2003 Infiniti M45- Price Quote

Visit Infiniti for more information on the Infiniti M45.

The 2003 Infinity M45 is a full-size luxury sedan with performance, both handling and power, design priorities. However, as a luxury sedan, it also has the high content of interior fittings and features that one would expect from Nissan's upscale division.

The 2003 Infiniti M45 is designed to fill the price-gap between the flagship Q45, with which it shares many performance components, and the lower level G35 sport sedan. However, that is not to say that this is a G35 with a 4.5-liter engine. The styling and dimensions of the rear-wheel drive V8 M45 are all its own.

Available Models
Like the other Infiniti models, the 2003 Infiniti M45 has one trim level and model. However, it features a very high level of standard offerings, one more characteristic of the amenity level found in more upscale cars. This standard is then complemented by useful stand alone options as well as several major equipment packages to add specific desired details for those who want them.

Interior Features
Sport contoured 10- (driver) and 4-way powered front bucket seats with Sojourner leather upholstery start off the M45 interior styling list. Optional Climate Controlled Seats (CCS') are available, offering both heating and cooling functions which significantly enhance driver and passenger comfort.

Bird's Eye Maple wood trim with a smoke graphite color add more styling touches while function is enhanced by the performance-oriented four-dial instrument cluster, complete with amber lighting that silhouettes the gauges. Also present is a 225-watt Bose premium audio system with an AM/FM tuner, an in-dash 6-disc CD autochanger and 7-speakers. Steering wheel audio controls, vehicle-speed-sensitive volume control and Radio Data System (RDS) all add function and convenience.

Optional add-ons like the M45's high tech DVD-based navigation system, Intelligent Cruise Control system that maintains driver-selected following distances and the state-of-the-art Infiniti Voice Recognition System are all available individually or as parts of major packages.

Exterior Features
The M45's exterior is very distinctive. Radiating dynamism and sport performance, the car has a go-fast look, one enhanced by an aggressive front grille, with wide black chrome horizontal bars that flow into the sporty, high-intensity discharge (HID) xenon headlights design.

A long 110.2-inch wheelbase and a dynamic wedge shape running from the front to the rear combines with swept back C-pillar, tapered rear appearance and highly visible combination lamps. Body-colored side molding, chrome door handles and aluminum 8-spoke wheels add notable touches.

The aluminum-alloy, double overhead-cam, 4.5-liter V8 engine on the Infinity produces a whopping 340 hp at 6400 rpm and 333 lb-ft of torque at 4000. A standard 5-speed automatic transmission with manual shift mode controls this powerplant, achieving mileage ratings from the EPA of 17/23 mpg. A bit of a guzzler but it does get to 60mph in under 7 seconds.

The M45's aggressive handling, outstanding stability and responsive steering are enhanced by standard Vehicle Dynamic Control (VDC), which helps improve vehicle stability during understeer, oversteer or adverse road conditions and an integral Traction Control System (TCS). An independent strut suspension with coil springs in the front and an independent multi-link suspension in the rear provide the stable, smooth ride. Standard 18-inch wheels and 235/45WR18 high performance tires add value and capability.

Safety and Security
4-wheel vented disc brakes with ABS, Brake Assist and Electronic Brake force Distribution all come as standard equipment on the M45 to comprise the active safety technology. Passive safety features include dual front and front side airbags, advanced belt systems and the child-seat restraint LATCH system.
