    Hi John:

    Break-in in today's new cars provides a minimal bump in FE as the tight tolerances are being held until a new cars end of life.

    I am seeing numbers all over the map on this. I see somebody pulled an 80 mpg run in a FE Challenge at one of the various the short leads (best I have done in a TCH was 78 mpg) so there is hope but then I see experiences like CRs posted above. I am not sure what to think? Still working through Torrance to get a 14 Accord Hybrid or PHEV for the week after the LAAS but no luck as of yet.

    Looks like fall (-ing mpg?) is in the air at CR. Maybe the new high compression double catalytic 2.0 can't shut down as much when the weather gets cool.

    Hi All:

    Jesse just finished a back to back with the 14 Accord HEV (45 mpgUS highway) vs. his Third Gen 10 Prius (48 mpgUS highway).

    48 degrees and maybe 10 mph winds. A 15 mile in total RT drive loop on I-295 from Metro Honda in Johnston, RI and back.

    65 mph RT results

    14 Accord HEV: 40.8 mpg indicated. Maybe 41 to 42 mpg actual???
    10 Prius HEV: 49.4 mpg indicated, 46.4 mpg actual.

    Not good results for the Accord Hev . I would have thought better results at 65mph. H

    If that was from a cold start , it's not so bad.

    I would have liked to see better numbers from the Accord.

    Assuming it's running entirely in its mechanical-drive ("engine") mode at that speed, the results should be almost exactly the same as if it had a manual transmission with the same overall ratio. That's respectable but not spectacular mileage for a manual car of its size, so no big surprise.

    I wonder if this was using cruise control ?

    My lowly Civic could equal and maybe beat 42 MPG at 65 MPH.

    Within 10% of a Prius sounds good to me. How would the other midsize hybrids compare in similar conditions?

    One point for the Accord: no BS on the dash display. Still, wouldn't touch it, would want to see how they react to failed batteries, or whatever.

    Hi All:

    The 2014 Accord PHEV w/out a charge is as real as I have ever seen.

    Max push: LAX to San Diego at 82.1 mpgUS displayed. Preliminary estimates not including the map work show 80.049 mpg. That is blistering hot.

    Drove to LA and back yesterday with traffic. 69.1 mpg there and 71.1 mpg for the RT over 220 miles.

    It is real.

    This does sound like a winner to me. Think I will visit Honda sales at Cathedral City today! H

    Hi Harold:

    I do not fault you for considering the 2014 Honda Accord HEV/PHEV. If you can wait a few months, I suspect you will see $3k or more off sticker?

    Now that the 2014 Honda Accord PHEV-13 is gone, it is time to focus on the 2014 Honda Accord HEV.

    2014 Honda Accord PHEV-13 and the 2014 Accord HEV

    Swapping out in Torrance, CA just 2 miles from Honda’s US HQ.​

    To begin, it uses the same tires and drivetrain minus the PHEV capability. To make sure, I checked the distance when driving from a Shell on Torrance Blvd. and the I-110 in Torrance, CA to Marian’s home here in San Diego. The PHEV-13 was found to cover 98.3 miles with 97.5 miles shown from an LAX Shell to the Shell on Leucadia and the I-5. Similarly the Accord HEV covered 97.5 actual miles with 96.4 miles shown. Doing the math on this, the difference was a minuscule 3/1000th. In other words, the two platforms are essentially identical when it comes to the odometer under report.

    2014 Honda Accord HEV

    97.5 mile actual Google Map route.

    Look closely. Over 90 mpg in the heat of battle on the slow rolling I-405 during a typical LA afternoon rush hour.

    80.1 mpg over 96.4 miles displayed = 81.4 mpg after 97.5 actual miles between Torrance and San Diego.​

    First drive conclusions? Given the low 90 mpg result in heavy traffic (saw 94.1 mpg displayed as a high) and the overall 81.4 mpgUS actual result from Torrance to San Diego and a 250' climb near the end of the drive with the EPA of 50/45/47 mpgUS city/highway/combined looks very solid to me vs. the 2013 Ford Hybrids and 13 VW Jetta Hybrid. When I passed the Shell on Leucadia and the I5, the Accord HEV displayed 82.5 mpg or 83.9 mpg actual. This is even higher than the Accord PHEV-13's 80.7 mpgUS actual achieved last week. The HEV may not be quite as efficient on the highway as the PHEV-11 per the EPA, meaning for most, I "believe" the PHEV-11 allows a larger charge/discharge under charge sustaining mode giving it a bit more glide distance capability. The base HEV is more $10k less $'s although this week we are driving the fully loaded Touring HEV with a sticker of $35,695 including D&H.

    It is also nice to have a dynamic SoC display in the HEV to judge when to fire off the ICE vs. the PHEV-11 that stayed stuck at 2 bars (I saw 1 bar three times for about 30-seconds each when crawling around a parking lot) the entire time.

    I did not mention this in the PHEV-11 thread but pairing a smartphone took about a minute and once complete, complete control over your phone via BT and Pandora use is as simple as selecting it from the steering wheel mode control button. I also received my first text message which the NAVI lady read back and allowed me to reply with a very short reply including "I am driving and will reply later" via selecting #1, #2, #3, #4, or #5 from the available responses. I have been in vehicles that supposedly had that in the past but have never seen or experienced it in real time until last week in the PHEV-13. Pretty slick although still more distracting than no smartphone at all.

    Hi All:

    2014 Honda Accord HEV Review

    Rear seat and trunk load out.

    Initial top off at a Shell in La Mesa, Calif. (600’ elev.) on I-8 just west of San Diego.

    600 to 4,000 ft: in just over 30 miles: 30.3 mpg over 30.3 miles actual with a 53 mph avg. speed.

    3,576 RPM engine braking after pack fill on long descent. Saw as high as 3,800.

    Wind turbines on I-8

    At the In and Out in El Centro, Calif. - 50.4 mpg displayed - 51.2 mpg actual - 54 mph avg. speed.​

    Hi All:

    2014 Honda Accord HEV Review

    I-8 and the AZ Border.

    Immigration Check Point – On the I-8 just north of the US-Mexico border in AZ somewhere.

    Florencia Pizza in Sun City West, AZ.

    Final calibration topoff at a Shell in Sun City West: 47.8 mpg - 345.2 miles displayed -- 48.6 mpgUS actual over 348.0 miles on 7.165 gal.​

    From about 2,500 ft., over the top of the peaks and all the way to the Phoenix area, there was a 10 to 20 mph headwind so the above result was not representative. From a 53 mph avg. speed at the 4,000’ level, I reached a high of 56 mph before turning in to the jam packed In and Out burger in El Centro. As we left, the avg. speed was down to 52 mph. When we turned off on State Route 85 and the I-8, the avg. speed was up to 58 mph. It held until the turn off the I-10 and the 101 heading North. Another 20 miles of surface streets through Glendale, Sun City, Surprise and finally Sun City West for dinner at relatives pizza outlet saw the avg. fall to 53 mph. After dinner, I stopped at a Shell about two blocks away for the final top off and aFCD calibration calculations.

    Hi All:

    2014 Honda Accord HEV Review

    103.9 mpg over 23.7 miles - 105.6 mpg over 23.9 miles actual​

    To begin, I arrived with SoC at 5 bars. I had to drive in a very short 1 block loop multiple times to bring it back down to 4 bars. .8 miles to be exact. I launched with 4 bars and just .1 miles later I was at three. In other words, The hysteresis in the SoC calculation and subsequent display is not very accurate.

    Once on a roll, here are some things that current and future Accord HEV owners can use. Once you know your daily route, if coming up on a slight downhill glide and you are at 3-bars, fire off the ICE and get it up to 4-bars as quickly as possible. It only takes about 3 blocks to bring it up to 4-bard in city scenario. You do not want to be wasting a downhill glide with the ICE running needlessly to bring SoC back up to 4-bars and it will. Trust me on this. It took me 3 loops of the 6 loop drive to figure it out but once dialed in, the FE came up from the mid 90's to over 100 mpg pretty quickly.

    Compared to the PHEV-11 from last week, the HEV is harder to drive but with the far more detailed SoC display, it provides information on when to get that ICE fired back up that the PHEV did not provide.

    I have the steady states data but Marian once me to do some work at a relatives home here in Phoenix that will soon be up for sale. After that we have to drive back to San Diego.

    Winds might be lighter this afternoon then the 10 to 20 mph headwinds experienced while driving to Phoenix so I will start up a MyTracks and see what a measured higher speed run looks like.

    Hi All:

    I stopped at a gas station stop just off the I-10 in Goodyear, AZ to install the Garmin for elevation matching prior to the Steady State testing.


    While there, I saw a Hispanic family w/ an old junk Chrysler minivan and an empty gas can in hand. They had no $s, the father could barely speak English and the kids looked hungry. I gave them some money for gas and food. Someday that father will surely forward that favor to another family in need.
