The Tesla Model 3 costs £4,030 more than the Smart #3. For that premium it adds 130 miles more WLTP range, 25 kW faster peak rapid charging and 312 litres more boot space. On EVcarsguide's combined category scores, the Tesla Model 3 comes out ahead overall.
The Smart #3 is £4,030 cheaper to buy. The Tesla Model 3 is cheaper to charge, roughly £144 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 £3,790 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 189 miles for the Smart #3 and 229 miles for the Tesla Model 3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Tesla Model 3 goes roughly 40 miles further between charging stops.
The Smart #3 is the easier car for tight UK car parks: it is 89 mm narrower than the Tesla Model 3. In a standard 2,400 mm bay that leaves about 556 mm of total clearance for the Smart #3 and about 467 mm of total clearance for the Tesla Model 3.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Smart #3 and 92% for the Tesla Model 3. That gives the Tesla Model 3 a modest edge in retained real-world range. The Tesla Model 3's LFP-type pack tolerates daily 100% charging, while the Smart #3's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
