VW figures are no doubt conservative but it is not that far off from magazines figures! Remember the quoted 6.9 seconds is 0-100km/h or 0-62.5mph not 0-60mph. That extra 2.5mph can take up to 0.2-0.5 second to achieve!
Also performance figures are taken with a driver (75kg) and a full tank of fuel on a standard car. If you got a five door, heated seat, big alloys or overweight, your car will be slower!
That's why I like BMW, Porsche and VW. You can always beat the official figures!
Not even Stig can match official figures from Audi, Ferrari and Ford!
Eg. Audi A5 2.0 0-100km/h in 6.6 No way!
