A series of internet videos covering Munro’s assessment garnered more than 36 million impressions in little more than a month. Sandy Munro, CEO at Munro & Associates, the benchmarking and competitive analysis firm renowned for its highly analytic “teardowns” of popular and innovative vehicles, recently completed a teardown of a Model Y. It took us a lot of iterations, by the way, to get there.” The single-piece casting has no CNC machining – it doesn’t even have datums.

“The current castings, because you’ve got to interface with so many different things, we have to CNC-machine the interfaces and there’s a bunch of things that have to be joined they have datums on them and that kind of thing. Later this year,” he said on the podcast, “we’ll transition to the rear underbody being a single-piece casting that also integrates the rear crash rails. “The current version of Model Y has basically two big high-pressure diecast aluminum castings that are joined and there’s still a bunch of other bits that are attached. Musk spoke in detail about the new casting process in an episode of the “Third Row Tesla Podcast” in April and made more than a passing mention of it in Tesla’s 1Q2020 financial results call in early May. “Elon Musk has always pressed his engineers to be creative.”

“It’s definitely an all-new look at how to do things,” asserted Laurie Harbour, president at Harbour Results Inc. Musk is renowned for outsized promises, but in the case of the Model Y’s die-cast rear underbody, his enthusiasm for this advanced use of aluminum – cast by a house-sized “giga press” – is supported by manufacturing experts who call it a game-changer. According to Tesla CEO Elon Musk, this new aluminum application represents a radical step for its design and manufacturing advantages and its lightweighting potential. But apart from a few applications – most notably Ford’s F-Series pickups – aluminum largely is deployed where steel can be readily displaced without performance loss or for comparatively small components that deliver comparatively small weight or process savings.Įlectric-vehicle maker Tesla is readying the next step in aluminum use, however – one that effectively matches Ford’s “big gain” approach by specifying a massive piece of structural die-cast aluminum for the rear underbody of the recently launched Model Y crossover.
