THE SOPHISTICATED MUSCLE CAR

In their advertisements Infiniti likes to call the all-new M45 sport sedan the muscle car with brains, I see it as a new type of sedan with lots of muscle and sophistication.
Right now Infiniti is on a tear introducing several all-new vehicles and winning
awards along the way. The M45 is nicely positioned between the larger, more
expensive Q45 sedan and the smaller, all-new G35 sedan, which won Motor Trend
Magazines New Car of the Year award. For me the M45 is the
right size with great power and a long list of high performance features and
interior amenities with a price competitive with premium 6-cylinder vehicles.
The rear styling offers a simple yet sport form, with swept back C-pillar, tapered
rear and highly visible combination lamps with 2-wide, polished stainless steel
exhaust tips under the bumper. The looks are very clean, as if the M45 were
cast from a solid piece of metal. The stiff and rigid, high-strength steel unitized
frame features body panels formed from 2-sided galvanized steel sheet metal.
The muscle can be found under the hood with the standard aluminum alloy, dohc,
4.5liter V8 engine that produces a prodigious 340hp at 6,400rpm and 333lb.ft.
of torque at 4,000rpm. This powerplant is hooked up to a 5-speed electronically
controlled automatic OD transmission with a gated shifter and an easy, fun to
use manual shift mode. The front engine/rear-wheel drive setup gets the M45
going very quickly with 0-60mph acceleration in just 6.1sec. and covering the
1/4mi. in 14.4sec. at 98mph. Top speed is electronically governed to 155mph
but the M45 could go a lot faster.
Managing the handling of this powerful sport sedan is a sophisticated fully
independent suspension system featuring, up front, struts, coil springs, gas-charged
shocks and stabilizer bar. The rear features a multi-link setup with coil springs,
gas-charged shocks and stabilizer bar. The electrically controlled, vehicle
speed sensitive, power-assisted rack & pinion steering system is a prefect
match and responds quickly to your every input at speed. When going into curving
roads the crisp response is evident as you go deep and let the rear swing out
slightly, easing up on the throttle and quickly getting the rear back for straight-line
acceleration. The big18X7.5in. high-performance tires also respond with excellent
traction. The M45 gets through the 600ft. slalom at 61mph.
The power brakes are state-of-the-art steel discs, 11.4in. up front with dual-piston
calipers, while the rear discs measure 11.5in. clamped with a single piston
caliper. You benefit with ABS, electronic brake force distribution and brake
assist to quickly bring you to a safe and short stop. The M45 brakes from 60mph
to 0 in just 120ft. It could be even better with 13in. front rotors and 12in.
rear rotors.
While the M45 is a drivers car, Infiniti also designed the
interior for comfort and safety. The luxurious sport contoured front bucket
seats are finished with soft, Infiniti-exclusive leather seating surfaces. A
10-way power adjustable drivers and 4-way power passenger seat is standard
on every M45. You can also choose optional Climate Controlled Seats (CCS)
with heating and cooling to enhance comfort in all climate conditions. The interior
features a leather/wood, power tilting/telescoping steering wheel that feels
great in your hands, genuine Birds Eye Maple wood trim with smoke graphite
colored performance oriented four-dial instrument cluster. The M45s high
tech luxury amenities include an optional DVD-based navigation system, Intelligent
Cruise Control that maintains driver selected following distance and the state-of-the-art
Voice Recognition System from the Q45.
Other standard features include a 225watt Bose premium digital audio system
with 7-speakers, AM-FM stereo cassette player/6-CD changer, dual-zone electronic
temperature control, dual power-remote-controlled side mirrors that tilt down,
are heated and self-dimming on the drivers side, electro-chromic rearview
mirror with LED compass heading, rear console mounted air vents, Infiniti analog
clock, power-windows/door locks, a good amount of interior storage space, including
a very large trunk with center pass-thru, variable speed wipers/washers, theater
lighting, grab handles mounted above each door, full perimeter thick pile carpeting/floor
mats and rear fold-down center console with dual cup holders.
For safety, the M45 comes standard with dual stage front supplemental air bags,
front side-impact airbags, front and rear curtain side impact supplemental airbags
and active head restraints up front along with 3-point safety belts for all
seats with the front seats featuring pretensioners and load limiters. Passive
safety features include an energy absorbing steering column, front and rear
crush zones, hood buckling creases, and safety stops, body-side reinforcements,
and LATCH child seat tethers in the outboard rear seating positions.
With a base sticker price of just $42,300.00, the M45 is set apart from other
vehicles in the mid-luxury segment because the M45 is infused with lots of power
and performance with luxury features normally seen only in high-end flagship
models.
The all-new 2003 Infiniti M45 is a new type of performance sedan for the 21st.
century, a car with lots of brains and lots of brawn for under $45,000.00.
