You’ve just landed at San Diego International Airport. The sun is blazing, the Pacific breeze is calling, and you have a reservation for a self-driving-capable Tesla from Frontier Tesla. But as you stand at the downtown pickup point, looking at the sleek silhouettes of the Model 3 and the Model S, a practical question hits you. Will all that beach gear actually fit?
We’ve seen it a thousand times. A family of four arrives with two oversized coolers, three boogie boards, a collapsible sun canopy, and enough sand-encrusted towels to carpet a small apartment. They want the efficiency of the Model 3 but fear the "Tetris" struggle of a traditional trunk. Or they eye the Model S, wondering if the premium price tag translates into actual, usable "beach utility."
Choosing between these two EVs isn't just about 0–60 times or Autopilot versions. In San Diego, it’s about the trunk. Specifically, it’s about how easily you can transition from a downtown pickup to the shores of La Jolla without leaving your favorite beach chair behind.
The Aperture Argument: Liftgate vs. Traditional Trunk
Here is the fundamental difference that changes everything for a San Diego renter. The Tesla Model S features a liftgate (hatchback), while the Model 3 utilizes a traditional sedan trunk.
Does the Model S liftgate make it easier to load beach gear than the Model 3 trunk? Absolutely. Think of the Model S as a cavernous maw. When that rear glass lifts, the entire cargo area is exposed. You aren't sliding items into a hole; you are placing them onto a platform.
In contrast, the Model 3 has a "letterbox" opening. While the interior volume is impressive, the physical dimensions of the opening are restrictive. If you have a rigid, wide item—like a large hard-shell cooler or a folded-up beach wagon—you might find yourself tilting, rotating, and swearing as you try to clear the trunk's lip.
I’ve found that the Model S saves roughly five minutes of "cargo Tetris" every time you hit the beach. That’s five more minutes of surfing. Or five more minutes of hunting for parking at Pacific Beach.
Tesla Model 3 vs Model S Trunk Space: The Raw Numbers
To understand the utility, we have to look at the data. According to Tesla’s official specifications for 2024 models, the Model S offers approximately 25 cubic feet of rear cargo space. When you fold the seats down, that expands to a massive 61.4 cubic feet.
The Model 3 is no slouch, but it plays in a different league. It offers about 19.8 cubic feet of rear cargo space. Even with its recent "Highland" refresh, the total volume remains significantly lower than its larger sibling.
But numbers can be deceptive. Here’s the thing: beach gear is rarely "liquid." It doesn't fill every cubic inch perfectly. You’re dealing with awkward shapes. The Model S’s extra width (about 4 inches wider than the Model 3) is often the deciding factor for whether a beach umbrella can lay horizontally or needs to be angled across the backseat, sacrificing a passenger's legroom.
Which Tesla Has More Usable Storage for Sandy Beach Gear?
When we talk about "usable" storage, we’re talking about the "Sand Factor." San Diego sand is relentless. It gets into every crevice.
The Model S wins on pure volume, but it also wins on layout. The floor is flatter and wider. This allows you to create a "wet zone" and a "dry zone" more effectively. We recommend placing a heavy-duty tarp across the Model S floor. Because the opening is so wide, you can shake out the tarp much easier than you could in the deep, recessed well of the Model 3.
However, the Model 3 has a secret weapon. Its trunk is surprisingly deep. If you are packing soft items—bags of clothes, towels, or inflatable toys—you can stack them remarkably high. But for the heavy hitters like the 10x10 pop-up tents common at Mission Beach? The Model S is the undisputed champion.
Wet Towels and the Sub-Trunk Solution
This brings us to one of the most common questions we get at Frontier Tesla: Is the Model 3 sub-trunk useful for storing wet beach towels?
Yes, and it might be the car’s best feature for coastal travelers. Underneath the main floor of the Model 3 trunk is a deep, plastic-lined well. It’s essentially a "basement" for your car.
What we’ve learned is that this space is perfect for the "soggy stuff."
- The Wet Towel Strategy: Instead of letting damp, salty towels sit on your upholstery, fold them into the sub-trunk.
- Containment: The sub-trunk acts as a natural barrier, keeping moisture away from your dry bags.
- Easy Cleanup: Since the walls of the sub-trunk are rigid and often easier to wipe down than the carpeted main floor, it’s the ideal spot for sandy flip-flops and snorkel fins.
The Model S also has a sub-trunk, and it is wider but shallower than the Model 3’s. While it holds more total volume, the Model 3’s "deep well" design feels more secure for containing liquids or loose sand.
The Frunk Factor: Front Storage for Small Essentials
Don't forget the "frunk" (front trunk). Both cars have them, but they serve different purposes for a beach day.
The Model S frunk is roughly 3.1 cubic feet. It’s wide and flat. It’s the perfect spot for your "valuables" that you don't want buried under a pile of boogie boards in the back. Think cameras, wallets, and dry changes of clothes.
The Model 3 frunk is slightly smaller (around 3.1 cubic feet as well, but shaped differently). It’s deeper and narrower. We’ve found it’s the best place to store your charging cables and a small emergency kit, leaving the rear entirely for recreation.
Long Gear Logistics: Surfboards and Boogie Boards
San Diego is a surf town. If you’re renting a board from a shop in Encinitas, how are you getting it to the water?
The Model S is long. Very long. With the 60/40 split-folding seats, you can easily slide an 8-foot longboard through the trunk and up between the front seats. Because of the liftgate, the angle of entry is shallow. It’s a smooth slide.
The Model 3 can also handle boards, but the "hump" between the trunk and the cabin is more pronounced. You’ll find yourself lifting the board up and over the rear seat anchors. It’s doable, but it requires more muscle and more care to avoid scuffing the premium interior.
Real-World Scenario: The "Windansea" Test
Imagine you’re heading to Windansea Beach. Parking is notoriously tight. You need to get in, get out, and get your gear on the sand fast.
In a Model 3, you’ll likely have your gear stacked high. You open the trunk, and a rogue volleyball falls out. You reach deep into the "cave" to find your sunscreen. It’s a bit of a scramble.
In a Model S, you pop the liftgate. Everything is laid out like a buffet. You grab your chair, your cooler, and your board in one fluid motion. The Model S doesn't just offer more space; it offers better access to that space. For a luxury rental experience, that ease of use is worth the upgrade.

Frequently Asked Questions
Which Tesla has more usable storage for sandy beach gear?
The Model S has more usable storage due to its wider floor and liftgate opening. While the Model 3 is efficient, the Model S allows for larger, bulkier items like hard-shell coolers and wide beach wagons that simply won't fit through the Model 3's trunk opening.
Is the Model 3 sub-trunk useful for storing wet beach towels?
Yes, it is highly effective. The deep, recessed design of the Model 3 sub-trunk allows you to isolate damp, sandy items from the rest of your luggage. It prevents salt water from soaking into the main trunk carpet and keeps the cabin smelling fresher.
Does the Model S liftgate make it easier to load beach gear than the Model 3 trunk?
Significantly. The liftgate removes the "overhead" obstruction found in the Model 3. This allows you to drop items straight down into the cargo area rather than sliding them in horizontally, which is much easier when handling heavy or awkwardly shaped beach equipment.
Can I fit a full-size stroller and beach gear in a Model 3?
It’s a tight fit. You will likely need to remove the wheels from the stroller or use the sub-trunk for smaller bags to make it work. In a Model S, a full-size stroller usually fits comfortably alongside a medium cooler without any disassembly.
Final Verdict: Which Should You Rent?
If you are a solo traveler or a couple with light gear—a few bags and some towels—the Model 3 is a fantastic, sporty choice. Its sub-trunk is a genius bit of engineering for managing the mess of a beach day.
But if you are a family, or if you plan on bringing the "full setup" (chairs, umbrellas, coolers, boards), the Model S is the superior tool for the job. The liftgate isn't just a luxury; it’s a utility powerhouse that makes every transition of your San Diego vacation smoother.
At Frontier Tesla, we provide both. Our downtown pickup locations mean you can grab your car and be at the beach in minutes. Whether you choose the nimble Model 3 or the spacious Model S, you’re getting a self-driving-capable vehicle that’s ready for the Pacific coastline.
