Choosing a Nissan Murano crossover often comes down to the question of which powertrain is best suited for your needs. Most potential buyers are interested in how exactly engine capacity affects the dynamics, reliability and cost of operating this car. Understanding the differences between the modifications will help you avoid mistakes when buying a used one.
Throughout the history of the model's production, the company's engineers changed the power plants, adapting them to new environmental standards and market requirements. If you are considering Nissan Murano first or second generation, then you will mainly encounter naturally aspirated engines of the VQ series. More recent versions may offer other technical solutions, but it is the V-shaped “sixes” that have become the hallmark of the brand in this class.
It is important to understand that volume determines not only power, but also the nature of acceleration, as well as the behavior of the car in traffic jams or on the highway. Some drivers prefer economical options, while others are looking for a reserve of traction for active driving. Let us examine in detail which units were installed in different years of production and what their real capabilities are.
History of motors and main series of engines
The heart of most versions Nissan Murano is the legendary VQ engine series. These powerplants are known for their smooth operation and long life if properly maintained. The main volume that can be found on the roads is 3.5 liters. Exactly like this working volume allows the crossover to develop sufficient power for confident overtaking.
At the start of production of the model, engineers offered a unit with the VQ35DE index, which was distinguished by high responsiveness and good traction at low speeds. Later, during the modernization, the VQ35DE variant appeared with a variable valve timing system (VVEL), which improved fuel combustion efficiency. In newer generations, the engines received the VR35DE index, becoming even more technologically advanced.
Despite the fact that there are diesel versions on the market for the European market, in Russia and the CIS countries it is gasoline units that dominate. This is due to the climate and the availability of high-quality fuel. Volume 3.5 liters has become the de facto standard for this segment, providing a balance between power and acceptable consumption in urban conditions.
⚠️ Attention: When buying a used car, be sure to check the engine service history, as oil starvation is critical for VQ series engines.
- The VQ35 series is a classic naturally aspirated engine with a capacity of 3498 cc. cm.
- The presence of the VVEL system provides better fuel efficiency in the urban cycle.
- VR series motors feature reduced friction and an improved cooling system.
Characteristics of first and second generation engines
The first generation of the model, produced from 2002 to 2007, was equipped with only one type of engine. It was a 3.5 liter VQ35DE unit. It produced about 230-245 horsepower, depending on the market and year of manufacture. Such power reserve was quite sufficient for a crossover weighing about 1.8 tons.
The second generation, which replaced the first in 2008, retained the same basic engine size, but with new technologies. Engineers have optimized the intake tract and engine management system. As a result, power increased to 265 hp and torque increased. It did Nissan Murano the second generation is more dynamic without sacrificing comfort.
Particular attention should be paid to the ALL-WHEEL DRIVE all-wheel drive system, which was paired with these engines. It effectively distributed torque between the axles, which was especially important when operating a powerful engine in difficult road conditions. However, it is worth remembering that the large weight of the car and engine volume require high-quality oil and timely replacement.
Despite their reliability, engines of this period have their own characteristics. For example, the variable valve timing system may require attention at high mileage. It is also important to monitor the condition of the chain tensioners, as their wear can lead to serious consequences for valve mechanism.
- The power of the first generation engines varies from 230 to 245 hp.
- In the second generation, power was increased to 265 hp. by optimizing the intake.
- Both generations use the same basic 3.5-liter cylinder block.
- Atmospheric V6
- Turbocharged
- Hybrid
- Diesel
Third generation engines and modern technologies
The third generation of the model, released in 2015, was marked by the transition to a new VR series motor. Although engine capacity remained the same - 3.5 liters, the design itself was significantly redesigned. The new unit received the VR35DE index and became lighter and more compact than its predecessor.
Engineers used double variable valve timing technology at the intake and exhaust. This made it possible to achieve higher fuel combustion efficiency and reduce emissions of harmful substances. The power of the new engine was 249 hp, which is slightly lower than that of the previous generation, but actual acceleration has become more linear and predictable.
An important feature of the third generation is integration with the Xtronic CVT. This unit is perfectly adapted to the characteristics of the VR35DE engine, ensuring smooth running and no jerking. However, the variator requires special attention during operation, especially in conditions of slipping or prolonged operation at high speeds.
For those looking for maximum dynamics, it is worth noting that the new motors have a wider range of effective operation. This allows you to feel confident both in the city and on highways. Nevertheless, volume 3.5 liters is still a compromise between power and economy.
- The new VR35DE motor has lower noise and vibration levels.
- Reducing the weight of the engine improved the car's weight distribution and handling.
- The engine management system has become more adaptive to driving style.
What you need to know about fuel consumption?
The actual fuel consumption of a Nissan Murano with a 3.5 liter engine in the urban cycle is 13-15 liters per 100 km. On the highway this figure drops to 9-10 liters. In winter and in traffic jams, consumption can reach 17-18 liters, especially when using the all-wheel drive system in active mode.
The influence of engine volume on fuel consumption
Many owners are interested in how exactly engine capacity affects operating costs. With a volume of 3.5 liters, the crossover consumes a significant amount of fuel, but this is a price to pay for power and comfort. Unlike small-displacement engines, there is no need to constantly “turn” the engine to achieve the desired speed.
In the urban cycle, fuel consumption can be quite high, especially during rush hours. This is due to frequent stops and starts where the engine runs at low speeds but consumes a lot of fuel to maintain thrust. On the highway, with uniform movement, the consumption stabilizes and becomes quite acceptable for a car of this class.
The all-wheel drive system also contributes to increased consumption. It draws energy from the engine to operate the clutch and gearboxes, which inevitably affects fuel efficiency. However, without all-wheel drive Nissan Murano loses its off-road qualities, which owners value so much.
To reduce consumption, it is recommended to use high-quality gasoline and undergo regular maintenance. Clogged injectors or worn spark plugs can increase fuel consumption by 10-15%. It is also important to monitor tire pressure, as low tire pressure increases rolling resistance.

Reliability and service life of power units
The service life of Nissan VQ and VR series engines is considered one of the best in its class. With proper maintenance, they can travel more than 300 thousand kilometers without major repairs. The key factor here is timely oil changes and the use of original consumables.
However, there are also weaknesses that you need to be aware of. These include the variable valve timing system, which may require replacement at high mileage, as well as chain tensioners. It is also worth paying attention to the condition of the gaskets, as they may begin to leak over time.
The cooling system must work flawlessly, as overheating can lead to deformation of the cylinder head and costly repairs. Regular checking of the coolant level and radiator condition is mandatory.
⚠️ Attention: Use only motor oil with the approval recommended by the manufacturer, and change it at least once every 7-8 thousand kilometers in city conditions.
Many owners note that even after 200 thousand kilometers the engine maintains good dynamics and efficiency. This indicates the high quality of materials and precision manufacturing of parts. The main thing is not to ignore the first signs of malfunctions and respond in a timely manner to changes in engine operation.
- The average engine life is 300-350 thousand kilometers.
- The critical elements are the chain tensioners and the VVEL system.
- Engine overheating is the main cause of cylinder head failure.
Timely maintenance and the use of high-quality consumables are the key to a long life of the Nissan Murano engine.
Engine Specifications Table
For clarity, let’s compare the main parameters of the engines that were installed on different generations of the model. This will help you choose the appropriate option depending on your priorities: dynamics or efficiency.
| Generation | Engine model | Volume (l) | Power (hp) | Torque (Nm) |
|---|---|---|---|---|
| First (Z50) | VQ35DE | 3.5 | 230-245 | 326 |
| Second (Z51) | VQ35DE (VVEL) | 3.5 | 265 | 333 |
| Third (Z52) | VR35DE | 3.5 | 249 | 325 |
| Fourth (Z53) | VC-Turbo | 2.0 | 201 | 350 |
As can be seen from the table, despite different generations and indexes, the engine size remains unchanged over three generations. The fourth generation offers a turbocharged variant with smaller displacement but higher torque. This is a modern trend to reduce volume while maintaining power through turbocharging.
The choice between naturally aspirated and turbocharged engines depends on your preferences. Aspirated engines are easier to maintain and repair, while turbocharged engines provide better dynamics with lower fuel consumption. However, the complexity of the turbocharger design requires more careful maintenance.
⚠️ Attention: When purchasing a turbocharged version, you must pay special attention to the condition of the cooling system and oil quality, since the turbine operates in extreme temperature conditions.
Before purchasing a car with a turbocharged engine, be sure to check the condition of the intercooler and charging system, as replacing them can be very expensive.
Features of maintenance and operation
Maintenance of the Nissan Murano engine does not require special skills, but it has its own nuances. The use of original spare parts and recommended fluids is the basis for long and reliable operation of the unit. Incorrectly selected oil can lead to coking of the channels and reduced cooling efficiency.
Regular diagnostics of the ignition and injection system is also important. Spark plugs and coils must be replaced in accordance with regulations. Ignoring these procedures may result in a misfire, which in turn damages the catalytic converter.
For owners with high mileage, checking the condition of the timing chains is especially important. If you hear a metallic clicking sound when starting the engine, this may be a sign of a stretched chain. In this case, you must contact service for a replacement as soon as possible.
It is also worth paying attention to the crankcase ventilation system. Clogged valves can lead to increased pressure in the crankcase and squeezed out seals. This is a common problem on older cars and can be resolved by replacing the ventilation valve.
