The Infiniti G35 gained its reputation for speed primarily due to its advanced VQ series engine, a robust chassis, and a design that prioritizes performance.
The Heart of the Beast: The VQ Engine
At the core of the Infiniti G35's performance lies its highly acclaimed 3.5-liter VQ series engine. This engine family is celebrated for its blend of power, reliability, and tunability, making it a favorite among enthusiasts.
Engineered for Power
The VQ engine's design incorporates several key features that contribute to its impressive output and responsiveness:
- All-aluminum construction: The engine block and heads are crafted from all-aluminum, significantly reducing the overall weight of the powertrain. This contributes to a better power-to-weight ratio, enhancing acceleration and agility.
- 3.5-liter displacement: This ample displacement provides a strong foundation for both torque and horsepower, ensuring exhilarating performance across the RPM range.
- Variable Valve Timing (VVT): Equipped with variable valve timing, the engine can optimize valve lift and duration across the RPM spectrum. This technology ensures efficient combustion and maximum power output, whether you're cruising or pushing the limits.
- Dual Overhead Camshafts (DOHC) with Four Valves per Cylinder: The engine features DOHC heads with four valves per cylinder. This sophisticated valvetrain design significantly enhances airflow into and out of the combustion chambers, allowing the engine to "breathe" more freely and generate greater power.
- Forged Connecting Rods: The inclusion of forged connecting rods is a testament to the engine's inherent strength and durability. These stronger internal components are capable of withstanding considerable stress, making the engine not only robust in stock form but also highly receptive to performance modifications.
These design choices mean that the ingredients for lots of horsepower are there from the factory, providing a solid foundation for performance.
Beyond the Engine: Performance-Oriented Design
While the VQ engine is a powerhouse, the G35's overall design further amplifies its speed and driving dynamics.
Power Delivery and Chassis
The G35 typically came with a rear-wheel-drive (RWD) configuration, a choice often preferred in sports cars for its balanced handling and direct power transfer. Some models were also available with intelligent all-wheel-drive (AWD), offering enhanced grip in various conditions. The chassis is stiff and well-tuned, providing a stable platform for high-speed maneuvers and cornering, effectively putting the engine's power to the pavement.
Modding Potential
One of the reasons for the G35's "fast" reputation is its immense modifiability. Its inherent robustness and ease of modification allow owners to unlock even greater potential. In fact, cooking up scary horsepower in the G35 is easy due to the engine's durable internals and aftermarket support for forced induction systems like turbochargers and superchargers, which can significantly boost output far beyond stock levels.
