Tesla Model X Gets Its Numbers From EPA


Originally published on EV Obsession.

The long-awaited Tesla Model X is almost here, and we’ve got another sign that it’s ready to roll. Aside from getting its HOV-lane sticker and EV rebate eligibility from California, the X is also now listed on the US EPA’s website, which shows its official “fuel economy,” range, passenger and cargo space, and other specs. There are just two versions of the Model X listed so far, the P90D X and the 90D X. It’s not clear yet if Tesla will offer Model X SUVs with smaller (or larger) battery packs, but it’s presumed the company will — perhaps just after production ramps up a bit.

I took some screenshots comparing the Tesla Model X P90D and Tesla Model X 90D for your viewing pleasure (you’re welcome) and for easier reference here. Check ’em out:

92 MPGe (37 kWh/100 miles) and 89 MPGe (38 kWh/100 miles) — pretty wicked efficiency for an SUV that seats 7 and is quicker than almost every sports car ever produced, eh? Of course, that was expected, since the X is an electric vehicle, but it’s still very much worth highlighting.

Perhaps of more interest to soon-to-be owners and potential owners is range. As we noted the other day, the rated range of the Model X P90D recently rose to 250 miles (from 240 miles) in the design studio that only Signature X reservation holders invited to configure their cars are able to see. That might have simply changed at the last minute when the EPA rating was finalized. For the Tesla Model X 90D, range is predictably a bit better, sitting at 257 miles. Naturally, the range can vary a great deal based on how you drive the vehicle and external factors such as temperature.

Interestingly, from the “Specs” tab, the EPA says the Model X is not a “gas guzzler.” It also indicates passenger and cargo/luggage volume (separately), electric motor and battery size, and expected charging times. As I explained in my “Electric Car Charging 101” piece, most electric cars have a 6.6 kW onboard charger, and a few have a 3.3 kW onboard charger, while the Model S has a 10 kW onboard charger or, if the buyer pays for the extra option, a 20 kW onboard dual charger. The X seems to have the same. To put that in terms that matter for the average human, here’s the point:

  • a 3.3 kW onboard charger allows an electric car to add ~11 miles of driving range in an hour at 240V;
  • a 6.6 kW onboard charger allows an electric car to add ~22 miles of driving range in an hour at 240V;
  • a 10 kW onboard charger allows an electric car to add ~29 miles of driving range in an hour at 240V;
  • a 20 kW onboard dual charger allows an electric car to add ~58 miles of driving range in an hour at 240V.

Yet another big benefit to Tesla vehicles.

I think that’s all the Tesla Model X news for the time being. We’ll have much more in a few days… if not sooner. If you missed any of these recent pieces, though, check them out now:

    Zac, it rose to 250 miles from 240 miles, not to 150 miles from 140 miles.

    • haha, how the heck did i make those typos!! fixing. 😛

    This information was not found on the EPA website but rather:


    • Joe Viocoe

      That website is still from the EPA.

      • Ticobird

        In the spirit of being factually correct the webpage header lists the U.S. Department Of Energy and the Office of Transportation and Air Quality and the U.S Environmental Protection Agency. At one time (2011?) congress thought about merging the EPA and the DOE but “The Obama administration “unequivocally opposes” a Senate GOP bill to merge the EPA and Energy Department into one super-agency.”

        In my quick web search I could find no information stating the EPA is the author of http://www.fueleconomy.gov/.

        All I was trying to do was provide the parent page for finding this particular vehicular information since it was omitted from the article, i.e., except for the articles image of the information.

        After searching some more I found this document:

        which is interesting and readers may find enlightening concerning how EV’s are evaluated for fuel economy. Finally the last point in the pdf link above states as Joe already corrected me; “3. EPA Confirmatory testing – Currently, EPA performs confirmatory testing on all new light-duty
        electric vehicles and plug-in hybrid vehicles at EPA’s emission testing laboratory in Ann Arbor Michigan.
        If the manufacturer makes changes to an EV or PHEV that was previously tested at EPA, EPA will decide
        on a case-by-case basis whether additional EPA confirmatory testing is needed.”

        • Indeed. Ratings come from the EPA, but website is of the DOE. Correcting.

    “…while the Model S has a 10 kW onboard charger or, if the buyer pays for the extra option, a 20 kW onboard dual charger.”

    This used to be an option, but has not been for some time now. All Teslas ship with two 10kW onboard chargers for 20kW onboard charging capability. It’s all included now just like Supercharging. There’s no reason to believe that it will be an option on the Model X, but will be rolled into the vehicle price just like the Model S.

    As already noted by Johnny Le, you have a couple of typos. The Model X P90D has a 250-mile EPA range, up from 240 reported previously, not the 150 and 140 mile numbers you have in your article.
