Instructions!

"CTRL + f" and type in the acronym or a word.

If the definition is not provided, leave a post requesting it and someone in the CR community will come to your aid! XD (maybe HAHA)


Basically all you have to do is post the things you believe are "international" meanings of some automobile part.

If parts or devices or processes are used by a specific car manufacturer then please state the manufacturer before you put the definition in place.

The reason why I'm doing this is because there's a lot of mechanical jargon in this car section, and to tell you the truth, I don't know what many of them mean, I have to actually google the meaning, even though it comes unsuccessful at times.

Every time you post a new definition, I will update this post with your definition in it.

>>>>Don't make duplicates... it's a drag to look through every acronym..<<<<

_________________________________________________
Layout acronyms (i.e. FR, MR, FF, etc) have a formula:

"The first letter represents where the engine is mounted. "F" means the engine is mounted in the front. (Most cars are front-engined). "M" means the engine is mounted in between the front and rear axles/wheelbases. (many sports cars/exotics use this) "R" means the engine is mounted behind the rear axle/wheelbase. (1st gen VW Beetles and many Porsches use this).

The second letter represents where the engine torque is sent to. "R" means it's RWD, meaning, the rear wheels move the car. An "F" means it's FWD, meaning, the front wheels move the car. Some consider "A" a legitimate letter, which is AWD, meaning, that all the wheels (usually 4) move the car. But some do not believe the "A" qualifies.

And some FR cars are actually "FMR" cars. This means even though visually the engine is in the front and in front of the driver, technically, the engine is mounted between the front and rear axles. Notice how the following engines are mounted behind the front wheels:
Honda S2000 (F20C engine code, not sure if it's an F22C)"

"AWD's are usually based off of FWD drivetrains. Simply put, they're transaxles with a rear driveshaft. But some AWD systems are RWD based and do have a transfer case.

Subaru has what they call "symmetrical AWD", which means there is no transfer case to send the engine torque to the rear wheels. Or at least I think... BTW, Subaru's DCCD is an adjustable AWD system."

Oh man...aha this is a pretty nifty idea. But getting into specific names by different makes is gonna get super confusing.

I'll help out.
