80,000 mile (128,750 km) update for my Sep 2021 SR+ LFP. The car is now 2 years 8 months old and was originally rated at 253 miles on a full charge. The Tessie app shows a battery capacity of 50.9 kWh (down 6.4% from my original Oct 2021 post of 54.6 kWh), and a max range of 236 miles (down 6.7% from my original range of 253 miles, which hasn't changed since my 75,000 mile update). I've had Tessie since my first day or two or ownership, so this data shows the entire life of the car.

According to the car's screen, I'm averaging 211 Wh/mi over the life of the car (no change since the 75,000 mile update). In cold winter weather I can expect 240+ Wh/mi when it's below 30f, and in ideal temps (75-85f) I routinely manage under 200 Wh/mi on my 100 mile round-trip commute. Assuming I could tap into the current 50.9 kWh battery at my lifetime average 211 Wh/mi efficiency, that gives me a real-world range of 241.2 miles.

Today Tesla fired the entire 500-person team in charge of the Supercharger network, and TBH that has me a little bummed. I'm going on a 2,000 mile road trip in the next month, made possible by Tesla's excellent charging network. I'm getting the feeling that Tesla doesn't want to be a car company anymore, so as positive as my experience has been with my Model 3, I'll try to drive it into the ground and then look elsewhere for my next car.
