Smart #3
The Smart #3 costs £5,245 more than the Citroën ë-C4. For that premium it adds 50 kW faster peak rapid charging, 100 kW more power and a 4.2s quicker 0-62mph time. The Citroën ë-C4 is not just cheaper - it also offers lower energy use, 153 versus 172 Wh/km. On EVcarsguide's combined category scores, the Citroën ë-C4 comes out ahead overall.
The Citroën ë-C4 is £5,245 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 Citroën ë-C4 comes out roughly £5,365 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 161 miles for the Citroën ë-C4 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 28 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 30-30 minutes.
The Citroën ë-C4 is the easier car for tight UK car parks: it is 44 mm narrower than the Smart #3. In a standard 2,400 mm bay that leaves about 600 mm of total clearance for the Citroën ë-C4 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 Citroën ë-C4 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. Both batteries carry a 8-year manufacturer warranty.
