Why can you only get Detroit engines in Freightliner and western star

Wondering if anyone knows the reason you can not get a Detroit in anything but a freightler and western star nowadays?
I know international, Peterbilt and kenworth all used to have Detroit as a option but it seams like nothing after 2003.

 

Freightliner owns Western Star and Detroit Diesel.

 

I know that but is there a reason they no longer offer it in any other trucks since 2003? I have had a 2002 international and a 1998 kenworth with a Detroit. They once sold them to other truck manufacturers, I’m wondering why they do not anymore.

 

They don’t want to sell to the competition.

A lot of people are brand loyal, there used to be people that would only buy a W9 with a Detroit. So Freightliner was hoping they would be more loyal to the engine than they were the truck.

To simplify that GREED is why.

 

Makes sense. Thank you.
So I doubt it will ever be a option again

 

Probably not

 

Before it was called Detroit, it was called GMC Diesel, and all the trucks had them. I agree, it's greed that is preventing them from being sold in other trucks.

 

Why even care?Detriot hasn’t made a good motor since the 60 series ddec.

 

Has anybody then?

 

Not really except I’ll take the mp8 mack over the old mack motors but that’s it.
