most capable off-road pickup?

My only input is that the inline 6 is the best motor design (inline 6 specifying not oil burner or gas). It is naturally the most balanced and therefore tends to be more reliable due to less stress from non-vertical forces acting upon it.

Other than that I gotta say if I had the money a power wagon would be on my list, but as a broke college student I can dream of a manual taco or even buyin a diesel hilux in Mexico :D

The inline six is very smooth, even without counterbalances on the crankshaft

A cross-plane V8 is just as smooth (forces acting on the motor) with a counterbalanced crankshaft. There is no difference.

A V12 is even smoother than the inline six, as it is basically two inline sixes with more firing forces per revolution.

Don't oversimplify it. There is a lot more to engineering a motor than picking the layout.

There are plenty of not-so-good inline sixes, both gas and diesel. There are plenty of good ones too. The Cummins I6 is a great motor for what it is. It has pros and cons. V motors have their pros and cons. Flat firing motors (boxers) have their pros and cons. Rotaries have their pros and cons.

It's just like saying "solid front axles are the best front suspensions" or "tall skinny tires are best" or "Diesel is better than gas" or "Manual transmissions are better than automatics"..... depends on the applications and which attributes you deem more important than others.

Who's going to be the first to use an aluminum block Audi R10 style diesel?? Imagine a 6L+ diesel that weighs about the same as a Ford v10! The towing power of the diesel, but the offroad prowess of a small block.....

We have the technology to get it done now. I Just wonder if it'll ever happen? If diesel engines keep getting more and more expensive, the billet quality block cost for an aluminum build might actually be competitive.

My Ford Ranger has to be the more capable off-road truck. hehehe Is there any company out there that ever used the 6 strokes engine concept, I remember reading about it a few years back. 5th stroke was injecting water on the piston surface to cool it down and the free 6th stroke of the water expending in steam, if I remember correctly it didnt needed a radiator cause of that.

Never seen that.

But water injection was common in 4 stroke WWII aircraft. Actually increased power quite a bit by keeping things cool. Water injection was banned from top fuel drag cars years ago. So they just run them excessively rich with similar effect. I used to use water to shock the carbon out of olde school tow motor engines. Darn things ran well with water pouring down the intake. Weird stuff.

I know there are methanol injection kits for diesel tuners. Similar idea to water injection but dryer. And propane injection actually seems pretty straightforward and reliable now.

Scania makes a V8 diesel semi for the European market than makes 730 horsepower and 2600 lb-ft torque.

It's called the R730. Someone should have told them about the inline thing. Poor engineers.

The Torque on that thing is impressive too.

That said, a Direct Injection with a 3208, with the pump would up a little will still make more power. Just you will be stopping for fuel a bit more frequently...

The Mercedes 3.0l V6 has had an Aluminum block for 8 years...
That said, it doesn't make a huge amount of weight difference to CGI block engines, and I cant envisage all manufacturers adopting Aluminum blocks for a number of years.
