Mercedes-Benz GLB
Mercedes-Benz GLC
The Mercedes-Benz GLC costs £15,000 more than the Mercedes-Benz GLB. For that premium it adds 25 miles more WLTP range and 160 kW more power. The Mercedes-Benz GLB is not just cheaper - it also offers 2 more seats (7 versus 5). On EVcarsguide's combined category scores, the Mercedes-Benz GLB comes out ahead overall.
The Mercedes-Benz GLB is £15,000 cheaper to buy. Running costs are almost identical - about £176 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Mercedes-Benz GLB comes out roughly £15,000 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 268 miles for the Mercedes-Benz GLB and 297 miles for the Mercedes-Benz GLC - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz GLC goes roughly 29 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 20-22 minutes.
The Mercedes-Benz GLB is the easier car for tight UK car parks: it is 52 mm narrower than the Mercedes-Benz GLC. In a standard 2,400 mm bay that leaves about 539 mm of total clearance for the Mercedes-Benz GLB and about 487 mm of total clearance for the Mercedes-Benz GLC. The Mercedes-Benz GLB also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Mercedes-Benz GLB and 84% for the Mercedes-Benz GLC. 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.
