Input: Question: The US emergency telephone number 911 seems to be almost always pronounced as nine one one whereas the Porsche model is typically pronounced as nine eleven One reason I can think of for preferring "nine one one" for the phone number is that there is no "eleven" key on a phone. On the other hand, "0800" is often pronounced "o eight hundred". Is there a logical or historical reason for the different pronunciations? 
Answer: That the emergency number 911 is pronounced nine-one-one is probably a standard to avoid confusion or doubt by either children or non-natives to the English language. Pronouncing the number as nine hundred and eleven could be misinterpreted as 90011, hence the emphasis of three digits. This is also a deal in most European countries, where 112 is the emergency number and pronounced 1-1-2 in the languages I know and for all I know in other languages too. one-one-two (English), ein-eins-zwei (German), et-et-to (Danish), einn-einn-tveir (Icelandic).
