There are three types of fuel efficiency ratings a car can receive. They are a Gallons per 100 miles (GPM) rating, a Combined Fuel Economy (CFE) rating, and a Displacement rating. Each of these is important to consider when shopping for a vehicle.
A gallons-per-100-mile rating is a no brainer for those looking to maximize their gas money. Not to mention, it’s a pretty good way to make sure you don’t leave your tank empty. This is especially helpful when you’re on the go and can’t refuel for an extended period.
The EPA has been using the gallons-per-100-mile indicator for a while now. While they haven’t yet officially announced it, they are planning to do so in the near future. In the meantime, you can use their website to convert a mileage number to a gallons-per-100-mile number. It’s actually quite simple, and you can do it right in your browser. You just need to know the way to spell it.
Gallons-per-100-miles is not the only measure used by the EPA. They’re also using a variety of other indicators to help shoppers choose which car is best suited for their needs. For example, you’ll get a number of the most efficient cars based on how often you drive or where you live. Another indicator is a vehicle’s electric mileage. If you’re planning to plug your car in, you might want to get a model that has a high plug-in factor.
While the EPA hasn’t rolled out the new gallons-per-100-miles rating on every car on the market, you’ll certainly find it on some. As an added bonus, it’s a better way to quantify the real cost of your next purchase.
Combined fuel economy
There are many types of combined fuel economy ratings. They include city and highway, MPGe, and MPG. All of these are based on gasoline vehicles. It is important to understand how the ratings are calculated and what they mean.
For example, if a new car advertisement says that a model has a 50-MPG rating, that means that it can travel approximately fifty miles on a gallon of gas. However, if the advertisement says that the same vehicle can reach 60-MPG, that is a twenty percent improvement.
According to the Federal Trade Commission, fuel economy claims should be clearly disclosed and the estimates used should be comparable. The FTC has found that many consumers expect a combined MPG to be lower than a highway MPG.
Some advertisements for new cars only provide a EPA highway MPG estimate. This may confuse consumers.
To avoid this, advertisers should disclose the EPA city MPG estimate in addition to the EPA highway MPG estimate. Similarly, advertisers should indicate that the value is a “EPA estimate” instead of a “test result” or “measurement” of the MPG.
When displaying the MPG of a new car, it is best to display the EPA highway MPG number and not a “miles per gallon.” That would mislead consumers into believing that the vehicle’s MPG rating is based on only highway driving.
Displacement affects fuel economy
Engine displacement is a relatively small but important component of the combustion process of your car. It is the sum of the volume of each cylinder and the amount of fuel and air mixture that goes into each cylinder. The larger the displacement, the higher the total power. Generally speaking, a larger engine has a bigger impact on fuel efficiency, although the opposite is true for a small engine.
In general, there are three main categories of displacement: horsepower, torque, and the number of cylinders. However, there are some other factors to consider. Specifically, what is the best displacement for your needs?
First, a large displacement is more resource intensive to produce. Secondly, a larger engine needs to be revved to generate the same amount of power. This is because the cylinders are smaller and need to be refilled more often. Finally, a high-displacement engine consumes more fuel than a low-displacement one.
Displacement is not always easy to change. For example, a low-displacement car could have a very tiny electric motor to offset the deactivated cylinders. Another issue to consider is the power and torque needs of your fleet.
A high-displacement engine produces more power and torque. But, because the cylinders are larger and more fuel is needed, the overall efficiency is usually lower. So, if you want to save money, opt for a low-displacement vehicle.
