The Infiniti FX, Infiniti’s dramatic premium crossover SUV, enters the 2007 year with minimal changes after a major 2006 upgrade. The FX35 offers a new 18-inch wheel paint color with high luster finish and, for FX45, new standard power folding sideview mirrors. Interior refinements include a new seat belt reminder system and available iPod accessory.
The FX is available in both FX45 and FX35 designations. The all-wheel drive FX45 comes with a standard 320-horsepower 4.5-liter DOHC V8 (shared with the award-winning Infiniti M sedan) and includes 20-inch wheels and tires, leather-appointed seats and a sport-tuned 4-wheel independent suspension. The FX35 features a 275-horsepower 3.5-liter V6 and is available in all-wheel or rear-wheel drive. All FX models utilize a modified version of the advanced FM (Front Mid-ship) platform, enhanced for SUV duties.
The 2007 FX continues to serve as a showcase for Infiniti’s award-winning technology and engineering leadership with the available Lane Departure Warning (LDW) system, Intelligent Key and Intelligent Cruise Control (ICC) with Preview Braking.
Two engines are available in 2007, starting with the high-performance power of the 4.5-liter DOHC V8. This advanced powerplant, also used in the Infiniti M45 sedan, has been specially tuned for use in the FX45 and produces 320 horsepower and 335 lb-ft of torque.
The engine's advanced design includes titanium valves, modular cylinder heads, microfinished crankshaft, lightweight pistons, super-silent single stage cam drive chain and a hydraulically driven cooling fan to help optimize performance.
In addition, the VK45DE is outfitted with a variable length air induction system and Continuously Variable Valve Timing Control System (CVTCS) to enhance the engine’s power delivery and operation efficiency.
Also offered is a 3.5-liter DOHC 24-valve V6 engine with aluminum-alloy block and heads and electronically controlled “drive-by-wire” throttle system. Both the all-wheel drive and rear-wheel drive V6 engine-equipped versions are designated FX35 models.
The V6 has been tuned specifically for use in the FX35, with a horsepower rating of 275. Torque is rated at 268 lb-ft. A 5-speed automatic transmission with manual shift mode, designed for high torque capacity and light weight, is standard with both V8- and V6-equipped models. Activated by the driver, a special Snow-Mode function changes the throttle input algorithm in low-speed slippery road conditions for enhanced traction control.
