"No projections are needed in the wind tunnel, though, as the Accord has already bettered its performance due to a drop in the coefficient of drag from 0.34 to 0.31. I'd like to know how they accomplished that as the frontal area does appear to be more substantial than the gen 7's. " Keep in mind that the frontal area is seperate from the drag. To get total wind resistance you multiply the two together. I also thought the gen 7 was .30. EZ - you will get 40 eventually. That sixth gear is your secret weapon. Have you tried 0w-20 synthetic yet? Have you tried 40 psi (or the max sidewall - should be 44). Choose the warmest day you can stand without A/C. Check the weather channel to make sure there won't be wind (or you could cheat and look for a tailwind) and I think you can make it. Malmousa - I am very suprised to see a hypermiler getting 25 mpg in the new Accord - what mileage were you getting in previous cars. |

Replying to: dudleyr (Apr 10, 2008 6:03 am) "That sixth gear is your secret weapon" The real issue is the final drive ratio. The final drive in the V6 6 speed coupe is 3.55, and the automatic V6, 4.31. Very strange actually - usually just the opposite because the AT has the advantage of the torque converter multiplier effect and usually has the lower final drive. http://corporate.honda.com/press/article.aspx?id=4102 The 6 speed coupe V6 versus the AT V6 VCM SHOULD give better MPG, unless the VCM really does what it is touted to do. I have my doubts. |

Replying to: dudleyr (Apr 10, 2008 6:03 am) http://www.motortrend.com/roadtests/sedans/112_0802_midsize_sedan_comparison/ They claimed the Cd numbers I quoted. I believe that I've seen .30 for the gen 7 Accord as well. One of the thoughts I have every day as I walk down my driveway after getting the mail and I look at my 08 is Wow! big car! Lots of frontal area, must displace a lot of air moving at hwy speeds. Mileage holding steady  21mpg over 6,000 miles and 90% city bal hwy(08 EXL-V6). I've got a trip to the White Mts of New Hampshire planned next week and I've already warned my wife that I'm interested in true hwy mileage so I'll be tanking up entering and exiting the interstate to see what I get, will post results.

| To all those getting terrible mileage- Have Hope! My uncle gets right at 29-30 in his '08 EX I4 auto. Mostly slow rural-ish roads, not really around town or highway. And he does not go out of his way to get good gas mileage. I haven't ever gotten the chance to take a long trip in the car, but I have no doubt that I could get over 35mpg on the highway if he gets almost 30 around town-ish. Of note, this is exactly the same mileage he got out of his 6th gen (2000) Accord EX I4 auto. Both Sedans. The car currently has just over 6k on it. | |

Replying to: malmouza (Apr 09, 2008 5:11 am) Don't even bother checking it until you have 4-5000 miles on it. It will get better milege as it breaks in. Even then , why even bother? It'll get whatever it gets!

"Even then , why even bother? It'll get whatever it gets! " Thats what my friends with SUV's used to say. Now it is hysterical to watch them line up for 20 minutes to save less than 3% ($.10 per gallon) on their gas costs. Maybe if they were aware of their mileage and checked more often they would have bought more sensible vehicles. MPG is also a good indicator of the cars overall health. If my car did not get what I wanted I would sell it in a heartbeat. |

Replying to: dpmeersman (Apr 10, 2008 8:57 am) Once in a great while, I'll check my mileage but doing so isn't something I really care about that much. If the car isn't running up to snuff, I'll know it without having to check my mileage. I know people (mostly older people) who keep a detailed log in their glove boxes. They keep track of EVERYTHING. That's not me but, hey, if that makes them happy...
