A picture of a speedometer doesn't mean shit. Speedometers are not accurate. They read over at least 3% - 5%, some more. This has been discussed on this forum a thousand times. 161 on GPS indicated well over 170 on my speedo.
161 is where we are limited electronically. Mine is now removed, which has been confirmed with an indicated 165 on GPS. That was against a pretty good headwind and that's where I backed off due to losing the window seals around the doors. One downside of a coupe vs. sedan.
