Nissan's luxury division redesigned its flagship sedan for 2002. Wider and taller than the 1997-2001 model, the new Q45 rode a longer wheelbase that yielded greater interior space. New styling includes 7-lens headlamps that were claimed to be the world's brightest. Infiniti sought to revive the Q45's performance roots by installing a 4.5-liter V8 that delivered 74 more horsepower than the prior generation's 4.1-liter. A five-speed automatic transmission, with manual shift gate took the place of the previous four-speed unit. Antilock four-wheel disc brakes with full power assist were standard, along with antiskid/traction control, 17-inch wheels, front and curtain side airbags, and leather/wood interior trim. An in-dash information screen served an available navigation system, and there was standard voice control for audio, climate, and navigation functions. A Sport Package option for the base Luxury model added 18-inch wheels, wider tires, and auto-adjusting shock absorbers with firmer sport mode. The Premium Package included a power-reclining rear seat, rear audio/climate controls, and a TV camera that displayed a view of the area behind the car when Reverse was selected. Radar-based Intelligent Cruise Control became available during the 2002 season. With the Q45, Infiniti competed against the BMW 540i, Lexus LS 430, and Mercedes-Benz E430/E500.
