Random question but I’m sure some will know the answer.
What do the numbers on Mercs actually relate to. ie: 2551 1836 1860 2544 etc etc
All other manufacturers seem pretty obvious what models are what & HP etc but just curios about mercedes meanings !!
Boring post I know, no mention of cyclists or stobart !! Hope everyone can cope 
lol
Cheers
the 1st two numbers are the chassis gross weight and the second two bhp divided by ten IE a 2546 is 25 ton chassis with a 460 bhp engine.i drove an 1857 on birds 18 ton chassis 570 bhp engine simples 
I’m not sure the first two digits are down to weight although 18 are usually 4x2 and 25 are 6x2 even on rigids although the second two are the power rating (or close too )
Well after 3hrs sat in a layby at least I’ve learnt something new !! Lol
Cheers chaps

Gross weight load on the chassis, so a unit with an 18 can only ever be 18 tonne as the axle would be overloaded otherwise (the other 20 tonnes is born by the trailer axles), therefore a 25 would have to be a 6x2 as you can spread the extra 7 tonnes over the extra axle.
Mercedes have had this way of doing it for many years, way back my first Merc was a 1617 and that was the same numbering convention 16 tonner 170bhp - and it goes back way before that, it is one of those things that once some ones told you is obvious- but if no-ones mentioned it can seem baffling- no such thing as a daft question if you genuinely don’t know the answer
Only exception being the smaller stuff, 815 is a 150 brake but normally plated to 7.5 so it fits on a C1.

Not only badged for the Uk market !

I’m glad this thread got started, was going to ask the same myself 
Actually the second two numbers are the quoted BHP/10 and the first two are the actual output 
2544 - quoted 440 bhp - actual output feels more like 250

Lol ill second that once had an 815 beaver tail 7.5 tonner the 15 bit was being modest I thought the 8 was more realistic it felt like 8hp every time you hit a hill or even level ground bloody thing.

Ford did it better ; Cargo 3224 - 32gtw, 240bhp - simples!

I used to drive some Iveco 130E15 (13t 150bhp) with alternator driven fridges. They were hateful things that couldn’t pull a greasy man out of a bath. With the fridge set to freeze you had to turn it of to climb hills.
Not forgetting the 4 digits Foden used ie 4300 (4000 series 300bhp).
I drove a Merc Atego demonstrator 6w and that was 2628. I believed the first 2 numbers…

I dont think Ford did anything better when it came to Trucks…or cars really. just my opinion of course
Leyland did similar, my Dad had a Constructor 24.21
