1985-1995 Nissan Skyline VII Coupe (R31) 2.6 R6 Turbo (220 Hp) 4WD

The Nissan Skyline VII Coupe (R31) 2.6 R6 Turbo (220 Hp) 4WD represents a significant, though often overlooked, chapter in the storied history of the Nissan Skyline. Produced from 1985 to 1995, the R31 generation marked a transition for the Skyline, embracing more advanced technology and a more refined driving experience. This specific variant, a two-door coupe powered by a 2.6-liter turbocharged inline-six engine and featuring a four-wheel-drive system, was exclusively sold in the Japanese domestic market and served as a crucial stepping stone towards the globally recognized performance of later Skyline models, particularly the R32 GT-R. It occupied a position as a sophisticated sports coupe, blending performance with a degree of luxury not previously seen in the Skyline lineage.

Powertrain & Engine Architecture

The heart of the R31 2.6 R6 Turbo 4WD is its 2.6-liter (2569 cc) inline-six cylinder gasoline engine. Nissan engine codes ABS and RB26DET identify this powerplant. This engine, mounted longitudinally in the front of the vehicle, utilized a multi-port fuel injection system and a turbocharger to achieve a respectable 220 horsepower at 6800 RPM. Peak torque was rated at 180.7 lb-ft (245 Nm) at 5200 RPM, providing a broad powerband suitable for both spirited driving and comfortable cruising. The engine’s inline-six configuration, a Nissan hallmark, is inherently balanced, contributing to smooth operation and reduced vibration.

The engine featured four valves per cylinder and a compression ratio of 10.5:1, optimizing both power and efficiency. The turbocharger, a Garrett unit, provided significant boost, enhancing the engine’s output without sacrificing drivability. Fuel delivery was managed by a sophisticated electronic fuel injection system, ensuring precise control over the air-fuel mixture. The automatic transmission used in this variant is a 5-speed unit, designed to handle the engine’s torque output and provide smooth, responsive shifts. While a manual transmission was available on other R31 models, the automatic was favored for its ease of use and suitability for the car’s more luxurious character.

Driving Characteristics

The R31 2.6 R6 Turbo 4WD offered a unique driving experience compared to other Skyline variants of the time. The combination of the turbocharged engine and the all-wheel-drive system resulted in strong acceleration and excellent traction, particularly on slippery surfaces. While the 5-speed automatic transmission wasn’t as engaging as a manual gearbox, it was well-tuned to complement the engine’s power delivery, providing smooth and predictable shifts. Compared to the naturally aspirated versions of the R31, the turbocharger provided a noticeable boost in performance, offering quicker acceleration and a higher top speed.

The all-wheel-drive system, a precursor to Nissan’s ATTESA E-TS system found in the R32 GT-R, distributed power to all four wheels, enhancing stability and cornering grip. This system, combined with the R31’s relatively long wheelbase, resulted in a planted and confident feel on the road. However, the R31’s weight (approximately 3263 lbs) did limit its overall agility compared to lighter, more focused sports cars. The gear ratios in the automatic transmission were optimized for a balance of acceleration and fuel economy, prioritizing smooth cruising over outright performance.

Equipment & Trim Levels

The Nissan Skyline VII Coupe (R31) 2.6 R6 Turbo 4WD was positioned as a premium trim level within the R31 lineup. Standard features included power windows, power locks, and air conditioning. The interior typically featured cloth upholstery, although leather options were available. The dashboard layout was functional and driver-focused, with clear instrumentation and easy-to-reach controls. An anti-lock braking system (ABS) was a notable standard feature, enhancing safety. Optional extras included a premium sound system, upgraded interior trim, and a sunroof.

The exterior styling of the 2.6 R6 Turbo 4WD was distinguished by its sporty coupe body style, alloy wheels, and subtle aerodynamic enhancements. The car’s overall design reflected the aesthetic trends of the mid-1980s, with a boxy silhouette and angular lines. The interior trim levels were generally well-appointed, offering a comfortable and refined driving environment. The focus was on providing a balance of performance and luxury, appealing to buyers who wanted a stylish and capable sports coupe.

Chassis & Braking

The R31 2.6 R6 Turbo 4WD utilized a MacPherson strut suspension system at the front and a semi-trailing arm suspension at the rear. This suspension setup provided a comfortable ride while maintaining reasonable handling characteristics. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering. The braking system consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the car’s weight and performance. Hydraulic power steering was standard, offering responsive and precise steering control.

The chassis of the R31 was designed to accommodate the all-wheel-drive system and the turbocharged engine. The car’s relatively long wheelbase contributed to a stable ride, while the all-wheel-drive system enhanced traction and handling. The suspension components were tuned to provide a balance of comfort and performance, making the R31 a capable and enjoyable car to drive in a variety of conditions. The braking system, while adequate, wasn’t as sophisticated as those found on some contemporary sports cars.

Market Reception & Comparison

The Nissan Skyline R31 2.6 R6 Turbo 4WD was well-received in the Japanese market, particularly among enthusiasts who appreciated its blend of performance, technology, and luxury. Critics praised the engine’s power and smoothness, as well as the all-wheel-drive system’s ability to enhance traction and handling. However, some reviewers noted that the car’s weight and automatic transmission limited its overall agility compared to other sports coupes. Compared to the naturally aspirated R31 models, the 2.6 R6 Turbo 4WD offered a significant performance advantage, but it also came with a higher price tag.

In terms of fuel economy, the R31 2.6 R6 Turbo 4WD was typical for a turbocharged performance car of its era, achieving around 11.8 mpg in the city and 21.4 mpg on the highway. Reliability was generally good, although the turbocharger and all-wheel-drive system required regular maintenance. Compared to rivals like the Toyota Supra and Mazda RX-7, the R31 offered a unique combination of features and performance, appealing to a different segment of the market.
