Infiniti-FX

The nameplates FX35 and FX45 refer to the two available engines. The FX35 is available in two drivetrains, the RWD and the AWD, which are both fitted to a dual overhead cam 3.5-liter 24-valve V6 VQ35DE gasoline engine, with aluminum-alloy block and heads, electronically controlled throttle system, and low-friction molybdenum-coated pistons that makes use of the continuous variable valve timing which in part optimizes the opening of intake valves. This is also coupled with an electronically controlled super-wide ratio five-speed automatic with a manumatic shift mode that includes the option of sequentially selected manual gearshifts and downshift rev matching.
The FX45 incorporates a 4.5-liter (4,494 cc) 32-valve V8 DOHC VK45DE gasoline engine with four valves per cylinder, microfinished camshafts with aluminum-alloy block and heads, low-friction molybdenum-coated pistons, titanium intake and exhaust valves, modular cylinder heads, microfinished crankshaft, lightweight pistons, super-silent single stage cam drive chain, and a Continuously Variable Valve Timing Control System that optimizes opening of intake valves. Development began in 1999 under newly appointed CEO Carlos Ghosn's NRP. Design work was completed in rapid succession in early 2001, for late 2002 production. Designed in 2000 under the "Bionic Cheetah" theme, the 2001 Infiniti FX45 Concept was introduced at the NAIAS in January 2001 to publicly "test the waters" of a sports-crossover. From mid-2001, a new concept based on the production design was developed and completed in late 2001. Sketches were first released in late November 2001. The second-generation 2002 FX45 Concept was introduced in January 2002 at the NAIAS '02 as a thinly-veiled production FX(S50) and planned production was announced for early 2003. In January 2003, the 2003 FX45 made its debut at the 2003 NAIAS and went on sale January 24, 2003.

 The Infiniti QX70 (called the Infiniti FX from 2003 through 2013) is a mid-size luxury crossover SUV produced by the Nissan-owned Infiniti luxury vehicle brand since the 2003 model year. The FX replaced the QX4 as Infiniti's mid-size luxury-type SUV, although the QX4 was smaller than the FX. It was released at the same time as its competitors, the Porsche Cayenne and Volvo XC90. It shares the same FM platform as the rear-wheel drive Nissan 370Z, and it "made no claims of climbing mountains...Rather, its aggressive shape promised style and quick handling, whereas the similarly sized Nissan Murano is based on the same D platform as the front-wheel drive Nissan Altima. The FX and QX56, whose platform is shared with the Nissan Armada, are not sold in Japan.

 he FX series was updated for 2006 with new options and standard features. The updates included an exterior facelift with new grille, bumper, wheel design and three new exterior colors, and inside a revised center console with new color screen. Many features previously optional were made standard, including the 300-watt Bose audio system, RearView Monitor, 7-inch color display, Advanced Air Bag System (AABS), leather seating surfaces with heated front seats, ten-way power driver’s seat with power lumbar support and eight-way power passenger’s seat.
The FX45 featured additional upgrades, including new 20-inch wheels, leather-appointed seats, a revised sport-tuned four-wheel independent suspension with new dampers, a Bluetooth system, and the Premium Package became standard..

The redesigned 2009 Infiniti FX was officially unveiled at the Geneva Motor Show on March 4, 2008, and went on sale in June 2008. The V6 model is still called the FX35 with the VQ35HR V6, however the V8 model has been renamed FX50 in recognition of its 5-liter engine with the newly developed VK50VE.
The exterior retains some of the first generation's "Bionic Cheetah" look and "giant scarab" profile, while incorporating new styling cues. Some of the most distinct features of the new FX are the longer, sharklike sculpted headlights, a large trapezoidal grille filled with horizontal dark-chrome waves, and completely functional side air vents. The overall size and dimensions of the new model, both external and internal, remain similar to the previous model.
The interior was completely redesigned to bring the FX up to the level of luxury found inside of other Infiniti models like the G37 and EX35. Features include stitched leather seats, stained maple wood or piano black finishes, and matte-finish surfaces.
