Wal-Mart backs fuel efficiency drive
Wal-Mart, the retailer that operates one of the largest trucking fleets in the US, is backing the development of a new generation of fuel efficient hybrid truck engines, in a move that could accelerate the adoption of the technology across the industry. The retailer is working with Environmental Defense, a not-for-profit environmental group, on applying the technology used by passenger cars such as the Toyota Prius to the ubiquitous tractor unit that pulls the majority of US road freight.
