The current Hyundai Sonata covers up to 1,167 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1989–1993 | Combustion | 844 |
| 1993–1996 | Combustion | 985 |
| 1996–1998 | Combustion | 739 |
| 1998–2001 | Combustion | 730 |
| 2001–2005 | Combustion | 722 |
| 2005–2008 | Combustion | 1,066 |
| 2008–2010 | Combustion | 1,167 |
Range is calculated from each variant’s fuel tank capacity and combined-cycle consumption (tank ÷ consumption × 100), for the best-range variant in each generation — real-world range varies with driving style and conditions. Figures outside a plausible range for the tank size are excluded.
