Yes, "tacho" means speed, in greek. So, when German engineer Diedrich Uhlhorn invented a speed measuring device, in 1817, he gave it such a name. First used for locomotives, then for other uses. Ever since named "Tachometer", in Germany, as of today.

Probably, he used the RPM of an engine as the base for a vehicle's speed measurement.

Then, the Englishmen came, and got it all wrong. :D Tacho for RPM and him for speed:

Could be just my word chooise being not correct again, not the first time. :lol:
Tacho is generally used for measuring engine rotations RPM, googling doesnt give you much else either.

I have to confirm this bug on a vanilla game. The speedometer stops at 120 km/h, but the maximum is 125 km/h on the speedometer. For the UK variant the speedometer stops at 73 mph, but the maximum is 75 mph.

Also SCS Software have missed the small "125" marking on the speedometer.

Tacho/Tachometer as in speedo and rev counters are intrinsically the same, BOTH use geared reference of revolutions of something to infer something, be it RPM or MPH\KM/H, though now in modern times rather than there being a flexible drive from the engine and the output end of the gearbox, it is normally a pulse generator.

e.g. with my Unimog when on the road and doing >10km/h I use the speedo, when doing precision working <15km/h is use the rev counter to infer speed vs. gear selected thus overall gear ratio vs. tyre SLR thus wheel circumference which is on a handy chart, as sometime I can be working as slow as 30m/h trenching other times it may be as high as 500m/h (0.5km/h), likewise tachograph/speedos can be relatively inaccurate <15km/h as the pulse generators are often working at <50Hz at this low speed vs. say a modern rev counter that will be at >400Hz at engine tick over.

But in short speedo and rev counters BOTH use revolutions of something to infer the scales value shown on the face of the tachometer, in the case of a rev counter it’s just a 1:1 representation per min, while in the case of a speedo, is RPM of the output shaft vs. differential etc ratio in the axle/s vs. wheel circumference thus linier forward speed per hour.

Vehicle Tachometer = speedo
Engine Tachometer = rev counter
BOTH are tachometer as they show the speed of something relative to a unit of time both of which are derived from the amount of times something has turned per the unit of time. ;)

Now, back on topic. .this is not a bug, I think...

Not a bug. Any vehicle that goes faster than what the speedometer allows will behave this way. Many, many years ago, I had a modified Datsun 120Y. It had a top speed of 183Km/h, but the speedometer stopped at 160Km/h, so the only way I could find out the actual top speed was for someone else to drive beside me in a different vehicle at over 160Km/h.

I understand what you guys meant. But the bug here is that the TGX speedo allows up till 125 km/h, but it stops at 120 km/h. Here is a photo I took ingame, look closely at the speedo and speed. Same applies to the UK version.

Unco, let me guess... That other driver was the police right? :lol:
