Exterior Car Body Part Names

1. Roof And Pillars


The roof is the top part of your car responsible for protecting you and your passengers from external elements. These come in many variations, depending on your vehicle’s make and model.

Pillars are the support beams that hold up your car’s roof. They also provide a significant amount of structural rigidity for the roof, windshield, and other upper frame parts. The number of pillars your vehicle has will depend on the vehicle’s length. Additionally, vehicle designs like the hatchback will have slanted pillars.

2 Hood or Bonnet


The car hood is also known as a bonnet in some countries. This is fitted to protect the engine compartment which includes engine, battery, coolant, windscreen fluid, cooling fan, compressor, alternator, and many more.

The hood allows direct access to the engine compartment for maintenance and repair purposes. In addition, it also protects these parts from direct sunlight and dust. A hidden latch is commonly used along with the hood to hold it securely when you’re taking a look inside your car.

3 Front And Rear Bumper


The bumper is an exterior part of your car attached to the front and rear ends. The function of the front bumper is to protect your car if a sudden collision happens. In this case, it absorbs most of the impact during low-speed collisions to prevent serious damage to the driver, vehicle, and passengers.

4 Bumper Grille

The bumper grille covers the front body of the vehicle and allows your engine to keep cool. When you drive your car, it sucks the air through the grille which serves to provide ventilation through the engine bay.

Primarily, it protects the radiator and allows cold air to enter the radiator of the car. In addition to the front location, they are also located in the front wheels for brake cooling, in the cowl for cabin ventilation, or on the rear trunk lid in rear-engine vehicles.


5 Trunk or Decklids


The trunk lid (also known as dickey) of a car is the main storage or luggage compartment which is often located at the rear of the vehicle such as sedan, coupe, or convertible.

The trunk of a car is more than just storage and must be used for the actual purpose of carrying goods. It is an important storage space, so it is necessary to clean it regularly. Also, keep in mind that if you are loading more luggage then the engine will consume more fuel.

Or We can say

The trunk is the part of your car that allows you to store the belongings you carry with you, such as bags and luggage. All trunks come with a cover known as a lid, responsible for granting and denying people access.

In most cases, the trunk is located at the back of your vehicle. However, in cases where the engine is placed at the back, manufacturers will position the trunk at the front. Alternatively, in vehicle models that have the engine set in the middle, you will find trunks in the front and rear sides of the car.

6. Tires and Wheels

Tires are the ring-shaped parts of a car that act as the primary contact point of your vehicle and the terrain. Generally made from rubber, tires consist of a body and a tread layer. The body provides the necessary support, while the tread is a set of patterns responsible for giving the tire traction.

Found in the wheel cylinders, your vehicle’s wheels are the rims that hold the tire in place and often come in various sizes and styles.


7. Windshield


The windshield or windscreen is the glass at the front of the vehicle that allows you and your front-seat passenger to see the road. Its primary purpose is to protect you from external elements and the wind your car creates while moving forward at high speeds.

While it was initially made of a simple piece of glass, modern windshields are made using laminated safety glass to prevent broken pieces of glass from harming the vehicle’s occupants.

8. Doors And Windows


As far as car exterior parts go, doors and windows are straightforward. The doors are the parts of your vehicle that you open to get in and out of your car. They are also responsible for keeping you safe while driving.

Car doors have different parts, such as the door lock, panel, handle, and storage compartment. Your vehicle could have anywhere between two to four doors, depending on its model. Also, while you can open most doors manually, it is not uncommon to have car doors that you can control from a distance.

Doors also serve as mounts for the windows, responsible for protecting you against external elements. However, unlike the windshield, you can roll these windows up and down using the window glass controller that you will find in the door.

9. Head And Tail Lights


Also referred to as a headlamp, the headlight is positioned at the front of your car and is responsible for providing you with visibility when driving at night. You can set your headlights to different modes, each producing varying types of light, including full-beam light, fog light, dipped light, and more.

Taillights, also called tail lamps, are the cluster of lights found at the rear of your car. They make your vehicle visible to the motorists behind. For instance, brake lights notify other drivers that you are slowing down or coming to a complete stop. Doing so helps you prevent other vehicles from hitting your car from behind.

There are currently several types of head and tail lights, including halogens, laser, HIDs, and LEDs. However, LEDs are more popular because of their energy efficiency. On top of that, they are also brighter than most other types of bulbs.

10. Signal Lights

Signal lights are a collection of lights found at the front and rear of your car that blinks when switched on. They are responsible for informing other motorists of the direction you intend to head towards. Usually, the controls for signal lights are found on the left of your steering wheel column if you have a right-hand drive vehicle.

Modern vehicles have front and rear signal lights and hazard lights that function by blinking all signal lights simultaneously to make your vehicle more visible.

11 Wiper Blade

Almost all vehicles including cars, trucks, buses, etc. have wiper blades and are very important for the clear vision of the driver. These are used to clear snow, water, and/or debris from the vehicle’s front window so that the operator can see what lies ahead of them.


12 Cowl Panel


Cowl panels are also important car body parts. These are used as a cover that fills the gap between the hood and windshield of the car. It also supports the dashboard and ensures that no unwanted parts get into the windshield wiper system or the cabin filter area.

13 Quarter Panel


It is a side section of an automobile body that usually wraps around the wheel well, between the door and trunk lid, or between the door and the hood. It supports the back panel and other rear panels which may include the trunk of the car, as well as the rear fenders/bumpers.

14 Fender


The fender is the curved part of the car’s body that sits on top of the wheels and holds them in place. It is not only a safety component but also enhances the overall look of your vehicle. Its primary function is to shield and protect the passenger compartments by preventing sand, mud, rocks, liquids, and other roads spray from being thrown into the air by the rotating tire.

15 Fender Liner

In every type of vehicle, each wheel has a separate fender liner. The function of fender liners is to prevent dirt, mud, water, environmental toxins, and other impurities from seeping into the engine bay causing serious damage.

In addition, it also helps to protect the wires and other components inside the wheel well from corrosion. Driving a vehicle without a fender liner is not recommended as it acts as both a buffer and a barrier between your car’s engine, hood, radiator, headlights, and windshield.


16 Sunroof

The sunroof gives passengers a clear view of the sky, keeps the car ventilated, and lets the sunlight in, creating a feeling of open space. This is a type of panel on the roof of a car that either slides or can be pulled out to allow light in.


17 Mirrors

There are mainly two types of mirrors used in vehicles that are side-view mirrors and rear-view mirrors.

1. Side-View Mirror

These are also known as wing mirrors. These mirrors are located on the exterior of the vehicles to help the driver see areas behind and side of the vehicle or outside the driver’s peripheral vision.

Also, it will alert the driver about possible accidents that happen from behind. The advantage of side mirrors being convex is that you get a wider view of each side of the car which helps reduce blind spots.

2. Read-View Mirror

They serve multiple purposes that help to keep you safe as a driver. It gives you an alert driving experience by allowing you to see behind your vehicle without turning your head. In addition, they are especially important when a vehicle is moving in reverse gear.

18 Quarter Window

It is a type of side window that is located before the front door glass or after the rear door glass. In some models, the fixed quarter window may be placed in the corner or “C-pillar” of the vehicle.

They provide a quick peek of the road around the vehicle so that the driver can turn, speed up, park, or change lanes safely. These windows are often found on older vehicles. These are small triangular in shape at the front and separate from the main window.


19 Door Handle

Door handles help the driver or passengers to get in or out of the car. Door handles are the most important component as they contain door locks. Usually, we use the door handle to unlock the car from outside or inside. There are different types of door handles available according to the car model.


20 Mud Flaps

Whether you have a car, an SUV, or a truck, getting mud flaps for your vehicle is necessary. This is useful when your tires are constantly exposed to mud, dirt, rocks, salt, water, and other elements on the road.

As the name suggests, mud flaps are meant to catch dirt and stones and ensure that it doesn’t fly straight into your vehicle from back and front. A car without mud flaps will require more regular maintenance.


21 Hubcap

It is a decorative disc on an automobile wheel that covers the central part of the wheel. The function of the hubcap is to cover wheel hub and wheel fasteners to reduce the dirt and moisture collection. It also enhances the overall structure of the wheel.

When you drive without a hub cap, all kinds of dirt and debris get trapped in the tires, which can lead to tire wear and tear. By having a hubcap, foreign particles do not damage your wheels and provide longer life.


22 Dashboard

The dashboard is the controlling panel of any kind of vehicle. This is also known as dash or instrument panel. It lies within the central console of a vehicle and is usually located directly ahead of the drive.

The dashboard shows the driver tools and controls for operating the vehicle. It has simple controls (eg, steering wheel) and an array of instrumentation to show speed, fuel level, and oil pressure. Modern types usually feature information, climate control, and entertainment systems.


23 Number Plate

Due to the Motor Vehicle Act of the government, it is necessary to have a number plate on every vehicle. The number plate reflects the very specific details of the vehicle and consists of four important elements.

It also gives a unique identity to the vehicle. Nowadays, all vehicles on the road are preferred to display registration on both the front and rear sides of the vehicle.


So this are the car body parts names. which every one has known who drives the car.
