On the surface, Tesla’s Model 3 is already highly successful and well-received among those who have driven it.

But the vehicle’s architecture and technology are also believed to represent a significant step change by several people doing breakdowns and reverse engineering the vehicle.

Now we get a great visual look at the powertrain through a new teardown.

After its own Tesla Model 3 teardown, Munro and Associates thought of the vehicle’s electronics as a masterpiece and a German engineering firm was also quite impressed after reverse-engineering the Model 3.

The entire powertrain is extremely compact with Tesla incorporating a lot of the electronics directly into the battery pack enclosure.

We already managed to have a good look at the details of the powertrain architecture with previously leaked information, but we now get to see the impressive architecture thanks to longtime Tesla hacker/tinkerer Ingineerix who has been tearing down a Model 3 and posting a series of videos about the vehicle’s powertrain.

The videos are very short and to-the-point which makes the whole series easy to watch and only about half an hour in total and I highly recommend it for anyone interested in the Model 3 or electric vehicles in general:

Ingineerix says that he weighed the whole drive unit and that it weighs just under 200 lbs. Here we see it without the inverter.
