There are a few amphibious vehicles out there, allowing drivers to have fun on both dry land and sea. WaterCar's newest addition called Panther is essentially a Jeep that can handle both opposing terrains. The outer body resembles a Jeep CJ-8. An Acura 3.7-liter V6 is located in the back of the vehicle to provide over 300 horsepower. With a jet boat drive, retracting wheels and a fiberglass hull, the Panther is nothing short of awesome. It is capable of reaching speeds over 80 miles per hour on the road but most notably it can hit about 45 miles per hour on top of the water.

The interior of the Jeep is a little longer than the standard CJ-8, measuring 15 feet long. That allows passengers to have more room which comes in especially handy while enjoying a cruise on the lake. The panther was recently declared the world's fastest amphibious car. While transitioning from land to water, the Panther can enter the liquid terrain at speeds up to 15 miles per hour. How do you like it? Category Amphicar, the Fastest Car on Water, the Fastest Boat on Land - autoevolution autoevolution Amphicar, the Fastest Car on Water, the Fastest Boat on Land / Home / News / Coverstory We are not sure how many of you out there reading this know that, sometime in the history of the automobile, a strange hybrid vehicle crawled its way into the public eye, bringing with it a concept so simple no one really thought about it before. It was called the Amphicar and, as the name suggests, it was an amphibious vehicle that could easily travel over land and through water.

Considered by many the single mass produced non-military amphibious vehicle ever made and by few one of the ugliest vehicles of all times, the Amphicar came and went without creating the big waves it hoped for in the automotive puddle. Of course, the whole thing had to start somewhere and, as you will see while reading this, it is not over yet. But let's take one step at a time. THE IDEA: Orukter Amphibolus The crazy idea of combining a road vehicle with a water-going one is about as old as the automobile itself. The first amphibious vehicle to hit both land and water allegedly surfaced in the early 1800s, when American Oliver Evans created a steam-powered contraption which managed to get driven well over a mile on the streets of Philadelphia and sailed on the Delaware River. The contraption was called Orukter Amphibolus and became the first amphibious steam carriage ever built. It was later put to use as a dock-cleaning dredge.

Nothing else notable happened on the civilian amphibious front until sometimes in mid 1910s, when William Mazzei came up with what he called the Hydromotor (or Hydrometer): a mid-sized car, propelled by a Continental engine and said to be capable of reaching 60 mph on land and 25 mph on water. Mazzei's idea was picked up by George Monnot, who took it one step closer and created the Hydrocar, a combination between a boat, a car and a truck. This happened in the eve of the first World War and, once the war began, all the advancements achieved until then got swallowed by the war effort for military use. THE FIRST: Schwimmwagen The man credited with creating the first amphibious mass production vehicle is not an American, but German Ferdinand Porsche. During the war, Porsche created the so called Kubelwagen, the German equivalent of the American Jeep. Forced by the rigors of war, the bucket car, as the Kubelwagen was known, needed to be converted and made capable of traveling through water as well.

Porsche converted it and the Schwimmwagen (swimming car) was born, considered by many the first mass produced amphibious vehicle in existence (albeit, for military use). Porsche had his lead designer, Erwin Komenda, create an until-then-never-built body made of a unique bodytube structure for the amphibian. He then took the parts (including engine) from the Volkswagen Type 86 four-wheel drive prototype of the Kubelwagen and combined them into giving birth to the Schwimmwagen. In the end, the amphibian was a 4WD vehicle, equipped with ZF self-locking differentials on both front and rear axles. To make the transition from land to water, the 4x4 dropped a screw propeller into the water, from the rear deck engine cover. Drive was ensured via a coupling directly to the engine's crankshaft. When in water, the front wheels became rudders, making the car as easy to drive in the water as it was on land. THE REAL DEAL : Amphicar The idea to create an amphibious vehicle for private use spawned in the mind of German national Hans Trippel sometimes after the end of the Second World War.

Having been involved in the German war effort, Tripple got his hands on a Bugatti factory in France after the invasion and began building amphibious vehicles for the Wehrmacht. When the war ended, Tripple took his vehicle manufacturing expertise and turned his sights on building small displacement vehicles. The business was not as successful as he would have wanted, so he had to rethink his entire strategy. Taking advantage of his expertise with amphibious vehicles, Tripple began contemplating the idea of creating a car which could be sold to civilians, especially those, of course, in the US. Tripple partnered with the Quandt Group to start the manufacturing of what he called the Amphicar, whose prototype was ready in 1959 and presented at the Geneva Salon the same year. Production of the vehicle began in 1961, with its creator expecting to sell around 20,000 units per year. Amphicar came in the form of a two-door four-seat convertible, equipped with a folding cloth top.

Dubbed model 770 due to the fact that it could achieve 7 knots on water and 70 mph (110 km/h) on land, the car was powered by a 1.2l four cylinder overhead-valve engine sourced from Triumph. To suit its water-going abilities, the engine was placed at the back, from where it could easily power the two nylon propellers fitted underneath the car. The engine produced 43 hp at 4,750 rpm. As was the case with the Schwimmwagen, the Amphicar used its front wheels as rudders. They steered a body made up of a box-section steel sub-frame (parallel longitudinal members and five cross-members). Looked at from underneath, the body of the car looks like the hull of a boat. To make it suitable for the two environments in which it is supposed to operate, the Amphicar employed land-and-water transmission built by Hermes, which allowed for the independent or simultaneous operation of the two propellers. For land, it had 4 gears plus reverse, while for water use it only had 2 gears.

As revolutionary as it seems (and you must admit, the concept is simply brilliant: imagine going to the sea side and not having to rent a boat for your off shore adventures), the idea never caught on. The 20,000 units sold per year envisioned by Tripple turned to dust as soon as Amphicar hit the water/road. The main reason behind this is the fact that the contraption was not as cheap as to encourage sales. Back in its glory days, it retailed for anywhere in between $2,800 and $3,300. Another factor which led to its demise was the fact that the new EPA and DOT regulations came into effect in 1968, regulations which Amphicar could not meet. As the US represented about 90 percent of its global business, the company, Amphicar Corporation, was sent into disarray. In all, the car stayed in production from 1961 to 1968, a period during which 3,878 units were built. When it went under, the remaining inventory of unused parts were purchased by Hugh Gordon, whose Gordon Imports is now the main source for Amphicar parts.

Even with its untimely demise, Amphicar will remain in history as the single car which managed to cross the English Channel, without being loaded on any boat. THE FUTURE : Aquada Unsuccessful as it was, the idea of a water-going car/road going boat didn't die out. Someone is at it again, this time with all the arsenal provided by the modern world. Gibbs Technologies, a Michigan based manufacturer, is currently working on several High Speed Amphibious technologies (HSA) to be used in such vehicles. What they came up with so far, in terms of civilian use, is the Aquada, the result of a seven-year long research and development program. Unlike the Amphicar, the Aquada uses a jet propulsion system which, according to Gibbs, produces around 1 ton of thrust. The Aquada uses a 175 hp V6 engine paired with a five speed automated transmission with reverse, as well as power assisted steering on both water and land. All the details you need about Aquada can be found in the PDF attached below.

California-based WaterCar has designed the world's fastest Jeep-style vehicle that can be driven straight from the land into the water and goes from a car to a boat in just 15 seconds.

Called the Panther, the vehicle can reach water speeds of up to 45mph - almost as fast as an average speedboat - and is fitted with a custom-made 3.7 litre V6 engine, fibreglass hull and lightweight chromoly steel chassis.

The wheels are lifted into the chassis using hydraulics and the car switches to a boat using a 'jet drive' lever THE PANTHER'S SPECIFICATIONS Share this article Share WaterCar partner Fred Selby, 66, from Newport Beach, California spent 11 years fine-turning the machine before he felt ready to put it on the market.

The Panther's design is based on a Jeep CJ8 Scrambler, however, because the chassis of the Jeep was too heavy for the water, the Panther's lightweight chassis is made of chromoly steel. Once in the water, the Panther is remarkably stable for a boat that is only 15 ft (4.6 m) in length. The Panther's chromoly steel chassis was designed to slip into a fibreglass hull. The hull is also filled with closed-cell styrofoam to help the car stay afloat. The engine for the Panther is the latest-generation Acura 3.7-liter VTEC V-6 engine, custom-fitted with aluminium parts, a overhead camshaft cylinder head and 24 valves The Panther was designed by WaterCar partner Fred Selby, from California.

Both intake and exhaust valves are controlled by Acura's Variable valve Timing and lift Electronic Control (VTEC) system. This engine produces 305 horsepower at 6,300 rpm and on land the Panther can reach speeds of around 80mph. The Panther weighs 2950lbs and is 15ft long. As a boat, the amphibious vehicle is powered by a Panther marine propulsion jet. It needs to be travelling at around 15mph to get enough momentum to enter the water WaterCar's Panther car can carry up to four passengers in both land and water mode. The vehicle can be fitted with fishing rod holders, pictured. It can be sailed in both salt and fresh water and the chassis is protected from water damage It needs to be travelling at around 15mph to enter the water and can then reach top speeds of almost 45mph.

To drive the Panther in water, the driver must put the four-speed gear changer in neutral, pull a knob to switch the transfer case to 'jet drive', hydraulically lift the wheels and tyres out of the water, and start boating. This entire process takes less than 15 seconds. The Panther starts at £49,800 ($76,000) for a 'Rolling chassis', £70,000 ($106,000) for a 'Turn-key minus' version, and £89,000 ($135,000) for a complete Panther. The Rolling chassis is a kit and additional components can be bought off the shelf. The Turn-key minus version doesn't come with an engine.

'Revolutionary in its design and engineering, a WaterCar Panther takes you anywhere you want to go. 'The thrilling acceleration is provided by a Honda V6 V-Tec motor. 'You can leave the highway behind thanks to its long travel off road suspension and travel in the water courtesy of the panther jet. 'And do all this with the security of knowing you are surrounded by a state of the art revolutionary designed composite body. James Bond, played by Sir Roger Moore, famously drove an amphibious Lotus Esprit, pictured, from the land into the sea during the 1976 film The Spy Who Loved Me 'Nothing compares to driving a Panther.' The design looks like a four-wheel drive and the bodywork is made from a fibreglass chassis that is capable of withstanding salt-water.

The outboard motor which powers the car is capable of travelling 2000,000 miles before needing serious maintenance. 'You will be absolutely blown away by the Panther,' said Selby. 'Our WaterCar team did a fabulous job of creating an extraordinary vehicle that is exciting, raw fun, yet incredibly practical.' What Is a Car Boat? | eHow What Is a Car Boat? Cars on the quay image by a4stockphotos from Fotolia.com A car boat is hybrid vehicle, meaning it's built to operate as both a car and a boat. This type of vehicle is also called an amphibious vehicle. This name is derived from the term amphibian; like a frog or a newt, a car boat operates on land and water. But unlike other larger amphibious vehicles, a car boat looks like what it sounds like. On land, a car boat looks and runs like a car. In the water, a car boat still looks like a car, but it floats and can be propelled. To create a car boat, you need to add wheels to a boat, or create a car that floats. Car boats range from homemade versions built by hobbyists to specially manufactured high-end models.

Structure Most importantly, car boats are waterproof. A car boat requires welded seams or waterproof marine sealant on the seams to prevent leakage. The bottom of a car boat is shaped like a hull. A car boat's volume must be bigger than its displacement in order to float. With a homemade version of a car boat, the engine is usually an outboard motor mounted on the rear of the car boat with a propeller under the water. Manufactured models often have an inboard motor. History People have been considering the idea of a car boat since the 1900s, but the concept of an amphibious car was really developed and used by the Germans in WWII, with the advent of the Schwimmwagen. According to the December 1944 issue of the "Intelligence Bulletin," a publication of the Military Intelligence Service throughout WWII, the Schwimmwagen resembles a small sports car with a boat-shaped body. The Schwimmwagen holds the record for mass production of an amphibious vehicle. Modernity The Gibbs Aquada is a duck-shaped convertible, according to Popular Mechanics. The Aquada can travel up to 100 mph on the highway and 30 mph in the water.

The wheels retract in 13 seconds and the vehicle switches from V6 to water jet propulsion. In 2010, the Gibbs Aquada sells for about $150,000. Records In 2004, Sir Richard Branson set a new record for the fastest crossing of the English Channel by an amphibious vehicle, driving a Gibbs Aquada. Branson crossed the channel in one hour and 40 minutes, stating that the Gibbs Aquada "is a great beast. It drives fantastically well on land and then it turns into the most remarkable boat on water." The previous record was six hours. Popular Culture A car boat appeared in the 1977 James Bond movie "The Spy Who Loved Me." Bond's water ride was a Lotus Esprit that converted into a submarine.

Word History Amphibians are not quite fish and not quite reptiles.

Like fish, they spend part of their lives living in water and breathing with gills; like reptiles, they usually spend another part of their lives breathing air with lungs and able to live on land. This double life is also at the root of their name, amphibian, which, like many scientific words, comes from Greek. It is made up of the Greek prefix amphi-, meaning "both" or "double," and the Greek word bios, meaning "life." Both these elements are widely used in other scientific words in English: bios, for example, is also seen in words like biology, antibiotic, and symbiotic. reptile , amphibian - A reptile has dry, scaly skin, while an amphibian has moist skin.

Is it a speedboat? No, it's WaterCar's Panther amphibious vehicle Is it a Jeep? Is it a speedboat? No, it's WaterCar's Panther amphibious vehicle View gallery - 40 images Recreational amphibious vehicles are nothing new, but most are one-offs, and most tend to be boats that can creep on land, or cars that slosh slowly through water. There are exceptions, notably entries from Gibbs , but arguably, amphibious vehicles have not made the grade as true all-round vehicles that can be driven to work during the week, and on the lake on weekends. WaterCar's new Panther straddles the divide. Take a Jeep CJ-8, put a Honda Acura 3.7-liter V6 in the back to provide 305 hp, add a fiberglass hull, retracting wheels, and a jet boat drive and you've got the new Panther from WaterCar, which it claims is the world's fastest amphibious car.

Capable of doing over 80 mph (127 km/h) on the road and 44 mph (70 km/h) on the water, the Panther is equipped with a long-travel off-road suspension that allows access to less user-friendly lakes. The appearance of the Panther takes after the Jeep CJ-8 Scrambler , with a stretched wheelbase that provides extra interior room. Because the Jeep chassis proved too heavy, so WaterCar designed a lightweight chassis made of chromoly steel. Having properties (weldability, formability, strength, ductility and toughness) that greatly exceed those of regular carbon steel, the choice of chromoly steel, while pricey, solved the Panther's weight problem. The Panther's chassis was designed to slip neatly into a fiberglass hull, and is secured therein by modern epoxies, thereby reducing noise and shimmy during hard handling. The hull and chassis incorporate advanced composites where extra strength and toughness is required, and the hull is filled with closed-cell styrofoam, rendering the Panther nearly unsinkable. What goes inside the hull and chassis includes a powerful powertrain that provides motive force both on land and water.

The engine for the Panther is the latest-generation Acura 3.7-liter VTEC V-6 engine. An all-aluminum powerplant, the V-6 is equipped with single overhead camshaft cylinder heads and 24 valves. Both intake and exhaust valves are controlled by Acura's Variable valve Timing and lift Electronic Control (VTEC) system. This 3.7-liter engine is a bored and stroked version of the Acura 3.5-liter engine. As this left little clearance between the cylinders, the cast-in iron cylinder liners of the 3.5 liter were replaced by high-silicon aluminum liners. This results in better cooling and tighter piston ring seals. The compact and efficient 3.7-liter engine produces 305 horsepower at 6,300 rpm with special emphasis on mid-range torque giving this VTEC a peak torque of 274 lb-ft (371 Nm) at 4,500 rpm.

The Panther uses WaterCar's own transfer case with Winter's Quick Change gears and components to transfer power between a model 091 VW Vanagon bus four-speed manual transaxle driving the rear wheels, and the H450 Panther Jet drive. WaterCar's transfer case is rated at 1,000 hp, so should have a long service life in the Panther. The H450 Panther Jet drive is rated to 500 hp input. Enough tech specs – how does the Panther perform? On the road the Panther is capable of a maximum speed somewhere north of 80 mph (128 km/h). Acceleration times are not yet available, but with 305 hp (232 kW) driving a car weighing just under 3,000 lb (1,340 kg), it is reasonable to expect snappy, if not extreme, acceleration. The VTEC engine has a compression ratio of 11.1:1, and requires 91-octane premium gasoline to avoid detonation.

Entering the water can be done at speeds up to 15 mph (24 km/h) if there is no step higher than about six inches (15 cm) and the beach is sufficiently firm. Some spectacular entries and exits from the water appear on the video below. Once in the water, the pilot places the four-speed in neutral, pulls a knob to switch the transfer case over to jet drive, pushes a knob to hydraulically lift the wheels and tires out of the water, and start boating. The entire procedure takes less than 15 seconds. Once in the water, the Panther is remarkably stable for a boat that is only 15 ft (4.6 m) in length. It leans a bit in tight turns, but makes the most of the low center of gravity resulting from having both automotive and marine drive systems. This also renders the Panther a bit reluctant to get out of the hole to planing speed, but the amphib appears to handle well at its top speed of nearly 45 mph (72 km/h). Remarkably, the Panther maintains an even keel on the water even when stopped. It appears to be slightly low at the stern, but at most by an inch or two.

The video shows a person diving from the Panther, which again appears to take the sudden shift of weight in stride. The Panther has all the power and speed needed to pull water skiers or wakeboarders, with the vehicles getting up to enough speed to let even most barefoot skiers to get on top of the water. The Panther's design also allows it to function well as an off-road vehicle. This is due in part to the Jeep heritage together with the wide 30X9.50R15 tires, but is mainly the result of WaterCars designing a long-travel suspension system for the Panther. The primary purpose for this suspension was to allow the Panther to drive directly in and out of the water without requiring a slipway, but in the end it also gives the Panther a chance to shine on, for example, Arizona sand dunes. As a rear wheel drive, it is probably best to go off-road only in locations with which you are familiar, or together with a four-wheel drive vehicle that can tow you out of soft spots. Despite that, there are many situations in which off-roading just adds to the Panther's potential for fun.

All in all, early descriptions of WaterCar's Panther suggest that it will provide real enjoyment to anyone living on or near water. The Panther is pricey, starting at US$76,000 for a "Rolling chassis", $106,000 for a "Turn-key minus" version, and $135,000 for a complete Panther. The reason for the uncompleted models is that WaterCar's legal and regulatory requirements are far less if they sell kits instead of completed vehicles. The rolling chassis requires a good bit of work and additional components, but the components can be bought off the shelf. The Turn-key minus version lacks the engine and automobile side of the powertrain. If buying a complete Panther, WaterCar's approach will be to find an outside firm that will complete your amphib for you. Perhaps the fairest price comparison for the Panther is with separate vehicles. A decent off-road capable car that will tow a boat trailer that carries a 45 mph (72 km/h) boat. When you look at it that way, the price seems a bit more in line.

Besides, being able to drive to a lake, drive into the lake, speed past gawking landlubbers, go back to ground for a nice meal, and then slipping into the water to enjoy a slow twilight cruise through the span of London Bridge (now in Lake Havasu, Arizona) before returning to the road home is surely worth a bit of sticker shock.

Subscribe The U.S. Marine Corps is one of the very few fighting forces in the world that can quickly insert major combat units into remote locations without first securing nearby bases. That is what makes the Marines "expeditionary," the adjective the Corps most favors in describing its contribution to national security.

Relying on floating bases called amphibious ready groups -- typically, groups of three warships specially equipped for launching air and surface assaults against land objectives -- the Marines can sustain combat without needing to build up bases ashore or win the favor of local leaders. With over 80% of the world's population living near coastlines, having the ability to execute large-scale amphibious operations on short notice gives the Navy-Marine Corps team unique leverage in an unpredictable world. However, it is becoming increasingly dangerous to conduct "forcible entry" operations from the sea. Many littoral countries now have long-range anti-ship missiles that can target amphibious warships if they do not stay well over the horizon. Marines approaching coastlines may be subject to withering fire from defenders ashore, and once on land they have to deal with threats such as improvised explosive devices and explosively formed penetrators that can slice through armor. The Marine response has been to adapt its technology and tactics to new warfighting realities.

For example, it led the joint force in adopting tilt-rotor technology that combines the speed and range of an airplane with the vertical agility of a helicopter, and now it is investing in a new generation of "connectors" that can quickly transport combat vehicles and troops through water from distant warships to within a few thousand yards of beaches. Introduction of the vertical-takeoff-and-landing version of the F-35 fighter will give Marine aviation the survivability of stealth, the situational awareness of integrated sensors, and the accuracy of precision-guided munitions -- without needing an airstrip on which to land. But there is still one piece missing from this tapestry of warfighting tools: a next-generation amphibious troop carrier that can safely transport infantry from ship to shore. The current amphibious tractor, or "amtrac," on which the Corps relies has been in use for over 40 years, and is very much showing its age. Although it can make reasonable speed in water -- about eight miles per hour -- it is hard to maintain, and once it reaches land it lacks the features needed to cope with a wide array of emerging threats.

What the Marines need is an armored troop carrier that can move farther and faster in water, and then drive quickly across beaches into any enemy's interior, successfully defeating threats to itself and dismounted infantry. BAE's offering in the Amphibious Combat Vehicle competition was designed from its inception to operate both on land and in the water. Note the propeller (one of two) at the back end and the wave-breaking configuration of the front end. It can do 65 miles per hour on land with a full combat load, and 8 miles per hour in the water. (Retrieved from BAE Systems) The Marines had a program for developing a high-water-speed troop carrier with all these attributes. In fact, they had four programs. Each was canceled, because the Corps couldn't live with the tradeoffs required to combine high speed in water with protected mobility on land. As Deputy Commandant Kenneth Glueck explained in an article for the Marine Corps Gazette last year, if you want to move fast in the water, you need to minimize weight -- for example, by taking off armor -- and give the vehicle a flat bottom that will allow it to glide on the surface.

But those features could prove fatal once ashore, because thin armor can't cope with ballistic threats, and flat bottoms can't dissipate the energy from improvised explosive devices. So now the Marines are trying a very different approach to replacing their aged troop carriers in which the objectives of protected mobility on land and increased speed in water are dealt with separately. The program is called Amphibious Combat Vehicle, and it proposes to first field a vehicle that can deliver better performance on land, and then evolve over time to improved performance in water using new technologies. If it still proves too hard to reconcile enhanced land and water performance in a single vehicle, then the service will probably rely on fast-moving sea connectors to get the vehicles from ships to near shore (Glueck points out that once water gets shallow, speed has to slow to that of the legacy vehicle anyway). The new acquisition strategy is a step-by-step, evolutionary approach that the Government Accountability Office says is more in keeping with best practices than the leap-ahead concepts the Marines previously attempted. There would be three increments of the Amphibious Combat Vehicle, beginning with a baseline 1.1 variant that substantially enhances protected mobility on land.

Five industry teams led by BAE Systems, General Dynamics, Lockheed Martin and other contractors are competing to develop that variant, with the Marine Corps expected to down-select to two offerors later this year (the three aforementioned companies contribute to my think tank and/or are consulting clients). About 200 of the baseline variants would be built.
