The 2027 Mercedes GLC EQ represents a significant step forward for Mercedes-Benz, delivering a fully electric option to their highly popular GLC lineup. As electric vehicles (EVs) play a growing role in the automotive market, Mercedes has refined its approach to design, engineering, and customer appeal. But how does the GLC EQ compare to its main competitor, the BMW iX3, and does it surpass its combustion-engine counterpart? Let’s break it down.

Exterior design and trims

Mercedes has retained the classic GLC aesthetic while modernizing it with EV-specific elements. The front grille, inspired by vintage models like the W108 and W109, presents a mix of retro charm and high-tech innovation. Illuminated accents, including the star logo, add a futuristic touch. However, regulations in markets like the EU limit some illumination options, making the U.S. versions slightly flashier.

The GLC EQ comes in multiple trims, including the Avantgarde and the AMG Line. The Avantgarde trim features chrome accents for a clean, elegant look, while the AMG Line sharpens the design with dark chrome detailing and the optional Night Package for a sportier appearance. Wheel options range from 19 to 21 inches, catering to both practical and aggressive styling preferences. Mercedes emphasizes personalization through a variety of color options, including the standout “Thomas Blue,” a bold and vibrant shade.

A noteworthy addition is the front trunk (frunk) feature, offering ample space for charging cables and small items. The long hood and classic SUV proportions align with the traditional GLC identity, reinforcing its status as a luxury offering.

Interior design and comfort

Inside, the GLC EQ merges high-end materials with cutting-edge style. Soft-touch surfaces, high-quality leatherette, and optional matte wood inlays make the cabin feel premium. The Avantgarde trim features a traditional steering wheel and clean design, while the AMG Line interior integrates sportier features like a two-spoke steering wheel.

Mercedes has also introduced advanced materials, moving away from animal-based leather in favor of high-grade synthetic alternatives. The Artico leatherette seats are soft and durable, offering enhanced comfort compared to traditional materials. Buyers can also opt for microfiber upholstery in sportier configurations. The inclusion of classic physical door handles, a safety consideration in markets like China, along with Keyless Go options, speaks to thoughtful customer feedback integration.

Compared to the BMW iX3, the leatherette quality in the GLC EQ is slightly firmer, though still highly enjoyable. Both the comfort seat and sport seat configurations cater to different tastes, with heating and cooling available to enhance user convenience.

Performance and driving dynamics

Powertrain and acceleration

The 2027 GLC EQ comes equipped with Mercedes' all-electric architecture, the MB.EA platform. A hallmark of this platform is a two-speed gearbox, which contributes to rapid acceleration and high-speed efficiency. The GLC EQ achieves 0-100 km/h in just 4.3 seconds, significantly outpacing the BMW iX3's 4.9-second performance.

The battery capacity of the GLC EQ is 94.5 kWh (net), delivering competitive range potential. However, the iX3’s 108.7 kWh battery offers slightly better range capability, aided by its optimal aerodynamics, including a Cd value of 0.24 compared to the GLC EQ’s 0.26.

Charging performance

When plugged into a DC fast charger, the GLC EQ supports up to 330 kW peak charging, capable of going from 10% to 80% battery charge in roughly 22 minutes. Real-world figures suggest that its top charging rate briefly exceeds 350 kW but tapers off quickly, unlike the BMW iX3, which maintains steadier charging curves. The iX3 may charge faster overall for larger battery capacities, providing an edge for long-distance drivers.

Suspension and handling

The GLC EQ sets itself apart with a focus on ride comfort and agility. Air suspension combined with rear-axle steering (up to 4.5 degrees) ensures smooth handling and tight cornering. While the iX3 lacks rear-wheel steering and air suspension, the GLC EQ’s dynamic abilities come at a higher price point.

Technology and features

The GLC EQ incorporates the latest Mercedes MBUX infotainment system with an expansive center screen, voice commands, and various driver-assistance technologies. Features such as adaptive cruise control, lane-keeping assistance, and advanced regenerative braking modes elevate the driving experience.

Practical takeaways

For buyers prioritizing luxury, comfort, and dynamic performance, the 2027 Mercedes GLC EQ is a standout option in the electric SUV market. Its use of advanced materials, focus on design continuity, and superior driving dynamics distinguish it from competitors like the BMW iX3. However, those needing maximum range may lean toward the iX3, as it offers slightly more battery capacity.

Regardless, Mercedes has succeeded in creating an EV that retains the essence of the GLC while adapting to the demands of electric performance and modern luxury. The inclusion of extensive customization options ensures buyers can tailor the vehicle to their exact preferences, whether that’s a classy Avantgarde finish or a bold AMG Line upgrade.

Conclusion

The 2027 Mercedes GLC EQ is more than just another electric SUV; it’s a testament to Mercedes-Benz's dedication to premium EV craftsmanship. While the BMW iX3 offers certain advantages in range and charging efficiency, the GLC EQ leads in design, luxury, and handling. Buyers will ultimately need to weigh their priorities, but as a complete package, the GLC EQ makes a strong case as one of the premier electric SUVs available today.
