Could not find the original thread i started on this topic. Looks like walmart may very well double its truck fleet fuel economy. 25% increase in 3 years is very significant and no doubt the rest of the trucking industry will adopt similar technologies.
In October, the Bentonville, Ark., retailer unveiled plans to make its trucking fleet 25% more fuel-efficient within three years. The fleet of 7,100 trucks already is on track to become 18% more efficient over the next year alone, said Johnnie Dobbs, Wal-Mart's executive vice president of logistics. "At this point, we feel pretty comfortable we can make the 25% goal," Mr. Dobbs said.

Mr. Dobbs said the bulk of the savings for Wal-Mart's trucking fleet thus far have come from the installation of auxiliary units that power the air conditioning when a truck is parked, eliminating the need to run the engine. Wal-Mart's trucks also are benefiting from wider tires that can carry bigger payloads, aerodynamic skirts and cowlings that cut wind resistance, and new additives that give diesel more bang for the buck.

The plans are a pillar of an environmental initiative that Wal-Mart announced with much fanfare in October. In addition to slashing transportation costs, the program also seeks to reduce greenhouse gases from existing stores and distribution centers by 20% over the next seven years.
As for new stores, Wal-Mart aims to introduce a design within four years that is at least 25% more energy-efficient. Those developments could also pay off, as the price of electricity and natural gas have soared along with the price of oil.
