Mercedes-Benz EQB as a used car

Mercedes-Benz EQB as a Used Car

The Mercedes-Benz EQB is one of the more interesting used electric SUVs on the market because it combines something that many compact EVs struggle to provide: genuine family practicality. While the smaller EQA is aimed more at buyers who can manage with a compact cabin and modest luggage capacity, the EQB is based on the more spacious GLB concept and can accommodate up to seven occupants when equipped with the optional third row. Add a relatively large battery, all-wheel-drive versions, a premium interior and the quietness of an electric powertrain, and the EQB becomes a particularly versatile used-car proposition.

The model arrived in Europe in 2021 and has since been offered in several versions, including the front-wheel-drive EQB 250 and more powerful dual-motor EQB 300 4MATIC and EQB 350 4MATIC. Later, the EQB 250+ added a larger battery and longer official range. This variety means that used buyers have plenty of choice, but it also means that two cars carrying the EQB name can have noticeably different performance, range and equipment.

There is another reason the EQB deserves careful consideration as a used car: electric vehicles depreciate differently from conventional cars, and the used price can make a premium EV significantly more accessible than it was when new. However, buyers need to look beyond the purchase price. Battery health, charging performance, software, recall status, tyres, suspension and the condition of the 12-volt electrical system are all important when inspecting a second-hand EQB.

What is the Mercedes-Benz EQB?

The EQB is essentially the electric member of Mercedes-Benz’s compact GLB family. Its upright body gives it a much more practical shape than the sleeker EQA, while the battery is positioned low in the floor. This creates a relatively high seating position without sacrificing too much cabin space.

The EQB’s dimensions help explain its appeal. It is approximately 4.68 metres long, 1.83 metres wide and around 1.69 metres high, depending on specification. Its relatively boxy body maximizes interior space, and the second-row seats can be moved to balance passenger room against luggage capacity. The optional third row transforms the car into a seven-seater, although the rearmost seats are best regarded as occasional seats, particularly for children. Used-car testing has highlighted the EQB’s unusual combination of up to seven seats and substantial luggage capacity.

The electric drivetrain also changes the character of the vehicle. Instead of an internal-combustion engine and conventional gearbox, the EQB uses one or two electric motors with a single-speed reduction transmission. Acceleration is immediate, the cabin is quiet and there are no traditional gear changes. For urban driving and commuting, this makes the EQB exceptionally easy to operate.

Why consider an EQB as a used car?

A genuinely practical electric SUV

One of the strongest arguments for buying an EQB is practicality. Many compact electric SUVs have attractive styling but sacrifice luggage space or rear-seat room in the pursuit of aerodynamic efficiency. The EQB takes a different approach. Its relatively upright shape provides useful headroom, while the adjustable second row allows owners to prioritize either passenger space or cargo capacity.

In five-seat configuration, the EQB 250 offers around 495 litres of luggage capacity according to current used-car technical data, with up to 1,710 litres available when the rear seats are folded. The dual-motor versions have slightly less space in some configurations.

The optional third row is perhaps the feature that most clearly separates the EQB from many rivals. Seven seats make the car considerably more useful for families, although the two rear-most seats are not equivalent to the second row. They are best suited to children or shorter passengers, and luggage capacity becomes very limited when all seven seats are occupied.

A premium interior without the size of a large SUV

The EQB’s interior is familiar to anyone who has driven a contemporary Mercedes-Benz. Depending on specification, the dashboard features digital instruments, the MBUX infotainment system, voice control and smartphone connectivity. Higher-specification cars can also have features such as augmented-reality navigation, premium audio, panoramic glass roofs, electrically adjustable seats and extensive driver assistance.

The cabin is not as extravagant as the interior of larger Mercedes EQ models, but that can actually be an advantage on the used market. The EQB concentrates on usability rather than attempting to create a futuristic lounge. It feels like a conventional Mercedes SUV that happens to have an electric drivetrain.

Which EQB version should you choose?

EQB 250

The EQB 250 is the straightforward front-wheel-drive version. Early cars use a 66.5 kWh lithium-ion battery and a rear-mounted electric motor producing approximately 190 PS and 385 Nm. Mercedes quotes a 0–100 km/h time of 8.9 seconds and a maximum speed of 160 km/h.

For everyday driving, the EQB 250 has sufficient performance. The instant response of the electric motor means that it does not feel slow when pulling away from junctions, and the single-speed transmission provides smooth acceleration without conventional gear changes.

The front-wheel-drive layout also makes the EQB 250 an attractive option for buyers who do not need all-wheel drive. It is generally simpler than the dual-motor versions, and the absence of a second motor can help keep energy consumption lower.

EQB 250+

The EQB 250+ is particularly interesting for used buyers because it combines the single-motor front-wheel-drive layout with a larger battery. Later versions use approximately 70.5 kWh of usable battery capacity, with official WLTP range reaching around 500 km depending on specification. Used-car testing puts realistic everyday range considerably lower, at roughly 300–350 km under typical conditions.

For many owners, the 250+ makes more sense than choosing a more powerful version. The additional battery capacity is useful every day, while the 190 PS electric motor remains more than adequate for normal driving. If long-distance range is more important than acceleration, this version deserves close attention.

EQB 300 4MATIC

The EQB 300 4MATIC adds a second electric motor and all-wheel drive. Early versions produce approximately 228 PS and 390 Nm, with a 0–100 km/h time of around 8 seconds.

The major advantage is traction rather than outright performance. The two motors can distribute propulsion between the axles and provide additional confidence on slippery roads. This can be valuable in regions with regular winter conditions, particularly when the car is equipped with suitable winter tyres.

The downside is increased energy consumption and additional mechanical and electrical complexity. For an owner who spends most of the year driving on dry roads, the advantages of 4MATIC may not justify the additional energy requirements.

EQB 350 4MATIC

At the top of the original range sits the EQB 350 4MATIC, producing around 292 PS and 520 Nm. With a claimed 0–100 km/h time of approximately 6.2 seconds, it is considerably quicker than the EQB 250 and gives the family SUV surprisingly strong acceleration.

The 350 is the choice for buyers who want performance as well as practicality. It can make motorway overtaking effortless and feels considerably more energetic than the standard single-motor car. However, performance comes with increased electricity consumption, and the heavier dual-motor setup means that tyres and suspension components also deserve careful inspection.

What is the real-world range?

Range is one of the most important factors when buying a used electric car, but the official WLTP figure should never be treated as a guaranteed distance. Temperature, speed, wheel size, heating or air-conditioning use, wind, rain and driving style can all make a significant difference.

The original 66.5 kWh EQB models generally provide a practical range of around 300–350 km in ordinary use, according to recent used-car testing. The later 250+ with its larger battery can achieve a higher figure, with Mercedes offering an official WLTP range of up to around 506 km depending on configuration.

Motorway driving at high speed is particularly demanding because aerodynamic resistance increases rapidly as speed rises. A winter motorway journey can therefore produce a dramatically shorter range than a summer urban trip. Buyers should calculate their requirements based on the worst realistic conditions rather than the best advertised number.

For a commuter covering 50–100 km per day and charging at home, even an early EQB 250 can provide plenty of flexibility. For frequent 400–500 km journeys, the 250+ and access to reliable rapid-charging infrastructure become much more important.

Charging a used EQB

Home charging

Home charging is arguably the most important part of the EQB ownership experience. With an 11 kW AC wallbox and suitable electrical installation, the car can be charged overnight, making the daily routine much simpler than relying on public charging.

The exact charging equipment depends on the model year and market, so buyers should verify whether the individual car has the desired AC charging capability and whether the appropriate charging cables are included.

DC rapid charging

The EQB’s DC charging performance is one of the areas where the model has begun to show its age. Early cars have a maximum DC charging rate of around 100 kW. Mercedes has quoted approximately 30 minutes for a 10–80 percent charge under suitable conditions.

That is perfectly usable for occasional long-distance trips, but newer EVs increasingly offer substantially higher peak charging rates. Recent used-car assessments likewise describe the EQB’s approximately 100 kW DC charging as relatively modest by current standards.

For someone who mostly charges at home, this limitation is relatively unimportant. For a driver who regularly makes long motorway journeys, however, charging speed should be part of the purchasing decision.

What should you check before buying?

Check the high-voltage battery

The high-voltage battery should be the first major item on any used-EQB inspection. Ask the seller or Mercedes-Benz dealer for information about the battery’s condition and, where possible, obtain a battery-health report.

Mileage alone does not tell you whether an EV battery is healthy. Charging history, temperature exposure and the vehicle’s usage pattern all matter. A car that has covered 100,000 km is not automatically a poor purchase if its battery has retained a high percentage of its original capacity.

Recent testing has even identified an EQB battery with a state of health of 95.5 percent after more than 106,000 km and three and a half years, demonstrating that mileage does not automatically translate into severe battery degradation.

Check recall history carefully

Recall status is particularly important for the EQB. Several battery-related recalls have affected certain vehicles, including campaigns concerning the possibility of internal high-voltage battery faults.

In February 2026, a US recall covering certain 2023–2024 EQB 250+, 2022–2024 EQB 300 4MATIC and EQB 350 4MATIC vehicles addressed a potential internal high-voltage battery failure that could result in a vehicle fire. The stated remedy involves battery replacement, while earlier campaigns had involved battery-management software.

European owners should not assume that a US recall database automatically determines the status of their car, but the existence of these campaigns makes VIN-specific checking essential. ADAC’s German database has also listed battery-related campaigns affecting EQB vehicles, including a campaign involving a potential high-voltage battery short circuit.

Before purchasing, ask an authorized Mercedes-Benz dealer to confirm whether every recall and service campaign applicable to the exact VIN has been completed. If a vehicle is subject to an outstanding safety campaign, obtain written confirmation of the required remedy before proceeding.

Inspect the 12-volt battery and electronics

An electric car still has a conventional low-voltage electrical system, and the 12-volt battery can cause problems even though the main propulsion system is fully electric. Recent used-car assessments have reported that weak 12-volt batteries can contribute to system errors on the EQB.

The test drive should therefore include a complete examination of the dashboard for warning messages. Operate the infotainment system, cameras, parking sensors, electric tailgate, climate control, seats, windows and all available driver-assistance functions.

Software should also be checked. Some used-car reports have identified occasional infotainment, Bluetooth and over-the-air-update issues. These problems may not prevent the vehicle from driving, but they can be frustrating and potentially expensive if hardware is involved.

Suspension, tyres and brakes

The EQB is a relatively heavy vehicle because of its battery, and that weight places greater demands on suspension components and tyres. Used-car inspections have identified suspension links and bushes as areas worth examining, particularly on higher-mileage examples.

Listen for knocking or creaking noises when driving over broken surfaces and check whether the car tracks straight under braking. Uneven tyre wear can indicate alignment or suspension problems.

Tyres are particularly important because an electric SUV can produce substantial torque immediately. A set of quality tyres in the correct specification is not an area where buyers should try to save money. Check tread depth, sidewalls, age and wear across the entire contact patch.

The brakes should also be inspected. Regenerative braking means that the friction brakes may be used less frequently than on a conventional car, which can reduce pad wear but can also mean that discs may suffer from corrosion if they are rarely used aggressively enough to clean their surfaces.

How practical is the EQB?

Five-seat configuration

With five seats, the EQB is a genuinely practical family SUV. The second-row bench can be adjusted, allowing the owner to create more legroom or more luggage space as required. The square body shape makes loading relatively straightforward, and the high roof provides good headroom.

This is where the EQB has an important advantage over the sleeker EQA. It is not simply a larger electric SUV by exterior dimensions; its shape is designed around interior space.

Seven seats

The optional third row is one of the EQB’s defining features. Few compact premium electric SUVs offer seven seats, and that makes the EQB unusual on the used market. However, buyers should be realistic about what those seats can do.

The rearmost seats are most appropriate for children or shorter adults. When they are raised, luggage capacity becomes very limited, so a family using all seven seats will need to plan carefully. Nevertheless, having the option can be extremely useful for occasional journeys with extra passengers. Recent testing confirms that the EQB can be configured as a seven-seater, with the third row folding into the floor when not required.

Is the EQB expensive to maintain?

Electric powertrains eliminate many conventional maintenance items. There is no engine oil, spark plugs, conventional exhaust system or multi-speed automatic gearbox to service. Regenerative braking can also reduce brake wear.

However, this does not make the EQB a cheap car to maintain. It remains a premium Mercedes-Benz, and components such as tyres, suspension, climate-control systems, electronic modules and high-voltage components can be expensive. The 12-volt electrical system and software also deserve attention.

Insurance, tyres and electricity costs should therefore be included in the ownership calculation. A used EQB may be considerably cheaper to buy than a new one, but its premium-car running costs do not disappear simply because the vehicle has depreciated.

Is the Mercedes-Benz EQB a good used car?

The Mercedes-Benz EQB has a strong argument as a used electric family car because it offers something that many alternatives cannot: a relatively compact exterior combined with genuine five-seat practicality and optional seven-seat capacity. Its quiet electric drivetrain, comfortable ride and premium cabin make it particularly appealing as a daily family vehicle.

The choice of powertrain is important. The EQB 250 is adequate for most drivers and can be an efficient option for commuting, while the 250+ offers additional battery capacity and therefore greater flexibility on longer journeys. The EQB 300 and 350 4MATIC provide stronger performance and all-wheel drive, but their additional motors bring higher energy consumption and greater technical complexity.

The most important consideration when buying any used EQB is the individual vehicle’s condition. Battery health, charging operation, recall completion, software, 12-volt battery condition and suspension should all be examined before purchase. The recent high-voltage battery recalls make a VIN-specific recall check especially important.

For drivers who can charge at home and need a practical electric SUV, the EQB can make considerable sense as a used purchase. Its charging technology is no longer class-leading, but its combination of interior space, seven-seat availability, electric refinement and Mercedes-Benz comfort remains distinctive.

Mercedes-Benz EQB technical specifications

The following table summarises the principal specifications of the main EQB versions. Figures can vary according to model year, market, equipment and battery specification, so the exact VIN and factory specification should always be checked when evaluating a particular used vehicle.

*Specifications can vary by model year and market. Early EQB models use a 66.5 kWh battery, while the later EQB 250+ uses a larger battery of approximately 70.5 kWh. Technical data from recent used-car assessments lists 190 PS for the EQB 250, 228 PS for the EQB 300 4MATIC and 292 PS for the EQB 350 4MATIC.

The EQB’s technical concept remains relatively straightforward: a 400-volt electrical architecture, single-speed transmission and either one or two electric motors depending on version. The dual-motor EQB 300 and 350 use 4MATIC all-wheel drive, while the EQB 250 and 250+ are front-wheel drive.

For a used-car buyer, however, the numbers in the table are only part of the story. The most important specifications to verify on an individual vehicle are the exact battery capacity, charging equipment, drivetrain, seating configuration, factory options and current battery health. A carefully inspected EQB with a healthy battery and complete recall history can offer a particularly useful combination of electric driving, premium comfort and family practicality, making it one of the more distinctive used electric SUVs in its class.
