Back in December, I wrote about the government’s efforts to improve the fuel economy of the thousands of tractor-trailer trucks that crowd our highways accounting for millions of gallons of diesel fuel and tons of carbon emissions.

The 65,000 pound semi, which is powered by an 11-liter hybrid diesel engine, and shrouded with a bevy of aerodynamic features, comfortably surpassed the target by 15%, with a demonstrated fuel economy of 12.2 mpg, more than twice the average of trucks on the road today. The test drive was performed between Dallas and San Antonio Texas.
