Just sharing my experience: I went through this last year when I first got my Q8 e-tron. I'm kinda obsessed with the technical specs of the trunk dimensions, and I realized that while those pricey Audi bins are cool, they dont always maximize the floor's square footage for the price.

I actually ended up testing a few budget-friendly setups to see what stayed put during heavy regen braking. Honestly, I found that mixing two different sizes worked best for my cables and groceries:

* TrunkCrrate Pro Collapsible Multi Compartment Car Organizer - This one is super sturdy and basically fits perfectly on one side without blocking the latch for the under-floor storage.
* Starling's Car Trunk Organizer with Adjustable Straps - I like this because it has a high-friction bottom that actually sticks to the Audi carpet texture pretty well.

Basically, I saved about 60 bucks compared to the OEM stuff and it's been working great. Plus, the black fabric lowkey matches the premium interior vibes anyway. gl with the setup!

Just sharing my experience: I did a deep dive into this when I got my e-tron because honestly, the Audi OEM stuff feels a bit overpriced for what it is. I compared a few market leaders and ended up with the Starling's Car Trunk Organizer Adjustable 3 Compartments.

I mean, basically here is how I saw it:

* **Premium Vibe:** The Rola 59001 M.O.V.E. Rigid Base Trunk Organizer is super sturdy but kinda heavy.
* **Best Fit:** The Starling's fits the Q8's depth perfectly and doesn't block the under-floor latch.

Ur gonna love having things not sliding around when you hit that instant torque lol. It's SO much better.

In my experience, you gotta be careful with generic bins cuz they slide and scratch the trim. I’ve used the Audi Genuine Accessories 8U0061108 Collapsible Trunk Box for years... it’s sturdy and doesn't block the floor latch if you place it right. Honestly, sticking with OEM is usually safer for the fit tbh. It matches the interior vibe perfectly too! gl!

In my experience, since you're driving a high-end EV like the Q8 e-tron, you really want something with a rubberized or high-friction base so it doesnt slide during that instant torque acceleration. For your situation, I would suggest looking at the Fortem Car Trunk Organizer with Reinforced Base and Non-Slip Strips. It’s basically a tank.

What’s cool about this one is the modularity—you can secure it using the tie-down hooks in your Audi's trunk so it stays put while you're cornering, but it’s light enough to just slide over when you need to lift the floor panel for your charging cables. Honestly, I’ve tried the generic bins from big box stores and they literally just scuff the side trim. This one has soft sides but a rigid structure. Another solid technical pick is the Drive Auto Car Trunk Organizer and Storage with Securing Straps. It has those reinforced plates that keep it from collapsing when it's half-empty. Ngl, it makes the trunk look much cleaner than just tossing stuff in there. gl!

I totally get the struggle... I actually spent a weekend trying to DIY a custom wooden divider for my Q8 e-tron but it ended up being way too heavy and rattled like crazy. I scrapped that and looked for something modular instead. What worked for me was using the Home-Complete Car Trunk Organizer with Tie Down Straps and actually hooking it into the built-in Audi D-rings in the trunk floor. Since the e-tron has those nice mounting points, you can secure it so it stays right near the side wall. That way, the center floor panel for the under-storage is still totally accessible without moving the whole box. A few things I learned from my trial and error:

• Use the bungee straps it comes with to keep it from sliding during that EV torque.
• Put your charging cables in the side mesh pockets to keep the main bins free for groceries.
• If you get one with a lid, it hides the cable clutter way better and looks much cleaner thru the back window. Basically, dont overthink the custom fit, just find something that uses those factory anchor points!

> Has anyone found a specific brand or custom-fit option that matches the premium interior well? I saw this earlier and wanted to share what has worked for me over the last year of ownership. Finding something that matches the e-trons build quality is tricky, but I have been very satisfied with the Knodel Car Trunk Organizer with Lid Heavy Duty. It actually looks like it belongs in a high-end cabin. The lid is the main selling point for me. It keeps my Level 1 charger and tools out of sight, maintaining that clean look. I positioned it on the far left side, which ensures I can still lift the trunk floor to reach the lower compartment without having to move the organizer at all. Another one I tested was the Lusso Gear Car Trunk Organizer with Securing Straps. It is quite sturdy and the materials feel premium to the touch. It has these reinforced handles and straps that hook directly into the Audi cargo loops. If you want something that literally wont budge during spirited driving, that is the one. No complaints with either, though the Knodel fits my workflow a bit better since I prefer the hidden storage vibe... just keeps everything looking tidy.

Gonna try this over the weekend. Will report back if it works!

Can confirm
