The current Suzuki Grand Vitara covers up to 971 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1998–2005 | Combustion | 1,000 |
| 1999–2005 | Combustion | 767 |
| 2001–2004 | Combustion | 611 |
| 2004–2006 | Combustion | 825 |
| 2005–2008 | Combustion | 857 |
| 2008–2012 | Combustion | 943 |
| 2012–2015 | Combustion | 971 |
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.
