Because there is more mass to move and it takes more gas to move more mass.
When the car is loaded, more energy is needed to propel it. A loaded car feels sluggish so you have to press the gas pedal more, so more fuel is used.
Yes it will. A/c will put another load on your engine which will cause it to want more fuel.
The air conditioning compressor is belt driven from the engine. While compressor is on it adds another load to the engine. Therefore; yes it does require additional fuel to be used to compensate for the additional engine load.
It's a more efficient fuel.
by the load of the car
no Sorry to have to correct you but yes it does. When you turn on the heater in a car two extra loads are added to the engine. First the heater fan is turned on, This adds an extra load to the alternator, which in turn puts more drag on the engine, using more fuel. Is the extra amount of fuel used large enough to be detectable? yes, but only after you have run the heat for a long time. The second additional load, is not universal. On some cars there is an electric heating element which is turned on when the heat is turned up to high. When this element is being run, it put a pretty big load on the alternator so when it is running there is definitely a drop in MPG for the car.
Torque is used when taking off or pulling a load. The more torque you have the faster the car will take off.
Of course, the more weight the car has to push the slower it will go so to keep the same pace you will need more gas intake to go faster.
A car has to be fuel efficient. It means it has to completely burn the fuel.
for their size, they get ok fuel effeciey. not as good as a car or passenger van. the more weight in the vehicle the more fuel is used. your style of driving also affects fuel usage
No, water is not a fuel.
Using potato chips in your car can help improve fuel economy by providing a source of energy that can be used as an alternative fuel. The oils in the potato chips can be converted into biodiesel, which can be used to power your car more efficiently, ultimately reducing fuel consumption and improving mileage.
