The BMW iX3 opens the Neue Klasse era as the brand’s first software-defined vehicle, and it’s the featured car that sets the tone for what comes next. Speaking at the iX3’s US premiere, BMW’s R&D head Dr. Joachim Post explained how the project moves beyond scattershot ECUs to four central “Superbrains”, with a dynamic controller—aptly dubbed the Heart of Joy—coordinating powertrain, chassis and braking so the car behaves like one tightly integrated system.
Post’s brief is simple: define the electronic and software architecture first, then build the car around it. In the iX3, that means zonal hardware, clean separation of software from silicon, and compute headroom for rapid updates. The benefits land where drivers feel them: regeneration handles the vast majority of braking right down to a smooth standstill, while faster processing sharpens stability control and torque management, letting the iX3 carry speed with calm precision.
Inside, the iX3 debuts Panoramic iDrive, a pillar-to-pillar display that puts key data in your eyeline and pares back distraction. Steering-wheel controls handle core functions, and the interface is designed to absorb future AI features without ripping up the stack. As Post notes, the same backbone can host different regional partners for driver assistance while keeping the BMW character consistent.
Crucially, Post says the Neue Klasse logic isn’t confined to EVs. The four-computer layout, Panoramic iDrive and software approach will roll across dozens of BMW models, regardless of powertrain. That makes the BMW iX3 both a showcase and a template—an EV that proves how smart electronics, efficient energy recovery and crisp interfaces can refresh the brand’s dynamic brief for the years ahead.
