#1493 of 1583 Decrease in Gas Mileage by supercub43 Jan 28, 2008 (5:45 pm)
I have about 18,000 miles on my 07 Escape 2wd Hybrid that I purchased last April. During the summer thru early fall I was getting 36mpg......but since then the mileage has dropped off to 33mpg. I'm driving the same, driving the same routes to work etc.......the only thing that has changed is the weather......it's cooler now.......I live in central Ca.....has anyone else noticed a change possibly due to temperature change? Or is something else happening. Yes, I've check tire pressure. Thanks Brian

This is normal for colder temps. The colder the air the more dense the air. The fuel control computer mixes air with gas at the same ratio. So, if it works properly, the increase in gas consumption should be considered normal. Ask any pilot who flies a normally asperated engine. Replies to this message: johndix60 (Jan 29, 2008 6:09 am)

Replying to: carysbluesky (Jan 28, 2008 8:23 pm) Pilots will also comment that the aerodynamic drag on a vehicle is, among other factors a function of the square of the vehicle velocity and the density of the air. Colder air equals higher density air and hence higher drag for any given speed.

You must be a CFI; and, you put it well. Keep the Blue side up...unless you're part of an airshow. Replies to this message: johndix60 (Jan 29, 2008 6:28 pm) carysbluesky (Jan 29, 2008 6:41 pm) supercub43 (Jan 29, 2008 7:57 pm)

Replying to: carysbluesky (Jan 29, 2008 11:13 am) CFI-yes, and an engineering test pilot at a major helicopter company for 39 years. We used to say: " keep the greasy side down" !! Replies to this message: carysbluesky (Jan 29, 2008 6:41 pm) supercub43 (Jan 29, 2008 7:57 pm)

Replying to: johndix60 (Jan 29, 2008 6:28 pm) Started in the OH-23 myself (Ft. Wolters 69-41) Retired in 99 and familiar with greasing the skids, especially when flying a loaded UH-1C. Just retired from the FAA myself w/30 years. In any case, I believe our FEH driver now knows all about why his fuel consumption goes up in cold Wx. Not even mentioning the additional drag if he doesn't remove the snow prior to departure. Take care. Replies to this message: supercub43 (Jan 29, 2008 7:57 pm)

Replying to: carysbluesky (Jan 29, 2008 6:41 pm) That's what I figured, but I didn't think it would make that much difference, what with all the computers/electronic on the newer cars, which I haven't seen to many on cont or lycs with........just plain ole Mags and carbs or maybe fuel injected. Oh ya, I've only been a CFII, MEI, BGI, AGI, ATP, SEL, MEL, SES......and 135 Chief Pilot for about 33 years. I do appreciate the input. Will be interesting when the warmer weather comes around to see if the mpg returns to the 36 range. Thanks again   PS........check my name out and that well give you a hint of the airplane I own too.

Replying to: mecheng1 (Dec 04, 2007 7:56 am) The 05 thru 07 AWD Hybrid models do not have a light on the dash that indicates power going to the rear wheels.
#1501 of 1583 Re: Hybrid revs. [mschmal] by wisill Mar 08, 2008 (6:29 pm)
Replying to: mschmal (Dec 06, 2007 6:45 am) Mark, the hybrid engine does not "rev" up to heat the cat converter. The cat converter quickly heats up to normal temperature within 30 seconds. I have a Scangauge II unit that demonstrates this.   The hybrid engine does not "rev" up to heat the hybrid battery. There is a heating element inside the hybrid battery pack.   The hybrid engine does not "rev" up while the vehicle is undergoing braking regeneration unless it's state of charge (SoC) is full and this is a topic by itself.   The "rev-up" of the engine is due to the electronic continous variable transmission (eCVT). Hybrid owners learn to "fake shift" (temporary lessen pressure on the gas pedal) to lower the RPMs and to improve fuel efficiency.

Replying to: keegs54 (Dec 26, 2007 1:54 pm) The 2008 Ford Escape Hybrid is sold out. You can start ordering the 2009 models with the new engine and other enhancements sometime in April 2008.
