Smart #3
The Nissan LEAF costs £2,039 more than the Smart #3. For that premium it adds 173 miles more WLTP range and 67 litres more boot space. The Smart #3 is not just cheaper - it also offers 40 kW more power and a 1.8s quicker 0-62mph time. On EVcarsguide's combined category scores, the Nissan LEAF comes out ahead overall.
The Smart #3 is £2,039 cheaper to buy. The Nissan LEAF is cheaper to charge, roughly £136 a year versus £192 for the Smart #3, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Smart #3 comes out roughly £1,759 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 313 miles for the Nissan LEAF and 189 miles for the Smart #3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Nissan LEAF goes roughly 124 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 30-30 minutes.
The Nissan LEAF is the easier car for tight UK car parks: it is 34 mm narrower than the Smart #3. In a standard 2,400 mm bay that leaves about 590 mm of total clearance for the Nissan LEAF and about 556 mm of total clearance for the Smart #3.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Nissan LEAF and 84% for the Smart #3. 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.
