A few days ago, Tesla updated the Cybertruck configurator page by pushing back the production start date from the end of 2021 to sometime in 2022.
As it turns out, this delay may be have been caused by the fact that company engineers and designers have only recently finalized the electric truck's styling and dimensions. That's according to Tesla insider Sawyer Merritt who cited an unnamed company source.
This won't be much of a surprise but I've been told designs were just recently finalized for Cybertruck. Tesla said on the Q2 earnings call that "Cybertruck is at a stage where we finished basic engineering of the architecture; We're moving into the beta phases later this year."— Sawyer Merritt ????????
