First number or first two numbers are the chassis rating in tons and the last numbers are the horsepower rating of the engine (I believe) 911= 9 tons with 110 horsepower. 1117=11 tons and 170 horsepower.
Which, confusingly, is completely different from the way Mercedes did Unimogs. On them, the "sales designation" is an intial "U" (to show it's a Mog) followed by the horsepower with a trailing zero. So a U2450 has 245 horsepower, a U1300 has 130 and a U1100 has 110.

Except that this doesn't work very well. There are U1100s with 90 hp and U1300s with 150, and the sales designation didn't help any to identify how old the Mog was or the chassis capability. And they didn't even follow their own rules, at one point dropping the zero on some models, so they sold 90 hp U90s and 140 hp U140s while also selling U1250s and U1700s. (And the sales designation for the popular gas-powered Mog was, unhelpfully, the Unimog S.)
Then again, there's also a "model designation" taken from the first three numbers of the VIN. Under that scheme, the S morphs into the well-known 404, the U900 is the 406, the U1100 is the popular 416. However, the newer big trucks are all 435s and you have to identify them with the more numbers from the VIN. as in 435.115 for most 1300s.
Bad enough as is, but now the current Mog lineup has just the "implement carrier" U300, 400s and 500 (of which the U500 was imported into the US by Freightliner) and the more off-road-oriented U3000, 4000 and 5000. Their engines run from 156 to 268 hp, so no clue there.
In point of fact, in the US, older "round" trucks usually go by their model designation, while 80s and later "square" trucks more often go by the sales designation. So you'll most commonly hear of 404s, 406s, 411s, 416s, and 421s but, probably because they are generally all 435s, people speak of U1300s, U1700s, U2450s, etc. Except for the U500.
Clear as mud, ain't it? :sunflower If you really care, there's a good write up at:
