Infiniti G Sedan

From Infiniti press: The 2008 Infiniti G35 Sedan builds on the second-generation 2007 model’s myriad revisions, which included a next-generation 306-horsepower 3.5-liter V6; a striking new exterior defined by the sleek wave form hood, signature G-style taillights and raked A-pillars for an athletic stance; a crafted, Takumi-inspired interior environment; and the audiophile-quality Infiniti Studio on Wheels ä by Bose® .

For the 2008 model year, enhancements include a first-ever offering of a Sport Package for the G35x AWD model (in addition to being available on the G35 Journey Sport Package) and a new 18-inch Tire and Wheel Package for G35x AWD (late availability); revised Technology and Navigation Packages; available Infiniti iPod® Interface and Driver’s Audio Stage; and standard XM® Satellite Radio (requires XM® subscription, sold separately). There is also one new exterior color – Desert Platinum.

The soul of the G35 has always been its dynamic performance and at the heart of its advanced drivetrain has always been its award-winning VQ35 3.5-liter V6 engine and advanced FM (Front Mid-ship) platform. Both engine and platform were significantly enhanced for use with the second-generation G Sedan.

The VQ-series V6, which has been named one of the “Ten Best Engines” by Ward’s Auto World magazine for 13 consecutive years (now in its fourth generation) was thoroughly revised last year, with approximately 80% of major parts (except bolts, O-rings and clips) redesigned.

The block features ladder frame construction for greater rigidity and crank journal and pin diameters were increased. The block height was increased by 8.4 millimeters to reduce piston side force and the engine center is now 15 millimeters lower, which also contributes to the G’s improved dynamic performance.

Other new-generation engine enhancements included the addition of standard variable exhaust cam timing (eCVTCS), a higher redline (increased from 6,600 rpm to 7,600 rpm) and higher compression ratio (10.6:1 versus the previous 10.3:1), asymmetric piston skirts, twin knock sensors, improved coolant flow and new Iridium spark plugs.

The engine is rated 306 horsepower and 268 lb-ft of torque, a significant power improvement from the previous generation VQ, while also offering improvements in emissions and fuel economy.
