Smart #3
The Smart #3 costs £5,650 more than the MINI Aceman. For that premium it adds 75 kW faster peak rapid charging, 70 litres more boot space and 65 kW more power. On EVcarsguide's combined category scores, the MINI Aceman comes out ahead overall.
The MINI Aceman is £5,650 cheaper to buy. The MINI Aceman 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 MINI Aceman comes out roughly £5,930 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 159 miles for the MINI Aceman and 189 miles for the Smart #3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Smart #3 goes roughly 30 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 29-30 minutes.
The MINI Aceman is the easier car for tight UK car parks: it is 90 mm narrower than the Smart #3. In a standard 2,400 mm bay that leaves about 646 mm of total clearance for the MINI Aceman 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 MINI Aceman 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.
