The question of what kind of engine is hiding under the hood of Russian premium cars Aurus, worries not only potential buyers, but also all those who are not indifferent to the domestic automotive industry. AurusThe turbocharged V8, which has become a symbol of the resurgence of the luxury segment in Russia, was originally created with ambitious plans to equip advanced power plants, the basis of the lineup was the gasoline turbocharged V8, developed in cooperation with Porsche Engineering, which immediately set the bar for expectations for performance and reliability.

But when asked what engine is in AURUS, you can't just go with the petrol version. The modern car industry dictates its own rules, and Russian engineers have made the case for it. hybrid Mild-Hybrid, which not only increases power but also reduces fuel consumption, which is critical for a heavy business sedan. In this article, we will discuss in detail the specifications, design features and real performance indicators of the powertrains installed on the model. Aurus Senat and Aurus Komendant.

The uniqueness of the project lies in the fact that the NAMI-4123 engine was developed from scratch, taking into account the specifics of operation in harsh Russian conditions. Power And the torque was tailored to deliver the same dynamics as the best BMWs or Mercedes-Benz models in the world, and then we'll look at how the heart of this car works and why it's the one that's chosen.

Design and specifications of the V8 gasoline

The basis of the power range is an internal combustion engine with a volume of 4.4 liters. V8 The twin-turbo Twin-Turbo is a sophisticated engineering product developed at the Automotive and Automotive Research Institute (NAMI), a block of aluminum that reduces the overall weight of the powertrain while maintaining the necessary rigidity for high-load operation.

The engine’s performance is impressive even in its basic configuration, and with direct fuel injection and modern control, engineers have been able to take a tremendous amount of power out of a displacement that seems modest for a car of this class and weight. Torque. Available in a wide range of revs, which provides confident acceleration at any speed, whether it is starting from a traffic light or overtaking on the track.

It is important to note the lubrication and cooling system, which has been adapted to operate in extreme temperature conditions. NAMI-4123 It is able to work stably both in severe frosts and under prolonged loads in the summer heat, which is a mandatory requirement for state-level cars.

⚠️ Attention: Use of non-original oils or low-quality fuels can cause permanent damage to the turbochargers and direct injection system.

And we also have a phase distribution system that allows you to optimize your engine performance based on your driving mode. turbo engineA complex system where each valve and each stroke of the pistons is controlled electronically to achieve maximum efficiency.

To extend the life of the turbines on the Aurus, it is recommended to allow the engine to work at idle speeds for about 30-60 seconds after an active drive before turning off the ignition.

Hybrid power plant Mild-Hybrid

The answer to the question of which engine in AURUS is incomplete without a detailed examination of the electrical component. power-system Mild-Hybrid: It doesn’t allow a car to travel long distances purely on electric power, like full-fledged hybrids, but it does a number of critical functions to improve performance.

The main element here is the starter generator, which is integrated into the design of the transmission, which takes over the function of starting the engine, making this process completely silent and instantaneous. In addition, the electric motor adds additional traction during acceleration, eliminating the effect of "turboholes" and making acceleration smoother and more linear.

The hybrid component is also responsible for the operation of the system. Start-StopIt's a system that shuts down the engine at traffic lights to save fuel, and with a 48-volt network, it starts so fast and so quietly that the driver and passengers barely notice when the engine is turned on, and the battery of the system recovers the braking energy, storing it for later use.

  • πŸ”‹ Starter-generator provides instant start and smooth operation of the start-stop system.
  • ⚑ Recovery It allows you to save the energy of inertia during braking and use it for acceleration.
  • πŸš€ Additional traction The electric motor helps the gasoline engine at peak loads.
  • πŸ“‰ Reduced consumption Fuel is achieved through more efficient management of the internal combustion engine.

Thus, Mild-Hybrid In AURUS, it's not a marketing ploy, but a real-world mechanism that increases comfort and efficiency, and electronics instantly distributes tasks between the gasoline engine and the electric motor, ensuring optimal operation in any situation.

Transmission: 9-speed automatic RAKHAT

No matter how powerful the engine was in AURUS, without the effective transmission of torque to the wheels, its potential would remain untapped. RAKHATThe name comes from the Tatar word meaning "comfort" or "comfort", which fully reflects the philosophy of setting the unit.

This transmission is capable of digesting the high torque of 590 Nm, which gives the power unit. The presence of nine stages allows you to keep the engine speed in the most economical range when driving on the road, and also provides a very smooth shifting of gears that the driver of the premium sedan does not need to feel physically. Hydrotransformer Here he acts as a damper, smoothing any jerks.

Algorithms of work RAKHAT They're designed to be comfortable, but when you switch to sports mode, the box responds much faster, keeping the gear at high speeds longer, which makes the car more gambling when necessary, and the box also has an all-wheel drive system that can throw the moment between the axles depending on which one.

The developers have focused on friction reliability and the cooling system of the transmission fluid. Aurus SenatWith a gearbox that exceeds two tons, the safety margin of the transmission should be enormous, and engineering solutions confirm this approach.

Why 9 steps?

Increasing the number of gears reduces the gap between gear ratios, making the switching less noticeable to the passenger and allowing the engine to always be in the zone of optimal efficiency, which reduces fuel consumption and noise.

Dynamic indicators and effectiveness

Many motorists are interested in what dynamics such a heavy car can offer. Aurus Senat Acceleration to 100 km / h takes about 5.7-5.9 seconds, which for a sedan longer than 5 meters is an excellent result.

The maximum speed is electronically limited to 250 km/h, which is the standard for cars in this segment, but the most important thing is not the maximum speed, but the elasticity of acceleration in the speed range of 80-120 km/h, where the power reserve is more important. V8 allows you to make safe overtaking without the need for emergency pressing of the gas pedal into the floor.

In terms of fuel consumption, the situation is typical for high-power turbocharged engines: in an urban cycle, taking into account traffic jams and frequent starts, the consumption can reach 15-17 liters per 100 km. On the highway at a speed of 110-120 km / h, it is possible to meet 10-11% of liters due to the long last gear and operation of the hybrid system.

  • 🏁 Acceleration 0-100 km/h: 5.7–5.9 seconds.

Comparison with competitors: Mercedes, BMW, Audi

To understand the Aurus’ position in the global market, you need to compare its powertrain to its direct competitors: The main rivals are the Mercedes-Benz S-Class (for example, the S 500 with a straight six or V8), the BMW 7-Series and the Audi A8. Which engine in the AURUS wins this fight?

German competitors have been moving to 3.0-liter inline six-cylinder engines with electric trains in recent years, while the Aurus has retained the classic 4.4-liter V8, giving the Russian car an advantage in engine sound and traction margin at very low rpm. V8 It sounds nobler and works softer than the "six", which is an important image factor for the representative class.

The Aurus is not inferior in power and torque to many of its competitors’ basic versions, but the German engineering school is famous for its years-long reliability and filigree in the configuration of its transmissions. Aurus Here it acts as a catch-up, but the gap is already minimal, especially in real-world conditions, where both types of motors show high efficiency.

⚠️ Note: Direct comparison of data-sheet figures may not be correct without considering the weight of the car. Aurus Senat is heavier than many analogues, so its dynamic performance should be evaluated adjusted for weight.

The uniqueness of the Russian approach lies in adapting to local conditions, while European engines can be sensitive to fuel quality and temperature changes, the engine is not a problem. Us The project was designed with the expectation of Russian realities, which gives it a certain advantage in reliability in our latitudes.

Engine resource and features of maintenance

The question of durability is one of the most important for owners. engine resource NAMI-4123 The use of an aluminum block with shells and modern piston group materials allows you to expect hundreds of thousands of kilometers of mileage, subject to timely maintenance.

However, like any modern motor, it requires high-quality serviceOil replacement intervals should be reduced to 7,000 to 8,000 kilometers, especially if the car is mainly in the city, and turbines operating at high temperatures require clean oil and a proper ventilation system for the crankcase.

Maintenance complexity may be higher than that of aspirated engines of the past, due to the high density of the layout and the presence of hybrid elements.

  • πŸ›’οΈ Oil replacements: every 7,000 to 8,000 km.
  • πŸ”§ Spark plugs: Replacement every time 60,000 km.
  • ❄️ Antifreeze: check the level and condition each 15,000 km.
  • πŸ’» Diagnostics: at each planned.

Owners should be prepared to have parts and work that are in line with the class of the car, but the safety margin is appropriate. motor It can serve faithfully for many years without requiring any major intervention.

The main secret of the long life of the Aurus engine is high-quality fuel and shorter engine oil replacement intervals, especially in winter.

Which octane of gasoline is best used for Aurus?

For the NAMI-4123 engine installed in Aurus, the manufacturer recommends using gasoline with an octane number not lower than AI-95. However, to achieve passport power and maximum efficiency of turbines and direct injection system, gasoline is the best choice. AI-98 The use of lower quality fuels can lead to detonation and a decrease in the life of the engine.

Does Aurus have a diesel engine version?

Currently, only 4.4-litre petrol V8s combined with a hybrid are available in series production and the official engine line for the Aurus Senat and Komendant models. Information about the development or plans for diesel modifications has not been officially confirmed, as the brand concept is focused on the quietness and smoothness that the gasoline V8 provides better.

Is it difficult to find spare parts for the Aurus engine?

Since the car is manufactured in Russia and the localization of production is high, problems with original engine parts should not be within the official dealer network. Many components are unified or produced at Russian facilities.
