From the fantasies of 20,000 Leagues Under the Sea to today’s ultra-sophisticated watercraft, humans have always dreamed of conquering land and sea. Amphibious vehicles—the machines that seamlessly transition between these two elements—are the love children of human ingenuity and aquatic envy. Whether used for military operations, scientific exploration, or to impress neighbors, these versatile wonders are engineering marvels. Let’s dive into (pun intended) 11 of the most fascinating vehicles that can travel underwater.
Gibbs Aquada
The Gibbs Aquada is not just an amphibious vehicle. It’s a sports car that transforms into a watercraft. Capable of hitting speeds up to 100 mph on land and 30 mph in water, this vehicle takes versatility to a new level. The Aquada’s wheels retract into the body, allowing its sleek hull to glide over water, turning your commute into a river-bound adventure. And yes, you can drive this thing right off a boat ramp like it’s nothing.
Sealegs
The Sealegs is an inflatable boat equipped with retractable wheels that can transform from a beach vehicle into a full-fledged watercraft in less time than it takes to inflate a pool float. Primarily used for rescue and recreational missions, Sealegs can reach 40 knots on water and up to 10 km/h on land. So, whether you’re ferrying people to safety or avoiding beach parking fees, the Sealegs has covered you.
Rinspeed sQuba
Remember that underwater Lotus Esprit from The Spy Who Loved Me? The Rinspeed sQuba is that, but real. Swiss engineering firm Rinspeed created the sQuba as the world’s first actual submersible car. It can dive up to 10 meters underwater, with scuba tanks providing oxygen to the driver and passengers. Don’t expect it to zoom like a speedboat; the sQuba is more about grace than speed, crawling at about 2 knots underwater and 75 mph on land.
Gibbs Humdinga
Looking more like a futuristic military vehicle than a Sunday cruiser, the Gibbs Humdinga takes rugged to new heights—or depths, depending on your point of view. This amphibious truck can quickly conquer dirt, sand, and snow as quickly as it handles rivers, lakes, and shallow seas. It reaches up to 80 mph speeds on land, but once in the water, it can cruise at 30 knots. Its 300-horsepower engine means it’s not just for show; it can haul seven passengers through almost any terrain or aquatic obstacle in its way. Perfect for the next… off-shore adventure.
WaterCar Panther
If you’ve ever looked at a Jeep Wrangler and thought, “This is great, but I wish it could also cross the Atlantic,” the WaterCar Panther is your dream come true. Designed as an amphibious SUV, the Panther doesn’t just float; it glides. Its secret weapon? A 3.7-liter Honda V6 engine that powers both the wheels and the jet propulsion system. The Panther’s lightweight fiberglass hull helps it transition from road to water with impressive ease, and it can go from land to floating in just 15 seconds.
U.S. Military’s Amphibious Combat Vehicle (ACV)
The Amphibious Combat Vehicle (ACV) is the U.S. Marine Corps’ latest tool for storming beaches and tackling coastal combat missions. This armored beast can carry a squad of 13 fully-equipped Marines and hit 105 km/h (65 mph) speeds on land. Once in the water, the ACV can propel itself through rough seas at a respectable speed of 10 km/h (6 mph), keeping the troops dry and safe. The ACV is part of a new generation of military vehicles that can handle harsh environments, from deserts to oceans. Its thick armor protects it from small arms fire, while its hybrid propulsion system allows it to transition from land to water seamlessly. The ACV’s launch was delayed multiple times as the military tested it under extreme conditions, including simulated sea storms and beach landings.
Gibbs Quadski
The Gibbs Quadski is a hybrid vehicle that zips through forests and lakes. With a top speed of 45 mph on both land and water, the Quadski doesn’t sacrifice performance in either environment. Its rapid transition system allows the wheels to retract once it hits the water, turning it into a high-speed jet ski. Also, the Quadski uses a 140-horsepower engine, making it one of the fastest amphibious vehicles in its class. A hit with adventurers and thrill-seekers, the Quadski is like a superhero in the world of off-road vehicles—land one minute, watercraft the next.
Terra Wind
Ever dream of taking a road trip across the country, then realizing halfway through you’d rather be on a boat? The Terra Wind solves that dilemma by combining a luxury RV with a functional yacht. Fully decked out with marble countertops, a hot tub, and a fully equipped kitchen, this behemoth is essentially a floating mansion on wheels. It may not be the fastest amphibious vehicle out there, but who’s in a rush when you’ve got a hot tub on board? Capable of hitting 80 mph on land and cruising comfortably at 7 knots in water, the Terra Wind is perfect for those who want to camp out anywhere—whether on solid ground or open water.
Sleipnir
Designed for extreme conditions, the Sleipnir is an amphibious vehicle made to navigate the harsh, icy waters of the Arctic. This Norwegian creation was built with survival in mind, featuring reinforced hulls and an advanced heating system to withstand subzero temperatures. While it doesn’t break any speed records, it’s invaluable for polar research missions and rescue operations. On land, its caterpillar tracks provide superior traction on snow and ice, while in water, it moves with a glacier’s slow, deliberate grace. If you’re looking to explore the frozen frontiers of the Earth, the Sleipnir is the trusty companion you need.
DARPA’s Hydra
Leave it to DARPA to create an amphibious vehicle that sounds like something from a Godzilla movie. The Hydra project aims to develop submersible drones that operate above and below water, with military applications like reconnaissance, supply delivery, and combat. While it’s still in development and shrouded in mystery (because, of course, it’s DARPA), we know that the Hydra will be able to transform from a surface craft into a submersible unit capable of deploying smaller drones for various tasks. If there’s ever an underwater robot uprising, you can bet the Hydra will lead the charge.
Nereus
While most vehicles on this list are for fun or tactical use, the Nereus is all about scientific discovery. Created by the Woods Hole Oceanographic Institution, this deep-sea submersible can dive to 36,000 feet, far more profound than most human-made vehicles have ever ventured. Nereus was designed to explore the deepest parts of the ocean, such as the Mariana Trench, where no amphibious car or speedboat dares to go. While it’s less flashy than a convertible that can swim, Nereus has contributed more to our understanding of the ocean than most of us ever will. So, while it may not make for a great getaway car, it’s the most educational ride on the list.
