  • 2014 Ram 1500 EcoDiesel, Bear Mountain, May 2014

    Talks appear to be breaking down between the U.S. government and Fiat-Chrysler Automobiles over the automaker's alleged use of emission defeat devices. Now, according to Bloomberg, the U.S. Department of Justice is preparing to sue the automaker if talks fail to resolve the issue. Previously, both sides were said to be nearing an agreement, though things have reportedly gone south. The lawsuit could come as soon as this week if discussions continue to erode between the automaker and the EPA. As far as U.S. officials are concerned, FCA has not been able to fully explain the purpose of its...

  • Wave Disk Generator engine

    There may be life in the old dog yet - engines have never been the cleanest of machines, requiring fossil fuels for their power and releasing all manner of gases, elements and chemicals through the combustion process. Carmakers have come on in leaps and bounds over the last few decades to make the internal combustion engine cleaner than ever whilst improving economy and performance, but ever-tightening emissions regulations worldwide are certainly making things difficult for the industry. Help could be at hand though, in the form of the Wave Disk Generator (WDG). Conceived by researchers at...

  • Los Angeles Smog

    The U.S. Environmental Protection Agency this week granted California a long-anticipated Clean Air Act Waiver. Under the plan, California - along with 13 other states - will enforce its own emissions standards until the 2012 model year, when the federal government will begin phasing in new national standards that will require a fleet average of 35.5mpg by 2016. The issue dates back to 2004, when California adopted standards that were then significantly tighter than those of the federal government. Under the Bush administration, California had been denied the permission by the Environmental...
