MotorTrend is running an overview of the 6000-person-hour teardown of a Tesla Model 3 by Munro & Associates, a well known reverse engineering and manufacturing consulting firm. A couple of details from the text (there are many photos as well):

Front Upper Control Arm—These are formed of thinner-gauge stamped steel then reinforced by having plastic webbing molded inside. This plastic also provides attachment points for routing the ABS sensor wiring. The oddity: Note the ingot of iron that is glued in place (held by zip-ties while glue sets). Munro reckons this is to dampen a troublesome natural frequency.

Charging Board—This large, complex board filters electricity coming in from the charger with the tall and modular board at right. This board is tailored to suit the electrical service of the vehicle's destination country. This U.S.-market car is prepped for three-phase current, so there are three big copper donuts under that board that look like the one on the left side of the board (that one handles the conversion to 12 volts). This approach is unique and deemed quite savvy relative to the Chevy Bolt and BMW i3 Munro has also analyzed.

Overall, they liked the electronics and panned much of the mechanical design and fastening/welding details--relative to current practice at other auto manufacturers. Which kind of makes sense given Tesla's location near Silicon Valley, and far from Detroit (although Tesla has hired many experienced engineers from existing car companies & suppliers).

The article includes a link to an overview of this analysis, which was published last week.

    Yeah, I didn't mean break even w.r.t. initial investments/loans, I mean just to turn a nett profit at all. And he's ramping up production at a 10th of the rate that he predicted, so that means in reality he'll not be turning a profit for perhaps 2 decades. Would you invest in that? The car industry does have cases that are similar, old independent Aston Martin being a classic example. There are pundits that are valuing TSLA at $0, in case you don't read the business section.

    And also many gamblers shorting TSLA stock (saw a reference in passing, can't find it now).
