The Suzuki Grand Vitara 2.4 typically achieves a combined fuel consumption rating of around 21 miles per gallon (mpg) or approximately 11 liters per 100 kilometers (L/100km) under mixed driving conditions[2]. Real-world averages reported by owners are often in the range of 18.5–22 mpg (about 12–13 L/100km), depending on model year, transmission, and driving style[1][3].
For example, data for the 2009–2012 models show:
- City driving: 17–19 mpg (13–14 L/100km)
- Highway driving: 23–26 mpg (9–10 L/100km)
- Average combined: 20–22 mpg (10.5–11.5 L/100km)
Manual transmission models sometimes achieve marginally better economy than automatics. However, some owners report real-world figures as low as 7.5–10.5 km/L (9.5–13.3 L/100km), especially in city traffic or with aggressive driving[5][7].
