The current Renault Laguna covers up to 1,193 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1994–1998 | Combustion | 917 |
| 1998–2001 | Combustion | 1,200 |
| 2001–2005 | Combustion | 1,296 |
| 2005–2007 | Combustion | 1,214 |
| 2007–2010 | Combustion | 1,294 |
| 2010–2013 | Combustion | 1,269 |
| 2013–2015 | Combustion | 1,193 |
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.
