I will when I get back. Of course. I had a 2000 Explorer that read 120 and I buried the needle. So It is really up to the maker on what they want to put. Do you want to buy a Ferrari that says 80 or 185 on the speedometer. So it doesn't mean it is 100% of that engine.
Governor (device)
If it is up to the maker, the maker should place the speed they limit the engine to and only that speed as the maximum number on the speedometer or at least place this info in the owner manuals or specs materials so that the buyer can make a 'fully informed' choice.
Imagine if you were in a life or death situation and you find out later that you could have gotten to a hospital faster by taking another vehicle. I think that anyone in such a situation would choose the vehicle that goes faster. I've been in that situation and I was pretty upset about it. Not everyone has a choice of cars to rush to the hosptial in....but I would have chose my Jeep instead of my G6 that day...if I had known.
Automobiles are a common application, and modern automobiles are equipped with such a mechanism for various reasons. There are two types of automobile governors, one limiting the rotational speed of the engine, the other limiting the speed of the vehicle. In small, low power applications, governors are used to protect the engine from damage due to excessive rotational speed, or pushing the engine past its peak abilities. In larger, higher performance engines governors are used to limit the vehicle speed. Many performance cars are limited to a speed of 250 km/h (155 mph)[2] to limit insurance costs of the vehicle and reduce the risk of tires (tyres) failing.
