A lot of fuel is used to idle the car when stationary. The bigger the engine the more waste.
Engines have specific speeds when they are most efficient, when not running at that speed some fuel is wasted.
The energy to the wheels compared to the energy in the fuel is about 33%.
Engines with turbo chargers use less fuel when stationary while still have the power available when needed.
Hybrid cars can avoid some of the waste.
Cars with stop start engines when the car is stationary save fuel.
Electric cars has best efficiency from power in to power on the road.
What else can I help you with?
Do cars use energy?
Yes. A car converts the chemical energy in gasoline to kinetic energy of motion.More than 65% of the energy in the gasoline is wasted, and never becomes kinetic energy.
Do electric cars have an engine, and if so, how does it differ from traditional gasoline engines?
Electric cars do not have a traditional internal combustion engine like gasoline cars. Instead, they have an electric motor powered by a battery. This motor converts electrical energy into mechanical energy to drive the car, making it more efficient and environmentally friendly compared to gasoline engines.
What type of energy source is gasoline?
Gasoline is a Mechanical energy because gasoline can make cars move and cars are moving things.
What forms of wasted energy are produced by cars?
Heat is a waste energy from cars- from the engines and from the brakes.
Why is electrical energy wasted in cars?

How does the amount of work done on an automobile by its engine relate to the energy content of the gasoline?
The amount of work done on an automobile by its engine is directly related to the energy content of the gasoline used as fuel. Gasoline contains potential energy stored in its chemical bonds, which is released during combustion in the engine to produce work that moves the vehicle. The higher the energy content of the gasoline, the more work can be done by the engine.
How do you know that there is energy in gasoline?
Because it take energy to move a car and cars run on gasoline.
What are petrol powered cars?
The engine runs on gasoline.
What type energy produced energy for cars?
They can be electrical, diesel or gasoline
Why do cars need gasoline?
Cars need gasoline as a fuel to run. This compound is broken down into energy a car can use to run.
What does gasoline have that cars need?
Gasoline has chemical energy, that is easily converted to thermal energy and then to mechanical energy(movement), which is used to propel the car.
Hybrid cars are a combination of _____?
Gasoline engine and battery pack.
