The current Smart fortwo covers up to 160 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2004–2007 | Combustion | 702 |
| 2007–2012 | Combustion | 1,000 |
| 2012–2015 | Electric | 145 |
| 2014–2024 | Electric | 160 |
Range is the manufacturer-rated maximum for the longest-range variant in each generation. Electric generations use the rated battery range; combustion generations are calculated from tank capacity and combined-cycle consumption. Figures outside a plausible range are excluded rather than shown with a guessed correction.
