I do the same thing, S mode in town!Does it really prevent lugging? On my base model, A10, geared for economy, I feel like in city driving it sometimes goes too far, too low rpm -- sacrificing the engine for mpg. I couldn't say the exact rpm or situation -- I rarely hammer on it -- but it's just too low and just "doesn't feel right" sometimes. Anyone else notice this? Not sure if it is technically "lugging." I prefer "S" mode in town to keep the rpms up, feels so much better, but also seems more than is necessary to prevent it from happening....
