Can anyone tell me what each of the letters mean in "S4Rs"?
In general, I always thought 'S' meant 'sport', or higher performance than the base model, 'R' is for racing, not for the street. In this context, I guess why they might use both 'R' and 'S'... and I assume the '4' stands for the number of valves per cylinder... but what that lower case 's' means I don't know.
Who knows? The words could be in Italian for all I know, and since I have one, I'd like to put a name on my addiction
