On Edit: Point being, abuse was not covered and I imagine that's still the same policy for any brand. It wasn't hard to determine if that was the case or not once an engine, etc, was torn down.

The developments in common rail fuel injection allowing multiple injections has increased torque by giving a longer period of high pressure when the lever of rod connection to crank center is in the 90 degree range. Gasoline tends to build lower peak pressure and the pressure lasts longer and diesels were higher pressure but it was on the brief side. fueling over a few milliseconds has awakened the torque beat even more.
Since the loading of those engines is less than out usage in PU's they can go a bit further with it. I imagine the emissions, NOx in particular would be way up there on a heavy load engine running similar level of tune.

The best part about it is that all those ponies come with a warranty! My supercharged Mustang is making 367 hp at the rear wheels and I'm afraid to use them all because I don't want to blow something up.
Imagine being able to use those factory 350+ horses and never having to worry.

|LMJD||Yep, I saw a hour long feature on building the diesel BMW, engine and all, on "Best Factories" (or whatever) and it's an amazing machine. IIRC C&D said it had amazing torque too.|

The numbers they are getting from the passenger car diesels is borderline insane too.
BMW has a 3 liter with 381 HP and 546 TQ. Imagine a 762 HP 1092 Ft-Lb V12 under the hood of a 1 ton PU (and the highway patrol car with lights flashing behind you...).

I was reading about the Ford Ecoboost too, another powerful but small engine.

It's just like Ford's Ecoboost putting out more torque that the Hemi. It feels weird saying that a V-6 has more grunt than a V-8.
I was in your neck of the woods a few weeks ago for the Xtreme Bulls and the Cody Stampede. Do you make it to the Nite Rodeo very often?

|LMJD||Sounds like you read the same latest issue, they discussed the Honda F1 type engines too. The active suspension systems on the high end vehicles sound interesting too. I don't have a clue how they work or what's involved. Got to look around on the net and check into it sometime. Sounds like turbochargers on gas engines are the wave of the future. With a turbo they can get by with real small engines that put out gobs of torque and HP.|

The technology is certainly there. Getting everything to comply with EPA regs is another. Honda is manufacturing the 2015 F1 engine. It's going to be a 1.6 liter V-6 and put out somewhere around 800hp.
Eventually the technology in these engines will make it's way to the consumer. The big block used to be the king but before long, your weed wacker engine will be putting out 60 hp.

Modern Engine Technology
Can't believe the advances in engine development nowadays. Car & Driver has a writeup on a small 4 door Mercedes for public consumption (not a race car) with an engine that puts out 355HP and 332Ft/Lbs of torque. Not amazing numbers by today's standards except for this---the engine is a tiny 4-banger that's 122 cu.in. (2 liter) and weighs 326 pounds. The thing turns the 1/4 mile in 13.3 seconds. Also was a new Land/Range Rover with a 305 cu.in. engine putting out 510HP, 108 MPH in the 1/4 mile, 13 seconds. By contrast, the "hot rod" boys on another site say my old 7.3 IDI turns a blazing 66 MPH and 20 seconds in the 1/4 mile. With those stats as a starting point, unlike some of them, I just don't think I'll be spending a couple thousand on a hi performance IP or a torque cam.
