| Speedo Accuracy How accurate is the speedo on the Fiat 500? Has anyone checked it against a reliable clock or GPS? In the old days, "Autocar" used to publish figures for accuracy in their road tests, but I don't see them anymore. John

| Cinq Sp | Re: Speedo Accuracy Providing you're travelling on a flat road in a straight direction, GPS speed is far more accurate than you'll ever need.

| Re: Speedo Accuracy Right. So as we might expect, the 500 speedo is a little bit optimistic. That's fine - better than the other way around. John

The US based GPS system is not as accurate as they would like us to believe. The Galileo (European) navigation system will be far more precise if the US, who don't like it, allow it to get off the ground.
