EPA Revised MPG - Hybrids The Big Losers quote- Hybrids will be the big losers, however, with the new EPA testing. Hybrids like the Prius and Civic Hybrid will see their city ratings drop by 20% to 30% in the city and 10% to 20% on the highway. -end |

Replying to: moparbad (Dec 13, 2006 6:10 pm) Aha.. Gotcha.. Look at this nonsensical anomaly ... In their article about the subject the San Jose Mercury did some estimates of what the new ratings might be> Prius 2007 .. 60 / 51 / 55 Combined Prius 2008 .. 45 / 43 / 44 Combined Fusion 2007 .. 23 / 31 / 27 Combined Fusion 2008 .. 20 / 28.5 / 24 Combined Nothing special here, yet. But on a Fuel Usage basis: Prius 2007 at a 55 mpg Avg: a driver uses 18.2 gal/1000 mi driven Fusion 2007 at a 27 mpg Avg: a driver uses 37.0 gal/1000 mi driven According to the EPA the 2007 Prius should be 18.8 gal more efficient than the 2007 Fusion for every 1000 mi driven. 2008 Prius at a 44 mpg Avg: a driver uses 22.7 gal/1000 mi driven 2008 Fusion at a 24 mpg Avg: a driver uses 41.7 gal/1000 mi driven Therefore: According to the NEW EPA estimates the 2008 Prius should be 19.0 gal more efficient than the 2008 Fusion for every 1000 mi driven. But as you know nothing has changed at all. None of the vehicles on the road are any different this week than last week and none of the new vehicles to be sold are any different than the ones already sold. It's just that now the EPA can rest for another 30 years without the public hounding them about 'These estimates are bogus' ... and a lot of drivers in all kinds of makes are going to exceed the EPA estimates by a lot, maybe 10-30%. I personally will exceed the new EPA estimates by 5-15% depending on the weather and other conditions. |

Replying to: moparbad (Dec 13, 2006 6:10 pm) The new TCH came out this year after the EPA had made it's proposal to the public back in January. Normally this kind of change is first given to industry so that it can plan how best to implement the new changes - let's say sometime last year. The Prius EPA's are 60 City and 51 Hwy .. a 17.6% difference The HH EPA's are 32 City and 27 Hwy .. a 18.5% difference The TCH EPA's are 40 City and 38 Hwy .. a 5% difference The HSD system is the same, why wouldn't the % difference be the same on the TCH? In addition, from initial reports most people can regularly attain the OLD EPA's in the new TCH with little difficulty. I believe that Toyota implemented the new EPA regs for the TCH on its initial launch. Therefore for this key vehicle it may result in a very small change or no change at all when the new ratings are posted.

Replying to: tpe (Dec 14, 2006 5:42 am) The Hybrid advantage, fuel-wise, is about 35-45%, as they have a tendency to train drivers, by their displays, to drive more efficiently. My use of the term "double" wasn't meant to be technically correct (it was just a post to make a point about savings being savings) and it was indeed the wrong word to use. It doesn't invalidate the point I was making, however. Often times I am mistaken in expecting others not to be so totally literal in examining each and every post, for a flaw to point out. That expectation is unreasonable, as some people are just that way, totally literal about everything. That is my bad.

Replying to: terry92270 (Dec 14, 2006 3:06 pm) The belief that hybrids train drivers to operate their vehicles more efficiently is valid. There are a lot of people advocating this type of instantaneous fuel consumption gauge be put into all vehicles as an effective, relatively cheap way to reduce consumption. I believe it would work.

Replying to: tpe (Dec 14, 2006 3:37 pm) Some things it's taught me... Drive on local streets as often as possible in my Prius Drive on the highway as often as possible in the Highlander. Heavy rain reduces fuel economy about 15%. Strong headwinds reduce fuel economy about 10%. The winter driving penalty is 8-12% Short trips kill fuel economy by nearly 40%

The winter driving penalty is 8-12% Short trips kill fuel economy by nearly 40%" Man I hope those aren't cumulative. Driving in heavy rain with a headwind in the winter on a short trip would be a reduction of 72%!
