I notice on both the driver and passenger windows, the black trim separating the front lower triangular corner of the window and the main window on the outside is popping out at the top. I went to the dealer and saw the same thing on several of their cars in the lot. I push the trim back in the slot, but it pops out again. I gently pounded on it with my fist, and it seems to stay better. I am waiting to here from the dealer if there is a fix for that. I think they need to come up with a better way of attaching the trim.

Fusion Energi vs Honda Accord Plug-in (HV charge mode)
larryh replied to Gyrobob's topic in Batteries & Charging
http://www.autoblog.com/2012/10/03/2014-honda-accord-plug-in-hybrid-first-drive-review/ Did consumer reports review plug-in hybrids recently? According to Honda: There are modes and then there are Drives, and you shouldn't confuse one for the other. The HV mode is similar to the Energi's EV later mode. It attempts to preserve the state of charge of the battery at the current level. You would have to drive the Energi down a large hill to recharge the battery to get a similar effect of the Honda's HV Charge mode. -
I believe that active noise cancellation uses the car's audio system and speakers. So the audio system is always on. The on/off switch for the radio itself is right below the MyFord touch screen on the left.

Fusion Energi vs Honda Accord Plug-in (HV charge mode)
larryh replied to Gyrobob's topic in Batteries & Charging
Reading about the different drive modes for the Honda from http://www.autoblog.com/2012/10/03/2014-honda-accord-plug-in-hybrid-first-drive-review/: EV Drive. Here, the only energy moving the car comes mostly from the battery. When starting with a full battery pack, the engine will not kick in under normal city driving until the pack is depleted, which should take 10-15 miles. When the driver requests "higher speeds or under high demand for acceleration," the gasoline engine will turn on "to provide additional power." This drive operation automatically comes on during deceleration. The official top speed in EV Drive is around 80 miles per hour and an electric A/C compressor and water heater allow the car to stay in EV mode longer.Hybrid Drive: This is where the Accord PHEV does its best Chevrolet Volt impression. The battery is still used, when there's juice, but mostly, Hybrid Drive only gets the engine running in order to send electricity straight to the 124-kW electric traction motor. The engine does not turn the wheels directly.Engine Drive: Now we're in standard internal combustion territory, because this is when the gasoline engine provides direct drive of the wheels. Battery? What battery?So it appears the Honda doesn't turn into a hybrid when the battery is depleted. It either does what the Chevrolet Volt does, uses the gas engine to generate electricity to power the electric motor, or uses the gas engine to drive the wheels without any help from the battery and electric motor the same as a traditional car. The Honda has higher MPGe estimate of 115 and higher MPG of 46, compared to the Energi's 100 and 43. I wonder how it actually compares in real world driving. There should be two MPG ratings for the Honda, one for Hybrid Drive and one for Engine Drive. Which one gets the better MPG? I would think that it would be more efficient to drive the wheels directly with the engine rather than indirectly through the electric motor. I wonder how much less efficient Hybrid Drive is than Engine Drive. HV Charge mode probably relies on using Hybrid Drive. I'm not sure that the above description is accurate for Engine Drive. It must still recharge the battery through regenerative braking or by coasting. Otherwise, that would be a big waste of energy. So it just keeps charging the battery in Engine Drive via regenerative braking waiting for you to switch later to EV Drive or Hybrid Drive when the battery is full? -
Fusion Energi vs Honda Accord Plug-in (HV charge mode)
larryh replied to Gyrobob's topic in Batteries & Charging
I believe the EV range of the Honda is 13 miles. The EV range of the Energi is 21 miles. You should make sure that a 13 mile EV range is adequate for your commutes. -
I think the Energi is very efficient. This is the display from the trip odometer for my trip home today in hybrid mode: It was 92 degrees and I had the air conditioner set to 73 degrees the entire time. When I first started out, the power consumed by the air conditioner was between 4 and 5 kW. It later dropped to less than 1kW for the remainder of the trip. The first 22.5 miles were in EV mode until the battery depleted. I then reset the odometer to measure the mileage for the rest of the trip (I missed the first 0.5 mile of hybrid mode before I finished resetting the trip odometer). The trip was on highways and freeways. There was a lot of traffic so I wasn't able to go the posted speed of 70 mph most of the time. You can determine the average speed for the trip from the display. You have to allow a couple of minutes for stop lights and setting up the camera to take the picture. The clock keeps running even when you are stopped. I wish the console kept track of average speed. I compute the average speed to be around 53 mph. The MPGe for the entire trip, including the miles in EV mode, was 63 MPGe.

Return trip home today. 92 degrees. Air conditioning set to 73. First 22.5 miles were in EV mode until battery depleted. Then reset trip odometer 2 to determine mileage for rest of trip in hybrid mode. -
Reported Trip Energy Used vs Energy required to recharge car
larryh replied to larryh's topic in Lounge - Fusion Energi
Driving on highways/freeways with max speeds ranging between 55 and 60, I generally get around 24.5 miles in EV mode before switching to hybrid mode. However, I do have to slow down at a couple of stop signs and for traffic when entering the downtown area, and there is a mile long moderate downhill segment. But of course, you can't normally achieve the ranges shown above in real driving since you cannot travel at constant speed and level roads with calm winds. (I think you might have a bunch of pretty irate drivers following you going 20 mph on a highway for 43 miles :rant2: ). When you slow down or stop, the regenerative braking system can only capture 75% of the lost kinetic energy. I'm not sure how efficient the generator is in capturing energy while coasting. -
If the console setting is set for MPG, the car will display total miles driven divided by gallons of gasoline consumed by the ICE for those miles (or 999 if no gas was consumed and the ICE did not run). This isn't very useful to display how efficient the car runs in EV mode. If the console set is set for MPGe, the car will display total miles divided by equivalent gallons of gasoline consumed, which includes the energy consumed by the electric motor and the ICE. This shows the overall energy efficiency of the car for both the ICE and the electric motor combined. When running in hybrid mode after the battery has depleted, MPGe and MPG settings should display the same value (provided the level of the hybrid battery did not change from the beginning to the end of the trip(s)). I have my console set to display MPGe. I usually drive in EV mode. So MPG isn't very useful for my trips. You can always recover MPG from MPGe, or MPGe from MPG if you keep track of the distance traveled and the kWh of plug-in energy used by the car (shown by MyFord Mobil). If you want to measure the energy efficiency of the car, I recommend using MPGe. The Energi is much more efficient using electrical energy than using gasoline. If you display MPG, you are missing the energy that the Energi uses most efficiently from the mileage computation. I have measured the actual MPGe for the Energi going 70 mph using gas vs. using plug-in electric energy for two different trips. For gasoline, I achieved 41 MPGe. For plug-in energy, I achieved 75 MPGe. The Energy uses plug-in energy approximately 1.8 times more efficiently than energy from the combustion of gas at 70 mph. MPGe is the only useful metric that we have readily available to make a fair comparison between the Energi fuel efficiency and the fuel efficiency of normal gasoline powered cars. Comparing the MPG of the Energi with the MPG for gasoline powered car is a very unfair comparison, like comparing apples to oranges. But unfortunately, the Energi seems to exaggerate MPGe, sometimes by up to a factor of 1.4 times the correct value (the actual factor depends on the amount of gasoline consumed and the charger used among other things).

Reported Trip Energy Used vs Energy required to recharge car
larryh replied to larryh's topic in Lounge - Fusion Energi
Note that the range estimates posted above are based on the assumption that the same amount of energy can be withdrawn from a fully charged battery regardless of the rate power is drawn from the battery. That may not be correct. I've seen the reported plug-in energy used when the battery is depleted vary from 5.5 to 5.8 kWh. Part of the variation could be explained by the average speed of the trips. -
Reported Trip Energy Used vs Energy required to recharge car
larryh replied to larryh's topic in Lounge - Fusion Energi
I did a simple experiment to further determine the efficiency of the car in EV mode with climate control off. I drove the same stretch of roads, in both directions, for a short distance, with the cruise control set to speeds from 20 mph to 70 mph. I reset a trip odometer at the start of the trip and observed the MPGe at the end. I averaged the results at the same speed going in both directions (the roads were not perfectly level so you get better MPGe in one direction vs. the other). I did this during early morning hours when the winds were calm, temperature around 70, and there was no traffic to interfere. Note is very hard to get consistent results at low speeds. The relationship between speed and MPGe appears to be linear between 20 and 70 mph. Based on MPGe values and the maximum plug-in energy displayed by the console in the Trip Summary/Odometers that I have observed after a depleted battery, 5.8 kWh, the estimated range of the car at the various speeds is computed as (MPGe / 33.705 kWh / gallon equivalent) * 5.8 kWh: Speed (mph) Distance (miles) 20 43.2 30 37.9 40 32.6 50 26.9 60 22.8 70 18.0 The estimates for low speeds are more uncertain than for higher speeds. Of course, the temperature, grades of the roads, wind, and other factors will influence the actual miles achieved for a fully charged battery. The results above seem to be consistent with what I have observed for the car. -

MPGe vs. Speed in EV Mode -
Updated my previous post with the following: The purpose of MPGe is to measure energy efficiency. From the EPA ratings of 100 MPGe and 43 MPG, that informs you using electricity is 2.3 times more efficient that burning gas. Much of the energy burning gas is wasted. Only about 1/3 of the energy released from the combustion of gas is actually used to propel the vehicle. Electricity is 72% efficient, 72% of the electrical energy put into the car is used to propel the vehicle. So MPGe gives you the overall energy efficiency of operating the car. How much of the available energy you supplied to the car was actually used to propel the vehicle. Note the energy expended extracting, refining, and delivering the gas to the gas station is not included in the EPA MPGe estimates. Similarly, the energy required to generate and transport electricity to your wall outlet is not included. If you are interested in the operating cost for the vehicle, the window sticker also provides the estimated annual costs to fuel the vehicle with electricity and gas.

Yes, the ICE did have to work harder, at times, to charge the battery in addition to propelling the car. And yes, some of the kinetic energy of the car was skimmed off and stored in the battery during coasting (the ICE is going to have to provide the power to bring the car back up to speed and restore the kinetic energy that was skimmed off) . And yes, when stopping, regenerative braking captured much of the kinetic energy from the moving car and stored it in the battery, rather than wasting it as heat energy which occurs with normal friction brakes. But it was the ICE that provided the power to get the car moving and keep it moving, and hence supplied the kinetic energy that is being captured by the battery. These are the principles that give a hybrid much better mileage. It doesn't waste as much energy as a normal gasoline powered engine. It captures the energy that would otherwise be wasted and stores it in the battery for later use. There is no way to know what the ICE would get if there were no battery. In any case, it was optimized to work in conjunction with a battery and probably give poor results without one. If you coupled a normal gasoline engine with a battery, you would probably get much worse results than the Energi. The purpose of MPGe is to measure energy efficiency. From the EPA ratings of 100 MPGe and 43 MPG, that informs you using electricity is 2.3 times more efficient that burning gas. Much of the energy burning gas is wasted. Only about 1/3 of the energy released from the combustion of gas is actually used to propel the vehicle. Electricity is 72% efficient, 72% of the electrical energy put into the car is used to propel the vehicle. So MPGe gives you the overall energy efficiency of operating the car.

Similarly, the energy required to generate and transport electricity to the wall outlet is not included. If you are interested in the operating cost for the vehicle, the window sticker also provides the estimated annual costs to fuel the vehicle with electricity and gas. I don't think the Chevy Volt is all that different from the Energi. It also uses regenerative braking to get its EPA rating. You would have to actually compare the mileage of the Volt after the battery has depleted with that of the Energi to claim one is more efficient than the other. The EPA claims that the Energi is more efficient.

The ICE charged the battery. So it consumed fuel to charge the battery. The EV miles resulted when this energy was reclaimed from the battery. Your actual MPG is 40.3 as shown. No plug-in energy from the wall was used to power the car. Actually, it would be better to display MPGe. That would take into account any difference between the battery charge level before and after the trip. That would guarantee that you did not use any energy generated during the previous trip and you do not have an residual energy generated during this trip that you didn't use. But the difference should be minimal for this many miles. You have almost 7 hours for the trip, but only 187 miles. The average speed is 27.7 mph. Were you doing a lot of city driving?
-
You only traveled 187.7 miles. Of those miles, 84.4 were with the ICE off.

I experimented with the coach display briefly this afternoon. It seemed to me that cruising score is based on average speed. If I go around 30 mph, the score converges near 100. If I average 55 mph, the score converges to around 75, or something like that. It doesn't appear to have a long history, i.e. quickly forgets previous speeds. Since speeds correlate with power, it could also be based on the average power that you have been using. So if you go down a hill and charge the battery, your cruising score should also increase. Similarly, the acceleration score converges near 100 as long as you keep the power levels low (something like within the first two marks of the power display). The score quickly falls when power levels increase (i.e. when power exceeds somewhere around the first two marks). So I wonder if you maintain a steady speed for a long time (and don't go too fast), the score eventually converges to 100.
-
Yes, the posted speed limits on all streets and roads on my routes are at least 55 mph (except for the 0.4 miles for the street that I live on). Unfortunately, there are no pedestrian signals at the stop lights on my route to give an early warning. Many of the signals change immediately when someone approaches the intersection from the cross street at times and not at other times. They need to have more predictability.
-
Looking through my driving scores, they are mostly in the 80s with one 90, all with brake scores in the upper 90s. However, there are two in the 70s, and both of them had lower brake scores around 85. It is hard to get good braking scores when the posted speed limit is 55 with stop lights. The stop lights don't provide adequate warning before turning, forcing you to stop quickly. They need to come up with more eco friendly stop lights.
