VQ35HR engine produces 290 horsepower, which makes the car incredibly sharp even in quiet driving mode. When choosing a used vehicle, you must carefully evaluate the condition of the transmission and cooling system.
This article will examine in detail all aspects of operation, including maintenance features and real fuel consumption indicators. You will learn the difference between rear-wheel drive and all-wheel drive and how to choose the right spare parts for a long vehicle life.
Engine and powertrain: The heart of the Nissan Fuga
The legendary naturally aspirated petrol engine is installed under the hood of the model. VQ35HR volume 3498 cubic centimeters. This unit belongs to the VQ family, which has been repeatedly recognized as the world's best engine in its class. The designers introduced a CVTCS variable valve timing system on both camshafts, which made it possible to achieve high power at high speeds.
Maximum power is 290 hp. at 6400 rpm, and peak torque reaches 363 Nm already at 4800 rpm. This characteristic ensures confident acceleration to 100 km/h in just 6.5–6.9 seconds, depending on the type of transmission. The engine is mated to a Jatco JF701R 7-speed automatic transmission.
- ✅ Power: 290 hp — excellent dynamics for a heavy sedan.
- ✅ Torque: 363 Nm provides excellent traction from the bottom.
- ✅ Fuel system: distributed fuel injection for stable operation.
A special feature of this engine is the absence of hydraulic compensators in the valve mechanism. This means that the owner will have to periodically adjust the valve clearances, otherwise, with a mileage of over 100,000 km, a characteristic knocking sound may appear. The adjustment procedure is complex and requires removal of the camshafts, which increases maintenance costs.
⚠️ Attention: Use only high-quality motor oil with a viscosity of 5W-30 or 5W-40, since the VTC (phase control) system is extremely sensitive to the quality of the lubricant. If you use low-quality oil, the timing chain or phase regulator may rattle, which will lead to expensive repairs.
It is important to note that the cooling system is made according to a complex design with two circuits: for the cylinder block and for the cylinder head. This ensures quick warm-up and stable temperatures under high loads. However, if you are planning long trips in a hot climate, keep an eye on the condition of the radiators, as they can become clogged with lint and dirt.
Transmission and drive: Dynamics and handling
Depending on the configuration, Nissan Fuga The 3.5 can be equipped with classic rear-wheel drive or all-wheel drive ATTESA E-TS. Rear-wheel drive versions have better weight distribution and a more sporty character, allowing the driver to enjoy drifts if desired. All-wheel drive automatically distributes torque between the axles depending on road grip.
Automatic transmission Jatco has seven stages, which allows the engine to operate in the optimal speed range both during acceleration and at cruising speed. Shifts occur almost imperceptibly, creating the feeling of a continuously variable transmission. However, with an aggressive driving style, slight jerking may occur when shifting from 1st to 2nd gear.
- ⚙️ Rear wheel drive: ideal for dry asphalt and drive enthusiasts.
- ⚙️ Four-wheel drive: necessary for winter conditions and bad roads.
- ⚙️ Operating modes: You can switch between Eco and Sport mode.
In Sport mode, the transmission holds the revs higher, providing instant response to the gas pedal. For those who prefer a sedate ride, Eco mode limits throttle harshness. Switching is carried out using the steering wheel paddles or the gearbox selector.
- Rear (RWD)
- Full (4WD)
- It doesn't matter, the main thing is the engine
- I'm looking for front wheel drive only.
All-wheel drive system ATTESA E-TS works on the basis of a clutch that can be locked if necessary. In normal mode, 99% of the torque is transmitted to the rear wheels, which maintains maneuverability. When the rear wheels slip, the torque is automatically redistributed forward, ensuring stability on slippery surfaces.
Suspension and steering
Comfort Nissan Fuga is provided by a complex multi-link suspension on all wheels. Front suspension type Double Wishbone provides excellent control precision, and the rear multi-link design guarantees a smooth ride even on uneven surfaces. The shock absorbers are tuned to smooth out small vibrations while maintaining rigidity in corners.
The steering is equipped with a variable force system, which depends on the speed of the vehicle. At low speeds the steering is light, making parking easier, but on the highway it becomes heavier, increasing stability. The power steering operates smoothly and does not create unnecessary noise.
⚠️ Attention: When buying a car, be sure to check the condition of the silent blocks of the levers. After a mileage of more than 100,000 km, they often require replacement, which leads to knocking in the suspension and misalignment of the wheels.
A special feature of the suspension is the use of anti-roll bars both front and rear. This helps reduce body roll when cornering. For fans of sporty driving, there is an optional adaptive suspension that changes the stiffness of the shock absorbers depending on the selected driving mode.
- 🛠️ Front suspension: independent, double wishbone.
- 🛠️ Rear suspension: independent, multi-link.
- 🛠️ Steering: rack and pinion with electric hydraulic booster.
To replace suspension elements, it is recommended to use original spare parts or high-quality analogues from leading manufacturers. Using cheap parts can lead to rapid wear and poor handling. Regular suspension diagnostics should be carried out every 15,000 km.
What is adaptive suspension?
The Nissan Fuga's adaptive suspension (optional) uses sensors that read road conditions and driving style, automatically changing the stiffness of the shock absorbers. This allows you to adapt the car for both comfortable city driving and dynamic highway driving.
