Glossary of Car Acronyms – Decoding Car Abbreviations

What are the most important car acronyms and abbreviations to know?

Don’t you find it frustrating when you need to discuss a computer issue with an IT specialist and they talk about the restrictions of your field servoid from your mongolian hordes technical department in cybercrud that leaves your own mental bandwidth feeling like you need to reboot? Those in-the-know understand, but you wouldn’t be standing there with your problem if you yourself were in-the-know, would you? The same goes for cyclists about cycling, horse-lovers about anything equestrian and even dancers about ballet combinations!

Us car folk can get carried away with ourselves too. As with all enthusiasts, it comes from a love and eagerness for what we do, that sometimes our own car acronyms and abbreviations make perfect sense to our own in-the-know ilk, but might be alienating to those outside. Let’s break down some of the most common vehicle acronyms with our own car abbreviations list and help make our Subaru-love a little more inclusive!

 

Car Terminologies

What does ABS stand for?

ABS:     Anti-lock Braking System, designed to prevent the wheels from locking up and skidding under
hard braking

 

AC:       Air Conditioner

 

ACC:     Adaptive Cruise Control (check out our feature on this for more information)

 

AEB:     Autonomous emergency braking, designed to detect objects in front of the car and will apply
the brakes in order to prevent an imminent collision

A/T:     Automatic transmission; when a gearbox shifts automatically. This can range from torque
converter, CVT, dual-clutch and automated manual.

AUX:     Auxiliary. Normally refers to an auxiliary audio connection such as a jack that allows you to
connect phones and music players directly to the car’s audio system.

AWD:    All-wheel-drive, where power is fed to all four wheels of the car. Can be permanent AWD
(power is always fed to all four wheels) or switchable (power is fed to two wheels unless it
detects slip, then it pushes drive to the other two).

BHP:     Brake horsepower which is the standard measure of the power an engine puts out which
affects top speed and acceleration.

CC:       Depending on context, this can refer to cruise control, climate control or even cubic capacity
(the size of the engine, measured in cubic centimetres or litres, for example 999cc or
1.0-litres).

CEL:     Check engine light. A warning light on the dash that signifies an issue with the engine which
should be checked at your earliest convenience.

CO:       Carbon monoxide. A harmful engine exhaust emission.

CO2:     Carbon dioxide. One of the main gasses emitted from a car’s exhaust.

CVT:     Continuously Variable Transmission. A form of automatic gearbox characterised by having one
automatically varying gear ratio, rather than a number of fixed ones.

DAB:     Digital Audio Broadcasting (often referred to as Digital Radio).

Diesel:  Different manufacturers use a baffling array of codes to signify engine types.

DFI/DGI:Direct fuel injection/direct gasoline injection.

DRL:     Daytime running lights. Also called driving lights, these front lights operate whenever the
engine is on. Manufacturers often use them to create a stylish front to the car.

EBC —   Electronic brake control.

EBD —   Electronic brake force distribution which varies the amount of braking force applied to each
of a vehicle’s wheels to maximise stopping power (always coupled with ABS).

ECU —   Electronic Control Unit or Engine Control Unit. This takes readings from a variety of sensors
within the engine and adjusts the likes of air-fuel mixture, ignition timing and idle speed to
ensure optimum running.

EPS —   Electric power steering, an efficient power-assist system than the hydraulic systems used in
older cars.

ESC —   Electronic stability control which automatically applies the brakes when it detects a loss of
traction to prevent a skid. This is sometimes also called ESP (electronic stability program).

EV —     Electric vehicle. A vehicle which is powered primarily by an electric motor.

bulbs due to a superior lifespan and improved light.

LEV —   Low emissions vehicle.

LSD —   Limited slip differential which prevents excessive power from going to one of the driven
wheels to avoid pointless wheelspin.

LWB — Long wheelbase which is in the context of a car with a stretched wheelbase (normally
