What's your long term fuel economy

[lolder]

Glad to hear your new FFH is doing well. I'm in Arkansas visiting relatives. The 10 mile drive to town over rural roads at speeds up to 60 usually yields over 40 mpg. We were late yesterday and I pushed it with stronger acceleration and braking and saved about a minute off the 15 minute time with a top speed still at 60. I got 30.5 MPG !!!!!

[carltj]

Just passed my first 1000 miles in my MMH 502A. Getting a little over 44mpg cumulative average with 20% Interstate driving and the rest about town and secondary roads. I bought it at 174 miles and cum. average of around 30 mpg. I've been very light on the AC and working at hypermileing. With some judicious drafting and speeds of 55-62 mph, I was able to get 46 mpg on I 95, taking my wife to the airport in Providence yesterday. Without careful attention to technique I suspect I would be averaging in the high 30's. With many of my trips under 5 miles, I expect drastic fall off in mpg next winter. Just loving my soon to be orphaned Mercury.

I hate to ask this question but I've missed something in the OM. When I fill up and I zero the MPG it changes in the top right and bottom left of the display. Where is the long term mileage displayed??? TIA

You all talk about long term mileage, someone has to know where it is displayed on the dash, right? Maybe you aren't cancelling the reading after a fill up?

The Long Term Fuel Economy is displayed on the right side of the dash after shutdown at the bottom of the Trip Summary. It is reset by pressing Setup, Resets and Long Term Fuel Economy. You have to hold the reset for two seconds

Thanks, found it. My wife does the driving and neither one of us had noticed it.

Greetings All!

 

I commute 240 miles each way once a week and drive 70 miles round trip each day to work (roughly 2,000 miles each month). I drive about 75% freeway. I've found that using 45 mph roads maximizes the mileage (45+), and I actually don't mind freeway traffic jams, cause the mileage goes way up then too. After 18,700 miles long term avarage is 39.5! :happy feet:

 

Loving the FFH. Yahoo!

[black70bird]

Over at Insideline.com they show a FFH with best/worst/average MPG of 36.6/18.3/31.3 (for them month of February). I wouldn't think it even possible to get as poor MPG as 18.3.

 

Stick your foot in it hard, like a 16 year old male, and see what happens to your mileage! Not that I have tired it or anything. :hysterical:

 

I have long term mileage of 39.8 after 8500 miles and a 3 month stint on 16" snow tires. :shift:

I posted this in the other thread but I'll post it up here too...

 

After owning my Fusion Hybrid for over a year now according to the car I'm at 48.3MPG, which is about right given the summer weather etc. My last 3 tanks doing the math(miles divided by gallons) myself were 49.88mpg, 50.56mpg and 48.7mpg.

 

Usually driving to work with cruise control on the freeway going about 60-65mpg will net me 48mpg to 55mpg depending on wind speed, traffic etc.

 

Best highway trip all time was a 90 mile trip a few weeks ago, 56.7mpg

 

Best city driving >5miles was back in May, managed 72.4MPG(!!!!!!) over 27 miles of driving.

I guess I'm not as easy on the pedal as most of you, I really try to be gentle on the pedal, most of the time. My mileage is good, but I'm only getting (39). I just don't see how so many people report mileage at 49-50. I'm jealous!

I drive a mix of roads with a light foot just shy of hypermiling and at 15,000 miles I'm at 39.0 in S. Florida. On an inter-town trip of 15 miles one way at no more than 55 mph and probably an average of 40 mph I usually get about 45 mpg. Your average trip length and speed have a huge effect. Longer and slower = more mpg.

I have a friend who is claiming that he avaerages about 48 mpg in his FFH. He does about 40% city and 60% highway. 48 mpg sounds a bit high. Is anyone getting close to that number?

Frank-

 

I posted a few posts up that I'm at 48.3MPG. And thats my long term average. I can regularly maintain 50+mpg in all city driving. As it stands right now I do 60% highway 40%city.

 

It takes a light foot on the throttle, and learning really good throttle manipulation and learning how the car reacts depending on driving conditions etc. Coasting for extended periods(pulse and glide in hypermiling terms) Not using climate control unless you really have to. My tires are pumped to a higher PSI as well. Lots and lots of little things that all add up over time.

[cchaos]

My highest mileage was 65 mpg over about 12 miles.

 

My long-term fuel economy isn't nearly that good (38.5mpg). Over the winter, I made some road trips where I had to drive hours against strong winter headwinds and had fuel economy in the low 30's, so that dragged down the average. I also do a good amount of short-trip and stop-and-go driving that negatively affects the mileage, since I live in a warm semi-urban environment, where you catch a series of red lights. It's not so bad when it's cooler and I can often drive on the electric motor, but on a hot sunny day with the AC turned on, the ICE kicks in just to move from one light to the next.

 

What's interesting to me is the effect the car's own temperature has on fuel economy. Now that it's summer, I find that if I leave my car parked in the garage, my fuel economy is considerably better (mid-40mpg) than if I leave it parked out in the driveway, which gets full sun (mid-30mpg). Needless to say, I try to park in shady spots as much as possible and watch the effect on fuel economy.

I want to post real gas mileage data that I have collected on our MMH since taking delivery in September of 09. I have tracked every tank of gas on an I-Phone app. It is 5.2 miles to work all of which is in-town driving. I would guess that about 40% of our miles are on the highway. The app also graphs the gas usage and I have found that the graph matches the temperature with low mileage equal to low temperature. Our long term mileage is 31.98. Yes, I have many runs with 40, 50, 60 and even 70mpg but for every good run there are more 20 to 30mpg runs.

 

We could not be happier with our MMH. We may be replacing our Camry so I have been checking out the MKZH on the Lincoln site. Sorry to see Mercury die. We dislike the FF nose so it has to be a Lincoln. We aren’t sure we can handle the extra $$ for the Lincoln.

 

Those that are claiming such high mileage, their cars must always be warmed up, they must live in Florida but don’t need an AC, and no matter where they go it is downhill. If they are truly driving they way they describe I am glad I am not following them.

Your winter figures certainly reflect this years cold weather. I see that the two entries before the last one averaged about 40 mpg which reflect the summer temperatures. If you leave the heater off in the winter until the green comes on for other reasons, you might improve the mileage there for only a small additional delay in cabin heat. Most of us didn't realize how MUCH MORE even our non-hybrids burned in the winter. The temperature effect seems to be about -0.2 mpg/ degree F. If you had an average of 9 deg. F. in Kansas in Jan., that would be 50 deg. colder than standard temperature of 59 deg. or -10 mpg!

It's interesting to read all the mileage listings folks have posted. Unfortunately from my perspective, true long term mileage is really only calculated over the long haul with multiple tankfuls and total mileage between them. Using the trip numbers that get displayed on the upper left of the dash are overly generous. I remember one short trip I took after the car was warmed up, from the local market to my home, about 1,2 miles, and the reading was 98mpg! Even long term mileage tends to track a bit higher than actual mpg. Mine shows 38.4 yet whenever I've filled up the tank the best I've gotten was 38.7 and the worst was 35.9. So I can honestly say my FFH has consistently gotten no less than 36mpg. Most of my driving is city type with not a lot of long highway mileage. On the few trips I took I did notice that i could get much better mileage than around the town.

 

Am I satisfied with my FFH? Absolutely. My old Buick LeSabre got 18 mpg around town and 26 on the highway. The FFH clearly doubles that number.

Today I filled up, 41.3 MPG (distance divided by gallons) not bad ! (car computer showed 41.6)

Edited July 10, 2010 by rfruth

[philw1776]

Just over 1,200 miles with a long term avg @41.3 driving in New England summer heat wave with AC on but not max. I'm carefull with the pedal and guage searching for glide and maintain opportunities but I don't see how folks AVERAGE in the high 40s.

[lolder]

It's very much a factor of how the car is used. If you drive about 5 or 10 miles at speeds below 50 mph. in moderate temperatures that don't require heating or AC all the time you can get mileage like that. I estimate, however that the average on this forum is very close to the 39 mpg that the car is rated at. I just drove downtown 2 miles at 30 mph and back in 86 deg. temps with the windows open and AC off. Mpg. was 55! My long term average is 39.3 mpg. In that few minute drive, the AC would not have made the car appreciably more comfortable over the open windows. I parked in the shade with a window open. (small town). I'm not obsessive about it and use the AC A LOT in SW FL. The difference between 40 mpg. and 50 mpg. in a short trip is ONE! goose of the accelerator. It is easy to drive and get low 30's mpg. You can also get high 40's. A lot of the difference is your choice. We didn't used to have the choice.

[mikenmar]

Over the course of almost 10k miles, I'm getting about 37 mpg on average. I'm in the SF Bay Area, where the weather is mild, but the ethanol is ever present. Also, my commute to work is less than 3 miles, which also puts a hit on the mpg (but more importantly, decreases overall gas consumption).

[joeyc1960]

My long term avg. is 38 mpg.. But i am using the a/c alot now and my avg. dropped to about 35 ..

[Noel]

42.4mpg is my long term. My car has 15,300m on it. I drive smart to save fuel, but I really question hypermiling techniques. I don't so much question the people who report 58mpg in their FFH, but I very much question the applicability of this sort of driving. I run with 44psi in my tires, practice smart use of the technology (I know I'm being vague, but I know I am applying many many smart principles, and well), have an empty trunk, and live in a warm climate, generally speaking. To use pulse and glide maximally, with this car, would seriously diminish the possibility of routes to take, speed to drive (I hear 25-45mph is pretty much the sweet spot for those mileage figures). I think in order to achieve those numbers, you would be driving a very heavy vehicle in a way that seriously under utilizes the power/convenience it was designed to run at (hey 196hp w/ electric assist). Put another way, if I am going to travel on very low trafficked roads, so as not to slow down traffic too much, and travel at 25-45mph, I might as well own a little electric utility vehicle and get 100mpg. This is my current opinion, and it is based on limited knowledge, but I have a sense now of what it would take, and it's just not worth it to me, and further as I say it's kinda silly, driving around all that car for those speeds. Hey, if it floats your boat, that's fine too.

My lifetime MPG just hit 40.00! Bought the car late last August and have driven a little over 13k miles. I've actually been averaging around 50 for most of this spring and summer, but it took a while for the mpg to recover from a brutal winter which took me down to the low 30s.

 

Here's my tips on how to get your average up. The first few apply to any car:

 

1. Slow and steady speed saves gas. This car can easily average over 40mpg at 65mph if you use you cruise control. Anything faster than 65 and mpg starts to diminish rapidly.

 

2. Keep tires properly (or slightly over) inflated.

 

3. Don't carry around unnecessary weight (your wife, stuff in the trunk, your wife in the trunk, etc.)

 

4. Anticipate traffic and stoplights. Don't waste gas accelerating towards a light that is going to be red when you get there. Coming to a stop and then accelerating back to speed kills mpg, so try to slow down ahead of a red light so that it turns green by the time you get there.

 

5. Use the heater & AC as little as possible. Crack your window and try to park in the shade to keep a cooler interior while parked. Put your windows down as you pull out of a hot parking lot to get some air circulating before you turn on the AC. Then put your windows up because drag kills mpg. Keep the AC on low speed, and don't set it below 68.

 

6. Maximize your regenerative braking. If you know you're going to have to stop, apply the brake softly and gradually to extend the recharging of the battery. Slamming on your brakes and stopping suddenly will not recharge your battery as much as a longer application of the brakes.

 

7. Don't waste your battery driving 45mph! I know the car can do it, but it will ding your mpg because you diminish the battery faster. If you need to drive that fast, bump it up to 48mph, which will kick on the engine. At this speed, the engine will still generally run at over 40mpg and it will charge the battery at the same time! Knowing how and when to use the engine is the key to good mpg. When driving on battery, don't exceed 40mph.

 

But the most important rule is, don't be the annoying hybrid driver that jams up traffic because you're "hypermiling." Those are Prius drivers, and most non-Prius drivers hate Prius drivers. If you really want to save the planet by consuming less fuel, then (1) don't buy a new car, you hypocrite (2) don't buy a new car shipped from Japan, you hypocrite, (3) ride a freaking bike or a bus, you hypocrite, and (4) get out of my way (hypocrite)!
