Enhanced Autopilot on a HW4 2024 Model 3 - need your thoughts

Col127 | 2026-02-24 00:06 | 24 views

I was planning on buying a 2026 Juniper Model Y (LR AWD or Performance), transferring FSD from my 2018 Model 3 LR RWD (HW3)... BUT, a salesguy I know found a 2024 Model 3 HW4 with low mileage AND Enhanced AutoPilot (EAP) on it. The price difference between between a new Juniper to this used Model 3 HW4 is about $25k-30k - so I find myself being pulled because of the great price on the 2024 Model 3. I'm fine if I stay on a Model 3. I was wanting to have FSD lifetime, but that's not a thing anymore... and I actually don't drive my Model 3 that much either. Our main driver is a 2024 Ford Mustang Mach E since it's AWD and actually, it's way nicer than my 2018 Model 3. My question to you all: How does EAP perform on a HW4 car on highways? What's it like? Does it auto-lane change well? How does it behave? I don't need FSD on city streets - I never use it on my current Model 3, just on highways, so I'd like to know what the differences are from an owner who has EAP on a HW4 car. Thanks!!

AP/EAP hasn’t been updated in forever. The closest thing you’ll be able to use is smart summon which is based on V12

I’m on v12 on my 2018 Model 3, so that’d be the same. I never use smart summon. How does it drive on the highway? Is it similar to FSD?

try eap on your current model 3 then. it will be the same. IMO it is way worse than even v12

to clarify, since it hasn’t been updated in so long, eap is the exact same on HW3/4 and I think even HW2/2.5

Something I’m confused, so you have the 2018 M3 with FSD so instead of getting a new Juniper and transferring, you are thinking of getting a Model 3 HW4 with EAP? Then you’d prob sell the 2018 M3 right with FSD? I don’t know, doesn’t feel like you are getting a good deal by going with the car with EAP when you’ve already paid for FSD and can just transfer to the juniper. But I do get the money factory. But if you do the FSD transfer, you get a model y instead of older model 3 (non highland), Also, I don’t think 2024 Model 3 would come with EAP on HW4. I think EAP was on much older cars.

Juniper Model Y is very nice and much quieter and likely on par with your 2024 Mach E. That and HW4 FSD? I would test drive the 2026 Juniper first. I took the leap and I'm impressed.

Can I still use EAP on my model 3 if I have FSD? Don’t remember seeing an option for that? I’ll check it out tomorrow

If you have EAP, it brings the FSD subscription down to $49. You can buy many years of FSD with the savings.

Juniper is fantastic which is why I thought about upgrading, but I don’t think it’s $25k better than a 2024 model 3 . I could sub FSD FOR $49 a month, too if I got it. I’m curious how well EAP does

Col127 2026-02-24 03:45

yeah you have that right. its a difference of at least $25k for me which is why I’m thinking about it. if EAP on HW4 works fairly well on highways, I’m fine with it. don’t need to have FSD. i would lose lifetime FSD and have EAP instead on a much newer model 3 with AWD and warranty. though I could sub to FSD for $49 a month when needed.

Yeah I get it now. The difference in cost is significant. EAP might be better than the standard AP that used to come with Teslas. One thing I’m more concerned is if it actually comes with EAP, since it’s 2024 Model 3 and they didn’t offer EAP that time.

AP on a HW4 car is going to be the same as your 2018. It hasn’t been updated in forever. All EAP adds is lane changes. It’s no where close to FSD.

WhaleDonation7 2026-02-24 13:42

The model Y prices are a bit outrageous right now

Col127 2026-02-24 15:26

Looks like Tesla got rid of EAP in 2024, so it's possible that the 2024 Model 3 could have it. I'm asking the sales guy to send me a screen.

Col127 2026-02-24 15:26

Oh interesting, I thought it was on the same tech stack, but looks like it isn't.

I have an "Autosteer (beta)" option in my car. It actually recognizes traffic lights and will stop and resume driving at them, with parking assist, etc. Is this what EAP is referred to now? I actually thought it did a great job today when I drove. I was surprised that it recognized traffic lights.
