Mercedes-Benz EQB: X243 generations, batteries and seven seats
Mercedes-Benz EQB — the electric sibling of the GLB and one of the few compact EVs that can seat seven. We look at EQB generations, batteries, real-world range, charging and what to check when buying a used EQB.
EQB in brief
The EQB was launched in 2021 and is based on the GLB. It has a tall, boxy body, so there's plenty of headroom inside, and the boot is larger than the smaller EQA. Daily tech, the interior and MBUX multimedia are almost identical to the GLB.
The EQB's standout feature is the option for a third row of seats. It's suitable for kids and short trips, and when not in use, it folds flat into the boot floor. Therefore, the EQB is often chosen by families needing a spacious but not overly large EV.
Early EQB and the refreshed model — what's the difference
Early EQB models come with a roughly 66.5 kWh usable battery. The main versions are the EQB 250 with front-wheel drive and the EQB 300 4MATIC and EQB 350 4MATIC with two motors and all-wheel drive.
The 2023 refreshed EQB gets a revised front end with a star-pattern grille, the latest MBUX software and a new steering wheel. Later models feature the EQB 250+ with a larger, roughly 70.5 kWh battery — this is the version with the longest range.
Most used cars on the market are from earlier generations. If your primary concern is range, look for the EQB 250+, but if you often drive on slippery or gravel roads, consider the all-wheel-drive versions.
Versions, battery, and charging
The EQB 250 and EQB 250+ deliver around 190 hp, the EQB 300 4MATIC around 228 hp, and the EQB 350 4MATIC around 292 hp. Since the EQB is taller and heavier than the EQA, it consumes a bit more energy, especially on the motorway.
According to the manufacturer's (WLTP) data, early EQB models cover around 400 km or a bit more, while the EQB 250+ manages roughly 500 km. In reality, you can usually expect around 300–380 km in the summer, and about a quarter less in the winter. A fully charged car and large wheels further reduce the range.
In Europe, the EQB is charged via a CCS2 connector: typically with alternating current up to 11 kW, and at fast-charging stations up to around 100 kW. Not all cars come with a heat pump, but it certainly helps save energy for heating the cabin in winter.
What to check when buying a used EQB
First and foremost, the battery condition. Request a Mercedes-Benz service battery health (SoH) check, which shows the remaining capacity in percentages. Mercedes electric vehicles usually come with an 8-year or 160,000 km manufacturer's warranty on the battery — check how much of it remains.
If the car has a third row, check that the seats fold and tumble easily, and that their mechanisms and seatbelts aren't damaged. Second-row seats often slide forward and back — test this mechanism too.
Test the charging with both alternating and direct current, check the multimedia system, cameras, and driver-assistance features. Ask if the manufacturer's updates and recall work have been done, inspect the tyres, and check the car's history using the VIN.

Comparison of EQB versions
| EQB 250 | EQB 250+ | EQB 300 4MATIC | EQB 350 4MATIC | |
|---|---|---|---|---|
| Who it's for | For the city and family | For long journeys | Ideal for winter and off-roading | For faster driving |
| Gearbox | Front wheels | Front wheels | All wheels | All wheels |
| Power | Around 190 hp | Around 190 hp | Around 228 hp | Around 292 HP |
| Mileage (relatively) | Average | Maximum | Average | Slightly less |
| Alloy wheels (usually) | 18 inch | 18–19 inch | 18–19 inch | 19–20 col. |
| Price in the used market (relatively) | € | €€ | €€ | €€€ |
Families who mostly drive in the city and its surroundings will find the EQB 250 sufficient. If you frequently travel further, opt for the EQB 250+, and all-wheel drive if it's truly necessary in winter.
Pros
- Optional third row of seats
- Spacious interior and large boot
- Quiet, comfortable ride
- Practical, boxy body
Cons
- Third row is cramped for adults
- Higher energy consumption on the motorway
- Fast charging is slower than for larger electric vehicles
Frequently asked questions
Is the EQB suitable for a family of seven?
Only partially. The third-row seats are for children or shorter adults and short trips. With all seven seats in use, the boot is very small, so the EQB is better suited to a family of five who occasionally need extra space.
How far does the EQB really go in winter?
Early EQB models in winter typically cover around 250–300 km, less on the motorway. The EQB 250+ with its larger battery goes further, and the heat pump helps reduce losses in the cold.
How does the EQB differ from the GLB?
The EQB is the electric version of the GLB: the body and interior are very similar, but instead of an internal combustion engine, it has an electric drivetrain and a battery under the floor. The EQB is quieter and cheaper to run if you charge at home, but the GLB is more comfortable for long journeys.
Is it worth choosing the EQB with 4MATIC?
If you often drive on slippery roads or rough terrain, four-wheel drive provides better grip and more power. For mostly city and highway driving, the EQB 250 or EQB 250+ are usually sufficient, as they typically cover more distance.
