1985-1995 Nissan Skyline VII Coupe (R31) 2.0 i R6 24V (155 Hp)

The Nissan Skyline VII Coupe (R31) represents a pivotal, albeit often overlooked, chapter in the illustrious history of the Nissan Skyline. Produced from 1985 to 1995, the R31 generation marked a significant departure from its predecessors, embracing a more angular, squared-off aesthetic that was characteristic of the mid-1980s. While not as universally celebrated as the legendary R32, R33, or R34 generations that would follow, the R31 laid crucial groundwork, introducing advanced technologies and powertrain architectures that would become hallmarks of future Skylines. This particular variant, the 2.0 i R6 24V (155 Hp) Coupe, was a core offering in its primary market, Japan, where the Skyline nameplate held immense prestige as a performance and luxury icon. Never officially imported to the United States, the R31 remains a fascinating piece of JDM (Japanese Domestic Market) history, appreciated by enthusiasts for its unique blend of classic 1980s styling and the nascent stages of Nissan’s high-performance engineering.

Engine and Performance: The Heart of the 2.0 i R6 24V

At the core of the Nissan Skyline VII Coupe (R31) 2.0 i R6 24V (155 Hp) was a sophisticated 2.0-liter (1998 cm3 or 121.93 cubic inches) naturally aspirated inline-six engine. This powerplant, part of Nissan’s renowned RB-series family, featured a Double Overhead Camshaft (DOHC) valvetrain with 24 valves (four per cylinder), a cutting-edge design for its era that promised improved breathing and higher-revving capabilities. It delivered a respectable 155 horsepower at a peaky 6400 rpm, showcasing its sporting intent. Torque output stood at 137.19 pound-feet (186 Nm) at 4400 rpm, providing a strong mid-range pull for spirited driving.

The engine’s front, longitudinal layout, combined with a traditional rear-wheel-drive architecture, ensured a balanced chassis and engaging driving dynamics—a characteristic that has defined the Skyline lineage. Power was channeled through a precise 5-speed manual transmission, offering drivers direct control over the engine’s output. This setup allowed the R31 Coupe to achieve a top speed of 142.92 miles per hour (230 km/h), a commendable figure for a 2.0-liter car of its time.

Despite its performance aspirations, the 2.0-liter inline-six also offered reasonable, if not class-leading, fuel economy for its era. Urban driving consumed approximately 13.1 US miles per gallon, while extra-urban conditions saw this improve to around 23.5 US miles per gallon. With a 15.85 US gallon fuel tank, the R31 offered a decent cruising range, making it suitable for both daily commutes and longer journeys across Japan’s highways.

Positioning within the R31 Lineup

The 2.0 i R6 24V variant occupied a middle ground within the R31 Skyline Coupe range. It was positioned above the base 1.8-liter models, offering a significant performance upgrade, but below the more potent 2.8-liter inline-six and turbocharged variants. This made it an attractive option for buyers seeking a balance between performance, fuel efficiency, and affordability. It targeted a demographic of young professionals and enthusiasts who desired a stylish and capable coupe without the higher price tag of the flagship models.

Design and Features: An Icon of 80s Aesthetics

The Nissan Skyline VII Coupe (R31) embraced the design language prevalent in the mid-to-late 1980s, characterized by its sharp lines, angular bodywork, and a distinctive “boxy” silhouette. This two-door coupe body style accommodated five occupants, blending practicality with a sporty demeanor. Its dimensions—178.35 inches in length, 63.58 inches in width, and 52.17 inches in height, with a 102.95-inch wheelbase—gave it a substantial road presence without being overly cumbersome. The front and rear tracks, both measuring 57.48 inches, contributed to its stable stance.

Key features for the R31 generation, especially for its time, included advancements in braking and steering. The car was equipped with ventilated disc brakes at the front and solid disc brakes at the rear, providing robust stopping power. Crucially, it also featured an Anti-lock Braking System (ABS), a significant safety enhancement for the mid-1980s that improved control during emergency braking. Hydraulic power steering made maneuvering the 3240.8-pound (1470 kg) coupe effortless, enhancing the driving experience. The 205/55 HR16 tires provided a good balance of grip and ride comfort, fitting for a grand tourer with sporting ambitions.

Inside, the R31 offered a functional yet driver-focused cockpit, typical of Japanese cars of the era. While lacking the digital wizardry of some contemporary European rivals, it provided all essential controls within easy reach. The emphasis was on reliability and a straightforward, engaging driving experience, a philosophy that resonated deeply with the Japanese market.

Trim Levels and Standard Equipment

The 2.0 i R6 24V Coupe was typically offered in a few different trim levels, varying slightly in terms of interior appointments and optional extras. Standard equipment generally included power windows, central locking, and an AM/FM radio. Higher trim levels might add features like upgraded upholstery, a sunroof, and a more sophisticated sound system. The interior typically featured cloth upholstery, with options for leather available on some models. The dashboard layout was functional and straightforward, with clearly labeled controls and a comprehensive instrument cluster.

Chassis & Braking

The R31 Skyline utilized a traditional body-on-frame construction, providing a robust and durable chassis. The suspension system consisted of independent suspension at all four corners, although the specific design varied depending on the trim level. The 2.0 i R6 24V model typically featured a MacPherson strut front suspension and a multi-link rear suspension. This setup provided a good balance of ride comfort and handling performance. The braking system, as mentioned previously, consisted of ventilated disc brakes at the front and solid disc brakes at the rear, with ABS available as an option. The braking performance was adequate for the car’s weight and power, providing confident stopping power in most driving conditions.

Market Reception & Comparison

Critics generally viewed the 2.0 i R6 24V Skyline Coupe as a competent and well-rounded performer. It was praised for its smooth and responsive engine, its engaging driving dynamics, and its comfortable interior. However, some critics noted that it lacked the outright performance of the higher-trim models and that its styling was somewhat conservative compared to some of its rivals. In terms of fuel economy, the 2.0 i R6 24V offered a reasonable compromise between performance and efficiency, achieving around 18-23 mpg in real-world driving. Reliability was generally good, although like any car of its age, it required regular maintenance to prevent issues. Compared to the 2.8-liter inline-six models, the 2.0 i R6 24V offered better fuel economy and lower running costs, but at the expense of performance. Compared to the turbocharged variants, it was significantly less powerful but also more reliable and easier to maintain.

Legacy

The Nissan Skyline VII Coupe (R31) holds a unique position in the Skyline hierarchy. It was produced during a period of intense technological development in the Japanese automotive industry, and while it might not possess the immediate cult status of its successor, the R32 GT-R, it was a crucial evolutionary step. The R31 introduced several innovations that would become foundational for future Skylines, most notably the advanced RB-series engines, which would power all subsequent GT-R models up to the R34. It also pioneered Nissan’s HICAS (High Capacity Actively Controlled Steering) four-wheel steering system in some higher-trim variants.

In the used car market today, the R31 Skyline is gaining popularity among collectors and enthusiasts. Well-maintained examples are becoming increasingly rare and valuable, particularly those with low mileage and original features. The 2.0 i R6 24V variant, while not the most sought-after trim level, offers a more affordable entry point into the world of vintage Skylines. Its relative simplicity and reliability make it a practical choice for those who want to experience the Skyline legacy without the higher costs associated with the more powerful and complex models. The RB20DE engine, while not as renowned as the RB26DETT, is known for its durability and ease of maintenance, making it a relatively trouble-free powerplant for classic car ownership.
