As their competitors gain ground, BMW and Mercedes must impress with high-performing and innovative electric SUVs.
At the IAA in Munich, both brands showcased their latest offerings: the BMW iX3 50 xDrive and the Mercedes GLC 400 4Matic EQ, two compact SUVs ready to face off directly.
Under the hood, the Mercedes GLC 400 EQ produces 356 kW and 809 Nm of torque, slightly above the 350 kW and 644 Nm of the BMW iX3. This difference is noticeable in the 0 to 100 km/h time: 4.3 seconds for the GLC versus 4.9 seconds for the iX3. However, power is not the only criterion. In terms of range, the BMW iX3 stands out with 678 to 805 km WLTP depending on the configuration, compared to 713 km for the GLC. On the other hand, energy efficiency is in favor of Mercedes, with 2.93 km/kWh against 2.41 to 2.86 km/kWh for the BMW.
Charging and Ranges Highlighted
Both SUVs come equipped with NMC batteries and benefit from fast charging thanks to their 800-volt architecture. The iX3 can reach a peak of 400 kW, allowing a charge from 10 to 80% in just 21 minutes, while the GLC tops out at 330 kW for a recharge time of 24 minutes.
In terms of technology, BMW and Mercedes are multiplying panoramic screens, virtual assistants, and driving assistance systems. Mercedes goes further with its “multi-agent” system integrating ChatGPT and Bing AI, offering a more interactive experience for the driver and passengers.
Regarding pricing, the BMW iX3 50 xDrive is already offered in France starting at 71,950 euros. The Mercedes GLC 400 EQ will arrive later this year, at a price point that is expected to be very close to that of its Bavarian rival.
