Imagine landing at Milwaukee Mitchell International Airport (MKE) on a crisp autumn morning. You’ve got your itinerary set: a morning coffee in the Third Ward, a stroll through the Milwaukee Art Museum, and maybe a late dinner near the Deer District. But as you stand at the luggage carousel, watching four massive hardshell suitcases tumble toward you, a sudden realization hits. Will all of this actually fit in the Tesla you just booked?
At Frontier Tesla, we see this scenario play out every week. Choosing between a Model 3 and a Model Y isn't just about the driving range or the sleek silhouette. For most travelers visiting the Cream City, the decision boils down to one practical, often overlooked factor: the trunk.
Here’s the thing. While both vehicles share a similar design DNA, their approach to storage is fundamentally different. One is a precision-engineered sedan; the other is a versatile compact SUV. Understanding the nuances of Tesla Model 3 vs Model Y trunk space is the difference between a seamless pickup and a stressful game of Tetris on the sidewalk.
The Raw Data: Comparing the Cubic Footage
When we look at the official specs, the gap between these two vehicles seems wide. According to Tesla’s 2024 technical specifications, the Model 3 offers approximately 19.8 cubic feet of total cargo space when you combine the rear trunk and the front trunk (the "frunk"). On the other hand, the Model Y boasts a massive 30.2 cubic feet behind the second row.
But numbers on a spreadsheet don't tell the whole story. I’ve found that how that space is shaped matters far more than the raw volume. The Model 3 is a traditional sedan with a fixed rear parcel shelf. This means you are limited by the height of the trunk opening. Conversely, the Model Y is a hatchback. When you open that rear liftgate, the entire back of the car becomes accessible.
The Model 3 Trunk: More Capable Than It Looks
Don't dismiss the Model 3 too quickly. It’s a common misconception that sedans can’t handle serious luggage. The Model 3 trunk is surprisingly deep. It extends far back toward the rear seats, allowing you to slide in long items with ease.
We often tell our clients that the Model 3 is perfect for "linear" packers. If you have standard-sized suitcases that can lay flat, you’ll be impressed by how much it swallows. However, the trunk opening is the bottleneck. If your gear is bulky or oddly shaped—think a jogging stroller or a large cooler for a tailgate at American Family Field—you might struggle to clear the lip.
Is the Model Y Trunk Significantly Larger than the Model 3?
This is the question we get most often at our downtown Milwaukee pickup location. The short answer? Yes, but specifically in terms of verticality.
If you are measuring from the floor to the ceiling, the Model Y wins by a landslide. Because it lacks the fixed shelf of the Model 3, you can stack items. This is a game-changer for families. In a Model 3, once you hit the top of the trunk lid, you're done. In a Model Y, you can keep piling gear until you've obscured the rearview mirror (though we don't recommend that for safety).
A 2023 independent test by Car and Driver found that while the Model 3 could hold seven carry-on suitcases in its trunk, the Model Y managed to fit fifteen with the rear seats stowed. Even with the seats up, the Model Y’s ability to accommodate taller items makes it feel significantly larger in practice.
The 4-Suitcase Challenge: Which Tesla Rental is Better?
Let’s get specific. You’re a family of four. You’ve each brought a full-sized checked bag. Which car should you rent?
In our experience at Frontier Tesla, the Model Y is the clear winner for a family with 4 suitcases. Here is why. To fit four large bags in a Model 3, you have to be a master of spatial geometry. You’ll likely have to use the "sub-trunk"—a deep well located under the main floor of the trunk—for one bag, then stack the others perfectly. It’s tight.
In the Model Y, those same four suitcases fit comfortably. You can stand them up on their sides or stack them two-by-two. This leaves the frunk and the sub-trunk completely free for your smaller carry-ons, backpacks, or that bag of cheese curds you picked up at the market.
The Secret Weapon: The Tesla Sub-Trunk
Both the Model 3 and Model Y feature a "hidden" storage compartment beneath the main trunk floor. This is where Tesla hides the charging cables, but there’s plenty of extra room.
In the Model Y, this sub-trunk is cavernous. It’s deep enough to hold a standard carry-on bag entirely out of sight. We’ve found that travelers love this for security. If you’re stopping for lunch at Leon’s Frozen Custard and don't want your valuables visible through the windows, the sub-trunk is your best friend. The Model 3 has a sub-trunk too, but it’s shallower and better suited for laptop bags or groceries.
Don't Forget the Frunk
One of the perks of renting an EV from Frontier Tesla is the front trunk. Since there’s no internal combustion engine taking up space under the hood, you get an extra storage cubby.
The frunk sizes are relatively similar between the two models, but the Model Y’s frunk is slightly deeper. It’s the perfect spot for items you want to keep separate from your main luggage—like gym shoes, charging adapters, or takeout food that you don't want smelling up the cabin.
Passenger Comfort vs. Cargo Capacity
When you’re deciding which rental is better for your Milwaukee trip, consider the passengers too. The Model Y isn't just bigger in the back; it’s taller throughout.
The Model Y offers "stadium seating," meaning the rear passengers sit higher up than those in the front. This provides more legroom and a better view. If you’re traveling with teenagers or adult friends, the Model Y’s extra headroom makes a long drive out to Kohler or Madison much more pleasant. The Model 3 is sportier and lower to the ground. It feels like a cockpit. It’s fun to drive, but if your passengers are tall, they might feel a bit cramped if the car is also packed to the gills with gear.
Navigating Milwaukee: Size Matters for Parking
While the Model Y wins on space, the Model 3 has an advantage in the tight streets of downtown Milwaukee. If you’re planning on parking in the older garages near the Historic Third Ward, you’ll appreciate the Model 3’s smaller footprint.
The Model 3 is easier to maneuver into narrow spots. That said, both cars come equipped with Tesla’s advanced camera systems and proximity sensors. Even in the slightly wider Model Y, parking is a breeze thanks to the bird's-eye view and Autopark features available on our self-driving-capable fleet.
Winter in MKE: Handling the Gear
If you’re visiting Milwaukee in the winter, your storage needs change. You aren't just carrying suitcases; you’re carrying heavy coats, boots, and maybe even a pair of skis.
The Model Y’s "40/20/40" split-folding rear seats are a major advantage here. You can fold down just the middle section to slide in skis or a snowboard while still seating two people comfortably in the back. The Model 3 has a standard 60/40 split, which is less flexible for long, narrow winter gear.
Key Takeaways for Your Tesla Rental
To help you decide, we’ve summarized the main points we discuss with our clients:
- Choose the Model 3 if: You are a solo traveler or a couple, you prefer a sporty driving feel, and you have standard-sized luggage.
- Choose the Model Y if: You are traveling with a family, you have more than three large suitcases, or you need to carry bulky items like strollers or sports equipment.
- The "Hatch" Factor: The Model Y’s liftgate makes loading and unloading significantly easier on your back.
- Visibility: The Model Y offers a higher seating position, giving you a better view of the road—a plus when navigating unfamiliar MKE intersections.
Should I Rent a Model 3 or Model Y for My Milwaukee Trip?
Ultimately, the choice depends on your specific needs. If you want the most efficient, "fun-to-drive" experience and your luggage is modest, the Model 3 is an incredible machine. It’s the car that redefined the electric sedan.
However, for 90% of the families we serve at Frontier Tesla, we recommend the Model Y. The peace of mind that comes with knowing "everything will fit" is worth the slight premium. You don't want to spend your vacation worrying about whether you can fit that souvenir from the Harley-Davidson Museum in the trunk.
FAQ: Your Tesla Rental Questions Answered
Is the Model Y trunk significantly larger than the Model 3?
Yes. While the floor dimensions are somewhat similar, the Model Y's hatchback design and lack of a rear parcel shelf allow for much more vertical storage. It offers about 50% more total cargo volume than the Model 3.
Which Tesla rental is better for a family with 4 suitcases?
The Model Y is significantly better. It can accommodate four large suitcases without requiring the complex "stacking" needed in the Model 3. Plus, the Model Y's sub-trunk can hide an additional carry-on bag.
Can I fit a stroller in a Model 3?
A compact "umbrella" stroller will fit easily. However, a full-sized jogging stroller can be difficult to get through the Model 3's narrow trunk opening. For families with young children, we always suggest the Model Y.
Does the Model Y have more legroom?
Yes. The Model Y has more rear legroom and significantly more headroom than the Model 3, making it the better choice for groups of four or five adults.
