ON THE TRACK OR STREET, MONTE CARLO AIMS FOR VICTORY
LANE
From the number of checkered flags Monte Carlo has taken at NASCAR events,
one would be right in thinking that generations of Monte Carlo designs were
penned with winning in mind. The latest version drives into 2005 with subtle
changes to its successful formula.
Model lineup
For the 2005 model year, Chevrolet realigned the midsize Monte Carlo models
to include the LS, LT and Supercharged SS. Each of these Monte Carlos features
its own torque-rich V-6 engine that sends power to the front wheels via a
Hydra-Matic four-speed automatic transmission. The suspension is fully
independent, the steering is rack-and-pinion, and disc brakes are found at all
four corners.
New for 2005
OnStar becomes a significant new standard feature for 2005. OnStar-equipped
Monte Carlo models feature new sixth-generation hardware with digital and
analog coverage. OnStar’s Gen 6 hardware also includes upgraded hands-free
voice recognition capabilities including more intuitive continuous digit
dialing and improved voice recognition accuracy. OnStar is the leading
provider of in-vehicle safety, security and information services in the United
States and Canada. Using the GPS satellite network and wireless technology,
OnStar features core safety services and OnStar Personal Calling that allows
drivers to make and receive hands-free, voice-activated phone calls using a
powerful three-watt digital/analog system and external antenna for greater
reception.
The OnStar one-year Safe and Sound Service, and the hardware to use it, is
now standard in every Monte Carlo. The provided services include automatic
notification of air bag deployment, emergency services, roadside assistance,
stolen vehicle tracking, AccidentAssist, remote door unlock, remote
diagnostics, online concierge and remote activation of the vehicle's horn and
lights. Owners can also opt for other available OnStar services, including
making and receiving voice-activated, hands-free phone calls with Personal
Calling and getting location-based traffic and weather reports with Virtual
Advisor.
To help prevent the cluttered look of multiple antennae sprouting from the
rear deck, the traditional whip-style OnStar antenna has been replaced with a
clean, new roof-top design. When buyers order XM Satellite Radio, its antenna
is integrated into the OnStar unit for a clean exterior appearance.
Also for 2005, Chevrolet discontinued the non-supercharged SS model and
replaced it with the LT model. In keeping with ever-changing customer
preferences, three new colors have been added: Laser Blue Metallic, Sport Red
Metallic and Silverstone Metallic. Also, for the first time, the available
17-inch diamond-cut cast aluminum wheels can be had with a chrome finish on
the Supercharged SS model.
Monte Carlo power
This Chevrolet features a trio of V-6 engines that produce the kind of
torquey power drivers love. Each Monte Carlo model has its own powertrain, and
each matches that specific model's character.
The value-oriented Monte Carlo LS features the 3400 V-6. The 180 horsepower
(134 kw) 3400 V-6 features an overhead valve (OHV) head design, aluminum heads
and a cast iron block. This combination is ideal for torque production (205
lb.-ft./278 Nm), durability and economical operation – the Monte Carlo LS is
noted for its best-in-class fuel economy among V-6 competitors. The LS's
Hydra-Matic 4T65-E 4-speed automatic transmission features a tall 2.86:1 final
drive ratio – a significant contributor to the powertrain's efficiency.
The Monte Carlo LT uses the refined 200 horsepower (149 kw) 3800 Series II
V-6. This engine often surprises drivers with its power, smoothness and
quietness. Technically speaking, 90 percent of the engine's peak 225 lb.-ft.
of torque (305 Nm) is available at only 1000 rpm, just off idle. Years of
detail work have earned this OHV engine many national and international
awards, as well as a solid reputation within the engineering community. In the
LT, the Hydra-Matic uses a shorter final drive ratio of 3.29:1 for improved
acceleration.
The Monte Carlo Supercharged SS sports its namesake version of the boosted
3800 Series II Supercharged V-6.This award-winning engine boasts a torque
curve that is consistently high over a broad operating range, providing
instant, off-the-line acceleration and ample power for highway merging and
passing. The 3.8L supercharged (SC) engine generates 240 horsepower (179 kw)
at 5200 rpm, and an impressive 280 lb.-ft. (380 Nm) of torque at 3600 rpm.
Boost levels of up to 8 pounds can be monitored via the boost gauge integrated
into the instrument cluster.
The 3800 SC features a compact, 90-cubic-inch Roots-type supercharger. This
engine has been improved over the years by refining multiple individual
components and the controlling software in the powertrain control module. As a
result, the engine delivers power in a smooth, linear fashion by adding boost
at predetermined points along the power curve. This performance is further
supported by the 3800 SC's outstanding record for durability.
In the Monte Carlo Supercharged SS, the 3800 SC is matched to a heavy-duty
version of the Hydra-Matic 4T65-E four-speed electronically controlled
automatic transmission. The final drive ratio of this transmission is 2.93:1.
Chassis and suspension
Monte Carlo's body structure provides the foundation for superb ride and
handling. A unique extruded aluminum engine cradle helps isolate engine noise
and vibration, and the overall tautness of the Monte Carlo's body structure
allows the four-wheel independent suspension, with MacPherson struts, to be
finely tuned to enhance performance.
Specific chassis and suspension changes provide the Monte Carlo
Supercharged SS with sportier ride and handling capabilities. Spring rates are
increased both front and rear, and the rear ride height is lowered by 10 mm.
Larger 34-mm front and 19.5-mm rear stabilizer bars (compared to 30 mm/17.2 mm
in Monte Carlo LS), refinements to the rear trailing link and rear strut
mounts, plus speed-rated Goodyear P235/55R17 W-rated tires mounted on 17-inch
cast aluminum wheels complete the performance package.
Comfort and convenience abound
Monte Carlo has as much as 7 more cubic feet (198L) of interior room than
any non-GM competitor in its class. In Monte Carlo's roomy yet sporty
interior, the list of standard equipment includes:
