Hearing rumors GM and Navistar teaming up ?

But didn't Ford modify the 6 liter diesel for more power than IH tuned their version for IH ?. Maybe some diesel experts out there can confirm whether IH had the same problems with the 6 liter, as did Ford.

I've wondered about this for quite awhile, wonder if anyone has the answer.

BTW, I would like to see GM get back to larger MDT and HDT vehicles. Partnering with IH Navistar seems like a good way to go.

correct... look at how many buses and delivery trucks which had the 6.0 powering them. It was a ford engineering err...

PS - I used to drive a TopKick 6500 with the CAT diesel. It was a turd. Slow, thirsty, noisy, hot.... The only thing I liked about it was the cab, and the ride (compared to the cabover trucks).

If not, doesn't GM still own Detroit Diesel or did they sell that? Years ago you could get a GM medium duty with a CAT. Now that would be cool.

Detroit Diesel has been a wholey-owned Daimler brand since 2000. Fun fact: when you select between a Mercedes and Detroit Diesel in your new Freightliner, the only difference is the valve covers :)

CAT is no longer certified to sell on-highway diesels (they gambled on EGR instead of Urea-post-treatment, and never got it working right so they threw in the towel). The CAT-branded trucks are actually a Navistar joint-venture, but some of those even have a Cummins after Navistar was de-certified for a while, after they were caught cheating on their EPA test. It turns out Navistar never actually got their EGR system fully compliant either... They caught caught, paid the fines, and then had to dig out of the while using help from Cummins. First by supplying motors, then helping them quickly develop a Urea-based after-treatment.

I'd be glad to see GM re-enter the medium duty market.
I would never buy one with a Navistar engine after the Ford fiasco.
I don't know why they would need them anyway. The Duramax is more than up to the task I would think. If not, doesn't GM still own Detroit Diesel or did they sell that? Years ago you could get a GM medium duty with a CAT. Now that would be cool.
