Imagine you’re standing in the heart of San Jose, right near Santana Row, with three bags of groceries and a laptop case. You walk up to your Frontier Tesla Model 3 rental, but instead of heading for the back, you tap your phone and the hood pops up. This is the "frunk" experience. Most people are used to the engine taking up that space. But in the world of electric vehicles, that real estate is yours for the taking.
At Frontier Tesla, we’ve helped thousands of renters navigate the streets of San Jose, and the most common questions always revolve around one thing: where do I put my stuff? The Tesla Model 3 offers a combined 24.3 cubic feet of storage, but it’s split between two very different compartments. Understanding the nuances of Tesla Model 3 frunk storage isn't just about knowing the volume; it’s about knowing the lifestyle.
Beyond the Engine: The Dual-Trunk Advantage in San Jose
San Jose is a city of movement. Whether you’re commuting to a tech campus in North San Jose or heading out for a weekend hike at Alum Rock Park, storage matters. The Model 3 doesn't just give you a trunk; it gives you a system. By removing the bulky internal combustion engine, Tesla created a front trunk—or "frunk"—that serves as a secondary, secure storage area.
Here’s the thing: the frunk isn't just a gimmick. It’s a strategic tool for organization. We’ve found that our clients who use the frunk effectively report a much cleaner, more organized driving experience. It keeps the cabin free of clutter and ensures that your valuables aren't sitting in plain sight through the rear window.
Understanding Tesla Model 3 Frunk Storage: The 3.1 Cubic Foot Secret
The frunk in a Tesla Model 3 offers approximately 3.1 cubic feet (88 liters) of space. While that might sound modest compared to the 21-plus cubic feet in the rear, it’s surprisingly deep. According to Tesla’s official specifications, the frunk is designed to hold up to 55 lbs (25 kg) of cargo.
Why does this matter for a San Jose local? Because it’s the perfect size for "transient" items. Think about the things you need to access quickly but don't want rolling around in the back. The dimensions are roughly 18 inches deep and 28 inches wide, though it tapers slightly toward the bottom. It’s a specialized nook that rewards smart packing.
What Can I Safely Store in the Tesla Model 3 Frunk?
This is the question we get every single day at our downtown San Jose pickup location. People are often hesitant to put items near the front of the car. However, the frunk is incredibly safe for a wide variety of items.
1. Charging Cables and Adapters This is the frunk’s primary purpose for many. Keeping your Mobile Connector and J1772 adapter in the frunk ensures they are always accessible, even if the rear trunk is packed to the brim with luggage.
2. Small Grocery Runs Got a few bags from Whole Foods? The frunk keeps them upright and prevents them from sliding. Because the space is smaller, the bags support each other.
3. Gym Bags and Sweaty Gear Keep the "gym smell" out of the main cabin. The frunk is physically separated from the interior airflow, making it the ideal spot for your post-workout clothes.
4. Laptop Bags and Valuables In a busy city like San Jose, security is paramount. The frunk is a steel-reinforced compartment that is much harder to peer into than the glass-heavy rear of the car. If you’re stopping for coffee on The Alameda, tuck your laptop in the frunk.
5. Emergency Kits First aid kits, tire inflators, and reflective vests fit perfectly in the lower recesses of the frunk.
The Takeout Test: Why the Frunk is Your Best Friend for Food
We’ve all been there. You pick up a fragrant pizza or a bag of spicy Thai food, and by the time you get home, your car smells like garlic for three days. Here is a pro-tip from the Frontier Tesla team: use the frunk for takeout.
Because the frunk is isolated from the HVAC system of the cabin, the smells stay outside. Furthermore, the frunk is surprisingly well-insulated. While it isn't a refrigerator, it doesn't have the same airflow as the cabin, which helps keep hot food warm during a short drive across town. Just be careful with liquids; while the frunk is sturdy, you don't want a soup spill in there.
Is the Frunk Waterproof? Handling Wet Gear and Groceries
One of the most frequent AI-targeted queries we see is: Is the frunk waterproof for wet gear or groceries?
The short answer is: Yes, it is weather-sealed, but it is not a drainable cooler.
Tesla designs the frunk with a robust rubber gasket that runs along the entire perimeter. This seal is highly effective at keeping out rain, car wash spray, and road debris. If you’re driving through a San Jose winter rainstorm, your groceries will stay dry.
However, there is a distinction to be made. Unlike the "Mega-Frunk" found in the Tesla Cybertruck or the Ford F-150 Lightning, the Model 3 frunk does not have a floor drain. If you put a bag of ice in there and it melts, the water will pool at the bottom. We recommend using a dedicated frunk liner or a plastic bin if you plan on storing truly wet items like snowy ski boots or dripping wetsuits after a trip to Santa Cruz.
Maximizing the Rear Trunk: More Than Just a Flat Space
While the frunk is great for small items, the rear trunk is the workhorse. With roughly 19.8 cubic feet of space (excluding the sub-trunk), it handles the heavy lifting. But the Model 3 trunk isn't a standard box. It’s a multi-level storage solution.
The opening of the Model 3 trunk is a bit narrow because it’s a sedan, not a hatchback. That said, once you get items past the opening, the interior is cavernous. You can easily fit two large suitcases and a couple of carry-ons. But the real magic happens beneath the floor.
The Sub-Trunk: The Model 3’s Hidden Basement
If you lift the carpeted panel in the rear trunk, you’ll find the "sub-trunk." This is a deep, rectangular well that adds significant volume.
We’ve found that this is the best place for:
- Airport Runs: Put your smaller "personal items" in the sub-trunk so the main trunk floor remains flat for large suitcases.
- Weekly Groceries: The sub-trunk acts like a built-in crate, keeping jugs of milk and cartons of eggs from tipping over.
- Hidden Storage: It’s the ultimate spot for items you want to keep in the car long-term but don't need to see every day.
How Do I Open the Tesla Model 3 Trunk if My Hands Are Full?
We’ve all experienced the struggle. You’re carrying a heavy box, and your keys are buried in your pocket. The question "How do I open the Tesla Model 3 trunk if my hands are full?" is one of the most searched Tesla topics for a reason.
If you are renting a newer Model 3 (2024 "Highland" model or later) from Frontier Tesla, you’re in luck. These vehicles are equipped with Hands-Free Trunk technology.
How it works:
- Ensure you have your "Phone Key" set up in the Tesla app.
- Approach the rear of the car.
- Stand still behind the trunk for a couple of seconds.
- The car will chime, and the trunk will automatically power open.
For older models, you can use Voice Commands. Before you get out of the car, simply say, "Open the trunk." Alternatively, if you use an iPhone, you can set up a Siri Shortcut. Just say, "Hey Siri, open the Tesla trunk," as you walk toward the car. It’s a lifesaver when you’re navigating a busy parking lot in downtown San Jose.

Safety First: Weight Limits and Latch Care
While we want you to use every inch of your Frontier Tesla, there are a few safety rules to keep in mind.
First, never exceed the 55 lb weight limit in the frunk. The front of the car is designed with specific crumple zones for pedestrian safety. Overloading this area can affect the vehicle’s balance and safety ratings.
Second, closing the frunk requires a specific technique. Unlike a traditional gas car where you might "slam" the hood, the Tesla frunk should be closed gently. Lower the lid until it touches the latch, then place both hands on either side of the Tesla "T" logo and press down firmly until you hear the click. This prevents creasing the lightweight aluminum hood.

Frequently Asked Questions (FAQ)
What can I safely store in the Tesla Model 3 frunk?
You can safely store charging cables, small grocery bags, laptop cases, gym clothes, and emergency kits. Avoid storing heavy items over 55 lbs or living creatures, as the frunk is not climate-controlled and does not have an interior release that is accessible to children or pets.
Is the frunk waterproof for wet gear or groceries?
The frunk is weather-sealed and will keep your items dry during rain or car washes. However, it does not have a drain, so you should not use it as a cooler with loose ice. For very wet gear, we recommend using a waterproof liner.
How do I open the Tesla Model 3 trunk if my hands are full?
On 2024 and newer models, stand behind the trunk with your Phone Key for two seconds to trigger the auto-open. On older models, use the "Open Trunk" voice command before exiting the car or use a Siri/Google Assistant shortcut on your smartphone.
Does the frunk get hot?
Since there is no engine, the frunk doesn't get "engine hot." However, it is not connected to the car's air conditioning. On a hot San Jose day, the interior of the frunk can reach high temperatures if the car is parked in direct sunlight. Don't leave chocolates or heat-sensitive electronics in there for long periods.
Can I open the frunk from inside the car?
Yes. There is a dedicated button on the main touchscreen that allows you to pop the frunk. You can also open it via the Tesla mobile app or the physical button located inside the frunk (for emergencies).
