Chevrolet launched the compact Colorado pickup truck in 2004. Offered with a four- or five-cylinder engine, the Colorado is closely related to the GMC Canyon. For 2007, Chevrolet swaps both engines for larger versions, netting a power increase of up to 10 percent. New wheel choices, a mild interior update and an improved transmission round out the major changes.
Colorados come with two- or four-wheel drive and in regular cab, extended cab and Crew Cab configurations. In addition to the standard suspension, both a Z71 offroad performance suspension and a ZQ8 low-riding sport suspension are available. Two trim levels are offered: LS and step-up LT. The Xtreme edition includes the ZQ8 suspension, a unique body-colored front fascia with fog lamps, rocker extension moldings and monochromatic paint in a choice of four colors.
A Sun & Sound Package with a sunroof and in-dash six-CD changer is available for the LT edition. Upgraded cloth upholstery goes into the LT and onto seatbacks of Crew Cab models. A Street Pack option adds a color-keyed appearance to base, regular-length extended cab models.
The Colorado's styling has been called aerodynamic, angular and athletic. The Colorado has an independent front suspension and a solid rear axle.
Regular cab trucks are 192.8 inches long overall on a 111.2-inch wheelbase, while extended cab and Crew Cab models measure about 207 inches long on a 125.9-inch span. Standard steel wheels measure 15 inches in diameter, but aluminum or chrome wheels are available. The ZQ8 package includes 17-inch tires, and 18-inch tires are mounted on models with the Xtreme option. Hydraulically assisted rack-and-pinion steering is installed.
For 2007, several interior details — include door handles, instrument gauge surrounds and climate controls — receive chrome accents on some LS and LT models.
Extended cab Colorados have four doors and forward-facing rear seats. Crew Cab models have a 60/40-split, folding rear seat that holds three adults. Regular cab trucks feature a 60/40-split bench seat upholstered in cloth or leather, and bucket seats are available.
Options include remote keyless entry, heated leather seating, General Motors' OnStar communication system and XM Satellite Radio.
Under the Hood
A new 2.9-liter engine utilizes variable valve timing to make 185 horsepower and 190 pounds-feet of torque, both of which represent gains over the outgoing 2.8-liter engine. Last year's 220-hp, 3.5-liter inline-five is also canned for a new 3.7-liter engine that makes 242 hp and 242 pounds-feet of torque. Five-speed manual or four-speed automatic transmissions are available.
Chevrolet's shift-on-the-fly four-wheel-drive system operates with a dashboard-mounted switch. A locking differential is optional, and rear-drive models can be equipped with traction control.
When properly equipped, a four-cylinder Colorado can tow up to 3,500 pounds. The larger engine enables 4,000-pound towing.
Front disc and rear drum antilock brakes are standard. Dual-stage front-impact airbags are standard, and roof-rail side curtain airbags are optional. Side-impact airbags for the front seats are not available.
