Mercedes-Benz GLB vs Renault Scenic

The Mercedes-Benz GLB costs £9,105 more than the Renault Scenic. For that premium it adds 170 kW faster peak rapid charging, 40 kW more power and 2 more seats (7 versus 5). On EVcarsguide's combined category scores, the Mercedes-Benz GLB comes out ahead overall.

The Renault Scenic is £9,105 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 Renault Scenic comes out roughly £9,065 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 274 miles for the Renault Scenic - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 20 minutes in the Mercedes-Benz GLB and 37 in the Renault Scenic, so the Mercedes-Benz GLB loses less time at each stop.

The two are within 3 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 539 mm of total clearance for the Mercedes-Benz GLB and about 536 mm of total clearance for the Renault Scenic.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Mercedes-Benz GLB and 84% for the Renault Scenic. 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.
