The G35 is based on the Nissan FM platform shared with the Nissan 350Z sports car and Infiniti FX sport utility vehicle. The G35 was Motor Trend's Car of the Year for 2003 and has been well-received by both the media and customers as a viable alternative to more expensive luxury cars. The G35 was also nominated for the North American Car of the Year award that year and was on Car and Driver magazine's Ten Best list for 2003 and 2004.
Sporting the ubiquitous (and esteemed) VQ35DE engine, the Infiniti G35 uses a front-midship engine, rear-wheel drive layout (all-wheel drive is available for the G35x sedan) to achieve a 52/48 weight distribution (52% front/48% rear) . Both body styles are available with either a 5-speed automatic or 6-speed manual transmission, although the automatic is the only transmission available for the AWD sedan. The all-wheel drive model is designated the G35x and uses an Aisin-Warner intelligent AWD system that shifts power to the wheels with the most grip.
There are not many differences between the 2003 & 2004 G35 coupes. Both 03 & 04 6MT come standard with Brembo Brakes and the Performance Tire and Wheel Package. On the 2005 coupes, there were three new colors, 'Athens Blue', 'Lakeshore Slate' and 'Serengeti Sand', replacing 'Twilight Blue', Caribbean Blue, and 'Desert Platinum'. Also, Willow Cloth was removed and Stone interior was available. For the 2005 models, there were sportier gauges and better interior trim and knobs. Genuine Aluminum trim replaces "tinted" interior trim. Also, rosewood trim is available as a package on the 2005 models. The Brembo Brakes were removed for the 05 & 06 models. Instead, Sport-Tuned Suspension Package was standard on all 6MT models. The 2006 models received minor updates. On the exterior there were new headlights, taillights, spoiler, and front bumper. Bluetooth capability was added to the interior, for hands-free phone use. Rear active steering was also an option for the '06 5AT.
The G35's competitors include the Acura TL, Audi A4, BMW 3-Series, Cadillac CTS, Lexus IS, Mercedes-Benz C-Class, and Volvo S60.
