The current Mercedes-Benz SL covers up to 787 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.

| 2001–2006 | Combustion | 696 |
| 2006–2008 | Combustion | 777 |
| 2008–2012 | Combustion | 860 |
| 2012–2016 | Combustion | 956 |
| 2016–2020 | Combustion | 844 |
| 2022–present | Combustion | 787 |
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.
