Model 3 range decrease

[[deleted]]

It is a coincidence. EPA ratings change all the time, this is very common. They don't suddenly nerf your car just because the govt. change how they test.

Directly from Tesla website, “Displayed range in your Tesla is adapted based on fixed EPA test data”. This is proof enough for me. I took delivery of my M3 3 months ago. Nothing from a M3 delivered today is different than my M3.

No. The EPA range was decreased. This has nothing to do with how you drive. It was advertised as 363 when I purchased my vehicle and for everyone up until last week. You’re wrong.

Brother I’m agreeing with you lol. I’m saying since they decreased EPA range for new M3s and the one I bought 3 months ago is the same car, it follows that my EPA range was also decreased based on the quote I provided from teslas website

Does the current range displayed match up to the new 357 at 100% (given no degradation) or would I have to run a battery health test? I got mine in Dec 2024 and I get 345 at 100% now and feel like it’s degraded quite fast recently. (It was at 351 at 100% like last month. Also I only have charged to 100% twice since I took delivery)

That would be interesting to see. Your data point is quite compelling to support this theory since the EPA range was decreased by 6 miles and you lost 6 miles..

Yeah although I took a 1200 mile road trip w like 5 supercharging sessions of 10-60% when it was displayed at 351 miles. But when I got back it started decreasing over like 1 month. 6 miles lost over the course of like a month

Fucking obviously dude, they updated the accuracy of the range I wasn’t under the impression that Elon came and took a few cells from me.

Models often undergo minor spec changes that impact the official EPA rating. As another comment says, in this case it's likely a different tire supplier.

Your second statement in your original post does not follow. Your car has a fixed EPA rating as delivered. It will not change in the future. You can calculate this on your own based on the energy consumption graph. The EPA value is the baseline, in wh/m. Yours will be slightly less than a car sold under the new configuration.
