Model 3 Performance Average Consumption Improvements?

[louco73]

I have a M3P from December 2019 that averaged around 178 Wh/km for the first 3 years or so, but since our Xmas trip to VIC it's come down to 168 Wh/km. The trip to work in Brisbane and back yesterday confirmed the same 168 Wh/km consumption too. I'm wondering if people with M3Ps of a similar age have seen this improvement and what is the average consumption of the newer M3Ps?

I’m getting lifetime 174/km for a 2019. Long trips is good weather are better - best down to 143. Long trips in terrible weather up to 235

Are you sure tyre circumference doesn't explain the % differences?

Do you mean from wear, @Nobody Famous? I haven't changed from the normal tyres on the M3P and despite losing 3 tyres to pot holes and rough roads the tyres have been the same for some time. I doubt a few mm of wear would make that much difference.

The main thing that has affected my energy consumption is less strenuous acceleration. Makes by far the most difference around town. I can’t say I’ve seen much change in consumption with software updates

Either wear or spec change that changes rolling circumference, and therefore estimated distance travelled. Maybe tyre pressures could do the same? You are only talking ~5% difference in consumption

I've got a 2021 (so bit different and with the heatpump), but my longterm average is 160 wh/km. That's with plenty of spirited driving, highway cruising and stop and go traffic. Haven't noticed any difference caused by software updates. Biggest difference for me is actually temperature related. Efficiency really does decrease when the temperature drops below 10c.

My completely unscientific impression over several winters now has been that it's mostly the increased climate control use. Not really willing to drive around in an icebox just to know for sure, though!
