A few people have reached out since this post asking how to actually identify the hardware in practice, which screen to look at, what to
look for, how to tell HW3 from HW4 when you're standing on a lot
evaluating a trade.
Since I get this question a lot, I'll share what I built to solve it
for myself and I'd genuinely love feedback from people who work
with these cars every day.
Two screens on the Tesla's own touchscreen tell you everything:
1. Tap the car icon (bottom left), scroll to Software. This shows
the AI Computer generation (HW3 vs HW4), FSD status (whether it
was purchased outright or is on subscription), and the software
version.
2. On that same page, tap the blue "Additional Vehicle Information"
link. This shows the MCU chip (Intel Atom vs AMD Ryzen), plus
options like tow package, HEPA filter, and rear-facing seats.
Those two screens tell you what KBB, Carfax, and the VIN decoder
can't, and they're right there on every Tesla, no tools required.
I got tired of explaining this manually so I built a tool that reads
both screens from photos and returns a hardware-adjusted valuation automatically. Takes about 60 seconds per car.
Here's where I'd genuinely value input from dealers who actually
work this market:
- Does the valuation output give you something useful at the point
of acquisition or pricing, or does it need to present differently
to fit how you actually work?
- What's missing that would make this more useful on your lot?
- Are there hardware configurations you're seeing in the wild that
you think we're not accounting for?
If you want to try it on your own inventory and share what you find
go to
wattmatters.ai/trial and enter code DEALERREFRESH. Free 15-day access, no credit card. I'm less interested in converting anyone
right now than in getting honest feedback from people who see more Teslas in a week than most people see in a year.
