alt Hacker NewsProbably made worse by the fact that _every_ VW brand car I’ve driven has read about 10% high on the speedometer. I think I’m going 100 kph, but timing using the km markers on the highway show I’m going about 90.
When I talked to the dealers, they said that the speedometers only have to be accurate +/- 10% according to the SAE specifications.
After DieselGate I assumed that the high reading was to game the fuel consumption game.
Never again, VW auto group…

I have a GTI and with cruise control on, the speedo and my phone's gps reads exactly the same speed.

Just use the speed reported by your GPS. Most navigation apps show the GPS-based speed.

I believe the requirement is only one way - they can read high by a certain % but they cannot read low. Which makes sense. But that means in reality they will usually read a little high.
