the increase in the speed of a car is proportional to the additional petrol put into the engine. Is it possible to accelerate a car without putting more/less petrol into engine?

yes by reducing weight (i.e if there is sand you can leak out sand through it ) during journey a thrust force will generate which will provide acceleration.

it is possible to accelerate a car without putting more or less petrol into the engine by driving the car in normal speed (like 40-60 km/h)
