But honestly, all of them have FF Drv.Tr.s so I don't think we can lose.
I actually know the answer to what these mean! I learned it reading the master, Hokudaiji Aritomeno's column in Holiday Auto Magazine. It's referring to the Drive Train of the car.
FF refers to a front engined, front wheel drive car.
Or in Hoku's sage words:
:
The engine is running. I’ll take care of the whole thing. The official name is FF. Does not have a propeller shaft. So you can expand your connections.
FR refers to front engined, rear wheel drive car.
Or, as Hoku would put it:
:
FR is when the engine is located in front of the driver and drives the vehicle. It has been around for a long time, so it is technically perfect and the driving experience is great.
MR refers to mid-engined, rear wheel drive, aka gods combination as it's what most MR2's and Ferrari's use.
But don't take my words, just ask Hoku:
:
A vehicle with the engine located just behind the drivers seat is called an MRX. Often used in sports cars. The connection is narrow.
