The AWD model of the G35 sedan is called the G35x in the United States and the Angelax elsewhere. Although the automatic transmission for the G35x is manufactured by Aisin-Warner, the AWD technology uses Nissan's proprietary ATTESA E-TS AWD system. The system will make the car 100% rear wheel drive when driving at a steady speed. When the driver uses the throttle to accelerate from a stop or constant speed, the AWD system can send up to 50% of torque to the front wheels. When the car's speed becomes steady again, the drivetrain will return torque to the rear wheels. The AWD system will also transfer torque to the front wheels if the system detects loss of traction. The process is made by the system in a matter of milliseconds. This technology was first used in the 1989 Nissan Skyline GT-R, and has since been used in subsequent Skylines, and other vehicles in Japan and overseas, including the Nissan Bluebird, and Nissan Stagea. There are few differences between the 2003 & 2004 G35 coupes. Both '03 & '04 six-speed manual models had the option of Brembo brakes and the Performance Tire and Wheel Package. On the 2005 coupes, three new colors, 'Athens Blue', 'Lakeshore Slate', and 'Serengeti Sand', replaced 'Twilight Blue', Caribbean Blue, and 'Desert Platinum' respectively; also, Willow Cloth interior was removed, and Stone became available.
G37 Convertible was introduced in June 2009 Media Release as a 2009 model on the V36 FM platform and is only from a design perspective based on the G Coupe.
The new G Convertible comes equipped with a standard 325-horsepower 3.7-liter V6, backed by a choice of a 7-speed automatic transmission with available magnesium paddle shifters or a responsive close-ratio 6-speed manual transmission – offering buyers the same high levels of performance as the G37 Sedan and G37 Coupe, along with the wide-open exhilaration of top-down driving.
Standard comfort features include dual-zone automatic climate control, a premium 11-speaker, 300 watt Bose stereo with in-dash 6 CD changer and 2GB hard drive, steering wheel mounted audio controls, premium leather seating surfaces, heated front bucket seats, heated power mirrors, 10-way power driver seat w/ lumbar adjustment, 8-way power passenger seat, individual driver memory system (drivers seat, side mirrors, and steering wheel positions), RearView back-up camera, UV reflective glass, and Infiniti's Intelligent Key system. The Intelligent Key design from the first generation FX now incorporates a Push Button Ignition system. With this system, the driver does not have to remove keys to drive the vehicle; a simple electronic fob carried on the driver allows the driver to lock/unlock and start the vehicle keyless.
The Infiniti FX was the first passenger vehicle to offer a lane departure warning system in the United States. Infiniti's version uses a camera that watches the lane markings to alert everyone in the car via an audible buzzer that the driver is drifting unintentionally.
