Afternoon all
Recently I was playing with my handheld GPS to see how accurate the Ibiza's speedo was.
The speedo in my last car, a Rover 220SDi, over-read by 10% - IE if the speedo says 70, it was really only doing about 63. I checked on various occasions and always got the 10% error. (Unfortunately it said it had done 10% more miles than it really had, too !)
I tried the same test in the Ibiza, and the speedo is absolutely bang on.
So now when I drive past speed cameras etc I have to take the speedo as being true, without driving to the 10% safety margin I always used to have !
I think a lot of cars must over-read by a fair margin, as when in the Ibiza, it seems many people drive a few mph slower than the limit, not realising their speedos are lying to them. In the Rover it always seemed that people were at the limit.
Anyone else ever tried testing their speedo ?
