This is a good topic to ponder! In the slide deck Tesla listed current factory capacities:
Fremont: 650K
Shanghai: 950K
Berlin: 375K
Austin: 375K
TOTAL: 2,350,000
Now, regarding Austin, 125K of that capacity is the 125K CT production, which Elon himself said will take about 18 months to ramp up to. So for 2024 we can expect the CT line to NOT hit that 125K number, we are more likely to only see about 60K CT's in 2024.
This means for next year, 2024, we are looking at a probable production number of 2,285,000. This would only be about 27% above 2023 expected production of 1.8 million.
Now for 2025, we really don't have any new capacity coming online that we know of. Mexico's buildout is delayed and Berlin seems stalled in it's ramp, so for 2025 we're likely only going to see a bit more production than 2024 due to the CT ramp being mature. We might see some more line improvements to existing factories which might equal slightly higher run rates, but nothing extraordinary. Maybe Berlin will gain some production as well?
I'm expecting 2025 production to be barely above 2024 production. Maybe 2,500,000 or so? 10% above 2024 production numbers. I just don't see many possible paths to gain lots of production in that timeframe given the current production capacities and buildouts.
So yeah, I'm expecting the growth rate to slow for a year or two, until Gen3 production comes online in either late 2025 or 2026, and especially until Giga Mexico is built and producing.
