Conventional cars are vehicles powered primarily by internal combustion engines that run on gasoline or diesel fuel. These engines convert fuel into energy, which propels the car forward. Conventional cars are widely used for personal transportation and are known for their relatively low initial purchase cost compared to alternative fuel vehicles. Most conventional cars have a standard design that includes four wheels, a steering wheel, and seating for passengers. They typically feature a variety of technologies for comfort and safety, such as air conditioning, anti-lock brakes, and airbags. However, they also contribute to air pollution and greenhouse gas emissions, raising environmental concerns.
