The current Alfa Romeo GTV covers up to 761 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1976–1981 | Combustion | 540 |
| 1981–1986 | Combustion | 545 |
| 1995–1998 | Combustion | 729 |
| 1998–2003 | Combustion | 787 |
| 2003–2005 | Combustion | 761 |
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.
