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)

Replying to: gagrice (Sep 25, 2008 11:53 am) The credits have to be tied to some metric. The feds have a tendency to hang everything on efficiency standards and draw parallels to other issues. That's the basis of the current dispute between your state and the feds. Feds say increased efficiency alone is enough to achieve emissions goals. CA says the feds dismissively discount other approaches to reducing emissions. I'm not entirely convinced that reducing emissions was much of a motivation in crafting the tax credit system, but rather it is just a nice bonus. I would guess the feds saw city MPG as the area that provided the most potential for improvement, so that's what they focused on. In doing so, hybrids end up benefiting more than other technologies. |

Replying to: larsb (Sep 25, 2008 2:50 pm) Maybe you can explain why the Prius is still given a 66.6 MPG rating for the 2008 Prius. Those numbers should reflect the new supposedly better tests? No difference from the 2004. You can check the datafiles all the way back to 1978. There is a difference for the VW TDI. So maybe they did in fact test them with the new test. They just used a formula for the Prius and who knows what other vehicles. Your mind is made up. There are folks here that are interested in getting to the truth about the EPA. What are we getting for the money spent? http://www.fueleconomy.gov/feg/download.shtml |

Replying to: steve_ (Sep 25, 2008 4:40 pm) The letter states. "Under the Energy Policy and Conservation Act, EPA is required to determine the test methods and calculations for two major fuel economy programs": CAFE and consumer friendly fuel economy information posted on new vehicle labels. larsb likes to argue that the tax credits are fairly allocated. If that was the case the criteria would be based on combined mileage not city only. This program was for alternative fuels and hybrids. Yet it was tilted toward hybrids by using city mileage as the criteria.

Replying to: gagrice (Sep 25, 2008 5:04 pm) I already explained that in full. The purpose of the hybrid tax credit was to get cleaner cars on the road. The majority of air pollution problems are in big cities, in densely populated areas, and is also the place where air pollution is most dangerous to the health of the citizens. So cars which do WELL and pollute LESS on the CITY portion of the test would be more beneficial toward cleaning the air. Thus, the hybrids, which were designed to perform well in city environs, were pimped to the public with the high City mileage in a part of the effort to CLEAN THE AIR. If you cannot latch on to that perfect logic, then you have personal issues.

Replying to: gagrice (Sep 25, 2008 3:45 pm) Brand Model Style City Hwy Unrounded city unrounded hwy SATURN ASTRA 2D HATCHBACK 24 32 27 30.9 45.1 VOLKSWAGEN JETTA TDI 29 40 33 38.5034 56.6944 TOYOTA PRIUS 48 45 46 66.6 64.8 This following paragraph will PUT AN END to the argument that the "Jetta TDI GOT SCREWED" by the EPA test. Because if you look at the numbers, the Jetta TDI was given a rating which was 75.3% of it's actual city test result, while the Prius was only given a rating which was 72% of it's actual test result. On the hwy test, the Jetta TDI was given 70.5% of it's actual test result, while the Prius was given only 69.4% of it's actual test result. So the TDI actually was given a BETTER NUMBER than the Prius based on the formula. So now, Gary, FINALLY you can GET OVER the problem/issue you have experienced regarding your completely FALSE belief that the Jetta TDI got screwed by the EPA. The numbers PROVE YOU WRONG, Amigo. Time to be a man and admit it. Dangit, I LOVE the smell of being RIGHT in the morning.
