Sold with a Luxury nametag, the 2004 Infiniti Q45 STD sedan packs sporty performance and engine power into a high-end, roomy, luxury sedan. The 4.5-liter, 340-hp V8 delivers 333 ft-lbs of torque and gets an updated 5-speed shiftable automatic this year. Also new is a rearview camera, which was previously optional. This helpful safety feature joins 4-wheel disc and ABS brakes, traction and stability control, 17-inch run-flat tires, automatic headlights, xenon HID headlights, auto-dimming rearview and exterior mirrors, a tire monitor, and dual front, front-side, and side curtain airbags for both rows. Its solid safety ratings make it an attractive choice for families that want extra luxury without sacrificing security. Optional 18-inch tires are available.

Creature comforts in the 2004 Infiniti Q45 STD come in the form of full power features, a 10-way power driver's seat with memory settings, an 8-way power passenger seat, wheel-mounted cruise and audio controls for the 6-CD changer, leather upholstery, heated front and rear seats, remote entry, a garage-door opener, a trip computer, sunroof, power tilt and telescopic steering, and leather and real wood accents throughout the interior. Voice-activated controls for the dual-climate controls, Bose audio system, and cruise control allow drivers to keep their hands on the wheel.

For some, this may not be luxurious enough, so a special Premium package adds a navigation system with a 7-inch screen, rear climate and audio controls, satellite radio, powered reclining rear seats, heated and cooled front seats, and intelligent cruise control. A driver-adjustable electronic suspension is also optional. If you're looking for luxury with decent power, the 2004 Infiniti Q45 may be for you. If you need more than 13 cubic feet of trunk space, more distinctive styling, and less complicated dash controls, the comparable European models may be more up your alley.
