EPA Will Reveal MPG Test Data – Who Should be Afraid
For the first time ever, the EPA plans to release the results of their MPG testing in “plain English.” This will finally shed some light on what the EPA is seeing and provide an independent source for MPG estimates. Which automaker do you think is most afraid of the results going public?
The general public is starting to wake up and seriously doubt the EPA testing methods. This plus the cases of automakers stated way less than factual MPG numbers leads one to severely doubt the credibility of the EPA. Now, it seems the EPA has had enough.
In an Autonews.com story, Christopher Grundler, head of EPA’s Office of Transportation and Air Quality said that they will release the “results of industrywide audits that included tests on more than 20 car and light-truck models this year.” These audits include data that was meant to double-check the automakers “coast-down” test. The EPA did the tests at tracks in Arizona and Michigan. This is the same test that got Hyundai and Kia in trouble.
The coast-down test is one in which the vehicles speeds up to 80 mph and then coasts to zero. It tests the vehicles’ aerodynamics, rolling resistance of the tires and amount of fricition in the drivetrain. This test is conducted on a dynamometer. Taking data from this test and others, the EPA is able to project MPG.
Grundler said that after being briefed on the results, the report “will be very interesting to some people.” He can’t talk about it, because they are currently meeting with executives from car companies to brief them on the results.
As most of us now know, the EPA has rarely done audits of the automakers results and up until three years ago, didn’t do any coast-down verification. They started doing them to deter cheaters (see: Hyundai and Kia).
Also interesting is that for the EPA to do these tests, they have to rent track space or find a place to do the testing. Last year, the EPA was able to find a decommissioned Air Force base and this year, they rented a track from Chrysler.
While the EPA briefed the automakers last year on the results, this year is the first that they will be made public.
This brings up back to the original question, which automaker do you think has the “will be interesting to some people” test results?
Our money is on the Ford and their EcoBoost products. RAM could also be interesting as well since they have sent the truck for testing several times to get better fuel economy numbers.
Who is your pick?
