Engines for Aurus: where they are produced, technical features and differences from analogues

Engine production for Aurus: myths and reality

When it comes to Russian premium cars, Aurus invariably takes center stage in discussions. This brand, created at the initiative of the state to provide for presidential motorcades, today also produces civilian models - Senat, Arctic, Komendant. But one of the most frequently asked questions from owners and potential buyers is: where they actually make engines for Aurus?

You can find a lot of conflicting information on the Internet - from statements about “entirely domestic development” to rumors about foreign spare parts under the hood. We analyzed official data, patent documents and expert reviews to give an accurate answer. Spoiler: the situation is not as clear-cut as it might seem.

In this article you will learn not only about the geography of production, but also about technical features of Aurus engines, their compliance with environmental standards, as well as how to distinguish an original motor from a fake. We will pay special attention to the issue of service maintenance - after all, repairing such an engine costs a tidy sum.

Official Aurus engine manufacturing plants

According to data NAMI (National Automotive Institute) and press services Aurus Motors, the main manufacturer of power units for all models of the brand is Plant named after Likhachev (ZiL) in Moscow. This is where famous people gather V8 biturbo with a volume of 4.4 liters, which are installed on Senat and Arctic.

However, this does not mean that the engines are completely Russian. The point is that ZiL carries out only final assembly and testing - about 60% of components are supplied by foreign partners. Among them:

• 🔧 Porsche Engineering (Germany) - participation in the development of engine architecture and turbocharging system
• 🔧 Bosch (Germany) - electronic control systems (ECU) and fuel equipment
• 🔧 Mahle (Germany) - pistons and elements of the cylinder-piston group
• 🔧 BorgWarner (USA) - turbochargers for biturbo versions

Interesting fact: it was originally planned that the engines would be produced at Yaroslavl Motor Plant (YaMZ), but due to sanctions and the need to quickly launch production, the choice fell on ZiL. Today YaMZ is engaged in the production of diesel units for Aurus Komendant (armored car based on Arctic).

Aurus engine specifications

The heart of all Aurus models (except diesel Komendant) is petrol V8 4.4T with two turbines. This motor has the following key parameters:

Parameter	Meaning	Note
Volume	4,395 cm³	Aluminum cylinder block
Power	598 hp (for Senat L700)	660 hp modified for Arctic
Torque	880 Nm	Available from 1,800 rpm
Compression ratio	10.5:1	Designed for AI-98 gasoline
Environmental standard	Euro 6	From 2023 - adaptation to Euro-7

The special feature of this engine is cylinder deactivation system (cylinder deactivation), which automatically switches the engine to 4-cylinder mode at low loads. This allows you to reduce fuel consumption by up to 14.5 l/100 km in the combined cycle (for a car weighing 3.5 tons this is a very good indicator).

For comparison: similar in volume V8 4.0T from Mercedes-AMG (installed on S-Class) develops 612 hp, but has less torque - 850 Nm. At the same time, the German motor is 40 kg lighter due to the use of magnesium alloys in the design.

Differences between engines for presidential and civilian Aurus

Few people know, but engines for presidential limousines (modification Senat L700 with an extended base) have a number of design differences from the “civilian” versions. Here are the key differences:

• 🛡️ Armor protection: the cylinder block and crankcase are reinforced with Kevlar inserts, capable of withstanding a 7.62 mm caliber bullet
• 🔥 Fire safety: fuel lines are duplicated and equipped with automatic shut-off valves in case of leakage
• ⚡ Electronics: two independent control units (ECU) with redundant power supply
• 🔧 Service: resource before major overhaul increased to 500,000 km (versus 300,000 km in civilian versions)

In addition, presidential engines pass individual run-in on the stand for 50 hours (versus 10 hours for serial engines). Each unit receives a unique serial number, which is entered into the closed database of the FSO (Federal Security Service).

Civilian versions use the same basic engine, but without armor protection and with a simplified diagnostic system. For example, in Senat S600 (short wheelbase) power is artificially limited to 550 hp. to reduce the tax rate.

Why don't Aurus have hybrid engines?

Initially, the Aurus project was developed as completely autonomous from foreign technologies. Hybrid systems required licensing of patents from Toyota or Honda, which was contrary to the goal of import substitution. In addition, the weight of the hybrid installation would increase the vehicle's weight to 4 tons, which would negatively affect the dynamics and life of the suspension.

Service: where to repair an Aurus engine

One of the most painful questions for Aurus owners is where can I get my engine repaired?if it fails. Today in Russia there are only 12 official service centers, accredited to work with these motors:

• 📍 Moscow (2 centers: on Dmitrovskoe highway and in Ochakovo)
• 📍 St. Petersburg (Sedova st., 60)
• 📍 Kazan (Dekabristov st., 135)
• 📍 Ekaterinburg (Repina st., 100)
• 📍 Sochi (Vinogradnaya st., 18)

The cost of a major overhaul of an Aurus V8 engine starts from 2.8 million rubles (excluding spare parts). For comparison: capital Mercedes V8 costs 1.2–1.5 million rubles. This difference is explained:

1. The need to use specialized equipment (for example, a stand for balancing a crankshaft costs 15 million rubles)
2. Limited release of spare parts (many parts are made to order)
3. Requirements for the qualifications of masters (training takes 6 months)

Fun fact: in 2023 Aurus Motors launched an engine exchange program at a fixed price - 4.5 million rubles for a new unit (including labor). This is 20% cheaper than buying a motor separately + installing it.

Frequent problems and weaknesses of Aurus engines

Despite the declared resource of 500,000 km, owners and service engineers identify several typical problems that Aurus engines encounter:

⚠️ Attention: The most vulnerable point is BorgWarner turbochargers. When using low-quality oil or exceeding the replacement interval (more than 10,000 km), the turbine shaft becomes jammed. Repairs cost 800,000–1,200,000 rubles per turbine.

Other common faults:

• 🔥 Overheating: due to the compact engine compartment in Senat Ignition coils often overheat (the solution is to install additional airflow)
• 🛢️ Oil leaks: crankshaft and camshaft seals begin to “sweat” after 80,000–100,000 km (replacement required with engine disassembly)
• 🔊 Knock of hydraulic compensators: appears during a cold start, is eliminated by flushing the oil system with a special compound (the cost of the procedure is 45,000 rubles)

The problem with electronic control unit (ECU). Due to the use of uncertified software (for example, during chip tuning), the unit may become “blocked” and require flashing at the factory. The cost of this service is from 300,000 rubles.

Prospects: new engines for Aurus after 2026

In 2026 Aurus Motors announced the start of work on new family of engines, which should replace the current V8. Among the key novelties:

• 🔋 Hybrid installation: combination of 3.0-liter V6 biturbo (450 hp) with an electric motor (120 kW), which should reduce fuel consumption to 9 l/100 km
• ⚡ 48 volt system: Replacement of traditional 12-volt equipment to improve efficiency
• 🌍 Adaptation for hydrogen: experimental samples of engines capable of running on hydrogen fuel are already being tested at the NAMI test site

The first car with the new engine will be Aurus Senat second generation, set to debut in 2026. Interestingly, for this project US collaborates with Kama Automobile Plant (KAMAZ) — the latter will be responsible for the production of aluminum cylinder blocks.

According to preliminary data, new V6 3.0T will be 30% lighter than the current V8, which will improve acceleration dynamics (0–100 km/h in 4.5 seconds versus the current 5.5 s). In this case, the torque will remain at 800 Nm, but will be available from 1,500 rpm.

How to distinguish an original Aurus engine from a fake

Offers have already appeared on the secondary market for the sale of “contract” engines for Aurus from Europe and Asia. However, according to FSB Expert Center, up to 40% of such units are fakes or relabeled engines from other cars (most often from BMW N63 or Mercedes M177).

Here 5 signs of an original Aurus engine:

1. Serial number: must start with letters AM (Aurus Motors) and contain 12 digits. The number is laser-etched onto the cylinder block and is duplicated on a metal plate under the hood.
2. Valve cover: Logo engraved on the original Aurus (double-headed eagle) and inscription Made in Russia.
3. Turbines: there must be a logo on the case BorgWarner and article number BW K04-2057.
4. Electronic unit: The original ECU has a green board with the inscription NAMI ECU v3.1.
5. Wiring color: the wire harnesses are wrapped in black heat-shrink tubing with red marks (counterfeits often use blue insulation).

⚠️ Attention: When purchasing a used engine, be sure to request FSB certificate of conformity (issued when recycling cars of the presidential fleet). Without this document, the engine will not be registered with the traffic police when installed on another Aurus.

The cost of the original contract Aurus V8 engine today is 3.2–3.8 million rubles (depending on mileage). Counterfeits can be found for 1.8–2.5 million rubles, but their installation is fraught with problems with electronics and a reduction in service life by 40–50%.

FAQ: Frequently asked questions about Aurus engines

Is it possible to install an Aurus engine on another car (for example, on a UAZ)?

Technically this is possible, but it will require a complete rework of the electronics, transmission and cooling system. The cost of such tuning will exceed 5 million rubles, and legalization by the traffic police will be practically impossible due to the lack of certificates of conformity for other brands.

Which oil is recommended for the Aurus V8 engine?

The manufacturer recommends using only Lukoil Genesis Armortech 5W-40 (article 1539650) or Rosneft Magnum Ultra 5W-40 (article RN-540). These oils have special additives to protect turbines and meet the standard API SN PLUS.

How much does it cost to replace a timing belt on an Aurus?

In an official service center, replacing a timing belt costs 180,000–220,000 rubles (including work and original set of belt, rollers and pump). Replacement interval is every 120,000 km or 5 years (whichever comes first).

Is it possible to drive on 95 gasoline instead of 98?

Strongly not recommended. The Aurus V8 engine has a compression ratio of 10.5:1, which requires an octane rating of at least 98. Using 95-octane gasoline will lead to detonation, damage to the pistons and a reduction in turbine life. In emergency cases, a one-time refueling with 95-octane gasoline with an octane-increasing additive (for example, Liqui Moly Oktan Plus).

Where can I buy spare parts for the Aurus engine?

Original spare parts are sold only through the dealer network Aurus Motors or certified service centers. Alternative options:

• 🛒 Official online store Aurus Motors (delivery within Russia 5–7 days)
• 🛒 Exist.ru — there is a limited range of consumables (filters, candles)
• 🛒 AvtoVAZ-Leasing — supplies some parts upon request (waiting period up to 30 days)

The cost of original spare parts is 2–3 times higher than that of analogues. For example, a set of spark plugs Beru Z322 costs 48,000 rubles (versus 12,000 rubles for analogues from NGK).
