truck’s capability is inextricably linked to its horsepower
and torque output – and the 2007 Chevy Colorado answers customers’
calls for more of both with new, larger and more powerful four-
and five-cylinder engines. A new, 2.9L DOHC four-cylinder with variable
valve timing (VVT) replaces the previous 2.8L four-cylinder and
delivers 185 horsepower and 190 lb.-ft. of torque. A new, 3.7L DOHC
five-cylinder with VVT replaces the previous 3.5L engine and is
rated at 242 horsepower and 242 lb.-ft. of torque.
new 2.9L engine produces approximately 6 percent more horses and
about 3 percent more torque than the previous four-cylinder, while
the new 3.7L engine offers a substantial 10 percent increase in
horsepower and nearly 8 percent more torque than the previous five-cylinder
engine. The 2.9L is standard in all models except 4WD Crew Cab and
the 3.7L is available (standard on 4WD Crew Cab).
changes for 2007 include:
powerful 125-amp alternator replaces previous 100-amp unit
tire pressure monitoring system is standard on all models
new transmission input speed sensor helps improve shift quality
new exterior colors: Pace Blue, Imperial Blue Metallic and Deep
Ruby Metallic ( Superior Blue Metallic and Cherry Red Metallic are
and LT exterior badging returns
chrome-finish version of the popular 15-inch, five-spoke wheel
accents added to uplevel LS and LT interior trim, including door
handles, air outlet control knobs, front door sill inserts, small
speaker bezels, instrument cluster trim rings
Ebony trim color available on LS and LT
stack and HVAC trim painted Nova Silver on LS and LT
added to door insert padding with LS and LT.
continues to offer one of the widest model ranges, including Regular
Cab, Extended Cab or Crew Cab body styles; two pickup bed lengths;
three available suspensions; and two inline engines. Vehicles are
offered in WT, LS and LT trims. The popular Colorado Xtreme combines
performance with an attractive sport-truck appearance package.
and Sound package is available for LT models and includes an AM/FM
with six-disc in-dash CD stereo and power sunroof. LT models also
receive upgraded interior cloth material, as does the seatback of
Crew Cab models. The Street Pack offers a great, color-keyed appearance
to base, regular-length extended cab models.
Colorado can seat up to six while offering much higher levels of
ride comfort, handling, quietness and interior space than many other
midsize trucks. Standard features include rack-and-pinion steering,
intermittent wipers, air conditioning tilt steering wheel, cruise
control and folding outside mirrors. Insta-Trac is standard on 4WD
optional equipment includes remote keyless entry; traction assist
(2WD models); XM Satellite Radio; fog lamps; self-dimming inside
rearview mirror; running boards; power, heated leather seating;
high-back bucket seats; a rear sliding window; and power operated
outside rearview mirrors.
’s instrument panel has large, easy-to-read analog gauges,
with switches and controls designed for easy operation with gloves.
Crew Cab models offer a 60/40-split/folding rear seat capable of
accommodating three adults. Extended Cab versions have four doors,
and its two folding rear seats face forward.
and Extended Cab models have a 6-foot 1-inch pickup bed with taller
sides than many competitors, providing best-in-class volume for
deeper storage and higher overall payload. Crew Cab bed lengths
are 5-foot 1-inch. Both beds offer two-tier cargo loading, and tailgates
that are both lockable and easily removable.
Colorado ’s tailgate opens fully to almost 90 degrees, but
can be set at a 55-degree opening. That puts the tailgate edge at
the same height as the top of the rear wheel wells within the cargo
box, creating a sturdy, flat platform to conveniently transport
longer items or 4-foot by 8-foot panels.
its efficient packaging, Colorado looks and feels more like a spacious
full-size pickup than a typical midsize truck. Colorado has a stiff
frame that enables more precise suspension tuning to deliver a smooth,
isolated ride without sacrificing responsive handling. Colorado
also delivers class-leading refinement with features such as hydraulically
assisted rack-and-pinion steering; large front disc brakes with
twin-piston calipers; coil-over front suspension on 2WD models and
torsion bar front suspension on 4WD models; and specifically tuned
body mounts that help reduce interior noise and vibration.
suspension choices let customers tailor Colorado to their specific
needs: the rugged Z85 suspension standard on 2WD or 4WD models;
the lower-riding ZQ8 sport suspension for 2WD models only; and the
Z71 off-road suspension, now available in both 2WD and 4WD.
New for 2007, Colorado offers larger, more powerful inline four-
and five-cylinder engines. Standard on all models except 4WD Crew
Cabs is a 2.9L DOHC four-cylinder engine, rated at 185 horsepower
and 190 lb.-ft. of torque – increases of 10 horsepower and
5 lb.-ft. more than the previous four-cylinder. A new, 3.7L DOHC
five-cylinder is standard on 4WD Crew Cabs and available on all
other Colorado models; it is rated at 242 horsepower and 242 lb.-ft.
of torque – increases of 22 horsepower and 17 lb.-ft. over
the previous five-cylinder.
new engines are based on GM’s modular inline engine design,
which also serves as the foundation for the 4.2L inline-six engine
of the Chevy TrailBlazer. They feature dual overhead camshafts,
variable valve timing, electronic throttle control and other features
that contribute to high levels of operating efficiency and fuel
economy. Balance shafts help ensure smooth operation of the engines,
providing a higher level of refinement.
addition to their larger displacement – delivered through
larger, 3.76-inch bores – the 2.9L and 3.7L engines feature
improved airflow in and out of the combustion chambers, which helps
boost power. They also share additional upgrades and changes, compared
to the previous Colorado engines:
1.52-inch intake valves, vs. previous 1.45-inch intake valves
1.32-inch exhaust valves, vs. previous 1.18-inch exhaust valves
camshaft profile optimizes valve lift and duration in accordance
with larger valves
head airflow increased to match capabilities enabled by larger valves
and revised camshaft
noise-reducing oiling system uses cylinder wall squirter system
enabled by a hole in each connecting rod that delivers a precise
oil stream onto the cylinder wall beneath the piston
aluminum camshaft cover helps reduce noise
balance shaft bushings promote quieter operation
