The Nissan Skyline XI (V35) 2.5 i V6 24V GT, produced from 2001 to 2006, represents a significant departure for the iconic Skyline lineage. This eleventh-generation Skyline, built on Nissan’s innovative FM (Front Midship) platform, transitioned the model from a performance-focused sports car to a more sophisticated, luxury-oriented executive sports sedan. While previous Skylines, particularly the R32-R34 generations, were renowned for their tuning potential and the legendary GT-R variants, the V35 aimed for broader market appeal, aligning with global premium trends and serving as the basis for the Infiniti G35 sold in North America and other regions. The 2.5 i V6 24V GT trim was a core offering in the Japanese Domestic Market (JDM), designed to balance performance, comfort, and driving dynamics for everyday use and spirited touring.
Powertrain & Engine Architecture
The heart of the Nissan Skyline XI (V35) 2.5 i V6 24V GT is the VQ25DD engine, a member of Nissan’s highly acclaimed VQ series. This 2.5-liter (2495 cc / 152.25 cubic inches) naturally aspirated V6 engine features a Double Overhead Camshaft (DOHC) valvetrain with four valves per cylinder. A key technological feature was its direct injection fuel system, which improved fuel delivery precision, combustion efficiency, and throttle response. The engine boasts a compression ratio of 11:1, optimized for use with premium gasoline. The VQ25DD is known for its smooth operation and relatively robust design.
Power is delivered to the rear wheels through a four-speed automatic transmission. This transmission, while seemingly modest by modern standards, was chosen to prioritize smooth shifting and comfortable cruising, aligning with the car’s intended character. The transmission’s gear ratios are geared towards relaxed highway driving, with a focus on fuel efficiency rather than aggressive acceleration. The automatic transmission features a conventional torque converter design, providing smooth engagement and minimizing harshness during shifts.
VQ25DD Engine Specifications
The VQ25DD engine produces 215 horsepower at 6400 rpm and 199.14 lb-ft (270 Nm) of torque at 4400 rpm. This output provides adequate performance for a vehicle of its class, offering a responsive driving experience without the extreme power of higher-performance Skyline variants. The engine’s torque curve is relatively flat, providing good mid-range pull for everyday driving situations. The engine utilizes a variable valve timing system (VVT) to optimize performance across the rev range.
Driving Characteristics
The Skyline V35 2.5 i V6 24V GT offers a refined and comfortable driving experience. Compared to the manual transmission versions or the higher-output 3.0L variants, the 2.5L automatic model prioritizes ease of use and smooth operation. The four-speed automatic transmission, while not offering the quickest shifts, provides seamless gear changes, contributing to a relaxed driving experience. Acceleration is adequate, with a 0-60 mph time estimated around 7.5-8.5 seconds, depending on testing conditions and vehicle weight. The car feels stable and planted at highway speeds, thanks to its FM platform and well-tuned suspension.
The automatic transmission’s gear ratios are optimized for fuel efficiency and comfortable cruising, resulting in a slightly less engaging driving experience compared to the manual transmission options. However, the VQ25DD engine’s smooth power delivery and pleasing exhaust note contribute to an enjoyable driving experience. The car’s rear-wheel-drive configuration provides a balanced feel and predictable handling characteristics.
Equipment & Trim Levels
The 2.5 i V6 24V GT trim level was positioned as a mid-range offering in the Skyline V35 lineup. Standard equipment included automatic climate control, a CD player with multiple speakers, power windows and locks, and alloy wheels. Interior upholstery typically consisted of cloth seats, although leather options were available. Safety features included Anti-lock Braking System (ABS) and dual front airbags. Optional extras included a sunroof, navigation system, and upgraded audio system. The dashboard layout was designed for ergonomics and ease of use, with a clear instrument cluster and logically placed controls.
Compared to the higher-spec 3.0L GT-8 models, the 2.5 i V6 24V GT offered a more accessible price point and a slightly more comfort-focused driving experience. It lacked some of the performance-enhancing features of the GT-8, such as the more powerful engine and sport-tuned suspension, but provided a well-equipped and refined package for everyday driving.
Chassis & Braking
The V35 Skyline utilizes Nissan’s FM (Front Midship) platform, which positions the engine behind the front axle line, resulting in a near 50/50 weight distribution. This contributes to improved handling balance and stability. The suspension consists of independent wishbone suspension at both the front and rear, providing a comfortable ride and competent handling. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The steering system is a hydraulic rack-and-pinion setup, offering precise and communicative feedback.
Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, enhancing braking performance and stability, particularly on slippery surfaces. The brake calipers are typically single-piston designs, providing adequate stopping power for the car’s weight and performance.
Market Reception & Comparison
The V35 Skyline 2.5 i V6 24V GT received mixed reviews from automotive critics. While praised for its refined engine, comfortable ride, and well-appointed interior, some critics lamented the departure from the Skyline’s traditional performance image. Compared to the 3.0L GT-8 variant, the 2.5L model offered a more affordable entry point into the Skyline range, but at the expense of outright performance. Fuel economy was rated at approximately 28.3 US mpg (8.3 l/100 km) on the combined cycle, which was competitive for a V6 sedan of its size and class.
Reliability was generally good, with the VQ25DD engine proving to be a durable and long-lasting unit. However, some owners reported issues with the automatic transmission, such as rough shifting or premature failure. Overall, the V35 Skyline 2.5 i V6 24V GT offered a compelling package for buyers seeking a comfortable, refined, and reliable sports sedan.
