Hi I'm a new Hybrid-er and I must say it's quite amazing; however I am a little disappointed by the mileage (39.9 MPG, 2006 Honda Civic Hybrid) at 3000 miles. I'm just wondering what type of "incubation" period should I expect for full mileage?

Also are there any after-market battery/electic modifications (like for the Prius) for the HCH?


Thanks a lot

As many would suggest to you, the milleage you get is still perfectly OK. But despair not, you came to the right place.

If you spend some time reading though the relevant threads in this forum you'll no doubt gather some valuable tips that will enable you to get great milleage and have lots of fun at the same time.

May I recommend the following excellent article as a good point to start getting the most out of your 2006 Civic Hybrid:

I've heard most say around between 3-15,000 miles.

I myself saw no increase up until around 60,000 but I drive my car EXTREMELY lightly. I can't remember the last time I had her up to 70MPH.

Efficient drivers do it better.
1003 miles a tank personal record. 74MPG calculated. HCH1 CVT

There is no "incubation time" for hybrids. The key to achieving maximum MPG is to drive at the speed where you take advantage of the hybride battery's electric power. For the Toyota Prius this is between 38 and 41 miles per hour on highways.

While there's truth in your statement, Hot_Georgia is also right about the break-in period (at least for Honda Civic Hybrids). From his experience, I would gather that it may indeed be that long - especially if it is driven carefully - as he clearly does.

Unlike the Prius, the Honda's IMAs typically give the gas engine a predominant if not permanent role in moving the vehicle. So changes in fuel economy over a period of time are more evident and measurable.

However, as I mentioned previously, nothing prevents us from applying some techniques to help maximize fuel economy well before completing that break-in.

Cheers

I am not sure if I totally agree. But there are some valid points there.

It's not so much car "break-in" as driver education....Louis

BINGO

I've got less than two tankfuls under my belt on my HCH-II. I get 43 MPG. my drive IS mostly highway. But if you're getting under 40 MPG and it's not heavy stop-n-go traffic all the time - you may not be driving with the best fuel economy in mind. There IS supposedly a SPIKE in MPG anywhere from 3K to 8K miles (from reading on this site), but don't expect that to take you from 40 MPG to 50 MPG. Ain't gonna happen. Maybe 42 or 43 MPG.

I believe we can learn a lot from some of these guys' tips and techniques, but I will probably never achieve the ultra-high FE that some do for several reasons:
(1) I will not use MORE fuel by taking a much LONGER route just so that I can get better MPG numbers. MORE gas used is simply that in my mind - and makes no sense on an everyday basis. As a challenge to see "what's the best I could possibly do" maybe, but not for an everyday drive.
(2) I will not drive 15-20 miles per hour UNDER the speed limit. My time is more valuable, and the "making yourself a nuisance and a danger" factor is too great for me. I try to mostly keep up with the right-hand-side lanes traffic (usually around the speed limit).
(3) I will not coast with the engine off. Safety factor.
(4) I will not drive in the summer without AIR. Texas is just too hot.

If I can get my MPG up to 45-46, I'll be happy.

What's your goal? If it's the EPA rating of 47/49, ask yourself if you ever got the EPA rating from previous vehicles. If not, don't expect it from the HCH, unless you change your driving habits (like I have to as well).

I suspect that folks that drive their HCH's about like regular drivers would(that's me), probably get in the low to mid 40's MPG. So you're in the ball-park.
Welcome aboard! There are a lot of really sharp, motivated, and kind people here. Stick around and you'll see.

STOP terrorism - Drive a HYBRID

Vehicles:
350 miles a week ------------ 2006 HCH II, Magnetic Pearl, w/NAVI (born on May 25, 2006)
350 miles a month ---------- 2003 Mazda Tribute ES-V6
350 miles a year (for now) - 1986 Mercedes 560SL

I agree that the "break-in" of the engine isn't likely to show a significant difference over time. It happens within the first tank. Until recently my 1st tank on my Tacoma was the best tank. Your driving technique should make much more of a difference.

There is also the "break-in" of the new tires. New tires can easily take 8 mpg off your potential mileage for the few thousand miles.
