You heard that right guys. We are so aware of the past of these two companies. Starting January, Ford and Navistar were having this strained relationship. Well, of course, it’s all because of the engine units being supplied by Navistar for the domestic car maker.

Navistar has been the engine supplier of Ford for a long time. But months ago, a lawsuit was made because of the matters regarding the unreasonable price increase of the engines supplied by Navistar. However, after weeks of interrogations, Ford and Navistar have agreed to continue their business - with Ford to receive the engine from Navistar and the engine supplier to continue supplying the US auto brand with the engine.

After months, here they go again. The battle continues because of the engine… Again.

We all thought that the lawsuit would patch things up with Ford and Navistar. But now, another lawsuit has been made and has been filed. Before, they were negotiating about the large 6.4L Power Stroke, but this time, they are fighting over the smaller 4.4-liter diesel engine which is intended for the upcoming F-150 which is scheduled to be sent out this coming 2009 or maybe 2010.

To recall, Navistar sued Ford for breach of contract because of the 4.4-liter engine which was made available on the market. But this time the engine maker is questioning whether Navistar will be designing the new engine. That is the big question. They believe that another contract will have to be signed but, in any case, these two companies will end up messing up with each other.

Why doesn’t Ford give up with Navistar anyway? I guess Ford should find another engine maker to build the smaller 4.4-liter diesel engine for the upcoming F-150 model. With their break-up and make-up relationship, I guess there is no future for both companies to stick together.
