Ultra boring stuff, but a sign of progress nonetheless!

The drive unit castings will need to go to Toledo Propulsion... and then the finished drive units will make their way to Detroit (Hamtramck or Factory Zero). Yay! I wonder where the GMC Hummer EV drive units are assembled today... some garage somewhere in Livonia maybe?

Tesla stans will be scoffing at GM using aluminum die castings instead of a Gigapress to form the drive units. Tis one of the sad things about GM having a legacy supply chain and old school mindset.

mmm....Tesla's gigapress MAKES aluminum die-castings...they are just BIG die castings for large structural body parts. Large volume aluminum drive unit castings are produced using a similar high-pressure-shot technique, but just a lot smaller tonnage pressure required for the smaller parts. Foundries use the right press for the right part. Bedford likely has exactly the right press for high-volume drive unit die castings.

Tesla stans still have to worry about whether or not parts are going to fit properly and fall off once they drive their cars home, I'll put my chips on how GM has been doing things.
