Navistar to start building GM midsize Vans

Probably the biggest problem with the Ford/Navistar diesel engine is that Ford demanded the engine ready for production in 2003 because they were getting their lunch eaten by Duramax and Cummins and the 6.0 engine was still approx 2 years from being actually ready with the bugs worked out and thorough and complete reliability testing having been completed. On file is the objection from Navistar for early release for production. Ford made the rules and had the controls it bit them hard! Notice that Ford didn't win their big lawsuit with Navistar? Both had some fault in the matter but Ford called the shots!

The release of the 6.0L later in 2003 was due to the upcoming 2004 emission standards, nothing more. It is the same reason why Cummins went to high pressure common rail in 2003, and the Duramax LLY engine was introduced in 2004. If you look at the changes of all the pickup diesels along with the different Ford diesel engines and the 1994, 1998, 2004, 2007, and 2010 emissions standards changes, you will notice they coincide with each other.

Also, I am not sure what you mean by getting their lunch eaten. The 2001,2002, and 2003 7.3L with an auto trans made 250 hp/505 lb-ft, the 2003 Duramax auto made 235 hp/500 lb-ft, and the Cummins auto made 235 hp/460 lb-ft. Where in that do you see the 7.3L having it's lunch eaten?
