# The Porsche Frunk: A Complete Guide for 911, Cayman & Boxster Owners
*By The Frunk Club | thefrunkclub.com*

Let’s get something straight from the beginning. You spent somewhere north of $80,000 on a car with the engine in the wrong place. Not wrong by accident — wrong by genius. Porsche has been putting their engines in the back since 1963, and somewhere along the way they realized that all that empty space up front needed a job. The result is one of the most beloved and secretly practical features in all of sports car ownership: the frunk.
The front trunk. The forward hold. The anti-trunk. Whatever you call it, if you own a Porsche 911, Cayman, or Boxster, you have one — and if you’re not using it well, you’re leaving the best part of your car on the table.
This is your complete guide.

## What Is a Frunk, and Why Does Your Porsche Have One?
A frunk — front trunk — exists because your Porsche’s engine doesn’t. At least not up front. The 911’s iconic flat-six sits behind the rear axle, which is either the greatest engineering decision or the most stubborn automotive tradition in history, depending on who you ask. The 718 Cayman and Boxster take a slightly more sensible approach with a mid-engine layout, their flat-four or flat-six sitting behind the cabin but ahead of the rear axle.
Either way, the front of the car is liberated from containing anything combustion-related. Porsche fills that space with a luggage compartment — lined, latched, and often more useful than it has any right to be.
This is the frunk. And it has been part of the 911 since the very first car left Stuttgart in 1963.

## Frunk Capacity by Porsche Model
Not all Porsche frunks are created equal. Here’s what you’re actually working with across the current lineup:
**Porsche 911 (992 generation, 2020–present)**
The 992’s frunk measures approximately **4.6 cubic feet (130 liters)**. In practical terms: two carry-on suitcases, a track day helmet and jacket, a week’s worth of groceries, or one very disappointed golden retriever. The frunk runs roughly 28 inches wide, 16 inches front-to-back, and up to 23 inches deep at the back (it slopes, so use the 17-inch front measurement as your benchmark for rigid luggage). Despite the 992 being wider than previous generations, the frunk is actually slightly smaller front-to-back than the 991 — Porsche prioritized aerodynamics at the front. Pack accordingly.
**Porsche 718 Cayman (current generation)**
Because the 718 is mid-engined, it enjoys two separate storage compartments: a **5.2 cubic foot (147L) frunk** under the front hood, plus a **9.7 cubic foot rear trunk** behind the engine. Combined, you’re looking at nearly 15 cubic feet — genuinely impressive for a two-seat sports car. The frunk is deep and wide. Two carry-on rollers fit with room to spare.
**Porsche 718 Boxster (current generation)**
Same frunk as the Cayman at **5.2 cubic feet (147L)**, but the rear is smaller at **4.4 cubic feet** because the convertible roof mechanism lives back there. Plan your road trips with soft-sided bags for the rear and rigid luggage up front.
**Porsche Taycan**
The electric Taycan flips the script entirely — the frunk shrinks to around **2.8 cubic feet (81L)**, sacrificing storage for its massive battery and front motor. More symbolic than practical, but it still swallows a laptop bag, gym gear, or the charger cable you definitely need to stop forgetting.

## What Do Porsche Owners Actually Keep in Their Frunks?
We asked around — Rennlist forums, PCA club members, Instagram, the parking lot at Laguna Seca. Here’s what real Porsche owners actually store in their frunks:
**The Track Day Setup**
The 911 frunk was practically designed for track days. A soft helmet bag fits perfectly, leaving room for driving gloves, ear plugs, a radio, and sunscreen. Many owners keep a dedicated “track kit” in a frunk-shaped duffel that stays packed all season.
**The Daily Driver Essentials**
Emergency jumper cables (compact lithium pack), a microfiber cloth, a bottle of Porsche-correct touch-up paint, and a car cover for those days you park in the city and walk away nervous. Practical? Yes. Glamorous? Absolutely.
**The Road Trip Configuration**
A 22-inch carry-on roller on its side, a soft overnight bag stuffed into the gaps, and somehow still room for a Hydro Flask and a copy of the latest issue of Christophorus. The 911’s frunk is genuinely capable for weekend trips if you think soft-sided luggage first.
**The Car Show Essentials**
Detail spray, a clay bar kit, a set of microfiber towels, and those little cone display placards that explain to curious strangers what year your Carrera is. PCA Concours competitors sometimes fit an entire detailing kit up there without touching the rear seats.
**The Grocery Run**
Yes. Multiple Porsche owners have confirmed: you can do a full grocery run in a 911. The frunk swallows six full grocery bags comfortably. This is perhaps the most Porsche thing you can do — pick up milk and eggs in a vehicle that costs more than some houses.

## Frunk Tips: How to Use It Like a Pro
**Tip 1: Go soft-sided whenever possible.**
The frunk’s irregular shape (deeper at the rear, narrower at the bottom) makes rigid hard-shell luggage a puzzle. Soft duffels and roll-top bags conform to the space and let you pack 20% more than you think.
**Tip 2: Keep a frunk liner.**
The factory carpet is fine, but a custom TPE liner protects against the inevitable spilled coffee, muddy boots from a car show, or tracking fluid from a track day. Suncoast and Rennline both make excellent model-specific options.
**Tip 3: Use the frunk anchor points.**
Every 911 and 718 frunk has a hook or anchor point (usually that small loop near the back edge) for securing bags. Use it. A rolling suitcase in the frunk will become a battering ram if you take your first corner at speed.
**Tip 4: The 90-liter fuel tank changes nothing.**
Porsche 911 owners often ask whether specifying the optional 90-liter fuel tank affects frunk space. It does not. The additional fuel capacity is housed in a separate chamber beneath the frunk floor with no impact on the storage volume above.
**Tip 5: Know the lid’s opening angle.**
The 911’s front hood opens all the way and holds itself up hydraulically — it’s a full, dignified opening. The 718’s frunk lid opens more shallowly. Tall bags loaded upright may catch the hood edge. Tilt them slightly forward before lowering the lid.

## The Frunk Across Generations: A Brief History
The frunk has grown with every 911 generation, roughly tracking the car’s overall size:
- **Air-cooled 911s (1963–1998):** Tiny but charming. Early 911s had modest front storage — enough for a briefcase or small weekend bag. Part of the reason vintage 911 road trips required serious packing discipline.
- **996 and 997 (1997–2012):** Meaningful growth in frunk volume. The 997 brought the capacity closer to what modern owners expect, and the shape became more usable.
- **991 (2012–2019):** The first 911 where the frunk felt genuinely practical for everyday use. Two carry-ons became the standard test.
- **992 (2020–present):** The largest, most refined frunk in 911 history. Slightly shorter front-to-back than the 991 but wider and better shaped. The interior lining is excellent, and the hydraulic struts are a proper upgrade from the prop rod of earlier cars.
Each generation got better. The 992 is currently the gold standard of frunk engineering — which feels like a very specific superlative, but we stand by it.

## Porsche vs. The Competition: Who Has the Best Frunk?
This is where it gets fun. Porsche isn’t the only brand building cars with their engines elsewhere. Ferrari, Lamborghini, and McLaren all offer frunks — but not equally.
The Lamborghini Huracán’s frunk is a legitimate **150 liters**, which is actually larger than the 911’s. Lamborghini owners on the forums describe fitting a single 50-liter soft bag and a small toiletry kit. Tight, but usable.
The Ferrari 296 GTB’s frunk is a notably generous **201 liters** — a deliberate move by Ferrari to make their newer hybrid cars more livable. The F8 Tributo it replaces offered 200 liters. Ferrari has been quietly winning the exotic frunk wars for a decade.
McLaren’s Artura frunk is **150 liters (5.3 cubic feet)** — usable, but the shape is awkward and the opening angle is shallow.
The Porsche 718 Cayman still wins on total combined storage, simply because it has two trunks. The 911 wins on elegance — that deep, well-lined frunk that opens wide and holds its lid like it means it.

## The Frunk as Identity
Here’s the thing nobody tells you before you buy a Porsche: the frunk becomes part of your personality. You’ll find yourself explaining it at every car show. You’ll catch yourself sizing up your frunk versus someone else’s. You’ll have opinions — strong ones — about frunk liners and organizers and the correct way to pack a 911 for a weekend in the mountains.
This is not an accident. The frunk is the perfect metaphor for what Porsche ownership actually is: a car that does things backwards from everyone else, in a way that somehow works better than if they’d done it the normal way.
The engine’s in the back. The trunk’s in the front. And somehow, inexplicably, it’s perfect.
