Powered by an engine and equipped with four or more wheels, a car is a non-track-bound vehicle. More details about vehicles are as follows: Vehicle Types: Vehicle types refer to a classification based on common characteristics, intended use, and functionality. Examples include sedans, trucks, buses, trailers, and incomplete vehicles, each representing a distinct category. Others: Heavy-duty vehicles have a length of 6 meters or more and a total mass of 12,000 kg or more. Medium-duty vehicles are 6 meters or more in length with a total mass between 4,500 kg and 12,000 kg. Light-duty vehicles are less than 6 meters in length with a total mass under 4,500 kg. Mini vehicles are 3.5 meters or less in length with a payload capacity of 1,800 kg or less.
I've researched this, simply put a car is a metal box on four wheels that runs on fuel or electricity. But the formal definition must include these key points: first, it must have its own power system, whether an engine or electric motor; second, it requires a steering wheel for directional control; third, it must be legally operable on public roads with license plates. Most importantly, safety structures like seat belts and crash beams are essential. Nowadays, new energy vehicles also qualify as cars - though they charge electrically, they meet all standards. Remember, a car isn't a toy vehicle nor a low-speed electric cart; it must comply with national motor vehicle standards to be considered a real automobile.
Once, while helping a neighbor review a car purchase contract, I noticed the details. Legally, a car is classified as a motor vehicle, which must have at least four wheels (motorcycles don't count), operate without relying on tracks, and primarily function to carry passengers or transport goods. Key indicators to look for include: a maximum design speed exceeding 50 km/h; a total vehicle weight below 3.5 tons; and an engine displacement or motor power meeting the national minimum standards. Common vehicles like sedans, SUVs, and MPVs qualify, but agricultural tractors do not. When buying a car, remember to check the vehicle certification, which clearly defines whether it falls under the car category.
From an old-timer's driving experience, a car is essentially a mobile tool with an engine. Three core elements are indispensable: the driver's seat, independent suspension, and an enclosed cabin. The GAZ vehicles I drove in my youth also counted as cars—though they ran on diesel, they could carry ten people. Even those tiny two-seater electric cars today qualify, as long as they can cruise on the highway. Just don’t confuse them with three-wheeled motorcycles—a car must have four wheels with independent steering. Additionally, the vehicle identification number (VIN) is a car's ID card, and the first letter of the VIN code represents the manufacturer.
