Automotive Glossary

ABS (Antilock Braking System)

It is a system to avoid lock during braking. Due to this, the driver will no longer be able to loose control of the wheel in slippery areas. The system acts directly on each wheel and hence brakes can be adjusted, thereby avoiding skid motion of a vehicle.


Adaptive Cruise Control (ACC)

Cruise control that adapts to varying speeds of other road users and adjusts the distance between vehicles.



It is an equipment fitted within vehicles, usually as a nylon bag that is designed to protect both the driver and passengers in case of an accident. In the impact, the airbag sensor activates and inflates instantly. It acts as a major precaution besides seatbelt.


All Wheel Drive

A traction system in which all four wheels are driven by the engine. AWD systems are superior four-wheel drive systems because they can be used efficiently regardless of road conditions. AWD systems use a center differential that allows the front wheels and the rear to spin at different speeds.



It is a device that transfers power from the gearbox to the wheels. It consists of plates impregnated with a friction material, which are designed to transfer power from the engine to axle rotors. It is also used to change gear and control speed.



A component that provides power to all electrical systems in a vehicle.



A Unit used to measure the effective power of a vehicle. One horsepower is equal to 736 W.



It is usually a big box-shaped car, designed to carry goods. It is equipped with cabin and fixed platform.


Cubic capacity

It represents the displaced volume of pistons in an internal combustion engine. It is expressed in cm³ or liters.



An element of an internal combustion engine with electric ignition, which serves to atomize the fuel and air and introduce them to the motor in a controlled rate.



A component of a motor vehicle, designed to transport people and goods. It is placed above the axles and wheels.



It is an element of exhaust system, which aims to reduce air pollution by re-burning gas. It consists of a steel casing made of ceramic or metallic support to be submitted with catalytic substances.



A unit of measuring resistance towards gasoline detonation(premature ignition). The higher the octane,  the smaller is the chance of detonation.



National road, reserved exclusively for motor vehicles, equipped with two one-way streets. It has at least two emergency lanes in each direction, separated by a median area in both ways. Entry and exit are limited, allowed only at essential places.



Motor based machine with the purpose of travel and transportation on public roads.



A longitudinal subdivision of roadway, bordered by road markings.


Direct Injection (DI)

Fuel is injected directly into the combustion chambers and burned well in order to deliver high efficiency and output.


Electronic Stability Program (ESP)

It is a system that is designed to keep vehicle on the road if it tries to skid or lose road due to hard turning or braking.


Head-up Display

It displays necessary information on windshield of a vehicle like speed, weather, engine health etc.



An instrument mounted on vehicles, designed to measure the distance traveled from the manufacturing date of an automobile.



It can be defined as, how well a car can be steered. It refers to the quality of control while the vehicle is in motion.



Shaft ends having two spindles which are mounted on wheels of a vehicle.


Rear Wheel Drive (RWD)

The engine is placed at rear wheels for better overall balance. Rear-wheel drive offers superior maneuverability and acceleration as compared to front-wheel drive.



A non-motor vehicle attached at the back of a car, SUV, Truck or Van that is designed to transport people, animals or goods.



A system component of a motor car that is designed to minimize effort of the driver to change direction.


Navigation system

It is a guide to assist in traffic. By typing the vehicle position and the destination, shortest or the least crowded route is displayed. It works via satellite.


Traction Control System (TCS)

The system prevents wheel spin and enhance vehicle stability of the road.



A system through which engine power is transmitted to the wheels.


Electric Vehicle

A vehicle which uses as an energy source exclusively from electric or hybrid systems.



A component of a motor vehicle that is located in the engine cylinder which contains a conducting fluid under pressure.



A modern day caravan, usually like a mini-bus which is used to transport heavy goods.



A system made of springs, shock absorbers, torsion bars, fittings, arms, etc. The purpose is to alleviate(reduce) shock caused by road bumps.
