question about the speedo
 

hey everyone..

i was looking at my speedo on my w126 300SD and realized that 55mph was much different than the other numbers on the dial..any reason? has it to do with the highway speed back in the day? or isnt it that speed that the car is most efficient?

just wondering

that was during the time 55 was the national speed limit, see document at link below and scroll down to popular culture
