Is 7.3 l/100km good?

Yes, 7.3 liters per 100 kilometers (l/100km) is generally considered a good fuel efficiency rating for a vehicle. This means the vehicle can travel 100 kilometers while consuming only 7.3 liters of fuel, which is an efficient and economical performance.


Understanding Fuel Efficiency Ratings


Fuel efficiency, also known as fuel economy, is a measure of how much fuel a vehicle consumes per unit of distance traveled. In the metric system, fuel efficiency is commonly expressed in liters per 100 kilometers (l/100km), which represents the amount of fuel (in liters) required to travel 100 kilometers.


The lower the l/100km value, the more fuel-efficient the vehicle is. A rating of 7.3 l/100km indicates that the vehicle can travel 100 kilometers while using only 7.3 liters of fuel, which is considered a good and efficient performance.


Factors Affecting Fuel Efficiency


Fuel efficiency can be influenced by various factors, including:



  • Vehicle type and size: Smaller, lighter vehicles tend to be more fuel-efficient than larger, heavier vehicles.

  • Engine technology: Advancements in engine design, such as turbocharging, direct injection, and hybrid systems, can improve fuel efficiency.

  • Driving behavior: Aggressive acceleration, high speeds, and frequent braking can decrease fuel efficiency.

  • Road conditions: Driving on well-maintained roads with minimal traffic and hills can improve fuel efficiency.

  • Environmental factors: Temperature, wind, and altitude can also affect a vehicle's fuel consumption.


Given the range of factors that can influence fuel efficiency, a rating of 7.3 l/100km is generally considered a good and efficient performance for a vehicle.


Comparing Fuel Efficiency Ratings


To put the 7.3 l/100km rating into perspective, consider the following comparisons:



  • A less efficient vehicle might have a rating of 10 l/100km or higher.

  • A highly efficient hybrid or electric vehicle could have a rating as low as 2-3 l/100km.

  • The average fuel efficiency of new vehicles in the United States is around 8-9 l/100km.


So, a 7.3 l/100km rating would be considered above average and a good indicator of the vehicle's fuel efficiency and cost-effectiveness for the driver.

Is 7.3L/100km good?


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). This is how many litres of fuel the car needs in order to travel 100km. You'll often see it referred to as 'fuel economy'.



How does driving style impact L/100km?


The study of [16] shows also that smooth acceleration without sudden speed fluctuations (typical of economical driving styles), could decrease fuel consumption up to 4.83 l/ 100 km. In contrast, a more dynamic style with frequent and higher accelerations could increase fuel consumption up to 6.15 l/100 km. ...



What is a good average L/100km?


A good average fuel consumption is generally considered to be under 6 to 8 litres per 100 km (L/100km), with what is considered "good" depending heavily on the vehicle type. For smaller cars, 5–7 L/100km is a good target, while for SUVs or larger vehicles, 8–10 L/100km might be considered good or average. 
By vehicle type

  • Small cars: 5–7 L/100km is a good range for a petrol hatchback, with some hybrids achieving under 5 L/100km. 
  • Mid-size cars/SUVs: 7–9 L/100km is a more realistic goal. 
  • Large SUVs/trucks: A good target is around 8–10 L/100km for an ideal scenario, though many large vehicles consume 10–15 L/100km or more in real-world conditions. 
  • Hybrids: These can achieve as low as 4 L/100km, depending on the model and driving conditions. 

General guidelines
  • Excellent: Below 6 L/100km for most vehicles. 
  • Good: 6–8 L/100km for cars, or 8–12 L/100km for larger SUVs and light trucks. 
  • Average: 8–10 L/100km is often considered average for a car, but is a good target for some larger vehicles. 
  • Poor: Over 12 L/100km is generally considered poor fuel economy. 



Is a 7.3 a million mile motor?


These engines are known to surpass 300,000 miles when properly maintained—and many even reach the half-million-mile mark without significant issues. Ford designed the 7.3L with a robust cast-iron block, forged-steel connecting rods, and simple, durable components that can withstand the demands of heavy-duty use.
