Is 4 litres per 100km good?

Yes, 4 litres per 100km is generally considered a good fuel efficiency for a vehicle. This means the vehicle is able to travel 100 kilometers on just 4 litres of fuel, which is an efficient and economical rate of fuel consumption.


Understanding Fuel Efficiency


Fuel efficiency, also known as fuel economy, is a measure of how much fuel a vehicle consumes per unit of distance traveled. It is typically expressed in litres per 100 kilometers (L/100km) or miles per gallon (MPG). The lower the L/100km value, the more efficient the vehicle is in terms of fuel consumption.


Factors that affect a vehicle's fuel efficiency include the engine size, weight of the vehicle, aerodynamics, driving conditions, and driving habits. Smaller, lighter vehicles with more aerodynamic designs tend to have better fuel efficiency compared to larger, heavier vehicles.


What is Considered Good Fuel Efficiency?


In general, a fuel efficiency of 4-6 L/100km is considered good for most passenger vehicles. Here's a breakdown of fuel efficiency ratings:



  • Excellent: 3 L/100km or less

  • Good: 4-6 L/100km

  • Average: 7-9 L/100km

  • Poor: 10 L/100km or more


Vehicles with a fuel efficiency of 4 L/100km or better are typically considered very efficient and economical to operate, as they use less fuel per kilometer traveled. This can result in significant cost savings for the vehicle owner over time.


Factors to Consider


It's important to note that fuel efficiency can vary depending on driving conditions, driving style, and other factors. Highway driving, for example, tends to be more fuel-efficient than stop-and-go city driving. Additionally, factors like vehicle load, weather conditions, and maintenance can all impact a vehicle's actual fuel consumption.


When evaluating a vehicle's fuel efficiency, it's best to consider the manufacturer's stated fuel efficiency ratings as a general guideline, but also to monitor your own real-world fuel consumption to get a more accurate picture of the vehicle's performance.

How many litres per 100km is good?


An excellent average fuel economy for a car is between five to eight litres per 100 kilometres, which reflects a balance of performance and fuel efficiency for most passenger vehicles.



What is the ideal fuel consumption speed?


55-80 km/h.
The optimum speed range for fuel consumption is typically 55-80 km/h. Fuel consumption starts ramping up above 80 km/h, partly because of air resistance. Obviously, sometimes you'll have to drive outside this range (such as when you're on a highway), but the more time you can spend in it, the better.



What is a good fuel consumption for a car?


A car that gets 40 miles per gallon of gasoline is considered good. Or a diesel that gets 45-50 miles per gallon. In the US car mileage is measured in miles per gallon which is the recriprocal of liters per 100 kilometers, with units conversion.



How many litres per 100km does the average car use?


A new car sold in Australia uses, on average, 6.9 litres of fuel per 100km compared with new cars in Europe and the US that use 3.5 litres and 4.2 litres, respectively. The difference means Australians are spending, on average, almost $1,500 a year on fuel compared with $886 in the US and $738 in Europe.



Is 4L 100km good?


What qualifies as fuel efficient, then? Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km).



What is the best L 100km?


  • Toyota Yaris Hybrid - 3.3L/100km.
  • Toyota Yaris Cross Hybrid - 3.8L/100km.
  • Toyota Corolla Hybrid - 4.0L/100km.
  • Kia Niro Hybrid - 4.0L/100km.
  • Suzuki Swift - 4.6L/100km.
  • Suzuki Ignis - 4.7L/100km.
  • Kia Picanto GT - 4.8L/100km.
  • Audi Q5 35 TDI - 4.8L/100km.



What is bad fuel economy l/100km?


Fuel efficiency, or fuel economy, refers to the distance a vehicle can travel on an amount of fuel. Vehicles listed as less than 6L/100 km are considered fuel-efficient. The 100 km is how many litres of fuel the car needs to travel 100 km. The lower the number of litres stated, the better the vehicle's fuel economy is.
