How does the EPA test fuel economy?

How does the EPA test fuel economy?

The EPA doesn’t just drive the vehicle to determine how many miles per gallon it gets. Both fuel economy tests are performed with the vehicle’s air conditioning and other accessories turned off. Throughout the test, a hose is connected to the vehicle’s tailpipe and collects the engine’s exhaust.

How do you know if your fuel economy is good?

Remember, the lower the litres per 100 kilometres (L/100 km) rating, the better the fuel consumption. And the higher the miles per gallon (mpg) rating, the better the fuel use.

What is fuel consumption tester?

Get Latest Price. Measurement of a vehicle’s consumption under real conditions while driving. – For Petrol and Diesel systems with or without return. – Calibrated flow sensors guarantee a high degree of accuracy.

How do you calculate fuel economy?


  1. Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one.
  2. Divide the miles traveled by the amount of gallons it took to refill the tank. The result will be your car’s average miles per gallon yield for that driving period.

Is 18 MPG good for a car?

Don’t expect to attain higher than 20 mpg overall with a non-hybrid, and most offer less than 30 mpg on the highway. The best fuel-efficient non-electric vehicles get the following EPA-estimated combined numbers: Standard Pickup: Ford F150 Pickup 2WD Diesel gets 25 mpg. Small SUV: Toyota RAV4 Hybrid AWD gets 40 mpg.

What is highway fuel economy?

What Is MPG? Highway MPG: the average a car will get while driving on an open stretch of road without stopping or starting, typically at a higher speed. City MPG: the score a car will get on average in city conditions, with stopping and starting at lower speeds.

How do you do a fuel consumption test?

Divide mileage by fuel usage to see your car’s fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).

How can I reduce the fuel consumption of my car?

13 Tips to Reduce Fuel Consumption

  1. Drive only when needed.
  2. Make sure the gas cap is on tight.
  3. Avoid idling.
  4. Accelerate and break steadily.
  5. Drive the speed limit.
  6. Coast when possible.
  7. Use cruise control on the highways.
  8. Make your car more aerodynamic.

What is a good fuel economy?

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’.

What is classed as good fuel economy?

You need to consider your needs, and consider your budget. But with all that being said, a good MPG figure to aim for is anything between 50 and 60MPG. This will ensure that your car is efficient and economical, which means low running costs and car tax rates.

What does the EPA highway fuel economy test mean?

The Highway Fuel Economy Driving Schedule (HWFET) represents highway driving conditions under 60 mph. EPA Highway Fuel Economy Test Driving Schedule (Click image to see larger.)

How is the fuel economy of a car measured?

For vehicles using carbon-based fuels (e.g., gasoline, diesel, natural gas, etc.), a hose is connected to the tailpipe to collect the engine exhaust during the tests. The carbon in the exhaust is measured to calculate the amount of fuel burned during the test. This is more accurate than using a fuel gauge.

How does the Dot get fuel economy data?

DOT receives the manufacturers’ fleet average fuel economy from EPA, and determines if manufacturers are complying with the federal corporate average fuel economy (CAFE) standards. EPA provides IRS with the fuel economy data for vehicles which may be subject to the Gas Guzzler tax penalty.

How does the EPA test a car speed?

EPA tests vehicles by running them through a series of driving routines, also called cycles or schedules, that specify vehicle speed for each point in time during the laboratory tests.
