This section covers many new features such as a rearview camera, climate control, navigation system, entertainment system, ventilation control, automatic mirrors, and more. Now let’s look at the interior part of the car one by one.

Steering Wheel

At first glance, the steering wheel looks simple, but there is more to it than meets the eye. The main function of the steering wheel and the system to which it is connected is to control the direction of the car. Converts the driver’s turning command into rotational motion of the car’s front wheels. The steering system transmits the driver’s movements through various joints and hydraulic lines before they reach the rubber when they hit the road surface.


A speedometer is a device that calculates and displays the speed of a car. A fuel gauge is a device that indicates the amount of fuel remaining in the tank.

Indicator Signals for Turning

All four corners of the car are equipped with turning indicators. These signals are usually displayed on the car as green arrows pointing to the next turn. Some cars allow the turn signal lever to be located on the left side of the steering wheel. Push the stick to the right to turn right, and to the left to turn left.

Air Ventilation

Most cars are now equipped with air conditioning also known as an air conditioner. In the internal air circulation system, the air conditioner circulates the air inside the car to cool it. A fresh air approach takes outside air into the car by opening the air duct at the front of the car.

Audio System

A car audio system is an important part of the car interior that provides in-car entertainment and information to passengers. FM radio, cassette player, tape player, DVD player, GPS system, and smartphone controllers such as Car Play and Android Auto are all included.

Storage Box

A storage box is built into the dashboard of a car to store various items like License Papers, Perfumes, or others. It hangs under the passenger seat.

Accelerator Pedal

The accelerator is another name for the accelerator pedal. It’s on the right side of the floor & controls the amount of gas injected into the engine and car speed. As the car accelerates, gently depress the accelerator pedal.

Clutch Pedal

Only cars with manual transmissions have a clutch pedal. It’s on the floor to the left of the brake pedal. When the driver pushes it, the clutch closes, stopping the flow of power from the engine to the transmission.

Brake Pedal

The pedal controls the brake mechanism of modern automobiles located on the floor to the left of the accelerator pedal. When the driver hits the brakes, the brakes are applied, slowing the car to a stop.

Air Bags

An airbag is a component inside a car that uses a bag that rapidly inflates and deflates rapidly in the event of a collision. These include airbag cushions, flexible fabric bags, inflation modules and impact sensors.

Gear Knob

A gear knob refers to cars with manual or conventional transmissions. The driver manually shifts gears using the gear knob when accelerating and decelerating the car. It is installed in the center console of the car.

Power Window Knob

A power window is a car window that can be opened and closed with a button. Electric windows have replaced the typical manual steering wheel.

Hazard Light Button

Vehicle hazard warning lights are visible warning lights. The driver turns it on by pressing the hazard warning button or switch. These lights warn other drivers that you may be involved in an accident or that your car is parked on the curb. When the hazard lamps are turned on, all turn signals are turned on.

Emergency Brake Knob

The emergency brake, also known as the handbrake, is a lever located in the center console of the car that allows instant braking. It consists of a cable and traction mechanism connected to the brakes of the motorcycle.

A/C Control Knob

Car temperature is controlled by the driver’s control panel. Ventilation fans carry cool air from the air conditioning system, or warm air from the engine coolant, through ventilation openings at appropriate locations inside the car.

Beverage Holder

A cup or beverage holder is a device that can be used as a car, restaurant table, or travel cup holder. They become cars and chairs and can be wall mounted on planes, boats, buses, and trains.


Automotive interior systems include driver and front passenger seats equipped with seat belts. The driver of the car sits in the driver’s seat. The passenger seat is located on the side of the driver’s seat. Seat belts are automotive safety devices designed to keep the car safe in the event of an accident or sudden stop.

Foot Mat

Dirt from your shoes spreads all over your car, creating a foul-smelling and unsanitary environment. Floor carpeting helps prevent dust and moisture build-up in the car.


The heart of the car is the internal combustion engine. Engine blocks include parts such as timing chains, camshafts, crankshafts, spark plugs, cylinder heads, valves, and pistons.

Gear Box

A transmission is a transmission made up of gears and gear trains that make effective use of engine torque to shift gears and propel a car.


Batteries provide the power needed to power the car’s electrical components. Your car won’t run without a battery. As part of the electrical system, the alternator charges the battery and powers the electrical system while the car is running.

Steering & Front Suspension

Helps improve car drivability and handling. System designs vary, but typically include shock absorbers/struts, ball joints, tie rod ends, rack and pinion steering systems, and idlers/steering arms.

Catalytic Converter

A device that controls a car’s emissions, a catalytic converter converts harmful gases and pollutants into less harmful emissions before they exit the car’s exhaust system.

Fuel tank

The fuel tank is usually located in front of the rear axle and contains the gasoline that powers the car. Placement is important to avoid areas that can crumple on impact.

Rear Suspension

Like the front suspension, the rear suspension also contributes to the car’s handling and ride quality. Systems vary but typically consist of shock absorbers, coil springs, ball joints, wishbones, and CV joints.


The interior or every component inside a car, in addition to its appearance, is the part of the car most seen and experienced by drivers and passengers. For example, steering wheels, dashboards, seats, door panels, etc. With the right design, the car interior can be an important sales incentive and comfort factor.
