Re: 16V Scirocco top speed

For more exacting comments on the speedo error of
various VW's, find the original R&T road test for your
vehicle. They always included indicated vs actual
speed data (usually at 60 mph)

Like most mfgrs, VW speedos are a little optimistic.
10% as indicated below seems a bit high though.
