Fuel Efficiency and Losses in Car Designs by Thomas Yoon
Our previous article talks about careful planning in order to save unnecessary trips, adopting carpooling to share out the costs, avoiding traffic jams at peak hours to avoid unproductive burning of fuel, avoiding carrying unnecessary loads and other tips that will help in some way or another to save on fuel consumption.
I did touch a bit on more efficient smaller cars that are lighter and do not have to carry excess and unproductive weights in their frames, chassis and body. However, very often, these smaller and lighter cars are not as comfortable to ride compared to the heavier ones.
So, in this article, I won't compare lighter cars with heavier cars. I will explore with you the kinds of efficiency losses that are quite typical even within the same class of cars.
If you look through the sales brochures of new cars, very often you can find figures that indicate the fuel efficiency of the car. With that information, you can compare and find out the most fuel efficient vehicle that will meet your needs. Even within a specific size class, there is a tremendous range of MPG (miles per gallon) performance that you can find.
Just for example, for the same model year compact cars, we can find fuel efficiency ranges from 21 to 48 MPG. If you choose the 48 MPG car, you could be saving hundreds of dollars in fuel costs each year. I think that should be an important point to note when buying a new car.
Having decided on the model that fulfils your needs, you might be interested to know where the energy goes.
