The Mercedes-Benz EQC 400 4MATIC holds a unique position in the history of electrification. As the first dedicated series-production electric vehicle under the Mercedes-EQ sub-brand, it represented a bridge between the traditional luxury world of the internal combustion engine (ICE) and the silent, torque-rich future of battery electric vehicles (BEVs). Although Mercedes-Benz officially ended production of the EQC in the second quarter of 2023 to make way for the next generation of EVA2-platform vehicles like the EQE and EQS SUVs, the EQC 400 remains a highly relevant model in the pre-owned luxury market.

Defining the EQC 400 4MATIC

The EQC 400 is a midsize luxury SUV that shares much of its DNA with the popular Mercedes-Benz GLC. Unlike the later EQ models that feature the "One-Bow" design language, the EQC retains a more classic SUV silhouette. It is powered by two asynchronous electric motors—one on the front axle and one on the rear—providing a combined output of 300 kW (402 horsepower) and a substantial 760 Nm (561 lb-ft) of torque.

This vehicle was never meant to be a disruptive tech-on-wheels experiment; instead, it was engineered to be a Mercedes-Benz that happens to be electric. This distinction is crucial for understanding its driving dynamics and interior philosophy.

Performance and Driving Dynamics

Driving the EQC 400 4MATIC reveals a focus on "serene speed" rather than the aggressive, jerky acceleration often found in performance EVs. While it can sprint from 0 to 100 km/h (0-62 mph) in just 5.1 seconds, the way it delivers that power is remarkably linear.

Dual-Motor All-Wheel Drive System

The 4MATIC system in the EQC is fully variable. In most daily driving scenarios, the front motor is optimized for maximum efficiency in the low-to-medium load range. When the driver demands more power or when traction becomes an issue, the rear motor kicks in to provide sporty handling and stability.

In our testing, the transition between these motors is imperceptible. There is no "hunting" for traction; the torque vectoring is handled electronically in milliseconds. However, the EQC is a heavy vehicle, weighing approximately 2,495 kg (5,500 lbs). You feel this mass during hard cornering, where the laws of physics eventually catch up with the suspension. Mercedes mitigated this by mounting the 650 kg battery pack low in the floor, providing a center of gravity much lower than a standard GLC.

Refinement and NVH Levels

One area where the EQC 400 remains an industry leader is Noise, Vibration, and Harshness (NVH) control. Mercedes engineers went to extreme lengths to isolate the electric drivetrains from the cabin. The motors are supported by rubber mounts at two points, and the entire subframe is isolated from the body. Combined with standard dual-pane acoustic glass, the EQC is arguably one of the quietest electric SUVs ever made. At highway speeds of 110 km/h, the cabin remains a sanctuary, with wind and tire noise kept to a distant hum.

Battery Technology and Charging Realities

The EQC 400 is equipped with an 80 kWh usable capacity lithium-ion battery (roughly 86 kWh gross). In the current landscape of 100+ kWh batteries, this might seem modest, but for the era of its release, it was competitive.

Range Expectations

The official WLTP range is rated between 400 km and 450 km (248–280 miles). However, real-world range is a different story. For drivers primarily using the vehicle on highways at high speeds, the range typically settles between 320 km and 350 km (200–218 miles). In urban environments where regenerative braking can be maximized, achieving 400 km is possible.

Charging Speeds

The EQC supports DC fast charging at up to 110 kW. While modern 800V architectures like the Porsche Taycan or Hyundai Ioniq 5 can hit 230-350 kW, the EQC's charging curve is relatively stable.

  • 10% to 80% Charge: Approximately 40 minutes at a 110 kW station.
  • AC Home Charging: The onboard charger supports 11 kW (on later models), which allows for a full overnight charge in about 7.5 to 8 hours using a standard Level 2 wallbox.

It is worth noting that earlier EQC models (pre-2021) featured a 7.4 kW onboard charger, which significantly slowed down home charging times. Prospective used buyers should check the specific model year to confirm the charging capacity.

Luxury Interior and MBUX Integration

The interior of the EQC 400 is a masterclass in blending traditional luxury with "electric" accents. You won't find the minimalist, screen-only approach of a Tesla here. Instead, there is a tactile mix of leather, open-pore wood, and high-quality plastics.

The "Electric" Aesthetics

Unique to the EQC are the rose-gold metallic accents on the air vents and a ribbed dashboard design that mimics the cooling fins of high-end audio amplifiers. The ambient lighting system offers 64 colors and can even be synced with the charging status, pulsing blue when the car is plugged in.

MBUX Infotainment

The EQC features the twin 10.25-inch display setup running the Mercedes-Benz User Experience (MBUX) system. While newer models have the "Hyperscreen," this older version is often praised for having a better balance of physical buttons and touch controls.

  • Navigation with Electric Intelligence: This is a standout feature. The system calculates the fastest route including necessary charging stops, taking into account the current battery level, weather, and traffic.
  • "Hey Mercedes": The voice control is highly functional, allowing you to change the temperature or find a charging station without taking your eyes off the road.

Practicality and Dimensions

Because the EQC shares its platform with the ICE-powered GLC, there are some compromises in packaging.

The Missing "Frunk"

One of the most common complaints about the EQC 400 is the lack of a front trunk (frunk). When you open the hood, you see a massive structural brace and plastic shrouding covering the front motor and power electronics. This is a direct result of the modified GLC platform.

Cargo and Seating

  • Boot Space: 500 liters with the seats up, expanding to 1,460 liters with the 40/20/40 split rear seats folded. This is slightly less than the GLC due to the battery floor, but the space is square and very usable.
  • Passenger Comfort: Front seat occupants enjoy typical Mercedes comfort with extensive adjustment and heating. Rear seat passengers, however, will notice a slight "knees-up" seating position due to the raised floor containing the batteries. There is also a transmission tunnel hump in the rear floor—a vestige of the GLC chassis—which makes the middle seat less comfortable for adults.
  • Towing: One of the EQC's strengths is its towing capacity of 1,800 kg (braked), which is superior to many other midsize electric SUVs in its class.

Regenerative Braking and Energy Management

The EQC offers one of the most sophisticated regenerative braking systems available. Using the steering wheel paddles, the driver can toggle between four main modes:

  1. D Auto: The car uses radar and navigation data to decide how much to slow down. If there is a car ahead or a roundabout coming up, it increases recuperation. On an empty road, it coasts.
  2. D+ (Coasting): The car glides with almost no resistance, ideal for highway efficiency.
  3. D (Standard): Mild recuperation, feeling like engine braking in a petrol car.
  4. D- (Strong): High recuperation.
  5. D-- (Maximum): This allows for "one-pedal driving," where the car can come to a complete stop just by lifting off the accelerator.

Is the EQC 400 a Good Used Buy in 2024 and 2025?

As the EQC moves into the used market, it presents a compelling value proposition for those who want a premium badge and top-tier build quality without the price tag of a brand-new EQE.

Pros of Buying a Used EQC 400:

  • Build Quality: Unlike some early EVs from new startups, the EQC feels "built like a tank." The fit and finish are exceptional.
  • Comfort: The suspension tuning (Steel springs front, air suspension rear) provides a ride quality that many modern EVs with 22-inch wheels can't match.
  • Depreciation: Much of the steep initial depreciation has already occurred, making it a bargain compared to its original MSRP.

Cons to Consider:

  • Efficiency: The EQC is not the most efficient EV. You can expect an average energy consumption of around 22–24 kWh/100km.
  • Charging Speed: 110 kW is becoming "slow" as 150 kW and 350 kW chargers become more common.
  • Tech Longevity: While MBUX is great, it won't receive the same level of over-the-air (OTA) updates as the newer "MB.OS" based vehicles.

Summary

The Mercedes-Benz EQC 400 4MATIC was a cautious but highly refined first step into the electric era for the Silver Arrow. It successfully translated the core values of the brand—comfort, silence, and luxury—into a zero-emission package. While it has been technically surpassed by the EQE SUV in terms of range and software, the EQC remains a formidable luxury SUV. It is best suited for the driver who prioritizes cabin quietness and material quality over sheer battery range or futuristic screen real estate.
