Ford C-Max Energi Gets Official EPA EV Range of 21 Miles, Total Range of 620 Miles

5 years ago by Lyle Dennis 43


Ford announced today that its soon to be released plugin hybrid C-Max Energi has received an official EPA rating for all electric range of 21 miles and total driving range of 620 miles.

Ford points out that the vehicle’s electric range is thus more than triple the plugin Prius electric range of 6 miles.

Furthermore the Ford can travel all electrically up to speeds of 85 mph compared to the Toyota’s top EV range of 65 mph.

The 21 miles of all electric driving will be provided by the on-board 7.6 kwh lithium ion battery pack. Drivers can choose to drive EV at the onset of their drive (EV: NOW) or save it until later (EV: LATER). There is also an EV: AUTO mode in which the powertrain computer automatically selects the appropriate blend of battery usage and engine usage based on demand and the state of battery charge.

Once the EV range is depleted, the C-Max Energi will achieve 43 MPG combined city/highway running in hybrid mode.

Ford points out that the average commuter drives 20 miles one way to work, allowing them to drive all that distance on electricity. If they can recharge while at work, the average commuter could avoid gas altogether.

The C-Max seats five in a crossover hybrid-specific design, and will retail for $29,995 after a $3750 federal plugin tax credit.

The Ford’s total range of 620 miles on one tank of gas and full battery beats the Prius plugin’s total range of 540 miles and the Chevrolet Volt’s total range of 380 miles.

Ford previously reported the C-Max Energi has a combined EPA rating of 100 MPGe, better than Prius and Volt, and generates 188 hp better than the Prius’ 134 hp and the Volts 149 hp.

“C-MAX Energi is a great symbol of how Ford has transformed itself into a fuel efficiency leader across our lineup, giving customers the power to choose a fuel efficient models that fit their needs as some of our customers face record gas prices,” says John Davis, C-MAX chief engineer. “With gas prices spiraling upwards of $5 a gallon in some parts of the country, every mile to the gallon makes a difference. C-MAX Energi’s best-in-class fuel efficiency and range is more important to our customers than ever.”

    “Furthermore the Ford can travel all electrically up to speeds of 85 mph compared to the Toyota’s top EV range of 65 mph.”

    Does this require the driver to press the EV only button?

    1. usbseawolf2000 says:

      The default startup mode is EV for Prius PHV and the driver can hit the HV/EV toggle to switch. I would assume “EV Now” would be the default for C-MAX Energi and the driver can hit “EV Later” to override.

      1. Brian says:

        Actually, the C-Max has a third mode – EV Auto. I suspect this will be the default. I just hope that I don’t have to hit EV Now every time I start the car…

        1. evnow says:

          Absolutely – I don’t want anyone to be hitting me when they start the car 😉

          1. Brian says:

            That would be especially awkward since I’ve never met you! 😉

          2. ClarksonCote says:

            Hilarious! LOL

  2. Schmeltz says:

    21 miles AER and 620 miles total range are good numbers. I think the price is very comptetitive too for the segment. I hope that Ford sees sales success with this and the Fusion Energi, and it inspires them too make an Escape Energi model. Has InsideEVs heard anything about a potential Escape plug-in?

    1. usbseawolf2000 says:

      A midsize typically cost $3k more than a compact. I think the pricing is really good too.

      Escape hybrid was discontinued and C-Max hybrid is supposed to replace it so I doubt there will be Escape Energi.

  3. Mark H says:

    I wanna see this one on the monthly Cole report!

  4. Erik says:

    Can you guys dig deeper into why the hybrid mode disconnect between energi and hybrid versions of the C-max? Is the 43 real and the 47 overstated or is there a physical difference (weight, gearing etc)

    1. Brian says:

      I second this request. I would love to get a better understanding of the 43-vs-47 difference

    2. usbseawolf2000 says:

      We know weight is different. Perhaps gearing is different as well because Energi top speed is 102 mph while hybrid is 115 mph. My guess is, the PSD gearing is different to accommodate 85 mph EV top speed.

      1. Brian says:

        Again, this is your guess. I would like to have a more affirmative (and researched) answer as to the differences between Hybrid and Energi

    3. Charles says:

      The 43 and 47 are both guesses at this point, but the math favors the 47. Here is the evidence:

      (620 – 21) / (0.9 * 14) = 47.5

      That is 620 mile total range, minus 21 mile all electric range divided by the EPA standard of using 90% of the tank size for range and a 14 gallon tank. 43 MPG would be for the whole tank, which is not what the EPA uses. The 90% figure can be verified by going to http://www.fueleconomy.gov and looking up the C-Max Hybrid with its 13.5 gallon tank, 47 MPG and 571 mile range.

      I do think there is a weasel wording about up to 21 mile EV range. I think that would be a 21 mile city EV range. I suspect that the overall EV range is going to be 19.

  5. scottf200 says:

    “Toyota’s top EV range of 65 mph.” — I think this should be 62 mph (eg.100 kph). 85 is impressive for the Ford C-Max. That makes the car more real-world on various highways.

    1. usbseawolf2000 says:

      Best of all, it doesn’t discriminate fuel types. Gasoline engine will be used (combined with battery/e-motor) for hard accelerations and very high speeds — teamwork is still at play.

  6. Nelson says:

    Ford states the C-Max Energi has a 14 gal. gas tank.
    At $4/gal., infrequent fill-up will be > $50.
    IMO, they should have gone with a 10 gal. tank and a slightly larger battery.

    NPNS!

    1. Test2488 says:

      I’m glad to hear that the C-Max Energi has a 14-gallon gas tank. The bigger, the better. I’d also like to see as high capacity battery as possible. Ideally the system would be modular so that batteries could be added as appropriate, and for all that energy to power accessory outlets and such.

      In the Tesla Model S, the 85 kWh battery power cannot be used to power 12V devices and inverters, as I understand. A separate very small 12V battery is used for this purpose. How about in the C-Max Energi, I wonder if a DC-to-DC converter is used to power 12V DC and 120V AC devices using all the energy in the big battery. Hope so, this would be very cool.

  7. usbseawolf2000 says:

    21 miles at 100 MPGe would use about 7.1 kWh out of the 7.6 kWh battery. That’s a really deep cycle.

    1. Anthony says:

      Especially if we see a proliferation of EV stations where people can charge at work, or at the mall, etc.

    2. Charles says:

      Ford used weasel wording on the EV range. I think the “up to” indicates that they are using the 108 MPGe of the city cycle. It is still an 85% cycle, but that is better than the 93% that the combined cycle would use.

    3. usbseawolf2000 says:

      That makes sense. It would use about 6.6 kWh out of the 7.6kWh battery if 21 miles is city at 108 MPGe.

      Using EPA 55% city and 45% highway, it should be 90 MPGe on the highway (to get 100 MPGe combined).

      At 90 MPGe highway, EV range would be 17 or 18 miles. The combined would be 19 or 20 miles.

  8. usbseawolf2000 says:

    “Ford previously reported the C-Max Energi has a combined EPA rating of 100 MPGe, better than Prius…”

    Prius PHV’s electricity consumption is 29kWh/100mi. That’s 117 MPGe. Gas consumption is 0.2gal/100mi (50 MPG). The combination of both is rated 95 MPGe with 11 miles range. Beyond that is 50 MPG.

    C-Max Energi is rated 100 MPGe because it completed the entire EPA cycle without using the gas engine. 100 MPGe is good for 21 miles and then 43 MPG with the gas engine in hybrid mode.

    If your commute is short and below 62 mph (due to congested peak hours), Prius PHV is a good choice, especially with $3,500 cash bonus currently going on.

    If you need to drive at highway speed and have about 20 miles commute, C-Max Energi is a better choice. Both provide midsize interior and runs on regular 87 Octane gas.

    1. DrInnovaiton says:

      Its not appropriate to compute MPGe for a mixed mode operation without computing mixed-mode MPGe using both sources. Stating the prius PHVs MPGe from electricity on its 11 mile CD range is wrong and the sign of a desperate attempt to spin the PHV as competitive.

      I’m gald to see, though slightly surprised, at the 21 miles AER of EPA rating. The C-Max provides a good alternative for those that need seating for 5 and more cargo than a Volt.

      It may be two years late to the party, but at least is bringing something worthwhile to the mix.

      Overall the volt will likely provide lower gas usage and overall MPGe when the weighting of CS and CD modes are included (will depend on the 4 way mix of highway vs city and CS vs CD and I’ve never seen the mix used to decide the Volt was, overall, 60 MPGe).

      The CMAX gets better EV range than the PHV, can stay in EV for almost any drive, and costs less than the PHV. Its hard to consider any “requirements” for which the PHV is now the most competitive PHEV — its market will soon be just the Toyota loyalists and those who want HOV access without actually bothering to plug in. Glad to see American manufactures stepping up and making solid hits and home runs.

      1. usbseawolf2000 says:

        I apologize if I wasn’t clear. 117 MPGe is for 6 all electric miles. 95 MPGe is for 11 blended miles (EV Boost).

    2. Gwido says:

      “Gas consumption is 0.2gal/100mi (50 MPG)”

      0.2gal/100mi is 500 MPG. I guess it uses the ICE (at 50 MPG) about 10% of the test run.

  9. Erik says:

    do we have details on C-Max Energi heating/cooling operation? Preheat and/or Precool on the mains?

  10. MrEnergyCzar says:

    Is the battery liquid cooled? They are using a high percentage of the battery….

    MrEnergyCzar

    1. Koz says:

      No, the battery is air cooled. While it is capable of 85mph on electric only I wouldn’t advise it regular use. 85mph requires a high C rate and with air cooling that is a bad combination.

  11. Koz says:

    What are the highway and city breakouts for mpg’s in hybrid mode?

    1. Charles says:

      Nobody knows at this point, but a good guess on combined hybrid MPG is 47. See my post above for the math.

      1. Koz says:

        Fords states 43mpg combined which is given in Lyle’s article.

  12. America1st says:

    I’m a Volt owner. I enjoy the EV ride of around 40 in the Volt. Love to see every American car that achieves this kind of mileage helping free us all of the stranglehold of a $450 billion dollar annual energy deficit. Bring em on ALL of them.

  13. NeutronFlux says:

    Good to see Lyle still typing away on EV’s been awhile since I was at his stomping grounds (GM-Volt.com). Good to see other EV’s, sad to see they have not learned from Leaf experience in Az. heat kills capacity quickly. Those in hot environments should do their homework before buying air cooled. As a So. Cal. Leaf owner I strive for 80% charge to increase longevity. My range on a full charge at 55 MPH is about 77 miles. Still hoping some of that new battery tech makes it to market / production. Nothing sweeter than the electric hum of battery power as you pass the gas station at $4.65/gallon.

  14. JP says:

    When will the Energi arive at dealerships? Fall 2012? I thought that October was in the Fall.

    1. Brian says:

      October is in the fall, but so is November and most of December. Remember the Focus electric was to be delivered starting in 2011? Yeah, they delivered one by Dec 31, 2011.

      1. Jay Cole says:

        FWIW, we should have one eminently.

        1. Gwido says:

          imminently?

          1. Jay Cole says:

            I don’t have to do any of them spellings and grammars when Im not doing the writings.

  15. Raymondjram says:

    How big is the C-Max? Is it as big as the 2013 Escape?

    1. Jay Cole says:

      Same basic exterior dimensions, Escape has a couple inches more on the wheel base, and 4″ in overall length.

      Inside you are about the same in the front, maybe a little more, back seats are the same, slightly narrower, but cargo volumes are way off, especially in the Energi behind the second row, battery pack is chewing up big time space.

  16. Tom says:

    Prius Plug in range is 11 miles by EPA not 6 miles as stated in this post.

    1. Jay Cole says:

      It is Ford that is quoting the number, and actually, in the case of the Prius Plug-In, the EPA quotes two ranges, one for electric plus gas, which is 11 miles, and one for “All Electric range” which is 6. But it appears from a glance at the sticker it is 11 miles.

      If you will note on the EPA sticker the 11 miles is noted as “Gasoline +Electricity” and the fine print underneath quotes the “All Electric Range = 6 miles”

      null

      Not that it can’t go 11 miles, but it can’t comply with the EPA highway testing scenarios, so as soon as the gas engine flips on (at 62 mph or various driving loads) the all electric portion of the test is nulified.
