CAB – Cabriolet

This term originally meant a lightweight vehicle with two wheels that was pulled by one horse; “cab” and “taxi cab” are shortened forms of the word cabriolet. Today, a cabriolet or CAB is an automobile with a folding top or a convertible coupe.

CABRIO – Cabriolet

A cabriolet is basically a type of convertible automobile that can convert from an open mode to an roof mode. The roof may either function manually or may function automatically with the use of either hydraulic or electrical actuators. A cabriolet is a general term for a convertible with a soft top and two doors. Since cabriolets were frequently used as carriages for hire, the name came to be shortened to the more common word, cab.

CAT – Catalytic Converter

This term refers to a device that is integrated in the exhaust system of a motorized vehicle. A catalytic converter uses a platinum or palladium catalyst to turn pollutants and carbon monoxide into carbon dioxide and water. The purpose of the converter is to reduce the harmfulness and toxicity of emissions from the engine exhaust; therefore, a converter is an important air pollution emission control device to reduce levels of exhaust gases in a motor vehicle.

CC – Cruise Control. See also ACC

Cruise control is a device that is electronic and it can be turned on to keep a specified constant speed. This can be called autocruise or speed control and it is a system that can automatically control the speed of a motorized vehicle depending on what speed the driver has set it on. The driver does not have to hit the accelerator or the brake when cruise control is set.

CCM – ccm or cm3, cubic centimetres

Cubic centimetre is a metric unit of measurement for volume that is abbreviated as “cm3” in the metric system and “ccm,” or “cc” in areas not using the metric system. It is defined in terms of a cube with its sides being one centimeter long. In the automotive industry, “cc” correlates to the total volume of the engine displacement in cubic centimetres.


Colour coded – This term refers to when the bumper of a motorized vehicle and the mirrors are the same colour as the bodywork of the vehicle.

C/CON – Cruise control. See also CC & ACC

This is an electronic device that allows the driver to set a speed on a motor vehicle that will remain constant until the cruise control is switched off. Also called auto cruise, this speed control system lets the driver keep moving the vehicle at a constant speed without the use of an accelerator or a brake. This system works by taking over the throttle of the motor vehicle to sustain a constant set speed.

C/L – Central locking

This term refers to the electric locking of doors on a motor vehicle. A central locking system lets the driver or the passenger in the front seat of the car or truck lock and unlock all of the doors of the vehicle by pressing a button; therefore, all of the locks on the doors can be either locked or unlocked at the same time by one single person.

CO2 – Carbon dioxide

This is a chemical compound that is made up of two atoms of oxygen that are bound to one single atom of carbon. Carbon dioxide is a thick, colorless, odorless gas that is made by burning carbon and compounds that are organic as well as by respiration and fermentation. This greenhouse gas occurs naturally to be absorbed by plants through the process of photosynthesis.

CONV – Convertible

This term refers to something that has the ability to change into another form. A convertible is a kind of motor vehicle that has a folding roof that can retract; this allows the vehicle to be converted from an enclosed roof into an open-air vehicle. Many different cars are offered in convertible form with a detachable or a folding roof.

CPE – Coupe

A coupe is a motor vehicle with a roof that is fixed and has two doors with front seats and a compartment for holding luggage. It is an enclosed bodied car style that includes several varieties: Club coupe, Business coupe, Opera coupe, sports coupe, four-door coupe, Quad coupe, and Combi coupe. The Society of Automotive Engines (SAE) differentiates a sedan from a coupe by the interior volume which must be less than thirty-three cubic feet of rear volume.

CPU – Central processing unit

This term refers to the hardware inside of a computer system where different operations are executed, possessed and maintained. The central processing unit is a part of a computer that controls the entire system by carrying out the computer program’s instructions. This can be abbreviated to “processor” because it processes and interprets the messages and data for the entire system.

CRS – Child restraint system

A child restraint system helps to ensure the safety of children while riding in a motorized vehicle and is generally for family use. This system works though CRS and ISO-FIX anchors that are suited to the rear seats and to the floor in the rear to make for installment of a child seat that is not dependent on the vehicle’s present seatbelt system. This term refers to a device in a vehicle that is crafted to restraint and properly position children who weigh fifty pounds or fewer to secure safely while the vehicle is in motion.

CVT – Continuously variable transmission

This term refers to an automatic transmission that can shift through an infinite amount of gear ratios that range between minimum and maximum values. The way a continuously variable transmission works is through the operation of a pulley system that can change through an infinite number of driving gears between the highest and lowest ratios available. A continuously variable transmission alters the ration of the transmission without the use of a clutch pedal, because it allows torque to be transmitted in a continuous flow from the engine to the wheels that are driving.
