Back in December, I wrote about the government’s efforts to improve the [fuel economy](http://www.justmeans.com/blogs/new-epa-standards-a-big-win-for-truckers) of the thousands of tractor-trailer trucks that crowd our highways accounting for millions of gallons of diesel fuel and tons of carbon emissions. One prong of this effort was a five-year $115 million DOE project that challenged truck makers to see if they could achieve a 50% reduction in fuel consumption.

Now, [Freightliner](http://www.freightlinersupertruck.com/#tomorrow) has announced their success, as they unveiled their [Supertruck](http://www.foxnews.com/leisure/2015/03/26/freightliner-supertruck-hauls-goods-sips-fuel/).

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.
