Over the past decade, the electric vehicle revolution has transformed how we think about mobility, efficiency, and vehicle architecture. One quirky yet increasingly valued byproduct of this transformation is the frunk—a front trunk storage space where, in internal combustion engine (ICE) vehicles, you’d typically find an engine.

While the frunk was once dismissed as a novelty, it’s now becoming a central part of the EV storage conversation. Some manufacturers are turning this small innovation into a major selling point. But why do EVs have frunks in the first place? And more importantly, which EVs actually make them functional for real-world usage?

Let’s dive deep into the engineering logic, usability, and best implementations of the frunk—separating gimmick from game-changer.

What Is a Frunk, and Where Did the Idea Come From?

The word “frunk” is a portmanteau of “front” + “trunk.” It refers to the additional cargo space in the front section of a vehicle, where a traditional gas car’s engine would reside.

Frunks aren’t entirely new. Porsche’s 911 has had front trunks for decades, thanks to its rear-engine layout. But in the EV era, the frunk has seen a renaissance—thanks to the freedom offered by skateboard-style platforms and the absence of bulky engines.

EVs like Teslas and Rivians have made the frunk a widely recognized term, even promoting it as a unique advantage over gasoline vehicles.

Why Do EVs Have Frunks?

Here’s the engineering breakdown:

1. No Internal Combustion Engine

The biggest reason EVs can offer frunks is the absence of a traditional engine. Electric motors are much smaller and can be placed near the axles, often under the floor or rear. This leaves a large vacant space in the front.

2. Flat “Skateboard” Chassis

Most modern EVs use a skateboard chassis, which means the battery is embedded in a flat pack under the floor. This not only lowers the center of gravity but also frees up interior and front space.

3. Improved Weight Distribution

Storing luggage in the front helps evenly distribute weight, which improves vehicle dynamics, especially in sporty EVs.

4. Increased Cargo Volume

Since many EVs don’t have a traditional driveshaft or transmission tunnel, automakers can optimize cargo storage in ways not possible with ICE vehicles.

5. Marketing Differentiation

Let’s be honest: automakers love unique features that differentiate their models. A frunk gives them a talking point—and sometimes even a place to host a “frunk party.”

Are All Frunks Useful? Not Really

While the idea of a frunk is universally appreciated among EV enthusiasts, not all frunks are created equal. In some EVs, the frunk is barely large enough to store a charging cable, while in others, it’s large enough to hold a full week’s groceries or even a couple of suitcases.

Here’s why frunk practicality varies so much:

● Packaging Constraints

Some EVs are built on ICE-converted platforms, where components like HVAC systems and steering hardware still occupy the front bay.

● Component Layout

Some automakers prioritize other components—like large front inverters, cooling systems, or air suspension hardware—over frunk space.

● Cost-Cutting Measures

A usable frunk requires a sealed and waterproof compartment, proper insulation, and accessibility—all of which cost more money to design and manufacture.

So which manufacturers have truly committed to making the frunk more than a gimmick?

Top EVs with the Most Practical and Spacious Frunks (2025 Edition)

Let’s now break down some of the most useful frunks available in EVs today, based on cubic feet, shape, accessibility, and multi-use potential.

1. Rivian R1T & R1S

• Frunk Volume: ~11.1 cubic feet
• Accessibility: Power open/close, flat loading floor
• Why It Stands Out: Rivian offers the largest frunk in any production EV. It’s not only deep and wide, but it’s powered, drainable, and comes with customizable dividers. The R1T also features gear tunnels and additional hidden storage, but the frunk remains its signature cargo advantage.

Use case: Ideal for camping gear, groceries, and even ice and drinks—thanks to its drain plug.

2. Ford F-150 Lightning

• Frunk Volume: ~14.1 cubic feet
• Accessibility: Power liftgate, built-in lighting, USB-C outlets
• Why It Stands Out: Technically the largest front trunk by volume, Ford brands it the “Mega Power Frunk.” It includes power outlets (2.4 kW), lighting, and a modular divider system—making it not just storage but a portable workbench.

Use case: Carry tools, groceries, or even power tools for a remote job site.

3. Tesla Model Y

• Frunk Volume: ~4.1 cubic feet
• Accessibility: Manual open, gas struts
• Why It Stands Out: Compact yet useful. Fits a carry-on bag, backpack, or charger bag. The frunk is well-shaped and has good weather sealing.

Use case: For everyday items—laptops, chargers, small luggage—Model Y’s frunk is functional without being huge.

4. Tesla Cybertruck

• Frunk Volume: ~7 cubic feet (estimated)
• Accessibility: Full-width clamshell open
• Why It Stands Out: Though not as deep as Rivian or Ford, it’s wide enough to store long items, including tools and adventure gear.

Use case: Larger equipment like tripods, flat boxes, or camping items.

5. Porsche Taycan

• Frunk Volume: ~2.8 cubic feet
• Accessibility: Narrow but deep
• Why It Stands Out: It’s small but well-sealed. Porsche reserves most of the cargo space for the rear trunk. The frunk fits one carry-on bag or a briefcase.

Use case: Great for a minimalist setup or carrying your office gear.

6. Hyundai IONIQ 5 / Kia EV6

• Frunk Volume: ~0.7 to 1.9 cubic feet (varies by AWD/RWD)
• Accessibility: Basic, small opening
• Why It Disappoints: On AWD models, the frunk is almost useless. It’s more of a compartment cover than a usable cargo area.

Use case: Maybe store the charging cable and gloves—barely.

7. Lucid Air

• Frunk Volume: ~10 cubic feet
• Accessibility: Split-level design
• Why It Stands Out: Second only to Rivian and Ford in terms of overall frunk utility. It has a multi-layer storage solution and opens wide. Premium insulation and finishes.

Use case: High-end luggage, camera equipment, or luxury gear.

Frunks as a Security Feature

Interestingly, frunks offer more than just space—they offer discretion. Most frunks are invisible to outsiders since there are no rear windows to peek into. If you’re storing valuables, a frunk can be a safer place than a rear cargo area or even a glove compartment.

How Consumers Use Frunks in Real Life?

Based on EV owner surveys and user forums, here are some popular real-world uses:

• Emergency kits: First-aid, jumper cables (yes, for 12V), and air pumps.
• Food delivery: Some drivers use frunks to store food away from passengers.
• Tech gear: Drones, camera equipment, and laptops.
• Travel storage: Luggage overflow, wet clothes (drain plug models), or pet items.
• Ice bins: Several Rivian and Ford owners use the frunk as a cooler.

The Future of the Frunk: Trends to Watch

● Modular Frunk Systems

Upcoming EVs may offer adjustable frunk sizes or removable dividers, making them even more flexible.

● Climate-Controlled Frunks

Some patents show ideas for temperature-controlled frunks to keep food cold or electronics safe.

● Automated Lifting

As frunks grow in size, powered open/close systems are becoming standard for convenience and safety.

● Voice-Controlled Access

With AI and smart assistants being integrated into cars, future frunks could be voice-activated—open your frunk with just a command.

Frunk vs Trunk – Which One Matters More?

While the rear trunk (boot) still offers the bulk of EV cargo space, the frunk provides flexibility. Think of it as bonus storage that makes an EV more practical for:

• Splitting clean/dirty items
• Keeping essentials within quick reach
• Secure storage out of sight
• Situational use (tools, tech, food, etc.)

In many real-world use cases, the frunk can complement or even surpass the traditional trunk in importance—especially for urban drivers or outdoor enthusiasts.

Are Frunks Worth It? A Final Word

Yes—but with caveats.

A well-designed frunk adds genuine daily utility to an EV, improving its cargo-carrying ability, security, and versatility. However, not all EVs make the most of the opportunity. Some are simply space-limited or treat the frunk as an afterthought.

As EV platforms continue to evolve—especially purpose-built ones—expect frunks to become larger, smarter, and more usable in the coming years.
