Testing with the structural battery pack with 4680 cells in the updated updated MY layout has been going on for the past several months using pre-production MYs. At the Q3 2021 earning call, in October 2021, the following was said (directly copied from a transcript of the earnings call):

Martin Viecha
Thank you very much. And we will now take questions from institutional and retail shareholders that we posted on our website. The first question is, when should we expect the first vehicles to be delivered with 4680 cells?
Drew Baglino -- Senior Vice President
Yeah. Thanks, Martin. Early next year, from a non-cell perspective, structural, battery, crash, range, and reliability testing are on track to be complete this quarter. Testing is -- to date has gone well, and the Fremont manufacturing line is on track to support.
However, similar to what Zach said before, this is a new architecture and unknown unknowns may exist still. Our top priority is ensuring quality in what we deliver. And from a cell perspective, we are comfortable with the design maturity and manufacturing readiness, matching the pack timeline I just mentioned.
