AAA tests show 5-7% city mileage gain with automatic engine stop-start
Looks like the AAA is trying to educate motorists about the benefits of stop/start.
Their study also busts the misconception that stop/start isn't on American cars because the systems don't register enough of a beneift in EPA testing. Quote:
They estimate annual fuel savings of $179 for consumers, based on 15,000 miles a year in a vehicle that averages 20 mpg with fuel prices at $3.65 per gallon. Notably, they also point out the savings "do not include other factors relative to ownership costs of vehicles equipped with automatic stop-start systems, such as potentially higher costs to replace the upgraded battery or starter typically used in these vehicles." |
Do you think AAA will ever do a study on the savings for "manual engine shutoff without coming to a stop," or EOC as we call it here?

I thought we did not have start-stop because Americans would not put up with the injustice of their air conditioning turning off.

Ooh, sorry. I'll have to buy another new car so that I'm not imperiling you guys any more. And the puppies, I've got to stop risking all those puppies' lives.

We mainly don't have start/stop because the EPA testing doesn't reflect any benefit. During the testing, there is no sustained periods where the vehicle is stopped and idling (or not). Its just speed up/down.
The A/C thing can be remedied by a little extra cost. Heat exchanger manufacturers have incorporated phase change material (wax) into the heat exchangers to 'store cold/heat' for a limited amount of time. I think in the article I read it was 30 seconds. The additional cost was pretty minimal. |
Myself and several insight owners see more like a 10% savings with auto stop. :thumbup:

Well, people do not want their AC cutting out, and if they wanted to pay extra for better mileage, they would purchase a hybrid!
For the puppies? Wolves? http://i299.photobucket.com/albums/m...pies/Quiet.jpg Wolf puppies! |
If you had actually driven a hybrid you would know the same applies to the heater. At least some cars like the Civic and prius can run the ac on battery power for a few minutes before the engine needs to refire. :thumbup:
Me? I use recycle for air flow and let off the brake every so often so the engine runs a little, then reapply brake and auto stop restarts. |
