(later dual) zone climate control, Bose audio system with eight speakers and in-dash single disc CD player, auto dimming rear view mirror, automatic light on and delay off timer, steering wheel-mounted cruise control and head unit controls. Also standard was a memory system for the driver's seat and steering wheel. Options included an integrated satellite navigation system, 6-disc CD autochanger and heated seats. Nearly all Infinitis before or since have used a two-digit number following a letter to indicate displacement; the second-generation Q was an exception (as was the Nissan Pathfinder clone QX4). Model Year Changes 1998 New front seastbelt pretensioners; mechanical odometer replaced with a liquid crystal display unit. 1999 New standard features included power rear-window sunshade, power trunklid pull-down, and high-intensity xenon gas headlights. Touring edition (Q45t) gained dual-mode electronically controlled shock absorbers. 2000 New active front head restraints; rear child-seat anchors; one-touch open/close operation for the standard moonroof and all power windows. A newly optional nav system with dashboard touch-screen replaced a simpler, non-video system. The 10th Anniversary Touring edition had machine-finish wheels, special badges and upholstery, wood/leather steering wheel, and bird’s-eye maple interior accents. New platinum-tip spark plugs. 2001 Body-color door handles, bird’s-eye maple interior trim, and a leather/simulated-wood steering wheel were the only changes for 2001. Third generation (F50; 2001–2006) Introduced as a concept at the 2000 New York Auto Show, the Q45 was completely redesigned for 2002 and was heavily based on the JDM Cima. This Q45 focused on performance again with a new 340 hp (253 kW) 4.5 L VK45DE V8 engine, HID headlights, and revised styling. The car featured a 5-speed automatic transmission with overdrive. Development began in 1996, with exterior designs under Mamori Aoki frozen in 1998 and patented in March 2000. It was the first Infiniti with laser autonomous cruise control system. 1129 Q45s were sold in the United States for 2005. The 3rd generation Q45 reviewed by Car and Driver, Edmunds and Consumer Guide, receiving relative positive reviews. The 2003 model received a revised security system, numerically higher final drive ratio (for better acceleration - decreased highway fuel economy), reprogrammed TCU, and a mid-year satellite radio option. The CD changer could load CDs directly at the dashboard head unit. Standard equipment included a leather interior, power sunroof, 8-way power front seats, remote keyless entry, rain-detecting wipers and side curtain airbags. Standard electronics include: CD, 8 speaker Bose audio system,
