    EPA Wants Manufacturers To Test MPG Claims In The Real World

    • Real World Testing and the EPA Wants It

    After a number of automakers having to revise their fuel economy estimates, the Environmental Protection Agency is proposing that automakers run their vehicles in the real world to see if their estimates hold any water.

    "Some auto makers already do this, but we are establishing a regulatory requirement for all auto makers," said Chris Grundler, director of the EPA's Office of Transportation and Air Quality.

    The EPA's proposal would have automakers run their vehicles on a test track to measure air-resistance and rolling friction. At the moment, most automakers use computer models to generate this data. But if the wrong data is put in, it could cause mileage numbers to inflate, such was the case with Ford in their most recent revision.

    The EPA does note that a few OEMs do real world testing, but it hopes that it can make the testing a requirement for all.

    ABOUT TIME! They should be doing real world testing on all Auto's period. I bet we see a drastic drop in MPG for everyone as real world driving does not match computer generated perfect situations.

      Mitsubishi Motors brought in investigators to answer a question; why did they manipulate fuel economy figures on a number of their models? The results of the investigation were announced yesterday and it was a combination of various decisions and factors that led to it.
      The investigation criticized the company for "not having the manufacturing philosophy of an automaker". A key example comes from the company not rallying their workers to help them back on track after two major scandals. Instead, it was focused on cutting costs wherever it could. This caused Mitsubishi engineers to pull off the impossible task of improving fuel economy on their current engines and not developing new ones. There was also the feeling that workers couldn't speak up about reaching these impossible targets.
      The investigation also revealed that management failed to the address the possibility of something fishy going on with the fuel economy testing. In 2005, a new employee brought up concerns about fuel economy figures being made up. This was brushed off by managers. Six years later, a compliance survey addressing other falsifications were not brought to Mitsubishi executives.
      “The problem is not only with the testing, certification, or the development department. It’s a collective failure of Mitsubishi Motors as a whole, starting from the management,” said Yoshiro Sakata, one of the investigators appointed by the company at a briefing yesterday.
      “I take the panel’s recommendation seriously,” Mitsubishi Motors Chairman Osamu Masuko in a statement.
      “The efforts we’ve been making since I took over in 2005 haven’t been enough.”
      The investigators made a number of recommendations to prevent something like this from happening again. They include,
      Revamping development Making vehicle certification department independent from the research and development department Restructure the organization structure Being more transparent Understanding laws Be willing to find and tackle violations

      The EPA, National Highway Traffic Safety Administration, and California Air Resources Board have released their draft Technical Assessment Report on the 'Midterm Evaluation of Light-duty Vehicle GHG Emissions Standards for Model Years 2022-2025'.
      Despite the long name, this report is important as the results will help determine if the 54.5 mpg corporate average fuel economy target for 2025 needs to be adjusted or not.
      Let's begin with the good news. The report says the industry is “adopting fuel economy technologies at unprecedented rates.” Automakers and suppliers have been hard at work on developing new technologies to improve overall fuel economy and emissions. The report goes on to say with the improvements being made on gas engines, automakers will not need to rely as heavily on electric or hybrid vehicles.
      Now for the bad news. According to Automotive News, government officals have taken the 54.5 mpg goal off the table. Low gas prices and the high demand for trucks, SUVs, and crossovers have caused officals to rethink the goal. The government now belives the fleet average for mpgs will land between 50 and 52.6 by 2025.

      If you're wondering when Volkswagen will resume sales of diesel vehicles in the U.S., you're going to have to wait a bit longer. Automotive News has learned that the German automaker hasn't applied for the necessary EPA approvals to start selling diesel vehicles in the U.S.
      "They need to address our concerns" before sales can resume, an EPA official said.
      Those concerns most likely relate to Volkswagen coming up with a fix that meets the standards of the EPA and California Air Resources Board (CARB). As we have reported previously, Volkswagen might not be able to fully fix some of the TDI vehicles.

      On Friday, Mitsubishi Motors announced that it will set aside 50 billion yen (about $480 million) this fiscal year to compensate buyers for inflated fuel economy figures. Bloomberg reports that the Japanese automaker admitted that 20 vehicles sold in Japan within the past ten years had false fuel economy data.
      Mitsubishi said in a statement they used “desktop calculations” instead of running actual field tests and used the false data on the twenty models built from 2006 to this year. They also lowered the resistance readings on some models to give better fuel economy numbers. Mitsubishi reiterated they didn't find any false fuel economy data on models sold overseas.
      The compensation plan will see Mitsubishi pay 100,000 yen (about $955.63) to each minicar owner and pay for the difference in gasoline and taxes separately. Mitsubishi also announced that it expects Japan's transport ministry to approve the recalculated fuel efficiency ratings of its minicars by the end of the month.
      One more thing: The investigation being done by three former prosecutors into the scandal are expected to present their results sometime next month.
