The speedometer in the Ford Xb gt Falcon 1973 in the speed unit part on the panel is correct (it is in km/h even), but there is a bug in the measurement of the same that does not exceed 140km/h on the panel, with the car above that, even above 200km/h it registers on the speedometer of the panel in the internal only up to 140.
Was there any confusion when applying the metric speed unit measure to miles per hour? For the maximum speed on the speedometer considering the margin for more, gives the 140 but in miles per hour. The car dashboard has unit in km/h.
