Just make absolutely sure that you're in a car that WILL NOT STALL while coasting. My stickshift Toyotas will idle happily until The End Of Time, but I've encountered some SUV type cars with automatic transmissions that will not idle reliably and are not safe to coast. |

You know, the difference between 41 and 38 MPG is not really that much. The creature comfort of cruise control and AC make it well worth the 3 or 4 MPG that these luxuries cost me.

Yeah, I've said the same thing. I'm using them and taking what I get. I drive reasonably, but I don't do real "hypermiling."

YMMV. I will get out and push for 3 extra MPG. ;)

AC isn't really a creature comfort here...it's life support!

I'd still run my AC even if it dropped FE by 25%.
If the cabin temp is above about 72 degrees, I run the AC. |

So what was said above is that if on my two best tanks I hadn't run the AC I'd have gotten about 50mpg? How much energy does it really require to run the AC? 1hp? 2hp? I doubt more than that, so I should probably see a mere 1 to 2% increase in fuel mileage if I turn it off. Thinking back though, my best mileage is with the air conditioner turned on, maybe it's because the fuel atomizes better in hotter weather? Maybe it's because I changed the engine air filter? It certainly has nothing to do with the AC.
Does the Yaris require the full power of it's engine to keep moving? Is it possible that the AC operates on extra power that would otherwise be wasted and therefore only affects your fuel efficiency when accelerating or driving very very fast? |

And no, the A/C doesn't run on magical "extra energy." Just about every ounce of wasted energy has been engineered out of modern highly fuel efficient cars. |

I never drive with the windows open, and except for the last two tanks of gas because of a road trip all my driving is city driving.

Probably around 35 MPH is a break even point between having the windows open and having AC on. Above that I always close the windows and use the AC as needed. Window drag varies a great deal with the wind conditions, of course. Once I've spent the energy to cool off a hot interior with the AC, I'm unlikely to roll the windows back down. Keeping the AC on low recirculating doesn't take a lot of power.

In fact, with the SGII it is nigh impossible to read the drag hit of having the windows down, but turning on the a/c at any speed is an instant large and sustained hit to FE.

http://green.autoblog.com/2007/08/29...-down-episode/ According to the website, windows down does hurt mileage. Just on a simple physics level, the air entering the cabin has to have some breaking action on the vehicle as the air has no place to displace. If you had the tail open, it could be a flow through action that might not effect the velocity of the car. I am no expert on the matter....but I did stay at a Holiday Inn Express last night and will use my AC....because I love cold air and I am rich enough to afford the extra quarter.

As for the test environment, etc., it simply doesn't matter. Windows down in any scenario is far, far more efficient than using a/c in any scenario. It doesn't matter if you're pulling into your driveway or cruising down a highway, rain or shine, winds or no. Tinting goes a long way for avoiding a/c use. When combined with window vents it lets me keep the 35% front window on the sunny side cracked about 2 inches and have the shaded window fully down, or both windows down when the sun is directly overhead or to the front. Aided by the 6% tint on the rear windows and top of the windshield (the darkest allowed by local laws) it helps keep the interior much cooler than without any of these things. In stifling heat I run the fan (just the fan - no a/c) on the fresh intake setting to aid with circulation. Despite living in a high desert region the only times I have ever run the a/c is when my wife experiences hormonal issues. None of my other passengers ever ask for it.
