Now they're putting their light duty 5.0 V8 diesel in the Titan. That motor has been around a while in commercial applications, so it should fair well in a 1/2 ton truck.

Sorry, you have that backwards, Komatsu uses Cummins Engines in their Machines...

Nope you have it wrong. The QST-30 engine sold under the Cummins name is actually a reworked Komatsu. When I was working we had one of the QST-30 V12 750KW Onan/Cummins diesel generators. Seems they both use each others engines. We had a few Komatsu diesel engines, we're very nice running engines.

Cummins Engine HQ is in Columbus, IN, but they have engine manufacturing plants world-wide. My first visit to Columbus, their maintenance dept. had installed ISB engines in their Ford work pickups.

They have made millions of the small 5.9L and up in size for industrial use, road graders, back hoes, air compressors, emergency power generators etc.
Also millions for farm equipment, tractors, combines, harvesters etc.
Also millions for MOHO's and Ram Trucks.
And again millions for OTR trucks.
I don't know that Cummins has made as many diesel engines as noted above. But they are a major source of over the road tractor engines, but Detroit Diesel, Mack and Paccar also make competitive engines. Navistar bet their company on engineering a new generation big diesel without DEF, but they lost $ millions when the engine would never past Tier IV emissions standards. They're now using Cummins engines in their over the road trucks.

Cummins is also building a new diesel engine going in the next generation Nissan Titan engine after Toyota contracted design and building the engine--and backed out of the deal. They've probably offered Nissan a deal they couldn't refuse.

The Cummins diesel engines used in 3/4 ton and 1 ton Ram trucks are popular and well thought of, but Ford's PowerStroke engines still outsell Ram/Cummins and GM's Duramax diesels combined.

Ram's new 1/2 ton diesel is called a Ecodiesel, and it's coming out of one of Fiat's high tech diesel engine factories in Italy. Fiat and their subsidiary companies like Iveco, Man, Case and New Holland is actually the largest manufacturer of high tech diesel engines in the world--and they put out fantastic engines.

Yep! In the following year the rules were changed to eliminate diesel engines from competing.It was blowing away the competition.
