Pretty sure the majority of those you named are DIESEL ENGINES. Diesels produce more torque due to stroke length and the fact a compression engine ignites the fuel faster than a gas fueled combustion engine.



There's only one half ton diesel motor out there, and it's the Duramax 3.0L inline 6 from General Motors. I hear very good things about it. The inline 6 configuration is hard to package, but they made it work.

It has been far superior to the V6 configuration that the Ram used for their half ton diesels before canceling them last year.

The first generation of those things were massive piece of crap. I lost track of how many main seals ours spit out on the highway.

It's an oversquare I-6 turbo diesel engine with iron cylinder liners and a forged crankshaft. It's already at an advantage over the V6 competitors sourced from Europe. A relative of mine has one in a pickup and he seems to love it.

The only thing about it that concerns me is that the engine was originally designed for Isuzu/GMC cab over trucks, so the valve train is in the back of the motor....so that's going to eventually be more of a headache to service since there's less access back there in a traditional truck with a hood. General Motors could barely fit that longer engine in their light duty trucks.

I'm a little annoyed that you still can't get one in a Yukon, Tahoe, or Suburban if you get the off road package. It's frustrating because that's probably the best light duty truck engine right now.

If they ever made that engine more widely available, I'd probably consider trading my Toyota for a GMC.
