For more than a century, every car has followed the same basic idea: You sit behind a steering wheel. You look through it. And directly behind it lives a cluster of gauges. Speed. Range. RPM. Warnings. Information. That rectangle whether mechanical needles or digital screens became one of the most recognizable objects in automotive design. Subscribe Enjoying my DIY car content?

BMW is now asking a radical question: What if the instrument cluster simply disappeared? With the arrival of the Neue Klasse generation, BMW is replacing the traditional driver display with something that feels closer to science fiction than automotive evolution: a panoramic projection stretching across the base of the windshield, turning the glass itself into the primary interface...

Rivian’s Gear Tunnel: The Hidden Cargo Idea That Might Change Truck Design

For decades, pickup trucks evolved in mostly predictable ways: bigger beds, larger cabs, more storage bins, more cupholders, and occasionally a clever tailgate trick. Then an electric startup quietly introduced something that made people stop and say: Wait… why didn’t anyone do this before?
That idea is the Gear Tunnel.
Not a front trunk. Not a storage drawer. Not a secret compartment hidden under the floor.
A full-width cargo tunnel running through the truck, mounted directly behind the passenger cabin.
When Rivian launched the R1T, this unusual feature immediately became one of the most talked-about details of the vehicle and for good reason. It feels obvious once you see it, yet it only became practical because of the way electric vehicles are built.
And that’s what makes it interesting.
The Truck Storage Space Nobody Was Looking At
Traditional pickup trucks have always been constrained by mechanical packaging.
Under the cab: frame rails, driveshafts, exhaust systems, fuel tanks, transfer cases, suspension components.
That entire middle section of the vehicle was crowded.
Designers worked around it.
Storage solutions ended up being external toolboxes mounted in the bed, roof racks, bed drawers, lockboxes, cargo organizers.
But electric trucks changed the rules.
Instead of stacking mechanical systems throughout the chassis, modern EVs often use a skateboard platform: a large battery pack integrated into the floor with compact electric drive units at the axles.
That frees up volume in places vehicle designers historically couldn’t use.
Most EV makers took advantage of this by adding a frunk.
Rivian looked elsewhere.
Instead of asking:
“Where can we put another trunk?”
They asked:
“What if we use the empty space between the cabin and the rear wheels?”
The result became the Gear Tunnel.
What Exactly Is the Gear Tunnel?
Imagine standing beside the truck.
Now imagine opening a large side door just behind the rear passenger door.
Instead of finding a shallow storage pocket, you discover a long enclosed tunnel stretching completely across the vehicle.
Open the opposite side and you can see daylight all the way through.
That’s the Gear Tunnel.
It sits beneath the rear seats and ahead of the truck bed.
It’s wide enough for awkward gear that doesn’t fit naturally in a bed or cabin and protected from weather and theft.
Unlike a pickup bed, your equipment stays enclosed.
Unlike a cabin, muddy or bulky equipment doesn’t need to ride with passengers.
And unlike a roof box, loading heavy gear doesn’t require climbing.
Simple concept.
Huge impact.
Why Owners Actually Love It
Interesting automotive ideas often look good in press photos and then disappear in real life.
The Gear Tunnel did the opposite.
Owners started inventing uses that Rivian probably never fully predicted.
Ski and Snow Gear
Long, narrow items finally have a natural home.
Skis, poles, boots, avalanche gear everything slides into an enclosed compartment instead of occupying cabin space.
No roof rack required.
Recovery Equipment Without the Mess
Off-road drivers discovered the tunnel is perfect for dirty equipment.
Tow straps.
Recovery boards.
Shackles.
Air compressors.
Mud-covered gear stays separated from passengers.
Camera and Production Equipment
Photographers and videographers found another use.
Tripods.
Lighting stands.
Protective cases.
Long camera rigs.
Expensive equipment stays hidden and weather protected while remaining easy to access.
The Camping Setup That Made Everyone Pay Attention
Then came the camping crowd.
People began building compact field kitchens inside the tunnel.
Slide-out cooking platforms.
Storage modules.
Coffee stations.
Prep surfaces.
The tunnel became a miniature camp galley.
Instead of unpacking bins every stop, users simply open the side and start cooking.
That’s when people realized this wasn’t just storage.
It was infrastructure.
The Door That Becomes a Seat
One of the cleverest details isn’t even inside the tunnel.
The side door itself can support weight and act as a small seat or platform.
Open the tunnel.
Sit down.
Change boots.
Take a break on the trail.
Use it while preparing camp meals.
It turns a storage compartment into usable outdoor furniture.
That tiny detail captures the entire philosophy behind the truck: making space do more than one job.
Why This Idea Exists Because of EVs
The Gear Tunnel isn’t just clever industrial design.
It’s a preview of what happens when vehicles stop being arranged around combustion engines.
Electric platforms remove old constraints.
That means designers can rethink questions that seemed solved decades ago.
Where should storage go?
Where should people sit?
What spaces inside a vehicle have always been wasted?
The Gear Tunnel suggests the next generation of vehicles may become less about adding features and more about reclaiming forgotten volume.
Historically, trucks gained capability by getting physically larger.
The Gear Tunnel gains capability by using space more intelligently.
That’s a fundamentally different direction.
Will Everyone Copy It?
Not necessarily.
The Gear Tunnel works particularly well because of Rivian’s proportions and architecture.
But the broader idea finding useful volume inside EV platforms is almost certainly here to stay.
Expect more hidden compartments.
More dual-purpose spaces.
More integrated storage.
More designs that feel impossible in traditional vehicles.
The most interesting EV innovations may not be acceleration numbers or giant screens.
They may be quiet packaging ideas that suddenly make old designs feel outdated.
And the Gear Tunnel is one of the best examples yet.
Because once you see a pass-through storage tunnel hidden inside a truck, it becomes surprisingly difficult to imagine why trucks weren’t built this way all along.
Walk into a dealership in late 2026 and the experience may feel strangely unfamiliar. The usual assumptions no longer apply. Family cars are becoming electric by default. Luxury cars are becoming rolling software platforms. Performance models are adding batteries instead of losing excitement. And entirely new brands many of which most British drivers had never heard of five years ago are arriving with serious ambitions. This isn’t a concept-car future anymore.
