These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Mercedes-Benz EQB and Mercedes-Benz GLB like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 214 miles for the Mercedes-Benz EQB and 268 miles for the Mercedes-Benz GLB - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz GLB goes roughly 54 miles further between charging stops. A rapid charge to 80% takes around 32 minutes in the Mercedes-Benz EQB and 20 in the Mercedes-Benz GLB, so the Mercedes-Benz GLB loses less time at each stop. That makes the Mercedes-Benz GLB the stronger long-distance car.
Which is easier to park and drive in town, the Mercedes-Benz EQB or the Mercedes-Benz GLB?

In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQB and about 539 mm of total clearance for the Mercedes-Benz GLB. The Mercedes-Benz GLB also turns in a 0.5 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Mercedes-Benz EQB or the Mercedes-Benz GLB?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Mercedes-Benz EQB and 84% for the Mercedes-Benz GLB. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
