Series of unfortunate events: Forgot to plug in the car last night (first time in almost a year of ownership!) Headwinds of 16 MPH+ on the way to work Weather finally was nice today ... Needed AC on the drive home Combined with normal factors: I only charge to 79% SOC for battery longevity My round-trip commute is 111 miles So I start my mornings with 245 miles of range (before enhancement)and 256 miles after the update. On paper, that's plenty to make it to work and back twice. But I think we all know that isn't how it works. So I return after driving to work and back (couple small detours for my wife's birthday) and now have 133 miles of range. Next morning, oops! Forgot to plug it in. No worries I will either make it or stop by one of the 3 nearby SCs to my commute. I get to work against a 16 MPH+ headwind with 72 miles remaining. Decide I shouldn't need SC since it's only 55-56 miles home. After work, realize that it's nice weather and hot in the car, so I will need AC.... Still should be fine with 16 theoretical extra miles of range. Made it home with 12 miles to spare. I think I would NOT have tried to make it home without an SC stop without this new range extention. Thanks Tesla! PS-I realize that this scenario was ENTIRELY self inflicted. I purposely selected 79% SOC to be the lowest amount to let me forget to charge and still be ok. I have access to SCs without difficulty . I chose to push this a little to validate the new range, help normalize the battery and learn a little bit about how my Model 3 reacts to being so low.
