Just had a little good spirited tussel with a silver S5. Now, i'm not sure if it was the 4.2 V8 or the 3.0 supercharged one. Had a private plate, C12 *** I think. Anyway, it was in front of me at some lights in an industrial estate. He gunned it off the line and I took a second to react then gunned it too, but fluffed a gear change. Never-the-less it didn't pull away much. He slowed due to traffic ahead then gunned it again as did I, and again he couldn't pull a decent gap. Yes, he was a little quicker but not as much as I would've thought. He kept going to license-losing speeds (I backed off) and came up behind a van at which point he decided to take a shortcut to try to get ahead of the van, rather than wait for a safe overtaking opportunity. He ended up behind me and the van, haha. I guess he only has 80 - 100bhp and about 20lb/ft more than me, and a weight disadvantage (?). I bet he was a little miffed that he couldn't shake a 52 plate S3 though! Having said all that, I did get beaten off the line by a Merc CDi Estate yesterday (side by side at the lights, in to a single carriageway about 30 yards ahead)- but only 'cos I wasn't expecting him to put up a fight and he nosed ahead before my turbo spooled! Haha. Anyway, that is all.
