I don't have much to add at this point, but yall need to do some reading on how diesel's work. Diesels are roughly 56% efficient where a gas engine is 25-30%. Smoke does not equal power, to a point. My larger tunes smoke some until the Turbo Lights, then they clean up to zero smoke.
Buy what you want, but I bought a diesel, so I don't care what you gas burners think
You're not going to find a 56% efficient diesel anywhere. It's very unlikely that you'll find one that efficient in your lifetime.

I looked at your first link. The 56% fuel efficiency number mentioned there is based on a mathematical calculation that assumes things like no friction or heat loss.
The most fuel efficient diesel engine in the world as far as I know is the Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine I believe it achieves its maximum efficiency of just under 52% at about 90 rpm. It runs on heavy oil which has more energy than refined diesel and is about 1/2 the price.
For truck and passenger car diesel engines a maximum efficiency of about 41% is likely a good number.
