I saw this video in my YouTube recommended videos and it is fascinating.
It wasn’t so much the Tesla that I found interesting but what it revealed about Tesla and Tesla’s engineers that I found fascinating.
I am a meat space engineer.
My undergrad degree is in Chemical Engineering from way back in 2006. My graduate degrees are in Materials and Metallurgical Engineering.
I don’t know jack about programming. My Excel-Fu is strong but that’s about it. I do not know how to run AutoCAD, Solid Works, or any other modeling software.
My work is in real world physical testing, often destructive testing. I do a lot of manufactureability assessments. What materials to use, how to heat treat them, what order of operations to put them together with, in order to get the most cost efficient process.
Tesla is a Silicon Valley company, based in Palo Alto, California. What is strange is that they are a Silicon Valley company that does meat space engineering.
Using the Halback effect to develop a very efficient electric motor is brilliant. Their battery is a thing of beauty. It is pretty much a 1,200 lbs cell phone battery.
You can tell that the electrical engineering that went into the Tesla is borrowed straight from the laptop and tablet manufacturers up and down the road from them in Silicon Valley.
Their monocoque is an awful pile of overly complex, barely assemblable, excessively expensive garbage.
Absolutley no design for manufacturablty went into the body of the car.
Sandy Munroe, the engineer who did the analysis of the Tesla in the video wondered why this was not caught.
Here is why I think it is. I have experienced friction in my life with the Silicon Valley mindset. It is “we are cutting edge and everything that isn’t cutting edge is a dinosaur.”
Lithium ion batteries, digital electric motors, those are cutting edge. Car monocoque, chassis, and suspension design is old meat space technology. The drive in that is production efficiency. Every once in a while new technology comes along, adaptive damping or something, but a lot of that is actually borrowed from aerospace or racing, where light weight performance is critical. Then the progress of technology and economy of scale eventually make that cost effective for the consumer car.
I have the feeling that Tesla, the young startup, has very few (if any) experienced car designers who built a career cutting weight and cost out of car building for Toyota or Ford, where the profit margins are razor thin.
If they do, I can all but guarantee that those few engineers are treated like ignorant dinosaurs by the hip Cal Tech designers working on the solid state computer system under the hood.
The frame stinks of the “let’s launch the platform and keep issuing patches and updates” attitude of software design.
Every time they needed to make a change, they patched it here, altered it there, and never had any consistency in assembly.
I have more evidence to back up my theory. This video on this guy who fixes his own Tesla.
This is the Apple warranty. Once your iPhone is off warranty, you buy a new one. Don’t crack it open, you will not get replacement parts, you can’t update anything.
That works for a $900 phone. Not for an $80,000 car.
And look at the shoddy, shitty assembly. That’s a lot of miles but not a lot of time, so headlights, taillights, and trim shouldn’t be leaking like that.
This car was built to be the iPhone of cars. It’s great and loved by the people who own is just long enough for the next model to come out two years later and upgrade it. If you are not that fanboi customer, fuck you.
The Tesla really is a physical manifestation of the differences in thinking between Silicon Valley engineering and classical real world, meat space, engineering.
Thanks for the great analysis! Now the price tag makes sense!
[…] I was reading J. Kb.’s post where he mentions “Apple Warranty” and I was reminded a series of videos I bumped by accident in YouTube about an non-aligned Apple repair guy.My animus boycott for Apple was renewed for another 40 years after seeing them. […]
I come from the aerospace engineering world. I think you’re exactly right on the difference between Tesla engineering and the guys who come from the big car manufacturers.
But it’s not just them. Think of the guys coming from the “take a buck each out of the price on a million cars” mindset and going into the $80,000 electric car market.
There was a story about a Ford (Fusion?) electric car being taken out by a lightning surge as it was charging. It was connected into the house’s wiring and the house got hit. Massive expensive damage to the car, and the owner lost the car for months. That’s preventable with attention to engineering detail.
In the consumer electronics world, things that cost under a $k-buck, surge protection costs a couple of bucks and they leave it to the customer. In the aerospace world, they expect the boxes to play through lightning on the power lines. Nothing is impossible to damage, but they can protect it through a lot of scenarios for not much money.
I could write a dissertation or two on “expensive cost savings.” Cost saving implementations that cause problems and ultimately cause cost increases.
Tesla did have the best powertrain (motor, battery, and electronics) of the electric vehicles mentioned.
The point of this post is mostly to criticize the arrogance of the Silicon Valley mindset when it comes to things that aren’t hip and cutting edge, like design for manufacturability and assembly. The “dinosaurs” of the engineering world.
If I wanted to make money with an electric car startup, I’d have my powertrain design team in Palo Alto and be hip kids from Cal Tech and MIT. I’d have the rest of the car designed in Detroit by a bunch of experienced automotive engineers from Michigan, Purdue, and RHIT. Then I’d have the whole thing assembled in Alabama or Texas in a non UAW factory.
The best powertrain, the most efficient monocoque and chassis, then the lost cost domestic assembly.
The “iPhone of cars” analogy is perfect in so many ways. Not just because of the engineering mindset but also for the fanboys that love their product even when you point out obvious flaws and how they always need to go out and buy the latest and greatest tech on the day it’s released.
Point of order. While one might not be able to upgrade an iphone, repair parts are available, and I’ve done such things as replace batteries and worn out power ports. Not for the faint of heart, though.
