Cruise Speed Indication vs Speedometer

msimon18 · 06-19-2007, 07:31 PM

Another item I have noticed after a little more time in the car. When I set the cruise control at a given speed the little bar moves up about 3 - 4 miles an hour ABOVE where the speedometer is registering and stays there unless I change the speed setting. Regardless of where it is it is always OVER the actual speed ?

Anyone seeing this ?? Could it be related to the thread on Speedometer Accuracy ???

Assuming there's nobody ahead of me (Active Cruise), the needle sits right on the dot.

My needle and digital read-out agree with each other. On the other hand, neither agrees with my GPS.

Mine reads high also - about 2-3MPH

Don't really care too much if it compares with the GPS (my wife's Lexus does not either), but I do think the indicators should match and align with each other !! Back to the dealership !!

It's normal for it to show a bit high.

Mine seems to be spot on, no deviations. I hate it when my saab goes down hill, it jumps by 3-4 mph, which is just enough to take me over the "ticket" speed.

Has been discussed before. It's normal and there is some variation from car to car. Some cars, it's much worse than just a couple mph. FWIW, my cruise indication is about 1 mph higher than the speedo.
