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.
Kick it
I had this question for my homework. The answer is 30-35%
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.
an hydro power car saves aboout 49% of energy
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 average vehicle price as of 2012 is $30,100.
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
yes at 36 mpg it is a very efficient car
