Last week, Tesla hit a new record of producing 4,000 Model Y vehicles in one week at its Giga Texas facility.

The EV manufacturer continues to ramp up production after recently hitting 3,000 Model Ys in a week in December at its Giga Texas factory, according to Teslarati.

Tesla’s factory in Germany, Giga Berlin, also hit the 3,000 Model Y per week milestone in December, quickly hit 4,000 vehicles per week in February, and then scaled up to 5,000 per week in March, per Teslarati.

Giga Texas aims to match Giga Berlin’s output at 5,000 Model Ys per week, as both factories are locked in a friendly competition to increase production of Tesla’s fastest-selling vehicle.

Giga Berlin opened just 11 months ago and is now on track to produce 250,000 Model Ys per year, which is nearly enough to supply demand in the U.S.

The Model Y was the sixth best-selling vehicle in America in 2022 and the best-selling EV, with 252,000 units delivered, according to InsideEVs.

Tesla produced 1.38 million vehicles overall in 2022, the outlet reported.

Part of the reason why Giga Texas is now trailing Giga Berlin is due to Tesla’s 4680 battery cells that are used in some vehicles made in America. Tesla has struggled to ramp up production due to these batteries, according to Electrek.

Tesla has shifted to producing some Model Ys with more expensive, “superior energy density” 2170 battery cells, which are used in other Tesla factories, Electrek reported.

The EV leader has also been focused on increasing its Cybertruck production at Giga Texas, which is expected to be released later in 2023, according to Benzinga.

Tesla is on a hiring spree for the Cybertruck roles, with its career page listing over 60 Cybertruck-related positions, almost all of which are in manufacturing.

On Sunday, Tesla CEO Elon Musk tweeted that he spent several hours walking the entire Cybertruck production line at Giga Texas, saying the car is “gonna be awesome!”
