The current Porsche Boxster covers up to 810 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1996–2002 | Combustion | 598 |
| 2002–2005 | Combustion | 660 |
| 2005–2009 | Combustion | 688 |
| 2009–2012 | Combustion | 730 |
| 2012–2016 | Combustion | 810 |
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.
