There have been numerous reports on the ActiveE forums about the speedometer of the ActiveE (and other German vehicles for that matter) as being grossly overstated.
I wanted to see this for myself, so to test this, I went ahead and installed my portable GPS in the ActiveE and compared the velocity that it showed on the GPS with the speedometer of my ActiveE.
So, the first test was to do this on surface street speeds.
As you can see from the video, there is a discrepancy at lower speeds. So, I figured to try this on the freeway…
It looks like the folks on the BMW ActiveE forums were right. The car does overstate its speed to the tune of 3-5 mph.
