How many Litres does a car use per 100km?

The average car uses between 5 to 10 litres of fuel per 100 kilometres driven, depending on various factors such as the vehicle's make, model, engine size, and driving conditions. However, the exact fuel consumption can vary significantly based on individual driving habits and the specific car being used.


Understanding Fuel Consumption in Cars


Fuel consumption in cars is typically measured in litres per 100 kilometres (L/100km) or miles per gallon (MPG). This metric provides a standardized way to compare the efficiency of different vehicles and helps consumers make informed decisions when purchasing a new car.


The factors that can influence a car's fuel consumption include:



  • Engine size and type: Larger engines and less efficient engine types, such as V8s, generally consume more fuel than smaller, more efficient engines like 4-cylinder models.

  • Driving conditions: Factors like traffic, road conditions, and driving style (e.g., aggressive acceleration and braking) can significantly impact fuel consumption.

  • Vehicle weight: Heavier vehicles, such as SUVs and trucks, tend to have higher fuel consumption compared to lighter, more compact cars.

  • Aerodynamics: The shape and design of a vehicle can affect its aerodynamic efficiency, which influences fuel consumption.

  • Fuel type: Different fuel types, such as gasoline, diesel, or alternative fuels, can have varying energy densities and affect a car's fuel efficiency.


It's important to note that the fuel consumption figures provided by manufacturers are typically based on standardized testing conditions, which may not accurately reflect real-world driving experiences. Actual fuel consumption can vary significantly depending on individual driving habits and conditions.


Improving Fuel Efficiency


To improve a car's fuel efficiency, drivers can adopt the following strategies:



  • Maintain proper tire pressure: Underinflated tires can increase rolling resistance, leading to higher fuel consumption.

  • Avoid excessive idling: Idling a car's engine can waste fuel, so it's best to turn off the engine if you're stopped for more than a minute.

  • Drive at moderate speeds: Fuel efficiency typically decreases at higher speeds, so maintaining a moderate and consistent speed can help improve fuel economy.

  • Remove unnecessary weight: Carrying extra weight in the vehicle can increase fuel consumption, so it's best to remove any unnecessary items.

  • Regular maintenance: Keeping the car well-maintained, including regular oil changes and tune-ups, can help optimize its fuel efficiency.


By understanding the factors that influence fuel consumption and adopting fuel-efficient driving habits, car owners can maximize their vehicle's fuel efficiency and reduce their overall fuel costs.

How many litres does it take to drive 100km?


For cars it is between about 6 litres per 100km for a small efficient car used in rural conditions up to about 20 litres per 100km for a large SUV used in city traffic.

How much is 40 mpg in litres?


—— 40 miles per gallon is 40 miles per 3.785 liters or 10.57 miles per liter. 10.57 miles per liter.



What is the liters per 100km of a car?


However, as a rule of thumb, a small city hatchback should be able to achieve an average fuel consumption of around six to seven litres per 100km, a mid-sized SUV will be closer to eight or nine litres per 100km and a full-sized family SUV will use closer to 10 litres per 100km in the real world.



Is 7 litres per 100km good?


What we consider to be good fuel economy based on our habits and petrol budget may seem quite high compared to yours. One source recommends that good fuel efficiency is approximately 5-6L/100km for a small car, 7-8L/100km for a ute, and 8-9L/100km for an SUV.



What is 12km per liter in mpg?


For this we need to convert kilometers into miles and liters into gallons. As there are 0.621371 miles in each kilometer, we have 0.621371×12=7.456452 miles. 7.4564520.264172 miles per gallon or 28.23 miles per gallon.



Which car has the lowest fuel consumption?


Our top 10 most fuel efficient cars of 2025

  • Škoda Octavia (2020 – onwards) – 67.3mpg.
  • Volkswagen Golf (2020 – onwards) – 60.9-63.1mpg.
  • Hyundai IONIQ (2019) - 62.8mpg.
  • Toyota Corolla (2019 – onwards) - 57.6-62.8mpg.
  • Renault Clio (2020 – onwards) – 67.2mpg.
  • Kia Niro (2020) - 53.3-61.4mpg.
  • Peugeot 108 (2014 - 2022) – 58.9mpg.



How many litres per 100km does my car use?


You will need the number of litres it took to fill your tank since the last time you filled it, and the number of kilometres you traveled in between fills. The calculation is: litres / distance * 100 = l/100km. For example: 57 litres / 635 km * 100 = 8.98l/100km.



Is 12 litres per 100km good?


Anything under eight L/100km is excellent. If a car uses eight to 12 litres of gas for every 100 kilometres, that's pretty good. This usually fits most medium-sized SUVs and some lighter trucks. Cars that use 12 to 14 litres for every 100 kilometres are average—not too bad, not too great.



How many litres of fuel per 100km?


Let's take a look at what good fuel efficiency looks like for different types of vehicles: Small car: 5-6L/100km. Ute: 7-8L/100km. SUV: 8-9L/100km.
