Names of Exterior Car Body Parts

Wheels and Tires

The ring-shaped components of an automobile known as tires serve as the main point of contact between your car and the ground. Tires typically have a body comprised of rubber and a tread layer. The body gives the tire the support it needs, and the tread’s network of patterns gives it traction.

Your car’s wheels, which are the rims that hold the tire in place and are often available in a variety of sizes and designs, are located in the wheel cylinders.

The windows that shield you from the outdoors also act as mounts for the doors. The window glass controller is located in the door, and unlike the windshield, it allows you to raise and lower these windows.


The glass in the front of the car that gives you and the person in the front seat visibility of the road is called the windshield or windscreen. Its main objective is to shield you from the elements and the wind that your fast-moving car produces.

The group of lights at the back of your car, often known as the taillights or tail lamps, are called taillights. They increase the visibility of your car to oncoming drivers. Brake lights, for instance, alert other vehicles when you are slowing down or stopping entirely. By doing this, you can avoid having cars rear-end your vehicle.

Head and tail lights today come in a variety of styles, including halogen, laser, HID, and LED. However, due to their energy effectiveness, LEDs are more widely used. Additionally, they are brighter than the majority of other types of bulbs.

Signal Lights

Names of Interior Car Body Parts



Your car’s engine is regarded as its heart. By transferring the heat from burning gas, it generates the force required to turn your vehicle’s wheels and move them ahead.

Although it seems straightforward, the duty the engine completes is actually rather complicated. It must has sufficient strength to support the enormous weight. Fortunately, there are many various kinds of engines, and each one has a unique structure that affects how effectively they operate. Drivers also have the choice to further alter the performance of their engine.


Your car’s alternator is a crucial component. The alternator is the main portion responsible for powering the car’s electrical components, despite the fact that most people attribute this duty to the battery.

Since your vehicle’s engine is where it draws its mechanical power from, alternators are frequently mounted in front of or next to the engine. They are in charge of producing the electricity needed to keep the engine running and charge the battery. Additionally, it provides several car components with this electrical power.


Another essential component for keeping your car running is its battery, which enables all of its electrical parts to work properly. Batteries were useless in the past because most automotive parts were manual. However, they are now essential thanks to current technology.

The structure of modern batteries is not particularly intricate. Most are just six-cell wet cell batteries. But there are different battery types, and each one has advantages of its own.


Your vehicle’s efficiency is greatly enhanced by the radiator, which is in charge of keeping your engine cool while it is running. Overheating brought on by a broken radiator might harm the engine.

The transmission cooler, core, pressure cap, intake tank, and outflow tank are all crucial components of the radiator. By absorbing the heat from the liquid and gas that enter the engine, these components help to keep the engine cool. The vehicle’s radiator disperses the heat it absorbs outside.


The muffler, which is a component of your car’s exhaust system and is located at the bottom of the vehicle at the rear, helps to quiet the engine and dampen pollutants.

Although its operation is simple, the science underlying it can be somewhat complicated. Burnt gases are released into the exhaust system when the exhaust valve opens. The muffler muffles the loud sound wave produced by these burned gases before releasing it outside.

The majority of mufflers are frequently constructed from steel with an aluminum coating, giving them the strength to withstand extreme heat.

Converter Catalytic

Your car’s exhaust gas contains nitrogen dioxide, carbon monoxide, hydrocarbons, and nitric oxide as a result of the engine operation. These emissions are converted into water vapor and carbon dioxide by the catalytic converter using chemical reactions.


The term “transmission” describes the gearbox of your car. The complete drive train, comprising the clutch, gearbox, prop shaft, differential, and final drive shaft, is referred to by some as the transmission.

The transmission uses gears and gear trains to assist you in changing your speed and torque. Depending on the speed fluctuation, you can select between a few gear ratios that are included.

Additionally, whereas manual gearshifting was required in earlier car models, an increasing number of cars today have automated gearboxes.


Your car’s axle is a shaft that you can find there. It keeps the wheels attached, allowing them to turn freely. The component aids in carrying your vehicle’s weight.

The front axle, rear axle, and stub axle are the three main categories of axles. The rear axle connects the back wheels, whereas the front axle keeps the front wheel of your car together. The stub axle is in charge of attaching the wheels to the central axle.

The size of your car determines how many axles it has. The front axle, however, is often in charge of responding to steering wheel movements.

Fuel tank

The place where the fuel that makes your car operate is kept is called the fuel tank. Fuel is inserted into the aperture that fuel tanks have. They also have a hole via which fuel is directed toward the engine.

Depending on the size of your car, the tank’s size will change. For instance, compared to other cars, compact cars have smaller gasoline tanks. Fuel tanks are often constructed utilizing a variety of materials to prevent contamination of the fuel. Additionally preventing the fuel from oxidation, doing renders the tanks rustproof.

Center Console

The transmission tunnel, which is located between the centerline of your car, is positioned on top of the center console. It is also the location of the gear shifter’s default position and the start of the dashboard. 

Depending on the brand and type of the car, center consoles might differ significantly. While some center consoles contain storage compartments and cup holders, others operate the onboard entertainment system and comfort equipment.
