When Mercedes-Benz and BMW launch all-electric iterations of two of their best-selling mid-size SUVs within days of each other, the result is not merely market competition — it is a study in two divergent philosophies of premium mobility. The Mercedes-Benz GLC-EV (badged as the GLC with EQ technology) and the BMW iX3 occupy the same segment, the same price band and, to a degree, the same customer consideration set. Yet they answer different questions: What does a modern German luxury SUV look and feel like? and What should it prioritize — range and practicality, or presence and driving character?
Below is a compact, technical and judgment-based comparison that organizes the most relevant facts and offers a clear verdict for buyers whose priorities are engineering-led, rather than marketing-led.

| Towing Capacity (braked) | 2,400 kg (per some sources) | 2,000 kg (typical spec, depending on market) |
Key Interpretation
- Size & Interior / Cargo — GLC EV leads: In absolute dimensions (length, width, height, wheelbase), the GLC EV is larger than iX3, which translates into a slightly more spacious cabin and a larger rear boot and front “frunk.” For buyers prioritizing cargo flexibility, family hauling, or larger luggage capacity, GLC EV presents a tangible advantage.
- Battery & Range — iX3 leads: The iX3 packs a significantly larger battery (108.7 kWh vs 94 kWh), which gives it a WLTP-rated range that is substantially longer (~805 km vs ~713 km). For buyers focused on long-distance driving and minimizing charging stops, iX3 holds a clear advantage.
- Performance & Driving Dynamics — GLC EV slightly sharper: GLC EV offers higher peak power and faster 0–100 km/h acceleration. For those who value strong throttle response, overtaking capability, or a more performance-oriented feel, GLC EV will likely deliver a slightly more engaging driving experience.
- Charging Speed & Architecture — iX3 has edge in charging headroom: While both use 800-volt architecture supporting high-power DC fast charging, iX3’s higher battery capacity and charging headroom (up to 400 kW) gives it a slight edge in practical long-distance usability and flexibility.
- Tow & Utility — GLC EV shows strength: GLC EV’s higher tow rating (when applicable) and larger cargo/frunk volume make it more appealing if you intend to tow or carry bulky loads.
Who Should Choose Which
- Choose the GLC EV if you prioritize space, cargo versatility, occasional towing, sharper performance and a more commanding “luxury SUV” presence. It is especially suitable for families or users needing storage flexibility, or those valuing a slightly sportier driving character.
- Choose the iX3 if your priority is maximum electric range, long-distance travel, minimal charging downtime, and a battery-efficient daily driver with simpler charging logic. It fits well for drivers commuting long distances or who frequently travel between cities.
