You’ve just stepped off the train at 30th Street Station or landed at PHL. The Philadelphia humidity is hitting you, and your family is standing next to a mountain of luggage. You’ve decided to go electric for your trip—smart move. But now you face the ultimate traveler’s riddle: which Tesla actually fits your life? At Frontier, we see this "luggage Tetris" play out every single day. You want the sleek efficiency of the Model 3, but you’re eyeing the Model Y’s hatchback and wondering if that extra rental cost is the price of your sanity.
Choosing between a Tesla Model 3 vs Model Y trunk space rental isn't just about looking at a spec sheet. It’s about knowing if that Uppababy stroller will actually let you close the trunk without a fight. We’ve spent hundreds of hours loading, unloading, and living with these cars in the narrow streets of Philly. Here is the ground-truth on which Frontier rental will actually fit your gear.
The Model 3 Reality Check: Can It Handle the "Stroller Plus Two" Test?
One of the most frequent questions we get at our downtown pickup locations is: Does the Model 3 trunk fit a stroller and two suitcases?
The short answer is yes, but there’s a strategy involved. The Model 3 offers approximately 15 cubic feet of space in the rear trunk, supplemented by a 3.1 cubic foot "frunk" (front trunk). However, the Model 3 is a sedan with a traditional trunk lid, not a hatchback. This means the opening is narrower than you might expect.
How to Pack a Model 3 for a Family of Three
In our testing, a standard full-size stroller (like a Mockingbird or a Vista) will fit comfortably if you remove the rear wheels or fold it flat. Once the stroller is in, you can fit two medium-sized (24-inch) checked suitcases on top or beside it.
Here’s the Frontier pro-tip: Use the sub-trunk. Beneath the main floor of the Model 3 trunk is a deep well. This is the perfect spot for your "soft" items—think diaper bags, backpacks, or that bag of Reading Terminal Market snacks you picked up. By utilizing the sub-trunk, you free up the main floor for the rigid items that won't compress.
Is the Model Y Worth the Extra Rental Cost for Cargo Space?
When you’re looking at your booking options, the Model Y usually carries a premium. You might ask: Is the Model Y worth the extra rental cost for more cargo space?
If you are a "heavy" packer or traveling with more than three people, the answer is a resounding yes. The Model Y isn't just a slightly larger Model 3; it’s a fundamentally different beast when it comes to utility. According to Tesla’s official specifications, the Model Y boasts 30.2 cubic feet of space behind the second row—more than double the Model 3’s trunk volume.
The Hatchback Advantage
The real value of the Model Y isn't just the volume; it’s the access. Because the Model Y is a hatchback, the entire rear glass lifts. This allows you to stack items vertically. If you have a double stroller, a set of golf clubs for a round at Walnut Lane, or large hardshell Pelican cases, the Model Y handles them without requiring a degree in engineering.
We’ve found that for groups of four, the Model Y eliminates the "luggage anxiety" that can dampen the start of a vacation. You aren't just paying for space; you’re paying for the ability to throw your bags in and go, rather than spending twenty minutes in a parking garage rearranging zippers.
The Four-Person Dilemma: Can You Fit 4 People and Luggage in a Model 3?
This is the "make or break" question for many small groups. Can I fit 4 people and luggage in a Model 3 rental?
Technically, the Model 3 seats five. However, when you have four adults, the trunk space becomes the bottleneck. If each person brings a "carry-on" sized suitcase (22x14x9 inches), the Model 3 is a dream. You can fit four carry-ons in the main trunk and use the frunk for everyone’s personal items or laptop bags.
When the Model 3 Becomes Too Tight
If those four people are bringing full-sized checked bags for a week-long stay in Rittenhouse Square, you’re going to have a problem. You might find yourself with a suitcase buckled into the middle seat between two passengers. That’s not the premium Frontier experience we want for you.
For four adults with standard luggage, we almost always recommend the Model Y. The extra headroom in the back seat also makes a significant difference for taller passengers navigating the bumps of Kelly Drive.
The "Frunk" Factor: Tesla’s Secret Weapon
Regardless of which model you choose, don't ignore the frunk. In a gas car, this is where the engine lives. In a Tesla, it’s a clean, plastic-lined sanctuary for things you don't want near your main luggage.
- Model 3 Frunk: Great for a grocery bag, a charging cable, or a small gym bag.
- Model Y Frunk: Noticeably deeper. It can easily hold a standard grocery bag full of supplies or two pairs of hiking boots.
We’ve seen savvy renters use the frunk as a "takeout zone." If you’re picking up a hot pizza from Angelo’s Pizzeria, put it in the frunk. It keeps the smell out of the main cabin and keeps the boxes flat.
Navigating Philly: Size vs. Space
There is one area where the Model 3 wins: the "Philly Squeeze." If your rental involves navigating the tiny, cobblestone streets of Old City or finding street parking near Passyunk Avenue, the Model 3’s smaller footprint is a blessing.
The Model 3 is about 2 inches narrower and 7 inches shorter than the Model Y. In the world of Philadelphia parallel parking, 7 inches is the difference between "I fit" and "I have to circle the block for another hour."
Key Takeaways for Your Frontier Rental
Before you click "book," run through this quick checklist we’ve developed for our customers:
- The Stroller Rule: Single stroller? Model 3 is fine. Double stroller? You need the Model Y.
- The Bag Count: More than two large checked bags? Go with the Model Y.
- The Passenger Comfort: If your rear-seat passengers are over 6 feet tall, the Model Y’s higher roofline will prevent many complaints.
- The "Self-Driving" Experience: Both models at Frontier come self-driving capable. The tech is the same; only the tin is different.
Technical Comparison: By the Numbers
| Feature | Tesla Model 3 | Tesla Model Y |
|---|---|---|

| Front Cargo (Frunk) | 3.1 cu ft | 4.1 cu ft |
| Total Max Volume | 22.9 cu ft (seats down) | 76.2 cu ft (seats down) |

| Opening Style | Traditional Trunk | Power Hatchback |
Understanding the Sub-Trunk and Side Pockets
Both vehicles feature hidden storage that most renters overlook. When you open the trunk of your Frontier Tesla, look for the floor handle. Lifting this reveals the sub-trunk.
In the Model Y, this sub-trunk is massive—large enough to hold a carry-on bag entirely out of sight. The Model Y also features deep side pockets behind the wheel wells. These are perfect for securing wine bottles from a local PA Fine Wine & Good Spirits or keeping your charging adapters from rolling around.
Why Downtown Pickup Changes the Game
At Frontier, we focus on downtown pickups because we know you don't want to trek back to the airport. But picking up a car in a city center means you’re often loading your luggage on a busy street.
The Model Y’s power liftgate is a lifesaver here. You can trigger it from the Tesla app as you approach with your hands full of bags. The Model 3 trunk is also powered, but the smaller opening means you have to be more deliberate with your movements to avoid blocking the sidewalk.
Addressing Common Objections: "Is the Model Y too big to drive?"
Some drivers worry that moving up to the Model Y will make them feel like they’re driving a bus. It doesn't. Because Tesla places the heavy battery pack at the bottom of the car, both vehicles have a very low center of gravity.
The Model Y handles with surprising agility. While it’s taller, it doesn't have the "body roll" you’d expect from a traditional SUV like a Chevy Tahoe. If you can drive a Honda Accord, you can drive a Model Y. Don't let the fear of size keep you from the storage space you actually need.
The Verdict: Which One Should You Book?
I’ve found that most people underestimate their luggage. We want to be the "light traveler" who fits everything into a backpack, but reality usually involves an extra "just in case" bag.
Choose the Model 3 if: You are a couple or a solo traveler, you’re staying in a part of Philly with notoriously tight parking, and you value range efficiency and a sporty "cockpit" feel.
Choose the Model Y if: You have kids, you have a stroller, you’re traveling as a group of four, or you simply don't want to think about whether your shopping spree at King of Prussia Mall will fit in the back.

Yes, a single compact or mid-size stroller will fit along with two medium suitcases, provided you utilize the sub-trunk for smaller items.
