7 + 3 = 10

The Run on Less roadshow tracked seven trucking fleets around the U.S. and Canada over a 3-week span to showcase highly fuel efficient tractor-trailers using off-the-shelf technologies. The Run...7 fleets put the U.S. average fuel economy of 6 mpg in their rear-view mirrors long ago. Run on Less was a great way to help to get the word out to the rest of the industry that these results are no...

The latest paper by the Center for Automotive Research is not what it thinks it is

Last month, the Center for Automotive Research (CAR) released a report on the potential economic effects of EPA/NHTSA’s 2017-2025 light duty rule. Although CAR receives funding or research support...The whole report rests on a false premise about the costs of meeting the standards. And whether that reflects a lack of "objectivity" or something else, it renders the report completely unreliable as...
