Munro & Associates’ YouTube teardown videos are fascinating and informative for engineers, who have contributed to the millions of views these videos attract. But the videos are brief and one-way; we can’t ask questions.
One of the most technically interesting vehicles to enter Munro’s shop last year was the Tesla Cybertruck, and that vehicle’s teardown provided a trove of valuable information. But what was the significance of what the Munro team found inside?
At DesignCon 2025, attendees will have the opportunity to drill down into more detail on the Cybertruck teardown and to ask questions about what the Munro team learned about Tesla’s most advanced model.
Speaker Tom Prucha, who is the Director of Electrification at Munro & Associates, is hosting three sessions that look at Cybertruck’s technology, focusing on a few key elements that he says he thinks are its most significant aspects.
The sessions are:

These sessions look at the truck’s use of 48-volt systems for its low-voltage architecture. This is a long-anticipated industry shift, and Prucha says that he will delve into the reasons for its prolonged delivery from the original plan for it to be a 42-volt system. “This presentation will look at the voltages of various automotive subsystems, past and present, highlight why 48V is needed and it will describe some of the impediments there are to 48V succeeding this time around,” said Prucha.
The Cybertruck’s three-motor drive system also merits examination, so Munro & Associates laid it bare for all of us to see. Prucha promises to showcase the interesting findings from the company’s teardown of the 3-motor Foundation Series Cyberbeast version of the truck, so don’t miss it.
The Cybertruck’s structural battery pack also gets a look, with Prucha planning to talk about how this vehicle’s pack differs from those of earlier Tesla models. That means not only the pack’s structural contribution to the Cybertruck’s chassis but also its use of larger 4680 cells and how the company has installed them upside-down inside the pack and potted them in epoxy. This, and a positive ventilation system for the pack contribute to the Cybertruck’s ability to ford deep water without soaking the cells but will complicate the ability to repair or recycle the pack later in the vehicle’s life.
For details and to ask your own questions relating to these topics, don’t miss Prucha’s sessions. He is the Director of Electrification for Munro & Associates and has been a practicing electronics engineer for more than 40 years, with most of his electronics experience in automotive engineering.
