A dragster is made of tubing and is called "pipe"......as in "got new pipe" or it's a "pipe rack".

Motor, engine, powerplant, mill, churn, heart...........whatever you choose to call it.....all mean the same and everybody KNOWS what you mean.

And if we want to get literal about the definition of a "motor".....oscaracme should actually look it up before he goes tossing around definitions of what is and isn't right. The definition is something that imparts "motion".......that can be electrically or mechanically driven motion.

Then of course there are the spin offs........such as "Motorsports", driving on the "Motorway" and the list goes on
