Mercedes GLC Electric: An All-New EV Contender

The Mercedes GLC electric SUV enters a competitive market dominated by the BMW iX3 and the upcoming Volvo EX90. With a fully electric architecture designed to rival these segment leaders, the GLC offers modern tech, a sophisticated design, and strong performance credentials. During our extensive test drive in Portugal, we evaluated its real-world range, charging capabilities, interior features, and road manners over a 150-mile trip.

Key Specifications and Range

The electric Mercedes GLC is initially available as the GLC 400, featuring 483 horsepower and a four-wheel-drive setup powered by a 94.12 kWh battery. Mercedes claims a maximum range of 400 miles depending on trim, with lighter rear-wheel-drive variants expected to offer around 430 miles in the future. However, this range trails rivals like BMW's iX3 (500 miles) and the Volvo EX90 (503 miles). The reason is clear: both competitors use larger batteries exceeding 100 kWh.

In real-world conditions, the GLC electric averaged 3 miles per kilowatt-hour during mixed driving, slightly ahead of the BMW iX3 in recent What Car test comparisons. However, Tesla’s Model Y remains more efficient at 3.4 miles per kilowatt-hour in similar conditions.

Charging Performance

Charging infrastructure and speed are critical factors for EV buyers. Mercedes equips the GLC with cutting-edge fast-charging capabilities, supporting peak rates of up to 330 kW when connected to compatible chargers. This allows the vehicle to recharge from 10% to 80% in as little as 22 minutes.

During our test, charging from 28% to 80% took approximately 18 minutes on a 300 kW charger, with an average charging rate of 185 kW. This performance is competitive but slightly behind rivals like the BMW iX3’s theoretical capabilities. Still, drivers can expect to add 186 miles of range in just 10 minutes, minimizing downtime during long trips.

Interior and Practicality

Mercedes has redefined the interior of the GLC, incorporating a colossal 39.1-inch Hyperscreen spanning the dashboard. This setup comprises three displays: a driver instrument cluster, a center touchscreen, and a screen for the passenger, all integrated beneath a single glass panel. Standard on AMG Line Premium trims and above, this technology provides robust performance thanks to liquid cooling and responsive AI-enhanced voice controls.

Interior Measurements: Practical Space

Space is generous for passengers and cargo alike. Rear-seat legroom and headroom are ample, even beneath the panoramic roof. The fixed rear seats may disappoint those seeking adjustability, available in alternatives like the Tesla Model Y or BMW iX3.

Cargo volume matches the iX3, with a boot capacity of 520 liters. The rear seats fold flat in a 40:20:40 configuration, and air-suspension models can lower the rear axle for easier loading. There's also a front boot suitable for storage of a charging cable or carry-on suitcase.

Driving Comfort and Performance

The GLC electric feels at home on highways, thanks to its refined ride quality and optional air suspension. Mercedes includes rear-wheel steering in models with the £2,500 refinement package, improving stability at high speeds and maneuverability in tight spots with a turning circle of 11.2m. At 75 mph during our test, there was minimal wind noise, and despite noticeable tire noise, the ride remained comfortable on Portugal’s uneven roads.

On more demanding country roads, the GLC's clever adaptive suspension system, "Intelligent Damping," adjusted well to challenges, logging road irregularities for future use via cloud storage. In Sport mode, the car felt more grounded, with minimal body roll and accurate, well-weighted steering. Though not as sharp as the BMW iX3 in cornering dynamics, the GLC comes close.

Regenerative Braking and Driving Modes

Mercedes offers customizable regenerative braking settings, including a "one-pedal mode" via the strongest setting ("D-"). While effective, this might be overly aggressive for some drivers’ taste. However, standard braking systems also deliver efficient energy recuperation, ensuring minimal energy waste.

Pricing and Competitive Positioning

The Mercedes GLC starts at approximately £60,000 in the UK, placing it slightly above the BMW iX3 but in line with Volvo’s EX90. However, it’s important to factor in equipment levels. The GLC delivers innovative technology—including the expansive Hyperscreen, Intelligent Damping, and powerful voice assistant—making it a compelling option for those willing to pay for premium features.

Practical Considerations

• Best for Long-Distance Comfort: The GLC excels on highways with its quiet cabin and premium features like heated, supportive seats and adaptive suspension.
• Charging Infrastructure Awareness: Despite fast-charging capabilities, real-world charging reliability is subject to external factors like station capacity.
• Technology Strengths: The Hyperscreen display and connected services such as Intelligent Damping add tech appeal, but the lack of physical HVAC controls detracts from usability.

Final Thoughts

The Mercedes GLC electric combines luxury, comfort, and cutting-edge technology in a sleek SUV package. While it doesn’t outclass the BMW iX3 on range or handling and leans on par with the Volvo EX90 regarding price, its tech-integrated driving experience and premium interior make it a formidable option for EV buyers. A solid real-world efficiency of 3 miles per kWh rounds out a refined, enjoyable ride.
