The Infiniti FX-series (called the Infiniti QX70 from late 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. The FX has been described as having the profile of a "giant scarab" or a "Bionic cheetah". Its designers sought what they called a "cool fusion" – the blending of a substantial SUV lower body with the sleek, elegant upper body more reminiscent of a classic sports car or sports GT.〔(2006 Infiniti FX35- FX45 Vehicle Overview )〕 In addition, they sought to combine sports-car performance with SUV functionality. The FX is now in its second generation, since the 2009 model year FX35 and FX50. ==First generation (S50, 2003–2008)== 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.〔auto.howstuffworks.com/naias200121.htm〕〔http://www.motortrend.com/auto_shows/112_02as_2002_detroit_auto_show/viewall.html〕〔http://www.ultimatecarpage.com/cg/1188/Infiniti-FX45.html〕〔http://www.autointell.net/Events/Naias-2003/daily-reports/day-2/naias-2003-day-2-2.htm〕〔http://www.freshalloy.com/showthread.php/45811-2003-INFINITI-FX-SERIES-SPEECH-AT-NAIAS!〕 In 2003 for the 2004 model, changes were the addition of a standard eight-way power front passenger seat that replaced the previous four-way design, the availability of aluminum roof rails and chrome-plated 20-inch wheels. Also new were a dark silver metallic finish for the 20-inch wheels (non-chrome-plated), the addition of a standard HVAC filter for all models and the addition of a new Snow-Mode function.〔http://www.theautochannel.com/news/2003/10/27/171446.html〕〔http://infinitihelp.com/models/2005/fx/index.php〕 In September 2004 for the 2005 model year, the FX range received enhancements such as lane departure warning (LDW) system that helps alert drivers to an unintended movement of the vehicle out of a designated traffic lane. Infiniti's system monitored the lane markings to alert passengers via an audible buzzer that the driver is drifting unintentionally. The LDW system, which utilize a small camera, speed sensor, an indicator and an audible warning buzzer, was offered on models. The Infiniti FX was the first passenger vehicle to offer a lane departure warning system in the United States market. In addition to LDW, the 2005 Infiniti FX range was now equipped with standard roof-mounted curtain supplemental curtain air bags with rollover protection for front and rear outboard seat occupants. Other enhancements to the FX lineup included the addition of dark chrome grille, headlight and clear taillight accents to the FX45 (also available as part of the V6 Sport Package on FX35 models), a new key fob design for the Infiniti Intelligent Key system and two new exterior colors, Sapphire and Sheer Platinum. Interior changes included a new standard etched aluminum trim.〔 Total 2007 sales of the FX45 numbered 1,598 units, about a tenth of the FX35s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Infiniti FX」の詳細全文を読む スポンサード リンク
