Tesla is struggling to ramp up production of the Model 3 sedan, but that’s not stopping the automaker from thinking about its next vehicle, the . And if a is accurate, Tesla wants to start production on that vehicle by 2019. In the same California factory as the Model 3. Which is supposed to be at capacity by then. Aaaaalrighty then.

Citing two unnamed sources with knowledge of Tesla’s supply chain, Reuters reports the automaker is targeting November 2019 as the launch for production of the Model Y, with production in China beginning two years later. Tesla is accepting preliminary bids from supply contractors, Reuters says, and though it hasn’t provided a production timeframe, it reportedly plans to start building the vehicle at its current factory in Fremont, California.

Here’s more from :

Tesla issued to suppliers what is known as a “request for information,” or RFI, which gives a directional view of what will be needed.

With a new car model, automakers normally choose parts suppliers two to two-and-a-half years before the start of production. At about one-and-a-half years away, a November 2019 start date for the Model Y would be considered “aggressive, but possible,” said one of the sources. A shorter timeline is potentially feasible, the source said, as the Model Y will be built on the same platform as the Model 3.

Aggressive is an understatement. last fall that Tesla raced ahead with a similarly aggressive production timeline for the all-electric Model 3 sedan, and the automaker’s been dealing with manufacturing bottlenecks almost from the outset.

Tesla thinks it can ramp production up to 5,000 Model 3s per week by the summertime, the company said earlier this month. The repeated delays have inhibited Tesla from generating its anticipated revenue stream from the Model 3 and put it in a position where it may have to raise additional capital from investors by the end of the year, though the company advised it doesn’t expect to need additional funds.

Tesla CEO Elon Musk said in February that it’s hoping to eventually produce one million Model Ys annually. The automaker’s Fremont plant is said to be able to per year, though Musk has suggested he thinks Tesla .

Musk has a tendency to exaggerate, which is why this passage in the Reuters story stopped me in my tracks.

The two sources said suppliers could be estimating an annual production of 500,000 vehicles in the United States, with much lower volume in China, likely in the tens of thousands. Building 500,000 Model Ys per year would be the equivalent of what Musk has planned for total production in Fremont by the end of this year, although the company is nowhere near that volume.

And so, as we’ve said before, where’s it going to be built? Putting the Model Y on the same platform at the 3, sure, you could pump out a few Model Ys per day. But Tesla also plans to start production of a new semi in 2019. And a new Roadster in 2020, also, in ... Fremont, I guess? The Gigafactory, maybe? Where is all of this production happening? I’m pleading, anyone with info, please tell me.

Tesla didn’t immediately respond to a request for comment on Reuters’ report.
