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.
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 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.
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
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
