Tesla Model 3 Deep Blue Metallic

Apparently, Tesla is under-reporting its range despite EPA calculations, however, this wouldn't be the first time.

Since the Tesla Model 3 was officially put into production and revealed, the automaker has stood behind a 220-mile range for the base model and 310 miles for the Long Range variant (which is the model the company is currently manufacturing). The automaker has yet to officially release battery information/size or efficiency.

Not long ago, we reported about an EPA certification summary document that surfaced, which seemed difficult for most to decipher at first. However, a closer look at it revealed likely battery sizes (55 kWh and ~80 kWh), as well 126 MPGe. Now, Teslarati has dug deeper into the document and it looks as though the Long Range Tesla Model 3 gets an EPA-estimated combined 334 miles of range. A previous look at Tesla's official window sticker for the car says 310 miles and that is not likely to change.

So, what's the deal here?

In the past, the EPA rated the Model S 100D at 341 miles but Tesla under-reported at 335 miles. Keep in mind that the EPA allows for this sort of adjustment by the automaker. With the Model 3, it's a bit more drastic, however.

Teslarati explains how the EPA goes about coming up with a final figure. The agency goes through a 5-cycle process and once the range is determined, it's multiplied by 0.7 as part of the EPA's weighted system, which accounts for real-world situations. In a combined rating, 55 percent accounts for city range and 45 percent for highway. The full document can be found here.

The test for the Model 3 comes out to 495.04 actual city miles and 454.62 for the highway. Using the 0.7 factor gets us to ~347 and ~318, respectively, hence a combined rating of ~334 miles!

Is this because the Long-Range Model 3 would basically tie with the Model S 100D? Does Tesla really want to keep more people from reserving a Model 3? Is the automaker just making a habit of playing it safe so as to not mislead people? Who knows.

What does this mean for the base Model 3?

Discussions in some forums are tagging the base Model 3 at 239 miles, which would be right around Chevrolet Bolt territory. We've been unable to verify that information.

What do you think?
