A-pillar: The vertical roof support between the windshield and front extremity of front side window of a car.

Air Dam: A front spoiler that is installed below the bumper and designed to reduce airflow under the vehicle.

Alloy wheels: Alloy wheels are made of a mix of metals. Alloy wheels generally improve the appearance of the vehicle and serve as a replacement for normal car wheels.

Anti-Lock-Braking System: It is a braking system, which automatically reduces braking forces when it detects any of the wheels have locked up, or are in the verge of locking.

Anti-Roll Bar: It is a bar, which acts as a suspension element and improves vehicle handling by increasing stability during sudden shakedowns.

It acts as a suspension element that reduces body roll by resisting any unbalanced vertical motion between wheels with which it is connected to.

Air Bags: An air bag is a flexible membrane or covering that is inflatable and contain air or some other gas. They are usually placed on both driver and passenger sides. They are safety devices and are said to reduce the death risk by about 30% in head on collisions. If a vehicle collides with something, the air bag can inflate in less than tenth of a second and protect passengers from forces of the head-on collision.
The use of seat and shoulder belts will maximize the effectiveness of air bags.

Air Brake: They are usually installed in heavy-duty trucks, which use compressed air for their operation.

B-Pillar: It is a vertical metal roof support between a vehicle's front and rear side window.

Body Style:Refers to the external shape or design of a vehicle.

Brake Drum: It is the large circular surface that is pressed against by the brake shoe to stop the vehicle.

Brake Pad: Used in a disc system, it is a replaceable piece of backing plate and additional friction lining.

C-pillar: The metal roof support between the side edge of the rear windshield (also called the backlight) and the rear edge of the rear window.

Central Locking System: Vehicles which has power door locks, all doors are locked or unlocked at one time.

Console: A console is characterized by the ability to hold various articles such as food and beverage containers, notepads, pens and other similar items, particularly in a substantial horizontal position.

This is a unit found between the front driver and passenger seat that contains the automatic transmission shifter, cupholders and a storage compartment.

Damper: It is referred to a device that reduces vibration in the vehicle.

Ding: A small depression or scratch in the body of the vehicle.

Gasket: Any thin, soft material placed between two metal surfaces to create a good seal.

Head Room: Refers to the distance from the top of an occupant's head to the headliner inside a vehicle.

Headliner: It is the interior covering of the roof of a vehicle. Headliners often contain consoles with grooves for garage-door openers and other devices, as well as dome lights and wiring for electrical and electronic components attached to the headliner.

Lift Gate: Refers to the back side opening on a hatchback.

Moonroof: A window-type opening in the roof of the car that can open or adjusted up or down.

Odometer: It is a device that indicates the number of miles a vehicle has been driven.

Oxygen Sensor: Measures the amount of oxygen in the exhaust.

Package Shelf: It is the edge between the rear seat and the backlight or rear windshield. Generally, it contains the sound systems rear speakers and, on some vehicles, the CHMSL or center brake light.

Quarter Panel: It is a sheet of metal panel that covers the front and back quarters of the vehicle.

Spoilers: Spoiler in a car consists of a styled piece of fiberglass which enhances the aerodynamics of the car. They improve braking, stability and cornering at speed by splitting up the normal aerodynamic lines of the bodywork and using the created force as the vehicle passes through the air to press the car down onto the road.

Standard: This is an equipment generally included in the base list price of an automobile.

Shift Interlock: It is a safety device in vehicles with automatic transmission that prevents the driver from shifting out of position unless the brake pedal is depressed.

Side Airbag: It is an inflatable membrane that fills the space between the door and the occupant to prevent head, torso and pelvis injuries when a vehicle is hit from the side.
