The cornerstone of the Infiniti G35’s performance is its standard 3.5-liter DOHC 24-valve V6 engine. This engine, part of the acclaimed VQ engine series, produces 280 horsepower in models equipped with the automatic transmission and an even more potent 298 horsepower when paired with the 6-speed manual transmission (G35 Coupe 6MT). The engine boasts a suite of advanced technologies, including a continuously variable valve timing control system (CVTCS) for optimized efficiency and power delivery across the RPM range. A “noiseless” timing chain ensures refined operation, while the structurally reinforced aluminum engine block contributes to both durability and weight reduction. The electronically controlled “drive-by-wire” throttle system provides precise and immediate throttle response. Further enhancing its sophistication, the engine features a modular design, microfinished crank journals and cam lobes, and molybdenum-coated lightweight pistons, all contributing to its smooth operation and longevity.
Chassis, Suspension, and Handling Dynamics
For the 2006 model year, the Infiniti G35 coupe continues to utilize an advanced 4-wheel multi-link suspension system. This sophisticated design incorporates extensive use of aluminum-alloy components, significantly reducing unsprung weight. This reduction is crucial for enhancing suspension responsiveness and agility. Furthermore, the suspension integrates special “ripple control” shock absorber technology, striking a balance between responsive handling and a comfortable ride, making the Infiniti G35 equally adept at spirited driving and daily commutes.
The front suspension geometry is engineered to minimize unwanted alignment changes during cornering and over bumps, thanks to the use of two separate lower links and a long upper link. The rear suspension design strategically separates the shock absorbers and springs. By positioning the shock absorber inline with the wheel center, the design minimizes suspension friction and reduces axle wind-up during acceleration, contributing to improved handling and power delivery in the Infiniti G35.
For enthusiasts seeking an even sharper driving experience, the Sport-Tuned Suspension Package, standard on the G35 Coupe 6MT, offers a more aggressively tuned setup.

The 2006 Infiniti G35 coupe also benefits significantly from the adoption of the innovative FM (Front Mid-ship) platform. This platform strategically positions the engine behind the front axle, resulting in a near-ideal front-to-rear weight balance of 54:46. This optimized weight distribution takes into account weight transfer during dynamic maneuvers, such as corner entry and exit, contributing to more balanced and predictable handling. The FM platform also allows for the placement of large diameter wheels and tires closer to the vehicle’s corners, providing an extra measure of stability and enhanced grip for the Infiniti G35.
The G35 Coupe comes standard with 6-spoke, 17-inch cast aluminum wheels, fitted with P225/50VR17 tires at the front and wider P235/50VR17 tires at the rear, optimizing grip and handling balance. Optional 7-spoke, 18-inch titanium-finish wheels with high-performance tires are also available for those seeking enhanced aesthetics and performance.
For the G35 Coupe 6MT and models equipped with the Sport-Tuned Suspension Package, even more aggressive wheel and tire combinations are offered. These models feature 5-spoke, 19-inch forged aluminum-alloy wheels, renowned for their lightweight and strength, paired with P225/40YR19 front tires and wider P245/40YR19 rear tires. The Sport-Tuned Suspension Package also includes a standard Viscous Limited-Slip Differential (VSLD), further enhancing traction and cornering performance, especially in demanding driving situations for the Infiniti G35. Ensuring driver awareness of tire conditions, all G35 coupes are equipped with a standard Tire Pressure Monitor System (TPMS).
The braking system of the Infiniti G35 is equally performance-oriented, featuring 4-wheel ventilated disc brakes with large rotors for ample stopping power and heat dissipation. Standard Brake Assist (BA) provides additional braking force in emergency situations, while Electronic Brakeforce Distribution (EBD) optimizes braking balance between the front and rear wheels, enhancing stability and control during hard braking.
