SC - Supercharged

MR2 - Mid-Engine , Rear wheel drive, 2 seater.

Yar! The technicality of it all!
I personally like to call it the "midengine rearwheeldrive 2seater"

But yeah, TECHNICALLY, the "R" stands for Runabout. It just doesn't sound cool enough though! *sigh*

Another example is SR-5, which stands for Sport Runabout-5speed

Somebody forgot to add "AFR" to the list of acronyms!

AFR: air/fuel ratio

O2S: oxygen sensor
HO2S: heated oxygen sensor
CR: compression ratio
P&P: port and polish
CAI: cold air intake
i/h/e: intake, headers and exhaust upgrade
dizzy: distributor
ICM: ignition control module

Not in the MR2 world. Check my screen name. I used to have a 1993 steel mist gray turbo. Hence the SMG.

The MKIII had SMG/SMT (sequential manual gearbox/transmission)
