It depends which car it is, electrical cars are usually more expensive.
Petrol
it is
Electric cars generally have more efficient engines than petrol cars. Electric motors convert over 60% of electrical energy from the grid to power at the wheels, while internal combustion engines in petrol cars typically convert only about 20% of the energy stored in fuel into usable power. Additionally, electric vehicles benefit from regenerative braking, which further enhances their efficiency. Overall, electric cars are more energy-efficient and environmentally friendly compared to petrol cars.
petrol is used to drive your car or to help power different types of electric!
Either by Petrol/Nitro or electric.
Electric cars are better for the environment. Whereas, the fuel vehicle emits harmful gases like carbon due to petrol or diesel. But, electric vehicles produce fewer greenhouse gases and air pollution than petrol. That's why interest in purchasing an electric vehicle is increasing.
because
A hybrid is generally a car which runs on petrol and electric (powered by batteries)
The main difference is in hybrid cars there are a small petrol engine and a electric motor. When the car is driving along at slower speeds the Electric motor is driving the car while the petrol engine recharges the battery but when the speed is greater the Engine And Electric Motor Drives The Car
how much petrol will a car use (enginne two liters)
Depends on the model of the car
It is completely electric, with no petrol/diesel engine at all.
