most cars aren't ENERGY efficiant but some are GAS efficiant.
Most of the energy is lost as heat.
An energy efficient motor.
An energy efficient car can use gasoline, diesel, CNG, or electricity as a fuel.
I had this question for my homework. The answer is 30-35%
Kick it
very ineffecient unless maintained to factory specs. witch most are not.
If a car wasted 75% of it's energy, it's very efficient, as the energy is moving itself away from the car, which means the car would need more fuel to have more energy in the car, so it can get running again.
The average vehicle price as of 2012 is $30,100.
A typical car uses about 2,000 to 4,000 kilowatt-hours of energy per year during operation.
It means 25 percent of the energy consumed to power the car is turned into useful energy. So if it is 100% efficient, then you can say that it will go 4 times as fast as a 25% efficient car. (not realistic because there are a lot of other variables)
The most energy efficient car available is the Toyota Prius. Please see the following, for additional information: www.thesupercars.org/top-cars/most-fuel-efficient-cars
What is a typical length of a small car?
