I don’t understand why the automakers are not introducing the high torque, low displacement turbo charged diesels in trucks by now...The large trucks by now could be getting 28-32 mpg if they were to put these in...

I think the diesels will eventually get here...but a lot longer than they should...

When you put a 3500 pound payload and chains on all 4 cornere of a 1 Ton, 4x4 truck then start driving through 10-12 inches or more snow on rough, hilly terrain, it takes horsepower AND displacement to pull the load. If those kind of engines worked in trucks, highway transport trucks would be using them.

My Sprinter van has just such an engine. It is a 5 cylinder Mercedes diesel and the van. It does not get 35 mpg but it cruises at 70 mph at 23 mpg. At 55, it gets 26 mpg

The Democrat Environazis have fought tooth and nail against the diesel for years. Until recently you couldn't even BUY a diesel passenger car or truck in California or Massachusetts.

The diesel dodge 3/4 and 1 ton trucks get in to the high 20’s. The splinter van has been known to flirt with 30 mph. Remember the junk diesel engines of the 80’s? There is a reason. Now look at zero’s epa. There is another. Ford has many Diesels out of our country. The festiva diesel gets 45+ mpg. Allowing us to buy those would kill the dolt and other over priced gas/electric cars.

These requirements don't kick in until 2016. They have four years to refine a truck which will deliver the mileage. The popularity of the small utility truck is not going away, so the market will provide the incentive.
