This video came up on my YouTube feed this morning and I found it interesting, so I thought I'd share it here.

Hardware 3 vs Hardware 4 (Video)

Really only showing the difference in the cameras..
And higher res cameras need more processing power to interpret them, hence HW4.
Teardowns by people like greentheonly have shown HW4 is a different form factor with different mounting points and connectors, so not upgradeable in current form.

@Petros my M3P is the same age as yours, Dec, 2019. While I would love to be able to get some upgrades, I've resigned myself to accepting the car as it is and waiting for something compelling to upgrade to. My car is still in excellent shape after ~56,000 km, so the existing M3 or MY options are not compelling enough.
The one thing that Tesla could do that might entice me is ventilated seats. The upgraded MCU, HW4 cameras, powered boot, etc. are nice to have, but the ventilated seats would change my driving experience.

Elon has said it is not possible to upgrade from HW3 to HW4 due to different form factor etc etc.
I don't really care about FSD until I can sit in the back and drink a beer while the car drives itself
Interested in your view about ventilated seats. Is it for the heat where you live?

I just went from HW3 to HW4 and to be honest this video doesn’t do it justice, the difference in quality is startling.
The seats just don't breathe. If I'm wearing a long sleeve business shirt and jeans then I have to keep the AC on <=21C. If it's on a warm day (> 28C) I'll still have a wet back after a trip from the Gold Coast to Brisbane and the AC on.
@louco73 you’ve done about 1k more than me. But unlike you I’m more interested in the way the car performs.
I recently had to drive manually on a motorway as the wipers were going crazy and I was reminded how much AP relieves a lot of the cognitive load. I want it to work better.
Yes, I believe its because the covers are made of plastic (the so called vegan leather
)Also HW4 appears to have downgraded specs in some areas vs HW3.

The sensors is one thing but also the shift to 50 TOPs vs 36 TOPs. Plus have dual processing where redundant units process then error handled on any difference in output.
Rumours persist that HW5 though will be needed for top shelf full self driving. HW5 is apparently well underway in design.

SAE L5. News/rumours suggested it's HW5 and apparently they are being held up by compute power constraint limits despite the huge amount that went into moving Dojo into production in July
