2003 Infiniti Q45

The top-level sedan in Infiniti's luxury line-up, the 2003 Infiniti Q45 is the brand's flagship model. As such, it has Infiniti's best of everything, in all areas, handling, power, interior amenity, comfort, safety and class. The result is a vehicle with incredible speed and power, razor sharp handling, standard everything, state of the art safety technology, both passive and active, and limousine comfort and ride quality.

This year sees two dozen changes in a complete refreshed design. The changes range from technical enhancements like a higher numerical final drive gear ratio (for a better acceleration feel), to revised exterior styling, with grille and rear finisher changes and new exterior colors. Value has been added with heated seats and other previous big-ticket options adopted as standard equipment.

Available Models
Unlike the other Infiniti models, the 2003 Infiniti Q45 has two trim-levels to choose from, with Luxury and Premium versions. For a small amount extra, buyers can add the few items not included at the Luxury grade.

Interior Features
Interior luxuries abound on the 2003 Infiniti Q45. For example, it features "Sojourner" leather upholstery on heated front bucket seats (10-way power driver side and 8-way power passenger side), dual-zone automatic climate controls, power tilt/telescoping wood/leather-wrapped steering wheel with radio controls for the 225-watt Bose AM/FM/6CD auto-changer, a memory system (driver seat, mirrors, steering wheel), wood interior trim, and heated power automatic day/night side mirrors with signal lights.

The Premium edition gets some additional electronic and technological sophistication. Standard equipment at this level includes intelligent cruise control, DVD navigation system, rear view monitor, climate-controlled front seats, heated and power reclining rear seats, rear climate and radio controls, power rear sunshade, manual rear side sunshades and, to top it off, computer controlled and driver adjustable rear suspension. For when the ride is just not smooth enough.

Exterior Features
Three new exterior colors (eight total colors available) are offered for the new model year, Emerald Mist, Brilliant Silver and Golden Sand, to cover an exterior that continues to be distinctive, elegant and performance oriented. A large grille and prominent Infiniti badge sets the tone, while the car's high-class sculpted profile, raised rear deck and large taillights. 17 or 18-inch wheels add to the form and function.

Performance
An aluminum-alloy, double overhead-cam, 4.5-liter V8 engine, one shared with the M45, produces a whopping 340 hp at 6400 rpm and 333 lb-ft of torque at 4000. Titanium valves, microfinished crankshaft, lightweight pistons, single stage cam drive chain and a hydraulically driven cooling fan maximize performance and minimize noise. A 5-speed automatic transmission with manual shift mode controls this powerplant, in concert with a Continuously Variable Valve Timing Control System (CVTCS), achieving mileage ratings from the EPA of 17/23 mpg and the ability to do 0-60 mph in under 7 seconds.

The built-in performance and handling technology includes the best that Infinity has to offer. Standard Vehicle Dynamic Control (VDC), which helps improve vehicle stability during understeer, oversteer or adverse road conditions and an integral Traction Control System (TCS) combine with technologies like the laser-guided intelligent cruise control, which maintains a constant distance between you and the car in front.

Safety and Security
Safety technology is extensive and first class with dual-stage supplemental air bags with seat belt sensors that sense collision severity, seat belt usage and deploy accordingly. Side-impact air bags and side curtain supplemental air bags and advanced belt systems, including the child-seat restraint LATCH system, add to occupant safety.

4-wheel vented disc brakes with ABS, Brake Assist and Electronic Brake force Distribution come as standard equipment on the Q45.
