Costs and real consumption: Mercedes GLB 250 4-Matic

The Mercedes GLB 250 4-Matic, which costs 55,044 euros, comes to the consumption check.

Did you know that this GLB 250 with all-wheel drive drives really well? The Mercedes is comparatively light, flat and strong. Its cultivated two-liter turbo, which harmonises well with the eight-speed DCT, brings it to 224 hp and 350 Nm and thus quickly gets the SUV going. Thanks to its angular body and large windows, it gives its occupants an all-round view that is very good for an SUV. Only the somewhat short rear seat diminishes the joy in the handsome interior. It is well known that the all-encompassing MBUX infotainment with its easy-to-read instruments, large touchscreen and sophisticated voice control is hard to beat. And what about the fuel and maintenance costs?

Our test consumption

Mercedes specifies a WLTP standard consumption of 7.7 liters Super for the GLB 250 4-Matic . He moves away from this value in everyday life. We have determined an average consumption of 9.1 liters, which causes fuel costs of 14.56 euros per 100 kilometers. On the Eco lap, the Mercedes consumed 6.7 liters, while it consumed 9.0 liters on the commuter route. If the Mercedes was moved in a sporty manner, consumption rose to 11.7 liters. The fuel costs are calculated using the daily updated fuel price on our partner portal mehr-tanken.de (09/09/2021 /Super: 1.60 euros/litre).

Monthly maintenance costs

If you drive as resource-efficiently as we do on our eco tour, you reduce the fuel costs for 100 kilometers to 10.72 euros. The rather violent gait resulted in a sum of 18.72 euros. The vehicle tax costs 232 euros per year for the Mercedes, the liability insurance is 477 euros. Partial and fully comprehensive insurance cost an additional 138 and 640 euros respectively. Monthly maintenance costs of 329 euros are paid by those who drive the Mercedes 15,000 kilometers a year. If the mileage is doubled, the sum increases to 596 euros. We leave out the loss in value in this calculation.

How to test

The auto motor und sport test consumption consists of three differently weighted consumption drives. So-called “commuter consumption” accounts for 70 percent. This is a journey from home to work, which averages 21 kilometers. A particularly economical, approx. 275-kilometre-long eco-lap is included in the rating with 15 percent. The remaining 15 percent is accounted for by the sports driver lap. The length is roughly the same as the eco lap, but the route includes a larger proportion of motorway and thus higher speeds on average. The basis for calculating the fuel costs is always the price quoted on the "more tanken" portal on the day the article was created.

The monthly maintenance costs include maintenance, wear part costs and vehicle taxes assuming an annual mileage of 15,000 and 30,000 kilometers without loss of value. The basis for the calculation is the test consumption, a three-year holding period, no-claims class SF12 for liability and fully comprehensive insurance with Allianz including discounts for garage parkers and the restriction to certain drivers (not under 21). At Allianz, SF12 offers a discount rate of 34 percent for liability and 28 percent for comprehensive insurance.


In the auto motor and sport test consumption, the 55,044 euro Mercedes GLB 250 4Matic with 224 hp ended up with an average value of 9.1 liters Super per 100 kilometers. This means that the fuel costs over this distance are 14.56 euros. The monthly maintenance costs are 329 euros (15,000 km annual mileage) or 596 euros (30,000 km annual mileage).
