Hi there Mr K
Here's a link to a site with specs for the FL S8, where they reckon 0-60 of 6.3.

I have a cheapo VAG-COM link & software It plugs into my laptop. You then find a nice straight, flat (and legal) place. Park, snick your motor into gear, press the appropriate button on your lap top, then go for it.
The software records your 0-60, 0-100, standing 1/4 mile and terminal velocity. As simple as that.
OK in case you're wondering what the stats for mine (02 S8) are, I don't have em.
Tried it out last year when I got the lead, but haven't yet had a serious go at it.
I have a set of these leads and software to sell, if I'm permitted to say so here.
