lineup, which will eventually extend Neue Klasse architecture benefits across all powertrain types.
Among the key highlights revealed ahead of the September debut is the iX3’s capability to charge at a peak rate of 400 kW, enabled by its 800-volt electrical system. During testing with Alpitronic’s HYC400 hypercharger, BMW demonstrated that the vehicle can recover more than 350 kilometers of range in just ten minutes.
While the company has not disclosed full battery specifications or a complete charging curve, it anticipates a 10-to-80 percent charging time of under 20 minutes. “Charging at 400V DC charging stations will, of course, still be possible,” the company added, in a clear contrast to rivals such as Mercedes-Benz, whose MMA-based CLA currently supports only 800V DC fast charging.
The BMW iX3 will offer a WLTP range of up to 800 kilometers, with even higher estimates in other regions—900 kilometers in China under the CLTC cycle and 400 miles in the United States per EPA standards. According to BMW, users will also be able to monitor and control the vehicle’s charging performance and energy flow remotely through the updated ‘My BMW’ app.
The iX3 will be among the first BMW models to feature bidirectional charging as a standard capability. This includes Vehicle-to-Load (V2L) functionality allowing up to 3.7 kW output in Europe for powering external devices. BMW is also preparing for Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) services, which will enable owners to feed energy back into their homes or the power grid.
To support these capabilities, BMW will offer a DC wallbox, which allows up to 19.2 kW of bi-directional power exchange, though pricing and market availability have not yet been disclosed. The brand says this bidirectional capability is part of its ambition to set “new standards for the integration of the vehicle into the energy market.”
Alongside energy innovations, the iX3 introduces a comprehensive overhaul of BMW’s software and electronics architecture, featuring four central high-performance computers. The flagship among them, called the “Heart of Joy,” governs propulsion, braking, energy recuperation, and aspects of steering. This system processes input data ten times faster than previous models, providing more responsive and precise driving dynamics. According to BMW, the system’s improvements allow the iX3 to manage turns with greater consistency and to decelerate to a stop using only regenerative braking in 98% of real-world situations.
These computing advancements support what BMW describes as the next-generation “Superbrain of Automated Driving,” a rule-based and AI-enhanced driver assistance system capable of processing information up to 20 times faster than its predecessor. The system is designed to respond to complex traffic scenarios in real time and will receive regular over-the-air updates via BMW’s expanded cloud platform.
Additional features include an AI-powered charging flap, which opens automatically when the vehicle approaches a familiar charging point, indicating an intention to recharge. Though presented as a convenience feature, BMW frames this capability as part of its broader effort to create a more intuitive and seamless ownership experience.
“Longer range, faster charging, an all-new display and operating concept, and the intelligence of four superbrains are the distinguishing features of the Neue Klasse,” said Mike Reichelt, Head of New Class at the BMW Group. “With the all-new BMW iX3, we bring our revolutionary technologies into series production for the first time, and we can hardly wait to see it in action on the road. All future BMW models, regardless of powertrain type, will benefit from the innovations and technology clusters of the Neue Klasse.”
The iX3’s global debut will take place at the IAA Mobility 2025 in September, with more technical details and pricing expected at that time. BMW’s rollout of the Neue Klasse platform marks one of the most comprehensive product and technology transformations in its history as the automaker seeks to lead the premium EV market with a new generation of intelligent and sustainable vehicles.
