Automobiles are a vital part of the modern world. They are used for both passenger & freight transportation. They have four to eight tires & are powered by internal combustion engines or electric motors. The branch of engineering which deals with the manufacture & technology of automobiles is known as automotive engineering.
Most modern cars use a internal combustion engine to power the wheels. The engine uses a type of fuel like gasoline, diesel or kerosene to run. When the fuel is burned it pushes a piston down and turns the wheels. The amount of energy (measured in kilowatts or horsepower) that the engine sends to the wheels is called its power.
The invention of the automobile greatly changed the nature of human society. Having your own car allows you to travel at your own pace and schedule without having to wait on a bus or taxi. It also gives you the freedom to stop wherever you want and whenever you like, so you can spend more time with your family.
Many of the most popular vehicles on the road today are SUVs and crossovers. These vehicles are a hybrid of sedans and trucks, with car-like handling and cargo space coupled with truck-like off-road capabilities and towing capacity.
However, sedans are still a popular choice for many drivers. Sedans have better gas mileage than most SUVs, and many of them offer advanced technology features. They are also less likely to be damaged in a crash than SUVs. In fact, the top sedans in our rankings have the highest reliability ratings and user-friendly infotainment systems.
