The Mercedes GLC EQ takes the top spot among the new-generation electric SUVs from Mercedes, Audi and BMW. The Audi Q6 e-tron and BMW iX3 also bring advanced technology, strong performance and the comfort expected from Germany’s automotive elite.
The Audi Q6 e-tron, the oldest of the trio, arrived in 2024 and quickly set a high bar for refinement. The BMW iX3 now rides on the Neue Klasse platform, while the Mercedes GLC EQ uses the all-new MB.EA-M architecture. Mercedes-Benz describes MB.EA as “a able to grow system for midsize and large electric passenger cars”; technical reporting by Heise identifies the electric GLC as the first model associated with the dedicated platform. That puts the GLC within a modular architecture designed for more than one vehicle, rather than a single-model engineering solution. All three offer spacious interiors, but take different approaches to comfort and design. The Mercedes stands out for its plush rear seats and AGR-certified front seats, which provide excellent support. Audi’s seats rank among the segment’s best, with firm padding and impressive lateral support. BMW’s optional M Sport seats are more divisive: they offer strong side support but are less comfortable on long journeys because of their firmer, narrower design.
Rear passengers in the BMW iX3 get the group’s only adjustable backrest, making it a relaxed place to travel. The seat cushion is less padded, though, which becomes noticeable on longer trips. Each brand has taken a distinct approach to cockpit technology. BMW introduces Panoramic Vision, a slim head-up display that stretches across the lower windshield and can show everything from trip data to battery temperature. Most controls sit on a 17.9-inch central touchscreen. It is quick and bright, with a responsive voice assistant and a broad range of features.
Mercedes counters with its optional Hyperscreen, a 39.1-inch panel that combines the instrument cluster, central touchscreen and a dedicated passenger display. The system is fast, colorful and intuitive, and its voice assistant responds promptly. Audi’s interior is more understated, with an 11.9-inch driver display, a 14.5-inch central touchscreen and a 10.9-inch passenger monitor. The graphics are more restrained, but the system is well organized and responsive. Its voice control, but, trails BMW and Mercedes in speed and fluidity. BMW’s Neue Klasse technology package also pairs its digital interface with an 800-volt electrical system, making the iX3’s platform change impressive beyond the cockpit.
Performance and Driving Dynamics
All three SUVs use an 800-volt architecture with dual electric motors, delivering instant acceleration and smooth power. The Audi Q6 e-tron produces 462 hp, accelerates from 0 to 100 km/h in 4.8 seconds and has a top speed limited to 210 km/h. Its regenerative braking can be adjusted with steering wheel paddles, and the one-pedal driving mode works particularly well. The Q6 feels agile for its 2.46-ton weight, with pleasant steering and, when equipped with optional air suspension, a ride that balances comfort and control. It doesn’t absorb bumps as softly as the Mercedes, but is more forgiving than the BMW.
Braking performance is another point of difference. The Audi stops from 100 km/h in 33.4 meters, just ahead of the BMW’s 33.9 meters. Both trail the Mercedes, which manages the same stop in 31.6 meters. The BMW iX3 matches the Audi’s 4.8-second sprint to 100 km/h, with slightly higher output at 469 hp. At 2.34 tons, it is the lightest of the three and the most agile in corners, helped by precise, quick steering. Its steel suspension delivers a firmer, sportier ride, though, and can feel harsh over rough surfaces, leaving it behind the others for comfort.
Range and Efficiency
The Mercedes GLC EQ leads in outright power, with 489 hp and a distinctive two-speed gearbox that helps it reach 100 km/h in 4.2 seconds, the fastest time here. Its regenerative braking is adjustable via paddles, and the one-pedal driving mode is intuitive and effective. The test car had air suspension and rear-axle steering, making it the most comfortable and surprisingly maneuverable of the group despite weighing 2.56 tons.
Battery capacity and range matter in electric SUVs. The GLC’s 94 kWh battery delivered 479 km in real-world testing. The BMW iX3, with its larger 108.7 kWh battery, managed 535 km, while the Audi Q6 e-tron covered 460 km from its 94.9 kWh pack. Energy consumption was close for the BMW at 21.9 kWh/100 km and the Mercedes at 21.7 kWh/100 km. The Audi was slightly higher, at 23.5 kWh/100 km. These road-test distances differ from WLTP figures: EV Compared reports a BMW iX3 50 xDrive WLTP range of approximately 679 to 805 km, depending on configuration. BMW also says the vehicle can add up to 372 km of WLTP-rated range in 10 minutes. That is a standardized-cycle estimate, not a promise of the same distance in every driving condition.
Peak DC charging figures offer another comparison: the Mercedes is reported at up to 330 kW, the BMW iX3 at up to 400 kW and the Audi at up to 270 kW. Auto.cz’s comparison lists the Audi SQ6 e-tron, not the standard Q6 e-tron, at 270 kW and 21 minutes for a 10% to 80% charge. It gives the BMW iX3 50 xDrive the same 21-minute charging window. Peak power alone does not determine how long a stop takes. Battery temperature, starting state of charge and the charging curve all affect how much energy a vehicle takes on. In practical terms, the BMW has the highest stated peak rate. The Mercedes and Audi figures need to be considered alongside their respective battery sizes and charging behavior.
Final Verdict
After extensive evaluation, the Mercedes GLC EQ emerges as the clear winner, with the strongest overall combination of comfort, technology and performance. The BMW iX3 impresses with its range and advanced electronics. The Audi Q6 e-tron remains a refined and enjoyable option, albeit at a higher price point. Broader trends in electric mobility are also visible in the evolution of charging infrastructure. London’s new lamp post charging, for example, offers a glimpse of how cities are adapting to the EV transition, as explored in this recent analysis of urban charging solutions.
The final ranking puts the Audi Q6 e-tron in third place (score: 8.5), the BMW iX3 in second (8.7) and the Mercedes GLC EQ at the top with a score of 8.9. Each model raises expectations for premium electric SUVs, but Mercedes currently leads the pack.
All three models reflect a broader shift in the European car market toward electrification and digitalization. Their rapid development and increasingly competitive features show how quickly the premium EV segment is developing, with German brands setting the pace for the rest of the industry.
