Toyota bZ4X vs Vauxhall Mokka

The Toyota bZ4X costs £7,490 more than the Vauxhall Mokka. For that premium it adds 29 miles more WLTP range, 50 kW faster peak rapid charging and 142 litres more boot space. On EVcarsguide's combined category scores, the Toyota bZ4X comes out ahead overall.

The Vauxhall Mokka is £7,490 cheaper to buy. Running costs are almost identical - about £144 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Vauxhall Mokka comes out roughly £7,370 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 230 miles for the Toyota bZ4X and 173 miles for the Vauxhall Mokka - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Toyota bZ4X goes roughly 57 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 30-30 minutes.

The Toyota bZ4X is the easier car for tight UK car parks: it is 127 mm narrower than the Vauxhall Mokka. In a standard 2,400 mm bay that leaves about 540 mm of total clearance for the Toyota bZ4X and about 413 mm of total clearance for the Vauxhall Mokka. The Vauxhall Mokka also turns in a 0.8 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 Toyota bZ4X and 84% for the Vauxhall Mokka. 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. Both batteries carry a 8-year manufacturer warranty.
