Tesla Model 3 EPA Fuel Economy label shows its efficiency

Tesla Model 3 frunk with EPA Fuel Economy label

We now have a first glimpse of the Tesla Model 3’s EPA Fuel Economy label and it confirms that this is a very efficient electric car.

While we already saw Tesla internal efficiency figures for the Model 3, it’s the EPA efficiency rate that matters for a better comparison with other electric cars.

A member of the TMC forum whose username is stopcrazypp noticed the Tesla Model 3’s EPA Fuel Economy label in a picture posted online of its frunk (front trunk). The picture has poor resolution and most information can’t be read, however we can see that the combined efficiency rate is 126 MPGe.

The 126 MPGe figure is impressive, especially considering that it’s for the less efficient longer range version with the heavier battery. This makes the Tesla Model 3 only second to the Hyundai IONIQ Electric which gets an amazing 136 MPGe.

Furthermore, the future AWD (all-wheel drive) version associated with the smaller battery capacity version should be even more efficient.

Since it’s always useful to convert MPGe to kWh per 100 km, with 126 MPGe we get 16,62 kWh/100 km.


The Tesla Model 3 is really the first of its kind, a top performance car that is also extremely efficient. This is something impossible to achieve by Tesla Model 3’s ICE competitors such as the BMW 3 series, Audi A4 and others alike.

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

Unfortunately people buy a bmw 3, Mercedes c class or an Audi a4 give no crap to fuel efficiency.

As an older Audi S4 owner, and supercharged Mercedes owner, I disagree. The problem has always been that there has been a 3-way choice between fuel efficiency, car size, and high performance. For ICE cars, the answer has always been pick 1 or 2 out of 3. It isn’t that fuel efficiency is of no concern, it is that it doesn’t always win in every compromise decision.

The Model 3 is really the first car where you don’t have to compromise like you have to with a BMW or Mercedes or Audi. Especially with AWD and performance packages coming in a while.

That means us BMW/Merc/Audi owners will probably show up in droves, because we no longer have to live with compromises we otherwise weren’t willing to live with.

I just realized that there is an entire story about this linked to in this article. Sorry, first post on this site, I didn’t know. Oh well. Just count me as a third-party confirmation of the accuracy of the previous article. *laugh*

The number is confusing. It implies 83 kwh battery at 499 km range. I was under the impression that it was supposed to be 75 kwh battery max?

Thanks. That explains a lot.

90% would be really low in charging efficiency.

I believe TM3’s battery capacity is 54 kWh (4x Powerwall 2) and 81 kWh (6x Powerwall 2).
Powerwall 2 battery is 13.5 kWh (this is Tesla official data).

Then 83kWh would result in a battery charge of 81 kWh.
