"The flagship of Nissan's luxury brand is redesigned for a spring debut as a 2002 model. Overall length is unchanged from the 1997-2001 generation, but the new Q is wider and taller on a longer wheelbase for more interior room. New styling includes 7-lens headlamps claimed to be the world's brightest. Infiniti aims to return Q45 to its performance roots and gives it a new 4.5-liter V8 with 74 hp more than the prior 4.1. A 5-speed automatic transmission with manual shift feature supplants a 4-speed without. Also standard: ABS 4-wheel discs with brake assist, traction control/antiskid system, 17-inch wheels, front side airbags, curtain side airbags, and leather/wood interior trim. An in-dash information screen serves an available navigation system, and there's voice control for audio, climate and navigation functions.

To the base ""Luxury"" model, the Sport Package adds 18-inch wheels, an adjustable sport suspension, and other items. The Premium Package includes a power-reclining rear seat, rear audio and climate controls, and rearview TV camera that displays on the dashboard screen to help backing up. Radar-based ""smart"" cruise control designed to maintain safe following distance is planned for later in the year. "
