TCH MPG Drop During Extreme Heat by shook4
Aug 08, 2008 (8:35 am)

We have had tempeture in the mid 100's for the past couple of weeks. I have noticed a 3-4 MPG drop in town driving on our TCH. I think it is because of the battery drain due to the AC, AC blower fan, and all the engine cooling requirements such as the electric radiator fan, water pump, etc. I think the battery drain requires the engine to run more often to recharge. I also noticed it was very difficult to rum in total battery mode. Now that the temp is below 100 the gas mileage has returned to normal. Anyone else experience this issue in extreme heat.

Absolutely normal. I live in Phoenix, and have had my TCH for a little over 2 years now.
 
Summer tanks in my car have gone as low as 29 MPG and as high as 40 MPG if most of the trip is highway miles.
 
A little trick:
 
If you know the car is heated up and the battery charge is good and you are below 42 miles per hour, just turn off the A/C button for a few seconds and the car will sometimes go to electric mode. After all the cold air has blown out of the vent system and the car is in "E-Mode" just turn the A/C button back on. In some cases the car will remain in E-Mode and other times it will go back to gasoline.
 
I have used that method dozens of times to get a little more "battery time."

The battery capacity drops at high temperatures, reducing the amount of time one can run on battery even more. Long trips with the air conditioning on will reduce the battery temperature and improve mileage. I just consider either temperature extreme to be bad on mileage.

Live in phoenix as well...and yes the MPG drop when the temp is over 100 is about 3-5 mpg. I notice that the battery drains faster mostly because the a/c is running at full capacity....but I can't complain....after sitting outside in 115 degrees for 5 hours in full sun with only a front sunshield the a/c cooled the car down rather quickly. Still the lowest tank I've recorded is 33.1 and that was the hottest week here with temp highs over 112 all week and was forced to keep the car outside during the day.

Just for clarification, are you saying that you are getting 33 mpg even with 112 degree weather? My hybrid is coming in on monday, unfortunately it is in black color and in the valley where I live, it is 100 degrees for couple months.

Yes 33.1 is the lowest tank I've recorded.....usually its about 50% city 50 % highway. This week its been very humid and around 108 and the mileage is back to 35 even with the a/c working overtime. When I first got the car in Feb was averaging 37-39 mpg per tank but the temp was averaging between 60-90.
Great car....you are going to love it.

Mileage after two tanks by tjackson12336

I commute 120 miles per day. 20% rural hills, 20 % in town and 60% highway. First tank was 40.3 mpg. Second tank 42.1 mpg. I typically am driving the speed limit or just a few miles over. So far so good. Great mileage for this large of car.

effects of ethanol? by sunkist2

I have had my 09 TCH for two months with just under 2000 miles and the mpg has been around 36-38 running the A/C. The last tank is showing 42.8 without running the A/C so a big improvement. I use 100% gas (no ethanol) and am curious if the E10 stuff hurts the mpg. I also have a 96 Camry that typically gets 31mpg on 100% gas and when we tried E10 the car ran lousy and the mpg dropped to 28-29. Will E10 have the same effect on the TCH? E10 in the OKC area seems to be predominate now and it is getting harder to find 100% gas. I am hesitant to try E10 if it will hurt the mpg (even if it is a few cents cheaper), not to mention what other "bad" things E10 might do to a car.

I have 09 TCH bought in May--used normally for in town driving--stops/starts and lights and since I'm in TX run my AC---I normally get a 32-33 avg and the gas I normally put in has ethanol to certain %--there are times we have gone on the road and gotten more like 38-39-40 mpg and bought gas that probably had no ethanol...
so yes--if you have ethanol mix it will lower your MPG no way to avoid that since it is law of chemstry...

The energy content of gasoline is 112-114,000 BTUs (winter/summer blends). Corn ethanol contains 76,000 BTUs. E10 reduces the energy content about 3%.
