A320-200:
- Fuel burn per hour (block fuel): 1,950 - 2,350 kg (4,300 - 5,180 lbs)
- Fuel burn per passenger per 100 km (SFC): 2.6 - 3.0 liters (0.68 - 0.79 US gallons)
A320neo:
- Fuel burn per hour (block fuel): 1,550 - 1,850 kg (3,420 - 4,080 lbs)
- Fuel burn per passenger per 100 km (SFC): 2.0 - 2.4 liters (0.53 - 0.63 US gallons)
The A320neo family of aircraft (including the A319neo, A320neo, and A321neo) incorporates various fuel-saving technologies and aerodynamic improvements, resulting in better fuel efficiency compared to the older A320ceo (current engine option) variants.
It's important to note that these figures are approximate and can vary depending on the specific operating conditions and performance metrics used by different airlines.
