With the Recent Unveiling of the International S13 and the 2017 release of the A26, They obviously had the capability to produce their own engines again. However by this time, Navistar has already determined that the EGR is not feasable for Diesel Engines, and went with SCR like Cummins. Soo, why hasn't Navistar started producing engines for School Buses again? Let me know down in the comments below.
This is a followup to the last thread that I made regarding this topic. I worded it correctly so that it's actually focused on the original intention of the topic, which is where this thread comes from.

Why did they switch to cummins engines to begin with? Navistar was using EGR to meet 2010 Emission Standards, however this caused the engines to break down more and more. In response to this, Navistar began to phase out it's Maxxforce engines with Cummins, until they had fully replaced it's lineup with Cummins. |

Though emissions strategy was an initial factor driving the change, the power of numbers is also what happened. Within the medium-duty truck segment, Class 6-7 is pretty much a monopoly held between Freightliner, International, and Ford. While Ford uses its own diesel engines (as an option to gasoline), the Freightliner M2 has used Cummins diesels for nearly 20 years. In moving towards SCR diesels, adopting an engine platform that offers a degree of mechanical commonality is highly appealing. Not only did International do this for its medium-duty trucks (where its buses come from), but so did Blue Bird and Lion buses (the latter, when they still had engines  ). In another example, medium-duty Kenworth/Peterbilt trucks (if you can find them) have PX engines....designed and manufactured by Cummins. |

It seemed like Navistar was really intent with keeping it's own engines. I don't think they would have switched to Cummins if their Emissions strategy didn't fail. Also, buyers at the time were already interested in Navistar's engines, AND in a market where almost everything is powered by Cummins with the exception of certain truck companies like Kenworth, Mack, Volvo, etc. While Navistar has begun producing engines again, they've probably come to realise that commonality is becoming a trend in the market and offered the International engines alongside the Cummins. |

Also, my Question STILL hasn't been answered so I think I'll provide myself with a possible answer.
I believe Navistar is Nervous to produce Engines for Buses again because of its strategy failure. Districts that have owned IC Buses Between 2008 and 2017 have experienced Problems with their Maxxforce Engines. Obviously, that would make them Hesitant to buy buses from IC Buses iwith Navistar engines.
Now, these districts can only rely on Cummins to power their buses, and they'll refuse to buy any buses with Maxxforce engines.
Navistar is just taking it really cautiously around the Bus Market, and Even if they did produce an engine for the buses again, I highly doubt they would replace Cummins as the Main offering, as they did with every other truck.

I haven't responded because I'm not knowledgeable on the topic but looking at things from a business perspective, I'd say you make a good argument. Some of the complaints have been well publicized and I would say that Navistar is being cautious. Also look at how Navistar has reduced their school bus options (eliminating the FE option, rumors of RE option being discontinued in the immediate future). With so much focus on clean energy and alternative fuels, it may be a while before we see something different from IC/Navistar. |
