Question about "eco" mode by mfreeman1943
Nov 15, 2006 (1:15 pm)
Reply
I've been enjoying my TCH for almost 2 months now. As the weather got colder (Vancouver, BC) my gas consumption has increased. since I drive a lot of short trips, the ICE remains on most of the time.
 
What I seem to notice is that pressing the "eco" button will sometimes cause the ICE to switch off. I'm not using the air conditioning, but I'm wondering if the heat setting without eco keeps the engine on more.
 
Does anyone know (beyond what's in the manual) what the effect of the eco button really is?

I'm wondering if the heat setting without eco keeps the engine on more.
 
I understood from other postings that the ECO setting when using the heat limits the amount of heat pulled away from the ICE for heating the interior, thus keeping the ICE "warmer". As long as you don't get cold leave it on ECO.
 
Perhaps someone more knowledgable can shed some details. I didn't find my car getting hot with the ECO A/C setting this summer so I'm expecting the car to stay warm with the ECO Heat setting.
 
My biggest complaint is when I kick on the defroster, the ECO goes off and then I have to kick it back on when I switch the mode back to the floor or dash.

I am getting concerned with my FE as it seems to be decreasing. I am currently at 29.3 MPG. It has progessively dropped from the first tanks which were around 39 mpg. I am at 3500 miles now. I drive the same routes and same way. I have made many attempts to keep the car in elec mode especially when driving sidestreets to and from work. No luck. The ICE always turns on regardless of speed of acceleration, ECO, no air, no heat no nuthin, etc. I noticed that along with the rumble of the ICE starting i get a double bump in the engine or trans when the ICE engages. This does not seem normal. I started the car up the other day after 3 days off and the engine sounded like a cat was stuck in the fan belt for about 15 seconds. Runs fine now. Although the weather is getting colder here in Illinois I was getting better FE in the summer with the ac blowing all day. Has anyone experienced the same low Fe and any issues with the double bump when the ICE starts?

Well I'm working hard to keep 37 to 38 but no where near as low as you have experienced. I was concerned that I've lost about 2 mpg, but I can't say it's entirely the colder weather. I'm still able on short trips to get 41 to 43 in routes that I got that same mpg during the summer.
 
Tank mpg's may tell you what's happening with the weather, but to really test the car out to see if something's wrong, I'd reset the trip FE on an area where I know what I should be able to do and drive it with a warm engine. If you're still in the 39+ range then there is probably nothing wrong with the car.

MPG Question and Issues by usnlt
Nov 19, 2006 (8:36 am)

When I bought my Camry in July, the mpg started out around 35. It has now dropped to 27. Driving habits havent' changed. My trips average ~4 each way. My best fuel economy is when I've had to drive my car from Arlington to Norfolk, VA. The road trip portion averaged at ~40. Lately, the ICE has been coming on for no apparent reason. It starts with the car, instead of the battery. At stops, it turns on within 10 seconds. The indicator shows a full charge and I can't think of a reason it would be any less than any other hybrid driver. Thoughts? Anyone else experirence something similar where the ICE seems to be running the show?

I have noticed about 2-3MPG drop from 45ishMPG to 42ishMPG due to colder weather, I usually am very gentle with the gas pedal especially every opportunity I get to drive the vehicle below 45MPH to let the E Mode take over... also keep in mind many 2007 TCH owners over inflate the tires (>32psi when cold i.e. 35-40psi) to achieve great MPG, but I do not recommend it for safety reason(s). The 2007 TCH is an awesome Hybrid and I truly am enjoying its quietness every time I drive it, but one must learn how to dive and achieve its optimal performance and great MPG... btw, I keep my tire pressure at manufacturer recommended level (32-33 psi cold).

A few things:
 
1. Are your trips relatively short?
2. What are your outside temps?
3. Have you checked your tire pressure lately?
 
Short trips kill FE because the HSD system does not fully activate until the engine temps are at a certain level. Colder temps makes that time longer. Colder temps also lower your tire pressure, so check your tires.
 
Good luck. My last tank was 36.48, and my average since purchasing my TCH on 6-2-2006 is 36.86 MPG.

My trips are mostly city and short. But they are the exact same trips that I started out getting about 10 mpg better when the car was new. Its not a matter of learning to drive the car as I have not changed my habits from the beginning other than making every effort to keep it in battery mode. I cannot even crawl off the line without the ICE starting. 0 to 5 mph in 100 yards and I am into the ICE. If I do a rolling stop at a sign I can get it to stay in battery for a while but hot or cold the engine runs. The instant Fe drops to about 2 mpg and then crawls op to about 30 at 30 mph. Like I said earlier, hot weather with AC was getting better than the colder weather. Tire pressure is fine. What bothers me is this thing is suppose to get better FE in the city than hwy as the manufacturer states. Not even close in my opinion.

My mileage has definitely dropped since it has gotten colder here. I believe this is similar to the Prius.
 
I think these cars are programmed conservatively. I'm sure if the assist was more active the mileage would improve- but maybe it would shorten battery life?
 
I'm sure once Hybrids start having lithium cells things will improve a bit. We as "early adopters" (although I'm not sure how "early" we really are) are paying to pave the way to a brighter future.

Consumer Reports gives the best realistic numbers for mpg.
It estimates an average 34 mpg for the Camry Hybrid.
I just traded my Prius for a Camry Hyrbid. If I get around 34 for a full size sedan that'll be fine . Consumer Reports gave an average 44mpg for the Prius. Thats about what I averaged. Also, colder weather does decrease MPG. The winter fuel mix in the Midwest is adjusted to burn differently in cold weather. We use a lot of 10% ethanol in the Midwest which is great for saving oil but decreases mpg, too.
