See this Edmunds.com article! EPA Overhauls Fuel Economy Estimates for 2008 - As the 2008 model-year cars hit the lot, shoppers will notice a big difference — the EPA has changed its fuel economy testing methods to produce mileage estimates that reflect "real world" driving habits. - (more)

It does not bother larsb because he got in under the old tests that favored the hybrids. The Prius tax credit of $3150 was based on it getting 60 MPG City, as rated by the EPA. The new VW TDI is based on a very low 29 MPG City estimate. That means it is affecting the pocket book of those that want a 50 state clean diesel. All of the diesels fare poorly with the new tests. VW has complained to the EPA and now GM is complaining as it will have a tremendous affect on their new Volt if it is only rated at 48 MPG. Hopefully the next President will shake up that lazy bunch of bureaucrats in the EPA. You have to take into consideration that Larsb would argue the moon is made of cheddar cheese if he could find someone to argue with.

Replying to: gagrice (Sep 15, 2008 12:25 pm) Gary says, "It is that tax credits are based on those tests." You are mad about ONE CAR out of 615 cars getting a low result. Get OVER it already. Gary says, "It does not bother larsb because he got in under the old tests that favored the hybrids." I did not profit much at all from the old tests. And the car with which I earned the tax credit changed from a whopping 39 to a whopping 34 with the new test. So you are wrong about that too. Gary says, "You have to take into consideration that Larsb would argue the moon is made of cheddar cheese if he could find someone to argue with. " Pot, meet Kettle.

Replying to: larsb (Sep 15, 2008 12:44 pm) NO, now there are FIVE diesel vehicles all being under rated by the EPA. All have gotten their Tax Credit posted on the IRS site. Much lower than they should be compared to the darling hybrids. All 3 of the Mercedes diesel SUVs will save a LOT more money per year than the Prius. Your anti diesel glasses are SO DARK you cannot see the truth.

Replying to: gagrice (Sep 15, 2008 12:53 pm) Allow me to refresh your memory: When EPA was doing the revised testing, they had 615 cars to test with the new method and only ONE of them was a diesel. They did not have enough data to worry about tweaking such a small data set. And of the five currently "tested and tax-credited" vehicles, I have not heard you complain that any of them were "robbed" by a faulty diesel test bias other than the Jetta. Did the MB diesels somehow avoid the bias?

Replying to: larsb (Sep 15, 2008 1:00 pm) No, they are just as far off as the VW Jetta diesel. They are rating the blutec R class at 18 MPG city. Probably off at least 25 percent from what owners are getting. At the very least they are off by 18% that the EPA admits to. At the very least they need to fire the top people at the EPA and clean house. They have yet to post the tax credit for the E320 CDI blutec. It is no wonder our Congress has an 8% approval rating with the way they run these agencies.

Look at the owner estimates for the 2009 Jetta TDI automatic tranny at fueleconomy.gov website. The City result for the three owners is 34 MPG. Below the 38 MPG that VW "independently" tested, and above the 29 MPG that the EPA tested. Seems like BOTH tests were sucky for the Jetta TDI city driving, no? Gary, are you going to be mad at VW now like you are at the EPA for "overstating" Jetta mileage?

Replying to: larsb (Sep 15, 2008 1:09 pm) You love to cherry pick your data. Where did you find a 34 MPG city from any owner? Check the one person posting for the stick shift model he is getting 49 MPG Check the 3 people posting for the automatic they are averaging 37.3 MPG The lowest had a 34 MPG average and the highest 43 MPG. Much better than even the company that VW hired to test the cars. I you check the Sportwagen the only person posting is getting 46 MPG. While all those buying the VW TDI will get the last laugh. I am not cutting the EPA one INCH of slack. So you can post all the tainted data you can find. And I will debunk it as usual. |

Replying to: gagrice (Sep 15, 2008 1:09 pm) I can't find too many good road test or any owner reports. Found one owner reporting 27 MPG lifetime on an R320. Another guy says he "has seen 22-23 mpg" and another one said the service department got 17.5 MPG when they brought him the car. An estimate of 21 MPG combined might be a little low, but it's not ridiculously low. If the best we can find is an owner getting 27 MPG then I can see why MB did not complain about the tests.

Replying to: larsb (Sep 15, 2008 1:23 pm) The difference between 21 MPG and 27 MPG is 23%.

Replying to: gagrice (Sep 15, 2008 1:42 pm) Prius: Ranges from 39.3 to 51.8 = difference of 31.8% HCH: Ranges from 42.5 to 50.8 = difference of 19.5% Insight: Ranges from 52.3 to 63.3 = difference of 21% Seems about a correct range of variance among highly efficient cars. |
