Nissan Skyline 4-door: A complete guide to the legendary Japanese sedan

Many car enthusiasts, hearing the name Nissan Skyline, immediately imagine a coupe with a turbocharged engine and all-wheel drive that has become an icon of motorsport. However, the history of this brand is inextricably linked with elegant and comfortable four-door sedans, which often remain in the shadow of their sporty counterparts. It was these models that ensured stable sales and formed the image of a premium Japanese car for a wide audience.

Four-door Nissan Skyline is a separate universe where technology meets practicality. From the classic models of the 1980s to the modern versions sold under the Infiniti brand in some countries, the sedan has always offered a unique combination of features. You need to understand the differences between the generations to appreciate this car's potential in a used car.

Historical evolution of the Skyline sedan

The history of four-door models dates back to the 60s, when Prince Motor Company (acquired by Nissan in 1966) began producing sedans aimed at taxi companies and the corporate sector. These cars were distinguished by their endurance and spacious interior, which was critical for the Japanese market at that time. Over time, the design became more aggressive and the technical equipment more complex.

A special place in history is occupied by the R30 and R31 generations, which became a bridge between classics and modernity. During this period, the first versions with turbocharging and advanced suspension systems for that time appeared. Four-wheel drive became available on some modifications, which allowed the sedan to feel confident on snowy roads.

With the transition to the R33 and R34 platform, the emphasis shifted to sportiness, even in the sedan version. Under the hood appeared the legendary in-line sixes, capable of developing enormous power. Although the coupe received more press attention, it was the sedans that were in steady demand due to their ease of entry and trunk space.

• R32 generation: Introduction of the ATTESA E-TS all-wheel drive system into the sedan.
• R33 generation: Improved aerodynamics and more spacious interior.
• R34 generation: The pinnacle of engineering before the brand split.

⚠️ Attention: When choosing an old Skyline sedan, be sure to check the condition of the body for hidden corrosion, especially in the arches and sills, as these models were often used in harsh climatic conditions.

Technical characteristics and motors

The heart of most four-door Nissan Skyline are the motors of the RB and VR series. The RB26DETT inline six-cylinder engines have become a legend, but in sedans, naturally aspirated versions RB20DE or RB25DE were more common, which provided a smooth ride and sufficient dynamics for the city. Engine reliability combined with high-quality assembly made these cars very attractive.

In later generations (V35 and V36), engineers switched to new VQ series motors. These are V-shaped “sixes” with a volume of 2.5 and 3.5 liters, which were distinguished by high speed and excellent elasticity. For lovers of drive, supercharged versions were offered, where turbines were installed as standard, and not as a result of tuning.

The transmission has also undergone significant changes. If early models had classic manual transmissions, modern sedans are equipped with complex torque converter automatic transmissions or CVTs (in some versions). Choice gearboxes directly affects the character of the car: manual transmission gives complete control, and automatic transmission provides comfort.

• RB20DE: Aspirated engine, ideal for city use.
• RB25DET: Turbocharged version with excellent low-end torque.
• VQ35DE: Modern V-twin engine with high power.

Features of the body and configuration

The design of the four-door Skyline has always strived for a balance between sporty aggression and business restraint. The body lines are often smoother compared to the coupe, but the car retains a dynamic silhouette. Interior in top trim levels it amazes with the amount of leather upholstery and wooden inserts.

Trims range from basic workhorses to luxury versions with names like 25GT or 350GT. In rich versions you can find a navigation system, climate control for several zones, heated seats and even air suspension. It is important to understand that the presence of such options significantly complicates repairs if they fail.

The luggage compartment of the sedan is traditionally spacious, which makes Nissan Skyline an excellent choice for family trips. It is accessed through the classic trunk lid, which can be opened from the passenger compartment or with the key. Some models have a trunk opening mechanism using a kick gesture, which is rare for Japanese cars of that period.

• GT: Sports trim with lowered suspension.
• L: Luxury version with an emphasis on comfort and silence.
• GT-R: Rare all-wheel drive versions of the sedan with a turbo engine.

Hidden information about the trunk

On some R33 and R34 models, the trunk features a hidden hatch to allow long items, such as skis, into the cabin, enhancing the sedan's versatility.

Safety systems and suspension

Japanese engineers have always paid special attention to passenger safety. Four-door Skylines offer front and side airbags, and later models come with curtain airbags. Brake system usually equipped with ventilated discs all around and anti-lock braking system (ABS) as standard.

The sedan's suspension is tuned differently than the coupe's. It is softer, which allows you to comfortably overcome road unevenness. At the same time, the presence of anti-roll bars and thoughtful geometry of the levers provide decent handling. System ATTESA E-TS on all-wheel drive versions, distributes torque depending on the traction of the wheels with the road.

To improve handling at high speeds, some models were equipped with an active steering system (HICAS), which could turn the rear wheels at a small angle. This improved low-speed maneuverability and highway stability. However, the complexity of this system requires careful maintenance.

⚠️ Attention: The HICAS system in older models often requires replacing the hydraulic tubes and flushing the system, as fluid leaks can lead to steering failure on the rear wheels.

Operation and Maintenance

Possession Nissan Skyline requires a responsible approach. These cars are often imported from Japan, where mileage may be underreported and service history hidden. You should definitely conduct a full engine and transmission inspection before purchasing. Pay special attention to the condition of the turbine if the car is equipped with supercharging.

Parts for older models can be difficult to find, especially original body parts. However, there is a huge demand for RB engines and transmissions, making them affordable. Regular maintenance should include changing the oil, filters and checking the timing belts, since a broken belt on these engines often leads to a major overhaul.

For modern versions (V36), the situation with spare parts is more stable, since they are unified with the Infiniti G35/G37. This simplifies the search for analogues and consumables. However, electronic control units and sensors can be expensive, so their functionality is critical to the vehicle's performance.

Важно: При покупке с аукциона всегда запрашивайте аукционный лист, где указаны реальный пробег и состояние кузова. Игнорирование этого документа может привести к покупке проблемного автомобиля.
