Toyota bZ4X
The Toyota bZ4X costs £2,150 more than the Smart #5. For that premium it adds 33 miles more WLTP range. The Smart #5 is not just cheaper - it also offers 178 litres more boot space, 100 kW more power and a 1.5s quicker 0-62mph time. On EVcarsguide's combined category scores, the Toyota bZ4X comes out ahead overall.
The Smart #5 is £2,150 cheaper to buy. The Toyota bZ4X is cheaper to charge, roughly £152 a year versus £200 for the Smart #5, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Smart #5 comes out roughly £1,910 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 202 miles for the Smart #5 and 267 miles for the Toyota bZ4X - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Toyota bZ4X goes roughly 65 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 60 mm narrower than the Smart #5. In a standard 2,400 mm bay that leaves about 540 mm of total clearance for the Toyota bZ4X and about 480 mm of total clearance for the Smart #5.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the Smart #5 and 84% for the Toyota bZ4X. That gives the Smart #5 a modest edge in retained real-world range. The Smart #5's LFP-type pack tolerates daily 100% charging, while the Toyota bZ4X's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
