More power for 2007.
Bigger, better breathing engines headline a list of improvements to the 2007 Chevy Colorado line of mid-size pickups.
The base-level four-cylinder engine has been bored out from 2.8 to 2.9 liters, and the 2007 model produces 185 horsepower and 190 pound-feet of torque. That's 10 horsepower and 5 more pound-feet than 2006. The optional five-cylinder engine has been enlarged from 3.5 to 3.7 liters for 2007, for 242 horsepower and 242 pound-feet, up about 20 over the 2006 figures.
Other improvements for 2007 include a smoother-shifting automatic transmission, a more powerful 125-amp alternator, a standard tire-pressure monitor, and brighter interior trim.
Chevy Colorado was designed for comfort and favors roominess, ride comfort and fuel efficiency over traditional truck virtues such as payload and towing capacity. That's a strong selling point because mid-size trucks are often bought as alternatives to cars, and their owners want more hip room, leg room and head room. Most are willing to sacrifice bed length for cab room.
We think the trade-offs have paid off. The Chevrolet Colorado rides smoothly and feels refined. Order the five-cylinder engine and it accelerates smartly. The Crew Cab features a roomy back seat that's surprisingly comfortable and not bolt-upright. Yet the Colorado fits into tight parking spaces, something that can't be said of full-size pickups. Like all the trucks in this category, the Colorado is substantially smaller and more maneuverable than full-size pickups such as the Dodge Ram or Chevy Silverado. These are important benefits because even those who frequently use pickups to perform genuine truck duties spend most of their time driving with an empty bed.
But don't get us wrong: The Colorado isn't a car with a bed. In fact, the Colorado provides all the trucking capacity most owners will ever use. It has a six-foot bed with Regular and Extended Cabs, and a five-foot bed on Crew Cabs. A properly equipped Colorado is rated to tow 4,000 pounds, enough for transporting ATVs, dirt bikes, personal watercraft, bass boats, and small camping trailers. For most consumer needs, Colorado is more than enough truck to get the job done.
Colorado also offers a utilitarian Regular Cab work truck, a relatively inexpensive vehicle for buyers who want a tool for their work. All told, about a hundred permutations of the Colorado are available, giving buyers lots of choices to fit their needs.
The 2007 Chevrolet Colorado is available in Regular Cab, Extended Cab, and Crew Cab configurations. Regular and Extended Cabs come with a six-foot bed. Crew Cabs come with a five-foot bed.
Three suspension packages are offered: The rugged Z85 is the standard setup and is available with two-wheel drive (2WD) or four-wheel drive (4WD). The Z71 off-road suspension is also available with 2WD and 4WD. Appropriately, the low-riding ZQ8 sport suspension is only available with 2WD.
New for 2007, the 2.9-liter four-cylinder engine, rated 185 horsepower, comes standard all Regular and Extended Cabs, and on 2WD Crew Cabs with the Z85 suspension. Also new for 2007, the 3.7-liter, 242-hp inline-5 is optional ($1,000) on those models and standard on Crew Cabs with ZQ8, Z71, and/or 4WD. It is also included in the more up-level trim packages.
In Regular and Extended Cabs, a five-speed manual transmission is standard with either engine, and a four-speed automatic ($1,095) optional. The automatic is now standard in all Crew Cabs and with some up-level trims.
The base-trim model is a commercial-grade work truck (W/T), offered as a Regular Cab 2WD ($13,910), Extended Cab 2WD ($16,310), Regular Cab 4WD ($17,310) and Extended Cab 4WD ($19,510). Only the standard suspension is available. All come with hose-it-out vinyl floor mats and durable vinyl seating, ideal for muddy-boot applications (and situations where the buyer isn't the same person as the driver). Air conditioning is standard, though, along with tilt steering, a tachometer, driver information center, AM/FM stereo, cruise control and two 12-volt power outlets. Cloth seats ($58) and carpeting ($70) are available.
The LS trim level makes cloth upholstery standard, adds some brightwork to the interior, features chrome instead of charcoal bumpers, and rides on 225/75R15 tires rather than the standard 205/75R15s.
LT trim adds reclining seats with upgraded upholstery, metallic interior trim, more stereo speakers, color-keyed grille and side moldings, and aluminum wheels. To that the 2LT Package adds bucket seats; power windows, mirrors and locks with remote keyless entry; deep-tinted glass; and a self-dimming rearview mirror. It also makes the five-cylinder engine and automatic transmission standard. Package 3LT includes all 2LT equipment plus additional upgrades like carpeted floor mats, a sliding rear cab window, and fog lamps.
The Z71 off-road suspension requires a minimum of LT trim, and adds an automatic-locking rear differential, P265/75R15 on/off-road tires, and a Smoke Gray grille and wheel flares. Ground clearance at the rear differential is 8.4 inches. Order 4WD and you get skid plates, too.
The ZQ8 sport suspension also requires LT trim, and is offered only with 2WD. The ZQ8 rides lower than base models, with a slight forward rake, and comes with P235/50R18 tires on 18-by-8-inch aluminum wheels. A monochromatic paint scheme and fog lamps add visual distinction.
Colorado Xtreme drops the ZQ8 suspension down another 1.6 inches and mounts gas-charged shocks and stiffer anti-roll bars. A unique grille, tailgate spoiler, and side-sill extensions add exclusivity to Xtreme's appearance, along with monochromatic paint schemes limited to red, black, white, blue, or yellow.
Power windows, locks and mirrors are optional ($500) on LT; so are XM Satellite Radio ($199), Gen 6 OnStar ($695), a six-CD changer ($395). A sunroof ($695) is offered on Crew Cabs. A Sun and Sound package ($795) for LT Crew Cabs bundles the sunroof with a six-disc in-dash CD changer. Crew Cabs offer leather seating surfaces ($1,495). Other options and accessories are available as well.
Safety features include dual-stage front airbags and front seatbelt pre-tensioners. Curtain-style side-impact airbags designed for head protection are optional ($395) on all models. Four-wheel anti-lock brakes (ABS) come standard on all models. A tire pressure monitor, also standard on all models, is.
The 2007 Chevy Colorado looks very much the same as it did in '06. There have been some changes on the paint chart, and LS and LT models now wear identifying badges. The popular 15-inch cast-alloy wheels are now offered in chrome as well as natural-look aluminum.
Colorado looks like a downsized and slightly Picasso-ized rendition of the full-size Silverado, beginning with its bold chrome horizontal-bar grille and multi-lens headlamps. The lamp assembly has a flying wedge contour, higher at the outside, and houses high and low beams, daytime running lamps and turn signals. On models so equipped, fog lamps are inset into the bumper.
Overall, the Colorado has a clean, modern look. The fender bulges are angular and aggressive, more so than Silverado's. The leading edge of the front fender flares isn't finished elegantly, however. Reach-through door handles allow a full handful of grip for easy opening, even with gloves.
The Crew Cab looks well balanced despite the extra cab length. Cargo boxes are 6-foot, 1-inch on Regular and Extended Cab models and 5-foot, 1-inch on Crew Cabs. A two-position locking tailgate, which opens to 55 degrees or to fully horizontal, provides more cargo utility. When the tailgate is partway down, the Colorado can carry a 4-by-8 foot sheet of plywood flat, supported by the wheel wells and the rear edge of the tailgate.
Ride height varies by suspension grade and has a dramatic effect on the truck's appearance. The ZQ8 Sport models look slammed with their lower ride height; although with 18-inch wheels for '07, their minimum ground clearance is just about an inch less than that of the standard 2WD Colorado. The standard Colorado has about 7.4 inches of ground clearance with 2WD and 7.7 inches with 4WD, varying slightly with cab style. The Z71 off-road suspension raises the ground clearance to around 8.8 inches, with 2WD or 4WD.
All Crew Cab and Extended Cab models ride on a 126-inch wheelbase, while Regular Cab models ride on a 111-inch wheelbase. Overall length is 207 inches for all but Regular Cabs, which are 192 inches long. Overall height is about 65 inches for the standard Z85 suspension, 68 inches with 4WD.
Chevy Truck dealers offer a range of accessories, including a bed extender, hard and soft tonneau covers, tubular assist steps and splash guards. All can be installed at the time of delivery and can be financed as part of the deal.
For 2007, Chevy has dressed up Colorado's interior (all but the base-level W/T, that is) with chrome accents added to door handles, air outlet control knobs, front door sill inserts, small speaker bezels, and instrument cluster trim rings. The center stack and HVAC trim are now painted silver, and cloth has been added to the door insert padding.
Otherwise, however, Colorado's interior is swathed in hard plastic that's not finger friendly but should prove to be durable, important in a working truck. Inside door releases feel solid and sturdy, but have the same hard feel. The leather-wrapped steering wheel is well cushioned, however, and feels good in hand and should remain comfortable for the long haul.
The optional front bucket seats are wide and soft, and lack lateral support, whether upholstered in cloth or leather.
Each door panel has a molded map pocket contoured for a bottle or can. The center console has cup holders that look capable of handling a variety of drink containers. The center armrest opens into a small storage space, big enough for a large wallet, but it wobbles when pushed. A small tray on the console is useful.
Instruments are traditional white-on-black with orange needles. They are easy to read and don't hide their functionality with artsy markings. This practical approach continues to the center stack. No ground-breaking innovation here, just straightforward knobs and dials that don't require a postgraduate degree to operate. Turning on the dome light requires fumbling around for a small thumbwheel, however, which we found difficult while navigating in pre-dawn darkness. For this reason, we recommend the optional electrochomic (automatic-dimming) rearview mirror, which features map lights, compass and outside temperature display. Light switches on mirrors often lead to thumbprints and frequent mirror adjustments, but in this case they're a step up.
The Crew Cab's back seat is surprisingly comfortable, particularly when compared with the back seats of old-generation compact Crew Cabs. There's a reasonable amount of leg room, especially with a little cooperation from those sitting in front, and the seat is comfortably high. The seatback angles back slightly, making it more comfortable than the bolt-upright backrest found in some other pickups. The wide cabin provides enough shoulder room for adult males, but don't expect the width of a full-size pickup. Getting in and out of the back seats is a little awkward because the door is relatively narrow and you have to swing your feet in to clear the wide B-pillar (the post between the front and rear doors).
Forget about sitting in the back of an Extended Cab. It has back seats, but they're only good for hauling kids short distances. The rear seats flip down, providing a good place for cargo and with modifications it would be okay for a medium-size dog. The rear doors are rear hinged, meaning they swing open suicide-style.
Chevy Truck appears to have struck the right balance between capability and comfort for its midsize pickup. Colorado rides like a truck, but it isn't nasty about it. By aiming for a more modest towing capacity, GM engineers were able to reduce the rear spring rate and tune the suspension for a smooth ride. The rear end doesn't bounce around on washboard dirt roads the way it does on older trucks. It's the front end that feels firmer.
Up until 2007, the standard Colorado engine has been a 2.8-liter inline-4 rated at 175 horsepower. It delivered acceptable acceleration, and seemed adequate for most mid-size pickup-truck duties, particularly when paired with the five-speed manual transmission. We expect the new 2.9-liter version, with 185 horsepower at 5600 rpm and 190 pound-feet of torque at 2800 to perform better, but not dramatically so.
For 2007, the optional inline-5 displaces 3.7 liters and develops 242 horsepower and 242 pound-feet of torque, up from 220 and 225 for 2006. That might make more of a difference, although it's still a bit weak compared to the optional 4.0-liter V6 engines in the Toyota Tacoma and Nissan Frontier, both of which rate north of 260 pound-feet of torque. Dodge Dakota's top V8 boasts 310 pound-feet of torque now, and will have 320 for 2008, but the Dakota is a bigger, heavier truck. In the Colorado's defense, we should point out that the inline-5 sustains its peak torque over 90 percent of its rev range, which is important when hauling heavy loads or towing trailers. The maximum towing load for the Colorado with the five-cylinder engine and automatic transmission is 4000 pounds, compared with 6500 for the V6 Tacoma, 6100 for Frontier, and 7150 for the max-V8 Dakota. On the other hand, Colorado runs happily on 87 octane regular. Toyota recommends (but does not require) premium for its V6.
A five-cylinder engine is an unusual configuration for a U.S. vehicle, but German automakers have been using them for years. Mercedes-Benz offered five-cylinder diesels in the '70s, and Audi's premier engine was in inline-5 from 1977-91. More recently Volvo has adopted the straight-five idea. All of these engines produce a distinctive, siren-like sound at full throttle, and so does the five-cylinder Colorado. At cruise, however, GM's five-cylinder is quiet, and there's no indication that it's anything out of the ordinary. If you like inline-6 engines better than V6s, then you'll like the inline-5 just fine. It's much more responsive than the four-cylinder and delivers quicker acceleration. It's also smoother. Just don't mention the number of jugs it has in a cowboy bar.
Both Colorado engines were derived from the Vortec 4200 inline-6 used in the Chevy TrailBlazer. GM lopped cylinders off the six to get the five and four. These are modern engines featuring all-aluminum construction, dual overhead camshafts with four valves per cylinder, variable valve timing, electronic (drive-by-wire) throttle control, and a high 10:1 compression ratio.
For 2007, both Colorado engines are not only larger (thanks to a bigger, 3.76-inch cylinder bore), but greatly improved, with larger intake and exhaust valves, revised cam profiles, new 2M electronic control module, and a number of refinements to reduce noise.
Colorado accelerates decently in traffic and the Hydra-Matic 4L60-E four-speed automatic should shift even smoother in '07, thanks to a new input speed sensor. But goose it on loose gravel or dirt, and the traction control system shuts down the power and the Colorado bogs. We discovered this when trying to merge into fast-moving traffic from a pebbly roadside. The traction control override button, located high on the dash, can be used in such a situation, but obviously you'll need to think that through in advance. In snow, however, the traction control should help in taming the pickup's lightly loaded rear end.
The brakes are big and m.
Chevy Colorado offers the increased roominess of the newest generation of mid-size pickup trucks. Anyone looking for a smaller truck that's not cramped on the inside, but is still capable of handling a respectable load or pulling a lightweight trailer, should find the Colorado a good choice. Load three dirt bikes on a trailer, and assorted gear in the bed, and three bikers and a couple of hangers-on can head to the track. Or take the kids to soccer practice and bring home a dozen bags of mulch. The Colorado handles it all with aplomb.
