This would happen occasionally on my 2013 Energi. I found that switching between floor vents, dash vents, or both a couple times would get the air blowing again. The problem didn’t occur frequently enough for me to bother trying to really fix it.

After a year I still feel heat on 1, but it doesn't seem unbearably hot like it did a year ago when the car was new. I haven't measured it with a thermometer, so maybe I'm just getting more desensitized to it.

This happened to me, too. Turn off the parking sonar to quickly verify if that's what's happening.

It's not standard. You have to enter the special X-Gauge codes. Some of them are listed here on the Energi forum: http://fordcmaxenergiforum.com/topic/1293-scangauge-x-gauges-programming-c-max-ffh/ The only three I ever got to work are the HVB SoC, HVB temperature, and interior temperature, but those are the most interesting ones to me.

I found this graph on power consumption vs. speed. I'm assuming it's for a Model S, since that's what car they're talking about in the text. C-Max would have an even greater percentage of power going into aero drag because it's lighter and less streamlined. http://www.teslamotors.com/goelectric/efficiency

Looks like he has a lot more than 16 data points. I think the OP is graphing the dash computer results for each day, not for each fill up.

The trouble is there may be more than one problem, and they may not be electrical problems per se, but rather firmware problems. When you have enough lines of code, software becomes so complex that for practical purposes, problems magically come and go with the tide. I have a smartphone app that logs battery voltage and temperature, and my phone went for 11 months with very little background power consumption. Then a few weeks ago I saw the battery was almost dead and something had been pulling a lot of current. The battery usage screen just said "Android System". I restarted the phone and it hasn't happened since - it came and went with the tide. Some app got in a bad state where it was trying to phone home and load ads or something, but to figure out which app would require some debug tools to log what had been accessing the system. Even if I'd found the app, it would be difficult or impossible to figure out what made that app go wrong without the people who wrote it. For a more C-Max specific example, on another thread drdiesel found that it was accessing the USB drive while the car was off. But why was it doing that? Does it always do that on all cars? Might it not do it on some cars, and then, like my phone, suddenly decide to start doing it for some reason? What else does it do periodically while the car's not running? That's a firmware problem which would require the people who wrote it to debug all the way back to root cause. The firmware in the computer decides how to charge the 12V battery, and is awake and doing things even when the car is turned off. It has many opportunities to kill the battery even if there's nothing wrong with the wiring or hardware in the car. In theory any software problem can be debugged but sometimes you need the developers and access to the source code and time to run experiments. That's no fun when your car has to stay in the shop.

The cargo space can certainly be a deal breaker, but you don't need a home charger. The 120V charger included with the car will charge it overnight.

Most of the Scangauge codes didn't work for me. The three that did were State of Charge, Battery Temperature, and Inside Temperature. My best guess as to the inside temperature is that it's a sensor somewhere in the back near the battery fans. If you're using A/C to cool the cabin the temperature in the back will lag the temperature in the driver's seat for quite some time. That's how mine behaves.

On the Energi forum someone just posted the results of an online chat with Ford engineers. They said the Energi does indeed have a lower final drive ratio than the hybrid, so it will probably not have much slower acceleration (when using ICE). Of course I haven't seen a drag race between the two yet, so that all theorizing.

The Energi (plug-in) is 7% heavier than the hybrid, so that's roughly how much slower it's acceleration will be. I don't have any trouble with accelerating or passing with mine. The trunk space is considerably smaller with the Energi. I posted some photos on the Energi forum showing how the cargo space is affected and what you might be able to fit in it. http://fordcmaxenergiforum.com/gallery/album/11-viajero/ As for the cost, I find I get about 3 miles per kWh (from the wall). Electric rates vary widely from place to place, by how much you use, and by time of day. You'll have to look at your electric bill and find your specific cost per kWh, then divide by 3 to get cost per mile.

If you have an Energi and are using MyFordMobile, you can go to the web site under My Account->Notifications and tell it to text and/or email you to warn of a low 12V battery.

I've seen different web sites list different results per gallon. It may actually be different from place to place and batch to batch for all I know. Gasoline and diesel are blends of hydrocarbon chains of various lengths. It wouldn't surprise me if the mix was somewhat different from refinery to refinery.

MyFordMobile does this all the time. I can log in to their website and see where my car is on a map, or even start it remotely over the internet. People on these forums have reported using it to track where their car went while in for service at the dealership. When you start driving, it pops up a message on the dashboard screen telling you to warn your passengers they're being tracked. If I can log in and tell their servers to get this information from the car, then their system administrators could certainly do the same without me initiating anything. I have no evidence to say that Ford or the police or the feds or whoever your favorite bogeyman is are actually doing this, but they definitely have the ability to do so. Well, at least as long as you're in range of the cell network it's using.

Depending on which web site you read, diesel fuel gives 11-15% more heat per gallon than gasoline when burned. Plus most gasoline has about 10% ethanol which knocks off another 3% heat content. So, diesel engines are burning (roughly) 14-18% more energy-rich fuel to start with. Then they're a bit more efficient at converting heat to mechanical energy as well. Of course diesels and hybrids are both more expensive than plain old gas cars, so a diesel hybrid would be even more pricey. I think that Volvo's around $60,000 U.S.
