Car Knowledge and Facts
The first gasoline-powered car was built in 1885 by Karl Benz. It had three wheels, a single-cylinder engine, and a wooden frame. This invention laid the foundation for the modern automotive industry. A car engine converts fuel into motion through internal combustion. Tiny explosions push pistons, which rotate the crankshaft and ultimately turn the wheels. Most cars today use four-stroke engines for efficiency and power. There are over a billion cars on Earth. The United States has one of the highest car ownership rates, while countries like Japan and Germany are known for engineering excellence in automotive design.Car tires are made of rubber and reinforced with steel belts. Tread patterns help grip the road, especially in wet or icy conditions. Proper tire pressure improves fuel efficiency and safety. Nowadays electric cars or EV's are also very popular. Electric cars use battery packs instead of fuel tanks. They produce zero tailpipe emissions and are quieter than traditional vehicles. Brands like Tesla, BYD, and Nissan have popularized EVs globally.
