2003 Infiniti G35

Posted on by

Infiniti’s popular G35 Sedan, which continues to set monthly and yearly sales records, raised the bar in class in 2004 with the addition of an advanced all-wheel drive model, the G35x AWD. For 2005, G35 takes another major leap forward with a redesigned exterior, a refined interior featuring a new instrument panel and console area and increased horsepower and torque for the standard 3.5-liter DOHC V6 engine.

The most visible changes to the G35 Sedan for 2005 can be seen in the vehicle’s redesigned exterior, which features a new hood and trunk, new front and rear bumpers, body-colored side sills, revised headlight lens and new dual circle taillights. Also featured are new 7-spoke 17-inch aluminum-alloy wheels.

FM Platform

The 2005 G35 continues to utilize the racing technology-inspired FM (Front Mid-ship) platform, which mounts the engine behind the front axle in the “front mid-ship” position. The positioning of the engine is a key to the G35’s high level of driving performance, providing a nearly optimized 54:46 (55:45 G35x) percent front-to-rear-weight balance. This layout also features a long wheelbase (112.2 inches) and short front and rear overhangs, providing a large interior for its highly manageable overall length (186.5 inches) and excellent interior space utilization. A wide front and rear track adds to the G35’s overall handling stability and further enhances interior and trunk volume.

The FM platform design also places a strong emphasis on aerodynamics. The Infiniti G35 has a coefficient of drag measurement of just 0.27 (0.26 with optional rear spoiler) for reduced wind noise and optimized fuel economy. The design also emphasizes the control of airflow under the body. The extensive use of diffusers and deflectors helps the G35 achieve zero front lift (0.0 clf), reducing drag and noise and contributing to vehicle stability. With the optional rear spoiler, zero rear lift is also achieved.

Interior

For 2005, the G35’s interior offers a new, even higher quality look and feel, along with a redesigned instrument panel and console area. Materials and textures have been refined to provide a richer impression and the use of real aluminum and new wood-tone trim provides a degree of authenticity to the interior. Available wood accents (Wood Trim Package) have been revised from Bird’s Eye maple to a straight-grained Rosewood and the application of wood trim in the interior has been expanded. A new Stone (gray) and Wheat (beige) interior colors join the previously available Graphite (black) to allow more choice for customers. Every 2005 G35 comes with standard leather-appointed seating.

Engine

Since its introduction, the G35 has been noted for its outstanding balance of acceleration and handling. The heart of G35’s performance is its standard 3.5-liter DOHC 24-valve V6, derived from the VQ engine series.

For 2005, several modifications have been made including a new electronic exhaust valve timing, improved cooling and air flow and strengthening of several components, resulting in an increase of horsepower and torque to 280 horsepower (from 260 hp) and 270 lb-ft of torque (from 260 lb-ft) for models equipped with the advanced 5-speed electronically controlled automatic transmission with manual shift mode.

The 2005 G35 6MT model with close-ratio 6-speed manual transmission receives an additional horsepower increase, bringing it to 298 horsepower (torque remains at 260 lb-ft).

The VQ engine design includes a long list of advanced systems, including a continuously variable valve timing control system, a “noiseless” timing chain for quiet operation, a structurally reinforced aluminum engine block and an electronically controlled “drive-by-wire” throttle system. It also features a modular engine design, microfinished crank journals and cam lobes, and molybdenum coated lightweight pistons.

All-Wheel Drive System

Along with its advanced engine design, the G35 is also offered with a state-of-the-art “intelligent” all-wheel drive system. Introduced in December 2003, the G35x AWD model features Infiniti’s ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system, which is also utilized on the Infiniti FX45 and FX35 AWD premium crossover SUVs.

The system utilizes an active torque distribution management system with an active center differential designed for smooth starts, better fuel economy and better traction and maneuverability on snowy roads than conventional all-wheel drive systems and minimal compromise of rear-wheel drive performance characteristics on dry roads.

Suspension

Both front and rear suspension designs utilize aluminum components to reduce unstrung weight and incorporate “ripple control” shock absorbers with damping control lips for suppressing high-frequency, micro-amplitude vibrations. As a result, tiny ripples in the road surface are absorbed to deliver a smooth, comfortable ride.

Wheels

The 2005 G35 features standard 17-inch aluminum-alloy wheels with P215/55R17 tires on automatic transmission models and 18-inch aluminum-alloy wheels and P235/45R18 tires on the 6-speed manual transmission model.

The 2005 Infiniti G35 is available in three models – G35, G35x AWD and G35 6MT. The G35 and G35x AWD come with standard 5-speed automatic transmission and manual shift mode with downshift rev matching and 17-inch wheels and tires. The G35 6MT model features a close-ratio 6-speed manual, 18-inch wheels and tires, Viscous Limited-Slip Differential, sport-tuned suspension and higher horsepower engine tuning.
