Created as a fusion of luxury, performance and utility, the stunning Infiniti FX is impossible to ignore, whether standing still or in its natural habitat – in motion. A “radical expression of sport and utility,” FX offers exceptional levels of performance, refinement and driving exhilaration.
For the 2010 model year, the second for the totally rethought second-generation FX, it is again available with a choice of a 390-horsepower 5.0-liter 32-valve DOHC V8 engine with VVEL or a 303-horsepower 3.5-liter 24-valve DOHC V6. Each engine is paired with a standard 7-speed automatic transmission featuring Adaptive Shift Control and Downshift Rev matching (DRM).
The 2010 FX is also offered with available Intelligent All-Wheel Drive (standard on FX50), double-wishbone front/multi-link rear suspension and large 4-wheel disc brakes, along with available Continuous Damping Control (CDC)® suspension system, Rear Active Steer and 21-inch Enkei super lightweight aluminum-alloy wheels.
Performance has always been the hallmark of the Infiniti FX – both acceleration and braking, along with tight, responsive handling. The Infiniti FX50 model features a standard 5.0-liter V8 engine design rated at 390 horsepower and 369 lb-ft of torque. One of the keys to the V8’s impressive performance is the adoption of Infiniti’s patented Variable Valve Event & Lift (VVEL) valve control technology, which was first introduced on the high-performance Infiniti G37 Coupe. The VVEL system continuously adjusts valve event and lift amounts, enabling higher fuel efficiency with higher torque and improved emissions over conventional variable valve designs. The VVEL intake camshafts, which feature continuously variable lift control teamed with a Continuously Variable Valve Timing Control System (CVTCS), allow for a 6,800 rpm redline.
Also offered is an advanced 3.5-liter DOHC 24-valve V6, available on FX35 models. The V6 engine features an aluminum block and heads and electronically controlled throttle system and has been tuned specifically for use in the FX35. The engine is rated at 303-horsepower at 6,800 rpm and 262 lb-ft of torque.
The advanced V6 design also features a symmetric twin ram air intake system that reduces airflow resistance, Continuously Variable Valve Timing Control System (CVTCS), a silent timing chain for quiet operation, microfinished crank journals and cam lobes, and Teflon-coated lightweight pistons, a dual exhaust system with equal length exhaust manifolds and low muffler exhaust pressure to help improve engine breathing.
Only one transmission is offered on the 2010 FX – a refined 7-speed transmission that offers both a wide ratio of coverage and a wide lock-up area, as well as a manual shift mode, Downshift Rev Matching and Adaptive Shift Control (ASC). The standard ASC system adapts the transmission’s shift timing, depending on driving style, ensuring more responsive performance. ASC can switch between several different programs – adjusting gear hold and downshifting, helping the FX feel more like a manual shift transmission when desired.
