Rob - Thanks for your submittal. Energi data are fine - I plan to separate the Energi data and the Hybrid data. Are there some additional items we should ask about for the Energi? What does "73.5 MPGe. 250 kw" mean on your lifetime mpg line? [i looked at the manual and think the 250kw means you have used 250kwh of electric energy that went into your plug-in battery by plugging it in (charging) and the MPGe divides miles by the sum of your gallons of gas used plus "equivalent" gallons of gas calculated from your kwh usage via the plug-in battery. Is this correct? Do you know if the kwh figure comes from what you charge into your plug-in battery or what you take out of your plug-in battery? Do you know how the equation for converting kwh to equivalent gallons of gas?] Does the ENERGI tell you how many of your EV miles are from the plug-in battery and how many are from the regular hybrid battery? Does the ENERGI get more regen than the HYBRID? Does regen braking on the ENERGI feed the plug-in battery or the regular hybrid battery or both?

I have no idea if that would work and I have no intention of resetting my LIFETIME values so I am not going to try it. I have been using AVG MPG and trip odometer 1 for each tank of gas. I have never reset trip odometer 2 so it gives LIFETIME values to me except that I have noticed that EV miles on the trip odometer only goes up to 999 so my trip odometer 2 says I have only 902 EV miles when I actually have 1,902 EV miles. I am curious about how high the miles can go on the trip odometer - my trip odo 2 says 4,653 no so it can at least go to 9,999. Per page 105 of the owner's manual: Trip Summary and Lifetime Summary: These will be displayed upon shutting off the vehicle. Trip Summary will appear first, then Lifetime Summary will be displayed. You can toggle between these displays using the up and down arrow keys on the left hand steering wheel controls. Trip Summary data is from the last power cycle, while Lifetime Summary data is cumulative from the last Lifetime Summary reset done through the Settings menu in the message center. So to reset the LIFETIME values - use the controls on the left side of the steering wheel and the small screen to the left of the speedometer - select SETTINGS then DISPLAY then LIFETIME SUMMARY then press and hold OK to reset the LIFETIME values.

wamba 2000 - Thanks for the data update. I have a spreadsheet going. Hope we will get data from a bunch more people.

wamba2000 and valkraider - Can you update your submissions to include all the data elements I put in mine?

My data are: 1. Model -Hybrid SEL 2. Lifetime Total Miles Driven - 4653 3. Lifetime EV miles driven - 1902 4. Percentage drive EV to total - 40.9% 5. Lifetime Regen miles - 299 6. Lifetime mpg - 40.2 7. Lifetime brake score - 93% 8. All full lifetime figures - no resets

To have more data to play with, I would still about for lifetime regen miles. I would also ask for lifetime mpg [so we can see how %EV miles and fuel economy (mpg or gal/mile) are related] and lifetime brake score too.

wamba2000 - Thank you for posting these questions. In addition to looking at EV miles as a percentage of total miles, I think it would be interesting (as first suggested by Plus 3 Golfer) to look at percent EV vs mpg AND percent EV vs gal/mi (or liters/km). I was thinking about doing this too and posted some questions related to this in the thread titled "EV mode driving maximizing". In that thread, I noted that one of the screens that comes up on the left when I turn off my car shows lifetime EV miles and lifetime regen miles. Then I asked (and was hoping for feedback on) whether lifetime EV miles is the total lifetime EV miles (i.e., already includes lifetime regen miles) OR whether you need to add lifetime EV miles plus lifetime regen miles to get total lifetime EV miles (i.e., add #3 and #4 in your post to get the total lifetime EV miles). I think lifetime EV miles already is the total (already includes regen miles) and so there is double counting if you add #3 and #4. Page 105 of the owner's manual which says: • Distance - The distance travelled on battery power only (EV distance) and regen distance are displayed. Regen distance is the estimated range gained from energy recaptured through regenerative braking. When energy is taken from the hybrid battery to move the car in EV mode, there is no way for the car to know if that energy went into the battery via regen braking or when the ICE was running. Regen miles (as described on pg 105 of the owner's manual) must be estimated indirectly based on the amount of energy that goes into the hybrid battery from regen braking. Regen miles is shown as a separate figure to show the benefit we are getting from good (regen) braking. When the car is propelled in EV mode (energy is coming out of the battery to move the car) it would be easy for the computer to track the miles and it likely includes partial credit for when the car is propelled by EV and ICE working in tandem. As of a few days ago over 4525 miles, we had 1847 EV miles [40.8%] and 288 regen miles [6.4%] - so I think our total percentage EV miles is 40.8%, not 47.2% [40.8 + 6.4 = 47.2].

Thanks. The "IM" is what was cut off in the photo of the TSB re the software update that may help w some 12v battery issues.

I was thinking about this some more when I was driving this morning. When energy is taken from the hybrid battery to move the car in EV mode, there is no way to know if that energy went into the battery via regen braking or when the ICE was running. This also means that regen miles (as described on pg 105 of the owner's manual) must be estimated indirectly based on the amount of energy that goes into the hybrid battery from regen braking. So my total EV miles are 1847 EV miles [40.8%] - this figure includes approx 288 regen miles [6.4%]. I think the earlier suggestion to collect some data on miles driven, lifetime mpg, lifetime EV miles and lifetime regen miles ws a good idea. I will try to put an organized list of these questions together and post it a new thread.

Thanks, but is it correct to add the two figures [40.8 + 6.4 = 47.2], or is 40.8 the grand total [i.e., the 6.4 is already included in the 40.8]?

I agree, that would be awesome. I'd like a modular version so the total weight of the modules could be more than I would want to pick up at once and even better a battery add-on integrated into an optional donut spare tire.

Double click on the image in Oxnard's post and the image will open in the gallery, then right click on the image in the gallery and you will get image size options. On the large size image, the TSB # is clearly 12-11-8.

One of the screens that comes up on the left when I turn off my car shows lifetime EV miles and lifetime regen miles. Are total lifetime EV miles equal to the lifetime EV miles figure OR to lifetime EV miles plus lifetime regen miles? Over 4525 miles, we have 1847 EV miles [40.8%] and 288 regen miles [6.4%] - so is our total percentage EV miles 40.8% or 47.2% [40.8 + 6.4 = 47.2]? I think the total percentage EV miles is 40.8%, but I'm not sure. I think 40.8% is supported by page 105 of the owner's manual which says: • Distance - The distance travelled on battery power only (EV distance) and regen distance are displayed. Regen distance is the estimated range gained from energy recaptured through regenerative braking.

According to the odometer and lifetime mpg on our SEL, we have used 112.5 gallons of gas. According to our fill-up records we have pumped 112.1 gallons and the car says we have used 4.4 gallons since our last fill-up which totals 116.5 gallons - so our fill-ups are about 4% more than our usage recorded by our car or on average about 0.4 gallons difference on a 10 gallon fill-up.

You're doing great - 44mpg in Roanoke in March is excellent!

Thanks for posting. The end of one line is a bit cut off - what is "4.2 inch FCD" ?

mbedit - I didn't realize you were the originator of this thread. I need to cover my tracks by saying that my C-Max has not yet been to Wilmington or any other Coastal NC location, no further east than Kinston and Greenville.

Maybe the C-Max drafting behind you was pulling so hard that it drafted 1/2 gallon out of your tank.

I would welcome any tips you have on cleaning leather seats. We have a small mark on our passenger seat that looks like it is from some NC red clay. I tried cleaning it off following the mild soap and water instructions in the owners manual. This didn't work. I bought a leather cleaning product, but have not tried it yet. Does the conditioner product help protect against dirt and stains?

>>>It just kills me that Ford does not allow an option for people of warm climates that is not leather.>>> Totally agree - we would have preferred fabric in our SEL, for winter, for summer and for maintenance/cleaning.

I'm still in. You know how to e-mail me to set up a skype time.

That's good enough for you to advance to the next round of the ACC tournament.

Before our C-Max we had a 2000 Honda Insight that required two battery replacements that were covered under warranty. Honda had extended the warranty beyond the time/miles that came with the new vehicle. If you are anywhere near Sanford NC and need a replacement battery, I suggest checking with Taylor Automotive/Re-Involt Technologies - see their website at www.re-involt.com

Peukert constant? I should have known (according to e-how.com) "The Peukert number is a value that represents how efficient a battery can hold a charge. When a Peukert number is close to 1, it means that the battery loses very little charge. The higher the Peukert number, the less efficient the battery is. This value can be calculated using the formula n (Peukert's number) is equal to the logarithm of C (theoretical capacity) divided by T (discharge time) to the base of I (the current)."
