Petrol cars are vehicles that use petrol, also known as gasoline, as their primary fuel source. They operate using an internal combustion engine, which ignites the petrol to create power that drives the car. These cars are popular for their relatively low initial cost and widespread availability of fuel. Despite their popularity, petrol cars contribute to air pollution and greenhouse gas emissions. Many countries are now encouraging the use of electric vehicles as an alternative to reduce environmental impact. The shift towards electric vehicles is part of a broader effort to combat climate change and promote sustainable transportation.
