The 2004 Infiniti G35 coupe represents a pivotal moment in the brand’s history, establishing a performance baseline that would define the line for years. For enthusiasts, the combination of a naturally aspirated V6 and a rear-wheel-drive layout delivers a driving experience that remains engaging today. Understanding the specific horsepower figures and the engineering context behind them provides clarity on why this model year holds such esteem.
Factory Specifications and Output
According to Infiniti’s official documentation and period road tests, the 2004 G35 coupe is equipped with a 3.5-liter VQ35DE V6 engine. This powerplant is rated at 280 horsepower at 6,000 rpm and 258 pound-feet of torque at 4,400 rpm. This specific output positioned the coupe as a compelling alternative to European sports sedans, offering a blend of smoothness and accessibility that was distinct in its class.
Performance Metrics and Real World Translation While the raw horsepower number is a key data point, the true performance of the 2004 model is best understood through its application. The power is transmitted through a five-speed automatic transmission with a manual shift mode, sending power to the rear wheels. This configuration enables a 0 to 60 mph time of approximately 6.0 seconds and a quarter-mile completion in the mid-14-second range, figures that were competitive for the era. The Engineering Behind the VQ35DE The VQ35DE engine is celebrated for its aluminum block and head, which contribute to a low curb weight of roughly 3,500 pounds for the coupe. Variable Valve Timing (VVT) on the intake camshaft is a critical technology, allowing for optimized valve overlap and efficiency across the rev range. This engineering not only produces reliable power but also aids in the driving dynamics that the G35 is praised for. Handling and Drivetrain Dynamics

Power is only effective if it reaches the ground with precision. The G35 coupe features a multilink rear suspension and a MacPherson strut front suspension, contributing to its balanced weight distribution. This setup, paired with the available ATTESA E-TS Pro four-wheel-drive system in certain trims, ensures that the 280 horsepower is delivered with confidence, particularly in less-than-ideal weather conditions.
Comparative Context in the Luxury Sport Segment
When placed alongside contemporaries like the BMW 325i and the Acura TL, the 2004 Infiniti G35 coupe holds its own. The BMW offered a more engaging manual transmission and sharper steering feel, while the Acura prioritized a more refined interior. The G35 carved its niche by providing a higher horsepower output than the base 325i and a more luxurious cabin than the TL, making it a popular choice for buyers seeking a middle ground.
Maintenance Considerations for Preserving Power
To maintain the original 280 horsepower output, diligent maintenance is essential. Key areas of focus include the timing chain, which is generally robust but should be inspected during major services, and the engine mounts, which can degrade over time and affect throttle response. Using high-quality synthetic oil and addressing vacuum leaks promptly will help ensure the V6 continues to perform as the factory intended.
Legacy and Collector Interest
Today, the 2004 model year is often viewed as the sweet spot for the first-generation G35 coupe. The combination of strong performance, daily usability, and evolving collector interest means that examples in good condition continue to appreciate. For the modern driver, owning a 2004 G35 is less about nostalgia and more about appreciating a well-executed piece of automotive history that defined a generation of sporty luxury cars.
