Which of the following requires the average fuel economy of covered vehicles to be 35 miles per gallon by 2020?
This new energy legislation, the Energy Independence and Security Act of 2007, raised the fuel economy standards of America’s cars, light trucks, and SUVs to a combined average of at least 35 miles per gallon by 2020—a 10 mpg increase over 2007 levels—and required standards to be met at maximum feasible levels through …
What are the factors governing the fuel economy?
While the ratings are achievable if you drive with fuel efficiency in mind, it’s important to remember that five factors can have a dramatic effect on your fuel consumption: Driving behaviour: Rapid acceleration, speeding, driving at inconsistent speeds and even extended idling can increase your fuel consumption.
What is a reasonable fuel consumption?
The generally accepted standard has risen from a consumption of around 8.1 to 7.1 litres per 100km (35-40mpg) in the past to more like 5.6 to 5.1 litres (50-55mpg). As a rule of thumb, vehicles listed at less than 6.0 litres/100km are considered to have ‘good’ MPG.
What does CAFE fuel standards mean?
Corporate Average Fuel Economy
NHTSA’s Corporate Average Fuel Economy (CAFE) standards regulate how far our vehicles must travel on a gallon of fuel. NHTSA sets CAFE standards for passenger cars and for light trucks (collectively, light-duty vehicles), and separately sets fuel consumption standards for medium- and heavy-duty trucks and engines.
What is fleet fuel economy?
At the fleet level, fuel efficiency refers to how efficient your entire fleet of vehicles is.
Why is corporate average fuel economy important?
First enacted by Congress in 1975, the purpose of CAFE is to reduce energy consumption by increasing the fuel economy of cars and light trucks. The CAFE standards are fleet-wide averages that must be achieved by each automaker for its car and truck fleet, each year, since 1978.
What factors decide fuel quality?
Cetane number is the most important and universally accepted ignition quality test. The cetane number test uses a standard single cylinder variable compression ratio diesel engine. Cetane index is a calculated value, which is derived from relatively easily measured fuel properties.
What are the factors of fuel?
Numerous factors alter how your car uses fuel, making the engine more or less efficient….How Your Driving Affects Fuel Economy
- Excessive Short Trips.
- Frequent Cold Weather Travel.
- Heavy Braking or Acceleration.
- High Vehicle Weight or Towing Weight.
- Speeding.
What is good fuel economy per 100km?
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’.
Is 12 litres per 100km good?
In general, 5 to 8 litres per 100 km would be considered a good fuel efficiency, 8 to 12 litres per 100 km would be average, and more than 12 litres per 100 km would be considered a relatively low fuel efficiency.
How are cafes enforced?
CAFE standards are administered by the Secretary of Transportation, Pete Buttigieg, via the National Highway Traffic Safety Administration.
What are the fuel economy standards?
Today, the U.S. fuel economy program technically includes two standards that are overseen by different agencies under different laws. The Corporate Average Fuel Economy, or CAFE, standard is set by the Department of Transportation’s National Highway Traffic Safety Administration, or NHTSA.
How many MPG will your car get under Obama’s fuel economy standards?
While the standards are often summarized by a single number, such as Obama’s 2025 goal of 54.5 mpg as an average across all vehicles, that is simply an estimate of what the agency expects under the program.
What is NHTSA’s corporate average fuel economy?
NHTSA’s Corporate Average Fuel Economy (CAFE) standards regulate how far our vehicles must travel on a gallon of fuel. NHTSA sets CAFE standards for passenger cars and for light trucks (collectively, light-duty vehicles), and separately sets fuel consumption standards for medium- and heavy-duty trucks and engines.
What does NHTSA regulate for fuel economy?
NHTSA sets CAFE standards for passenger cars and for light trucks (collectively, light-duty vehicles), and separately sets fuel consumption standards for medium- and heavy-duty trucks and engines. NHTSA also regulates the fuel-economy window stickers on new vehicles.
