Frequently asked questions
Is the Mercedes-Benz EQB worth the extra £15,145 over the Nissan ARIYA?

Which is cheaper to own over 5 years, the Mercedes-Benz EQB or the Nissan ARIYA?
The Nissan ARIYA is £15,145 cheaper to buy. Running costs are almost identical - about £168 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Nissan ARIYA comes out roughly £15,225 cheaper overall. 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 Nissan ARIYA like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 214 miles for the Mercedes-Benz EQB and 209 miles for the Nissan ARIYA - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 30-32 minutes.
Which is easier to park and drive in town, the Mercedes-Benz EQB or the Nissan ARIYA?
The two are within 16 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQB and about 550 mm of total clearance for the Nissan ARIYA.
Which battery will hold up better as a used buy, the Mercedes-Benz EQB or the Nissan ARIYA?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Mercedes-Benz EQB and 84% for the Nissan ARIYA. 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.
