The New BMW iX3 vs. Mercedes-Benz Electric GLC

The electric midsize SUV segment is heating up, with German luxury giants BMW and Mercedes-Benz launching their latest contenders: the all-new BMW iX3 and the all-electric Mercedes-Benz GLC. Both promise cutting-edge technology, impressive performance, and unmistakable brand identity. Let’s break down how they compare.

Exterior Design & Dimensions

BMW iX3

The iX3 masterfully blends retro and futuristic elements. It retains the iconic BMW “Double Kidney Grille,” now inspired by classic vertical designs and surrounded by an illuminated outline. The futuristic headlights evoke the “Angel Wing” design language. It avoids the ubiquitous full-width taillight trend, opting instead for elongated, intricate LED units. With an M Sport package and standard 22-inch wheels, it presents a powerful, sporty stance.

• Dimensions: 4780 mm L / 1895 mm W / 1635 mm H / 2895 mm Wheelbase

Mercedes-Benz GLC

The electric GLC features a redesigned, closed-off grille that can be optioned with a lighting effect featuring 942 individual pixels, paired with digital headlights and star-pattern tail lights for a high-tech, recognizable appearance.

• Dimensions: 4845 mm L / Wheelbase (+84 mm vs. fuel version)

Verdict: The iX3 is sporty and evolutionary, while the GLC is bolder and more futuristic in its lighting signature.

Interior & Technology

• Tech: Runs on Mercedes’ own MB.OS platform with a new AI voice assistant that supports natural conversation, integrates both Microsoft and Google AI, and supports over 40 entertainment apps.
