Most manufacturers deliberately knock the speedos out, all VAG cars are out on the instrument cluster but the can bus speed is accurate that the ECU uses.
You can calibrate this out by changing a setting with Vagcom/VCDS. I did this and the speedo exactly matches GPS up to 100 ish then it is out around 1mph. I suspect Audi changed this setting on the TT-RS press car that Evo has as they commented on its top speed run that the speedo was only 2mph out at 169mph.
