What are the three major components of domestic cars?

The three major components of domestic cars refer to the chassis, engine, and transmission in a vehicle. Typically, the quality of these three components is the standard for measuring the quality of a car. The quality of these three major components has a significant impact on the overall quality of the car, so it is essential to pay attention to their quality when purchasing a car. Chassis: The chassis refers to the combination of the transmission system, running system, steering system, and braking system in a car. It supports and installs the car engine and its various components and assemblies, forming the overall shape of the car, bearing the engine power, and ensuring normal driving. Engine: The engine is the most important of the three major components and can be said to be the heart of the car. Engines are divided into several types based on the fuel used and the operation of the pistons. The most common types on the market are gasoline engines and diesel engines. The engine uses gasoline or diesel fuel to convert internal energy into kinetic energy, thereby propelling the car forward. An excellent car is inseparable from an excellent engine, and a car praised as excellent must have an excellent engine. The engine is to the car what the heart is to the body—it is the core of the car. Transmission: The car's transmission is divided into automatic transmission and manual transmission, with most cars now using automatic transmission. Most people evaluate the quality of a transmission based on comfort. The smoothness of gear shifts and the speed of shifting are important criteria for evaluating a transmission. The transmission converts and transmits the power output from the engine to the wheels, a process that involves some power loss. An excellent transmission will reduce this loss, thereby improving transmission efficiency. The speed of shifting and the smoothness of gear changes are important aspects of transmission comfort. Consumer preferences to some extent determine the quality of a transmission.
I've been in the automotive industry for quite some time, and the term 'three major components' of domestic cars is really common—it refers to the three core parts: the engine, chassis, and transmission. The engine, needless to say, is the power source of the entire vehicle, driving it forward like a heart. The chassis, which includes the suspension and braking systems, determines driving stability and comfort—it’s what keeps the ride smooth over bumpy roads. The transmission handles gear shifting, and whether it’s manual or automatic, smooth operation depends on it. Domestic brands like Geely and Great Wall have made significant progress in these areas, with some engines now being independently developed, performing just as well as imported ones. The key takeaway is to pay special attention to the condition of these three components when buying a used domestic car—high mileage can lead to issues, though replacement parts aren’t too expensive. Regular maintenance at authorized service centers can extend their lifespan. I personally think this is essential knowledge for new drivers.
