Replying to: stevedebi (Feb 24, 2005 12:33 pm) I'm hoping he comes back and provides explanation, because he stated that the PSI on the tire represented an "absolute maximum"... The pressure on the side wall is the aboslute max, as it was explained to me. Just like some argue that it would be difficult for a tire manufacturer to figure out how hot your tires gets, it is also difficult to figure out how cold your tire gets. Someone in Alaska would have his/her cold tire at -40°F, while someone in Florida has his/her tire at 60°F and think it is cold. STP (Standard Temperautre and Pressure) is 25°C at 760 mm Hg (or whatever is at the sea level, 1 atm?) No one ever gets that. If the door jamb on my Civic states to inflate to 32 pSi, and the sidewall reads "42 max psi," it makes sence, as the car and tire manufacturers want to build in some room for expansion before your tires go "Kaboom" Maxing out your tire inflation is not the best way to gain mpg's IMHO. Optimizing the tire inflation is probably safer that just plainly going to the max. |

" If it were truly that much superior, they would have disengaged the transmission via computer control" Yes, this was overlooked, or may have saved manufacturing costs with more parts (Another clutch, etc) As you're rolling down hill in gear you can add just enough gas for the engine to overcome its internal friction. If the angle of the hill isn't enough for what you need to do your FCD will move off of 120. Why? Because you're feeding it gas, and look at the increased RPM: it is faster than idle speed. You also need to feed gas to stop the IMA from activating coasting charging. You can overcome this friction by switching to N or depressing the clutch. (Same thing) Now you're not feeding it any gas at all. It's only idling. And the FCD is pegged. In gear=feed gas to overcome internal friction & coasting charging. Out of gear=feed no gas. Gravity is free to propell you. Not rocket science. |

Okay, I am been doing some research on driving techniques with Honda Civic Hybrid and the most controversial one is that of coasting in neutral and then shifting back into drive. From what I hear on forums, this is what a lot of HCH drivers do to gain more mileage, but from other sources, I hear that doing this switch from D to N and N to D will eventually ruin your transmission. How much of this is true?

Just purchased 2005 civic hybrid. I drive to and from work, about 35 miles each way. To work, my drive is downhill. My drive home is mainly uphill. I go from sea level to four thousand feet. Would appreciate any advice for the drive home, uphill. Also any advice in general for a new owner. Thanks

Replying to: gagrice (Mar 22, 2005 12:00 pm) - If you travel at 65mph on your commute, then you should get very good gas mileage. On my trips where I have done this, I have averaged over 50mpg. - When I go 70-75mph, my mileage drops to 45-47mpg. - I have gone on trips with large elevation changes (3-4K feet), and I have sometimes recouped my mileage going downhill, and sometimes not. Same roads. I'm not sure why. Maybe that's why I'm only a mediocre-miler.  If you want to get extreme mileage (some HCH owners average 60mpg), then I say more power too you. If, however, you want to just drive the car and enjoy it, then I've found that the mileage pretty much takes care of itself. My lifetime mileage after 7000 miles is 45mpg and most of that is my short 6-mile commute in city traffic. Last thought: enjoy! It's a fun car to drive, and as a commuter vehicle, it is hard to beat. And based on my experience, your mileage will probably be roughly 25-30% better than you would have gotten with a comparable Honda Civic non-hybrid, under the same conditions. |

From another website: "If you are in bumper to bumper traffic and rolling a long at 5mph, heck yeah, coast all you want, it ain't gonna break anything. You just don't want to be in a habit of rolling at 70mph in neutral down that hill when the deer jumps out and the car on the right swerves into your lane. It is illegal in CA too. Coasting Prohibited 21710. The driver of a motor vehicle when traveling on down grade upon any highway shall not coast with the gears of such vehicle in neutral. http://www.dmv.ca.gov/pubs/vctop/d11/vc21710.htm Note that is it illegal only on highways. I'm sure cities have laws too. The is no way it is ok to neutral coast in San Francisco." |
