Nissan Murano Engine Size: The Complete Technical Encyclopedia

Choosing a mid-class crossover often comes down to finding the perfect balance between dynamics and comfort, where the powertrain plays a key role. For model Nissan Murano this problem was solved by the company's engineers by using time-tested naturally aspirated engines of the VQ family, which became the hallmark of the brand. If you're considering buying a used car or looking for maintenance information, understanding the differences between generations and engine sizes will be a deciding factor.

The entire line of crossovers Nissan Murano Throughout its history, it has been equipped exclusively with gasoline units with a V-shaped cylinder arrangement, which provides excellent vibration stability. The abandonment of turbocharged solutions or diesel engines was a deliberate move in favor of the reliability and smoothness characteristic of the American market. It is important to consider that engine size directly affects the acceleration pattern, overtaking dynamics and, importantly, fuel consumption in various operating modes.

The history of the transformation of crossover power units

The first generation of the model, which appeared on the market in 2002, immediately attracted the public's attention with its futuristic design and powerful heart under the hood. It was based on the legendary engine VQ35DE volume of 3.5 liters, which developed impressive power and provided excellent elasticity. This unit has become the standard for the entire segment, demonstrating that a crossover can be not only a family car, but also a means of providing emotional driving pleasure.

With the release of the second generation in 2008, engineers did not radically change the architecture, but carried out a deep modernization of the existing cylinder block. Motor VQ35DE received new phase shifters and a CVTCS variable valve timing system, which increased power and reduced exhaust emissions. In the third generation, launched in 2014, there was a qualitative leap: the engine was replaced with a more modern and technological one VQ35V volume of 3.6 liters, which became available in a version with all-wheel drive.

Despite external changes and updating of the line, the philosophy of the engineers remained unchanged: priority is given to naturally aspirated engines that do not require complex maintenance of turbochargers or particulate filters. It does Nissan Murano an attractive option for regions with harsh climates and difficult road conditions. Owners often note that it is the simplicity of the engine design that is the main advantage over competitors offering complex hybrid or turbocharged solutions.

⚠️ Attention: When purchasing a used car, be sure to check the engine service history, as untimely oil changes can lead to stuck piston rings and reduced compression.

VQ35DE engine: A classic of Japanese engine building

Motor VQ35DE with a volume of 3.5 liters, this is perhaps the most famous unit in the history of the company Nissan. It has been installed in a variety of models, from sports coupes to minivans, and has proven to be one of the most reliable engines in its class. In the context of a crossover Murano this engine provides power ranging from 234 to 249 horsepower, depending on the year of manufacture and drive version. Its characteristic feature is high torque, available at low speeds, which is critical for a heavy SUV.

The cylinder block design is made of aluminum alloy, which reduces the overall weight of the vehicle and improves weight distribution. The cylinder liners have a special coating that increases wear resistance and heat dissipation. The gas distribution system is equipped with two camshafts per cylinder head (DOHC) and 24 valves, which allows you to effectively fill the cylinders with mixture at high speeds. For owners, this means that the car can easily handle overtaking on the highway without the need to constantly maintain a high crankshaft speed.

However, any technical solution has its own operating characteristics that must be taken into account during long-term operation. Engine cooling system VQ35DE is sensitive to the condition of the thermostat and pump, and the timing belt requires replacement strictly according to regulations in order to avoid critical damage. It is also worth paying attention to the crankcase ventilation system, which can become clogged over time, leading to increased oil consumption.

• ✅ High maintainability: wide selection of spare parts and analogues on the market.
• ✅ Excellent dynamics: acceleration to 100 km/h in 7.5–8.5 seconds.
• ✅ Reliability: engine life with proper care exceeds 400,000 km.

Many owners note that after 100,000 kilometers, the engine begins to require more careful attention to the ignition and fuel supply systems. Spark plugs and coils are consumables that should be changed preventively. Failure to follow this rule can lead to misfire, which in turn causes overheating of the catalytic converter and its expensive replacement.

Upgraded VQ35V: Evolution of volume and power

In the third generation Nissan Murano received an updated version of the engine, which is often called VQ35V or simply VQ35DD, although technically the volume remained close to 3.5 liters, but with modifications. However, in some markets and trim levels, especially in the US, the volume is 3.6 liters, which is due to changes in the piston stroke and cylinder diameter to improve efficiency. This unit develops power up to 260–265 hp, providing even more confident traction at high speeds.

The main difference of the new engine is the use of direct fuel injection and a more advanced variable valve timing system. This allows you to achieve better environmental performance without loss of power. The engine management system has become more complex, integrated with the CVT gearbox, which ensures smooth gear changes and no jerking during acceleration. For the driver, this means comfortable movement around the city and on the highway, where the car feels like a light sedan.

However, the increasing complexity of the design has led to the emergence of new vulnerabilities. Direct injection injectors are more sensitive to fuel quality and require regular cleaning. Also, the variable valve timing system relies on oil pressure, so the use of low-quality lubricants can lead to failure of the phase shifters. This is a critical point for those who plan to operate the car in hot climates or with frequent short trips.

⚠️ Warning: Using fuel with a lower octane rating (usually 95 or 98) may cause detonation, which destroys the piston group of the VQ35V engine.

• 🚀 Increased power: up to 265 hp for better dynamics.
• 🌱 Environmental friendliness: compliance with Euro-5 and Euro-6 standards.
• 🛠️ Difficulty of repair: Requires specialized diagnostic equipment.

It is important to understand that switching to direct injection is not always a panacea for reducing fuel consumption. In urban conditions, with frequent traffic jams, a direct injection engine can consume even more fuel than its predecessor with distributed injection, due to more complex operating cycles. Therefore, when choosing a version, it is worth considering your type of use: if it is mainly city driving, the savings may not be as obvious as the manufacturer promises.

Real fuel consumption: myths and facts

One of the most common questions potential buyers ask is about fuel consumption. Official manufacturer data often looks optimistic, but actual operation makes its own adjustments. For an engine with a volume of 3.5–3.6 liters in the urban cycle, the average consumption is from 13 to 16 liters per 100 kilometers, depending on driving style and road congestion. On the highway at a speed of 90–100 km/h this figure drops to 8–10 liters, which is an excellent result for a heavy crossover.

In winter, fuel consumption may increase by 20–30% due to engine warming up, the use of a heater and winter tires. It is also worth considering that the all-wheel drive system Nissan has an electromagnetic clutch that connects the rear wheels when slipping. In permanent all-wheel drive mode, which is sometimes used off-road or in icy conditions, fuel consumption increases even more. If you often travel around the city during rush hour, prepare for the average consumption to be close to 17–18 liters.

Many owners try to reduce fuel consumption using various methods: from installing additional equipment to changing their driving style. However, it is worth remembering that a naturally aspirated engine with a volume of more than 3 liters physically cannot be as economical as a small turbocharged engine. The average real fuel consumption for the Nissan Murano with the VQ35 engine is 14.5 liters per 100 km in the combined cycle. This is an honest figure that you should focus on when planning your operating budget.

• 🚦 Urban cycle: 14–16 l/100 km (including traffic jams).
• 🛣️ Route: 8.5–10 l/100 km (with quiet driving).
• ❄️ Winter: +3–4 liters to the urban cycle.

To optimize fuel consumption, it is recommended to regularly check tire pressure and use high-quality low-viscosity engine oil recommended by the manufacturer. You should also avoid sudden acceleration and braking, as a large engine quickly gains speed and consumes a lot of fuel. A smooth ride is not only comfort, but also savings.

Maintenance features and engine life

Engine life Nissan Murano directly depends on the quality of service and operating conditions. If all regulations are followed and original spare parts are used, the engine can travel more than 400,000 kilometers without major repairs. However, like any complex mechanism, it requires regular attention and diagnostics. The main condition for longevity is timely replacement of oil and filters. The oil change interval is 10,000 kilometers, but in the conditions of Russia and the CIS countries it is recommended to reduce it to 7,000–8,000 kilometers.

Particular attention should be paid to the cooling system. VQ engines are prone to overheating if the thermostat or radiator is faulty. It is also worth checking the condition of the pipes and clamps, as rubber becomes dull over time and may leak. The crankcase ventilation system requires cleaning every 50,000 kilometers to avoid oil getting into the intake manifold and carbon deposits forming on the valves. This is especially true for engines with direct injection, where carbon deposits form more quickly.

Ignition coils and spark plugs are consumables that should be replaced every 60,000–80,000 kilometers. Misfires can damage the catalytic converter, which is very expensive to replace. It is also worth monitoring the condition of the timing belt and rollers, although their service life is stated by the manufacturer as 150,000 kilometers, it is better to change them in advance to avoid breakage. If the timing belt breaks on these engines, the valves meet the pistons, which leads to a major overhaul.

Frequent VQ35 engine problems

1. Oil leakage through the valve cover gasket (especially on older engines). 2. Knocking of hydraulic compensators during a cold start (often treated by replacing the oil with a higher quality one). 3. The throttle valve is clogged and needs to be cleaned. 4. Wear of the generator shaft bushings, causing knocking.

Owners often ask about the possibility of installing a turbocharger or chip tuning. While this is technically possible, it is often impractical for naturally aspirated VQ engines. The power gain will be negligible compared to the risks and costs, and reliability may be significantly reduced. It is better to focus on regular maintenance and the use of quality consumables, which will guarantee stable engine operation for many years.

Torque, Nm	330 - 336	336	325 - 340
Acceleration 0-100 km/h	8.0 sec	7.2 sec	7.4 sec

As can be seen from the table, despite the similar volume, the characteristics changed from generation to generation. The increase in power and torque was achieved through the introduction of new technologies such as phase shifters and direct injection. However, it is worth noting that an increase in power does not always mean a linear increase in fuel consumption, since modern engine management systems allow optimizing engine operation in various modes.

The choice of a specific modification depends on your priorities: if maximum power and dynamics are important to you, you should pay attention to the third generation models. If you are looking for a more budget option with proven reliability, then the first or second generation with the VQ35DE engine will be an excellent choice.
