When studying the specifications of the Sadko NEXT 4x4 SUV, the technical characteristics immediately indicate the dominance of the power unit YaMZ-534, which radically changes the dynamics of movement compared to its predecessors. This 4.43-liter diesel engine provides a torque of 735 Nm, which allows you to confidently overcome fords up to 1.2 meters deep and climbs with a slope of up to 60%. The designers retained the legendary cross-country ability, but significantly modernized the power frame and transmission, focusing on reliability in extreme operating conditions.
A secondary but critical aspect is the new cabin, adapted from the LAWN NEXT, which offers a completely different level of ergonomics. The driver receives a three-seater cabin with improved sound insulation and air suspension, which reduces fatigue during long hauls. All-wheel drive system Full-time 4WD with a center differential and wheel gear locks, it provides traction where conventional vehicles lose traction.
โ ๏ธ Attention: Despite the high maneuverability, the standard winch has a limitation in force, so when working with maximum loads, an additional anchor or the help of another vehicle is required.
Engine and powerplantThe heart of the car is an inline four-cylinder turbocharged diesel engine developed in Yaroslavl. Engine YaMZ-53441-10 complies with the environmental standard Euro-4 (with the possibility of upgrading to Euro-5) and is highly maintainable. The presence of a Common Rail system allows you to accurately dose fuel, which has a positive effect on efficiency and stability at idle speed.
Cooling system parts
The engine cooling system is liquid, closed type with forced circulation. The radiator has an increased cooling area, which is critical for operating in high temperatures at low speeds.

To protect the power units, a dual-circuit lubrication system with an oil heat exchanger is used. The engine lifespan before the first major overhaul is stated by the manufacturer at the level of 450-500 thousand kilometers, which is an excellent indicator for special equipment of this class. A variable geometry turbocharger ensures no turbo lag and smooth thrust throughout the entire rev range.
Transmission and chassisTorque is transmitted through a dry single-plate clutch with a hydraulic release drive, the service life of which is designed for harsh operating conditions. The gearbox is manual, five-speed, synchronized in all forward gears except first. Transfer case two-stage, with a center differential, which is locked by a pneumatic drive from the cab.
The main feature of the transmission is the ability to engage all-wheel drive while driving without stopping the vehicle, which is critically important when driving on slippery sections of the road.

The chassis is based on axles with wheel reduction gears, which provides enormous ground clearance. The ground clearance under the bridges is an impressive 385 mm, allowing the car not to โsit on its bellyโ even on very rough terrain. Semi-elliptical springs, front and rear, with additional springs that come into play when the vehicle is fully loaded.
- ๐ Drive type: All-wheel drive (4x4) with a permanent base.
- ๐ Locks: Inter-axle and inter-wheel (pneumatic).
- ๐ Main gear ratio: 5.125.
Dimensions, weight and capacityThe overall dimensions of the Sadko NEXT 4x4 are optimized for maneuvering in the forest and narrow technological passages. The length of the car is 5635 mm, width - 2340 mm, and cabin height - 2520 mm. These dimensions allow the equipment to pass between trees and fit into the dimensions of most bridges and overpasses.
The total vehicle weight reaches 7700 kg, while the curb weight is about 5100 kg. Load capacity in the flatbed varies depending on tire type and configuration, but is typically around 2,000 kg. The fuel tank volume has been increased to 105 liters, which provides a highway range of more than 800 kilometers without refueling.
| Parameter | Meaning | Unit measurements |
|---|---|---|
| Ground clearance | 385 | mm |
| Turning radius | 9,5 | m |
| Approach angle | 45 | degrees |
| Fordable | 1200 | mm |
Cabin and driver comfortThe cabin is all-metal, three-seater, with a high roof and improved visibility. Unlike its predecessors, here we use panoramic windows and an efficient ventilation and heating system. The driver's seat is pneumatic, with many adjustments, which reduces the vibration load on the spine when driving over rough terrain.
The instrument panel is ergonomic and contains all the necessary indicators for monitoring vehicle systems. Pressure indicators in the pneumatic system, coolant temperature and oil pressure are located here. The lighting of the cabin and the driver's workplace meets modern safety standards, reducing eye fatigue at night.
Fuel consumption and efficiencyThe issue of fuel consumption for such equipment is always relevant. The average fuel consumption of the Sadko NEXT 4x4 when driving on the highway at a speed of 60 km/h is about 18-20 liters per 100 kilometers. However, when driving in difficult road conditions or when operating attachments, this figure can increase significantly.
โ ๏ธ Attention: Actual fuel consumption directly depends on driving style and the use of differential locks, which increase rolling resistance.
To improve efficiency, it is recommended to use driving modes appropriate to the type of surface. The engine management system allows you to optimize the operation of the injectors, but overloading the vehicle above the rated values โโleads to excessive consumption and a decrease in the resource of the power unit.
Features of operation in extreme conditionsThe vehicle is designed to operate in a wide temperature range from -45 to +50 degrees Celsius. The pre-heating system (optional) makes starting easier in severe frosts. All electrical connections are highly waterproof, and the body is treated with anti-corrosion compounds for use in aggressive environments.

When operating in mountainous areas, it is important to take into account the thin air, although turbocharging partially compensates for the loss of power. The pneumatic brake system with ABS (optional) ensures safe braking even on slippery slopes. Regularly checking the tightness of wheel gear seals is a mandatory procedure after overcoming water obstacles.
Maintenance and maintenance intervalsRoutine maintenance is carried out at certain mileage or engine hour intervals. Engine oil is changed every 15-20 thousand kilometers, depending on operating conditions. Taking into account the quality of diesel fuel in remote areas, it is recommended to change fuel system filters more often than required.
Use only manufacturer-recommended wheel drive lubricants, as conventional gear oils can foam at high speeds.

Access to the main components for maintenance is simplified thanks to the folding cab and thoughtful layout of the engine compartment. Diagnostic connector allows you to connect scanners to read error codes and monitor engine operating parameters in real time.
What is the real fuel consumption of the Sadko NEXT 4x4?
In a combined cycle, the actual consumption is 22-25 liters of diesel fuel. On off-road conditions with frequent slipping and winch operation, consumption can reach 30-35 liters per 100 km.
Do you need a category C license to drive Sadko?
Yes, the gross vehicle weight exceeds 3500 kg (7700 kg), so a category C driver's license is required to drive.
Is it possible to install other engines on Sadko NEXT?
It is theoretically possible to install other engines, but this will require serious modifications to the frame, transmission and control systems, which is not economically feasible.
What is the maximum speed of the car?
The maximum technical speed of the Sadko NEXT 4x4 is about 95-100 km/h, however, operating the vehicle at such speeds off-road is prohibited due to the risk of capsizing.
