Speedo
Anyone else notice the change in scale on the speedo from 5mph per unit to 10mph per unit above 60mph at 12oclock?
Be careful you might think you are doing 65
Never seen this before. Not a complaint just and observation

I didn't see that. I usually just leave the display on AMG and refer to the digital speed readout.

I got a ticket because of that, was doing 75 mph on a 50 mph when I though I was doing 65 or something. The officer was a really nice guy so he put 59 on a 50 and said he never goes to court.

I've never seen a readout change scale mid range..... It's not a gripe.... but I must say it comes at a pretty critical MPH that results in tickets in the USA if you get it wrong.
"perhaps it's a -ready-made- excuse" to get out of a ticket...... "sorry officer, those crazy germans and their changing engineering scales....." .......
They should have made the tach logrithmic to make things interesting

Could someone please post a picture of the speedometer? I'm not seeing this non-linear scale in any photos from the DOG or the sales brochure.

The more I think about this..... the guys @ AMG must have a sense of humor!
I could see the change in scale at something more innocuous like 100mph.... but NOT right in the range of the avg us speed limit!

I'd like to meet the guy in charge of this decision and see just what was he or his team thinking LOL.

That's so weird! 
The picture on the left is the speedo from the C63S MY16 Dealer Ordering Guide which shows the calibration in km/h. Note that it is completely linear! I wonder who in MBUSA had the bright idea to create the one in the ED1? I've never heard nor seen anything like that before. I could see that if it started at 80 mph, but not right in the middle of the speed limit range on most interstates! The image of the speedometer on the right is what I think that the engineers were trying to accomplish.
Update: The configurator on the MBUSA website shows the non-linear speedo in mph for the C63S so it's not an ED1 issue.
I wonder how long it will be before a design change is implemented?

It's a big difference starting at 120 vs. 60! I wonder why the designers thought they needed to change the scale at a lower point. Perhaps someone read the specifications wrong for the speedometer scale?

Yeah... Scale change at us avg speed limit is non-optimal.
I wonder what Leo interpretation of speeding laws wil be regarding confusing instrumentation.
I bet they end up changing this.

Not saying that's the right response, but it's probably a likely one.

Oh I agree re: the section I put in bold. I just wanted to mollify any concerns that this was a flaw in the speedometer design from a physical standpoint. I wasn't trying to establish a position on either side of the fence regarding whether having the interval change at 60 mph is a problem from a philosophical/practical standpoint.
It's a possibility. Benz's best response to any concerns might be: "You have access to a digital speed readout in your gauge cluster."
Not saying that's the right response, but it's probably a likely one.

Perhaps the entire speedometer could be optionally replaced by a large clock!

It's called Usability Engineering. Placing cruise control levers where other manufacturers placed the turn signals was a problem for years. If one has multiple vehicles which report the speed of travel in a substantially different manner, then there will be misinterpretted information with unintended consequences. It's too bad that the entire instrument panel is not an LCD which could be easily reconfigured.

Or did you just decide to enlighten me anyway?
Regardless, thanks for the info. 
Again, to clarify, all I was demonstrating/asserting with my photos was that interval changes on U.S.-spec AMG cars are not out of the ordinary (irrespective of where they occur).
Personally, once I know where the interval change occurs, I'm good. I have 2 other MB cars and they each have distinctive gauge clusters. If I was completely overwhelmed by the gauge setup, I suppose I'd fall back on the gauge menu that shows the speed in generously-sized font.
That said, although the issue may be a non-starter for me, I can see why it would bother some. I have a relative with a standard W205 and she has to use the digital speed readout because the numbers/hash marks on the physical speedo are too small for her to read.

It's a good question for an amg rep.... Next time you see one.
Not a show stopper, just a question.
Another thought crossed my mind ... You put the scale change in a place where the car will not be normally... So perhaps they figured most people would be running the autobahn.

I can ask some of the guys there and report back. I'm now curious as to whether the U.S.-spec AMG GT/GT S cars have this same interval change on their speedometers.
