This amphibious vehicle was made by the ENJOY TECH LIMITED company, the branch plant located in the Czech Republic, in 2017. The vehicle is based on the Mercedes Sprinter car that was modied to be capable of operation on both land and water. Any authorized service can service the vehicle. The only that must be done is to dismount the bottom covers and the partition in front of the engine to enable the access to the engine and gear box. The prototype is built on the rear axle drive chassis and serves for testing the waterproof components developed by the ENJOY TECH LIMITED and for verifying the vehicle stability in water.
The prototype is equipped with the 40 kW marine propulsion. For the future, the marine JET engines are supposed to be used to obtain the highest possible speed in the water. The company takes pride in the fact that its vehicles do not feature the marine elements at rst sight, so that the vehicles do not look as "a vessel on wheels". The prototype is entirely made of steel; the original parts have been modied and re-welded. The glass bre is used only at the engine front cover to create the engine air vent. The forced-venting piping for the engine outlet air gets out up behind the driver and co-driver. The shafts also serve for draining the rainwater from the convertible top. In the left shaft, there are located the main and reserve anchor. Part of the anchors can be seen from the left side behind the driver under the vehicle body sill. It is possible to get onto the wooden parapet located under the rear windows and walk along the vehicle from the outside. The parapet also includes the mooring elements to fasten the vessel. The railing enables to fasten felders. When in the water, all doors can be opened without any restriction. Behind the doors there are partitions protecting the interior against water penetration.
In the middle above the front and rear window there are mast head lights. On the sides behind the driver and co-driver there are side navigation lights. All side windows are electrically operated as well as the backward-- folding roof. Its mechanism was developed by the ENJOY TECH LIMITED. The mechanism is covered from the bottom with cloth. The structure of the chassis transverse bracing made of stainless tubes, perforated sheet and coloured LED lighting can be seen inside on the roof.
In the interior behind the windows there is a folding shielding blind. The floor and parapets are made of teak wood. The railing, threshold frames and handrails in the interior are made of stainless steel. The interior seats were designed by the ENJOY TECH LIMITED. All seats are adjustable and there are self-inatable life jackets under each seat. The interior side walls are illuminated by diuse light. In the front part of the interior there is an LCD display depicting the forward view from the front camera located under the driver's mirror. Such all the passengers can see the same scene as the driver. In front of each passenger there is a multimedia touch screen by the Molpir-Funtoro company. The vessel control is intuitive, i.e. the sailing direction is controlled by the steering wheel and the propeller speed is controlled by the gas pedal located on the oor. On the driver's door there is a small joystick controlling the forward/backward movement. The software that reads the steering wheel revolutions and subsequently controls the direction by distributing the propeller thrust was developed by the ENJOY TECH LIMITED. On the ceiling above the driver there is a display showing the steering wheel (rudder) turn, hydraulics temperature, and other data. The display can also be utilized to diagnose a prospective fault of the marine propulsion. The marine propulsion is switched over with the single switch located on the dashboard.
The entire buffer is carved out of non-soaking foam. The rear buffer design was made by the Freestyle design. The rear window was curved directly on the vehicle. The rear face can be entirely taken out and was made by modifying the original two-leaf door. While the rear license number of the Mercedes is located on the left leaf of the door, in the case of this amphibious vehicle the license number had to be placed to the middle. The non-soaking foam is applied on the side plates up to the windows. At the bottom the 2-3 mm polyurethane paint coat is applied, altogether 170 kg. Under the coat there are several layers of the sheet and foam so that the vessel was as safe as possible. The passengers' safety is of the top priority. Regarding the prototype the rear axle had to be modified to prevent the water penetration. The axle was also extended by 240 mm. The cooler in front of the engine is located outside. When on the land the cooler is blown by air while in the water the cooler is cooled by the water bath. The air conditioning is located above the driver to enable its operation even in the water. The front lights were modified to become the waterproof ones. The air suction into the engine is done through a grille behind the front right light and subsequently via several partitions in case that the water runs into the grille. The exhaust pipe goes through the dry area and ends in the rear above the rear right light. Both the engine and gearbox are located in the machine room in the dry environment. The passenger doors are 450 mm thick and are controlled electrically. The kinematics of these doors reaches the limits of possible.
The prototype was built on a vehicle without windows and side doors in the rear part. The vehicle's unique widening already starts at the front lights. The wedge starting behind the front lights reaches its maximum width at the end of the front doors. From there up to the end, the vehicle width of 236 cm is constant. The external jacket of the front door rises along the original design while the internal jacket remains at the original position. The body work was thus extended sidewards according to the original design.
The vehicle length was selected purposely so that the car could be driven on streets of city centres without any restriction. The number of passengers is limited to 12 due to the small vessel categorization (small vessel is limited to 12 passengers). To drive the ENJOY SPRINTER amphibian, the driver must own the valid D1 driving license and the certificate for operators of pleasure craft. The ENJOY LIMITED strives to familiarize the public with amphibious vehicles and to show that it is possible to produce an amphibious car featuring up-to-date design elements. The amphibious vehicles can help during emergency situations to rescue both people and property. They are suitable for carrying construction materials or can be used as the campers for free time activities. Travel agencies can utilize these vehicles for sight-seeing tours etc. In some countries, the amphibious vehicles have already become the mean of public transportation.
The ENJOY TECH LIMITED plans to build the amphibious vehicles on the basis of a uniform chassis onto which the appropriate body will be attached according to the intended use. For example an open body, fire-fighter body, mobile home structure etc. The vehicles will be built on 6x6 chassis, i.e. three driven axles. Thus the vehicle will become the user-friendly in any terrain. Regarding the engines, the vehicle will feature the most powerful engines currently available for both land and water. The price of the 6X6 ENJOY SPRINTER vehicle with the 3.0 diesel engine, the marine JET propulsion, and with the prototype equipment starts at 9,000,000 CZK. We wish you a lot of fun with our ENJOY vehicles.
