Why does everyone have a huge boner for Diesel?

Diesel burns slower so you can take advantage of a much longer stroke to produce more torque. They have higher thermal efficiency, roughly 10% better which means less heat is wasted -- meaning less energy wasted. More BTUs per volume of fuel, about 11% more, and generally double the compression (due to direct injection) which means more PSI generated and more PSI generated when combusted which means more output with better economy. And of course no throttle plate/butterfly valve to restrict air flow, power output is controlled by fuel.

Since you mentioned it...

 

Diesel smells like shit, keep it off the road

 

diesel smells amazing!

 

sorry, didn't want to hack up your quote too much.

Truth is most or none of us have experience in small diesels in autos, I have some but they are all back-hoe type / ag type. Think on high idle a lot and no accelerator.

The diesel engines today do extract a lot of the energy in respect to smoke, but they can still do just that at times.

As far as diesel not ready for Americans, we might not be ready for the small diesels. I suspect a 4L is better accelerating than a 3L diesel, but I dunno. Acceleration for me is 3rd in diesels after towing and mpg possibilities.
Add the diesel to gen3 problems ,right.

Ok Ok Ok you like the smell of shit.

 

have you seen a modern diesel car run? my grandpa has a mercedes diesel, no smoke from it, i drove a golf TDI at the body shop i worked at, no smoke,my dads 05 f-250, only smokes when you're at redline trying to pull a 7 ton trailer uphill.

Lies!!!!!!!!!!!!!

1.9 ALH VW street able engines can make 300 HP with around 400 FP torques (using VW parts no after market stuff) not a real cheap endeavor but there are a lot of them out there. After market hears etc well in excess of 500 HP. Not too bad when you figure they started at 90HP.

 

No kidding... When it comes out in the US we may have to trade up!! Drove a Passat wagon for a while and the thing went everywhere! MPG's sucked big time so throw the TDI in there... Bam! That would be one sick machine

 

Most older people remember GM's abortion of an attempt at diesels back in the early 80's. they just took a regular gas engine and somehow converted it to run on diesel. The results were less than stellar, along with their build quality. That alone probably prevents most of the older demographic from purchasing one.

 

When you ask a girl what kind of car she has, more often than not the answer will be something like, "A blue one". A lot of people seem to think of diesel engines the same way. There's a huge difference between a non-turbo, mechanical injector pump Caterpillar dozer engine, a VW TDI and everything in between. I did the Dodge Cummins Turbo Diesel thing for 18 years and have a fair amount of experience with other diesel set ups. In that 3/4 ton Dodge, that early model, mechanical pump 12 valve Cummins turbo was bulletproof but the rest of the truck sucked. Diesel's have their place and in some parts of the world they hold a large share of the market. A lot of it comes down to the design of the set up. The old Toyota FJ diesels were very solid designs but wouldn't be popular in North America (too slow, too much cost up front) One of the popular diesel conversions for Jeep's is a Cummins 4 cylinder diesel but it's costly.

You have that wrong. Diesel is a byproduct of redneck sweat.

 

I've driven a few of the Benz diesels. Not bad overall. You sacrifice some speed. You get more low-end torque.

Cons: expensive as hell to fix, occasional smoke.
Pros: somewhat better mileage, 500,000 mile engine, fuel keeps a long time.

The third "pro" is something a lot of people overlook. Even ethanol-free gas won't keep more than a month without fuel stabilizer, and that only does so much good so long. Diesel will keep for six months with virtually no precautions for all, and a couple of years if treated with the appropriate anti-bacterial and anti-water agents.

 

Speed? Our old 300 SDL would get to 115 quickly. How fast does one need to go? It still got nearly 30 MPG doing 80-85 all day.

Expensive to fix? Agreed! Kind of obvious when OEM parts come from Germany. Luxury cars cost more to repair, generally, don't they?

 

FTD mentioned the expense of repairing diesel's and I've heard that same comment from many others. I just don't see the added expense of repair. I think there's always a little bit of fear about diesel's because they're different from gas engines but in practice they seem to cost less over the life of the engine. Yea, one could experience a catastrophic failure with a diesel that was expensive to fix but that can occur with a gas engine as well. In my experience diesels just don't break as much and are actually cheaper to operate over the life of the engine (which is long as FTD pointed out)
The fuel issue is one that I hadn't considered but there is a downside of storing fuel. Diesel has an affinity for water and will absorb water vapor from the air if not stored properly. If it's stored properly it will last a long time.
Overall - I think a diesel would be a great Toyota truck engine if Toyota doesn't screw up and go cheap on the design. I don't think an inline 6 would fit in the current engine bay of a Tacoma so I guess it would be a V-6 diesel?

 

My family and turbo anything just doesn't mix well

 

Another con about diesel fuel is if it gets cold enough, it starts to gel.
