2010 Chevrolet Silverado 1500
2010 Chevrolet Silverado 1500 Expert Review:Autoblog
With the 2009 editions of the Chevy Silverado and GMC Sierra Hybrids just now beginning to appear on dealer lots around the country, we decided it would be a good idea to strap ourselves behind the wheel of the fuel-saving duo to see what fuel efficiency improvements we could manage in some typical city driving scenarios. Plus, there's all kinds of techno-wizardry at play as soon as the driver's right loafer touches the go-pedal, so we were keenly interested to see if The General was able to harness the power of three distinct power sources (one gas engine, two electric motors) while keeping everything smooth and controlled as one would expect from a $40,000 pickup truck.

Detail enhancements for Chevy's full-size pickup.
The Chevy Silverado needs no introduction. If you're in the market for a full-size pickup you know what it is and what you can expect it to do. Since all full-size pickups are available in exceptionally wide ranges of sizes, engines, and capabilities, it's of primary importance to analyze your own needs and then select the Silverado that best serves those needs.
For 2010 there have been some detail enhancements to the Silverado 1500. A 3.08:1 axle ratio and fuel saver mode is standard with the 5.3-liter V8 for improved fuel economy, resulting in 15 mpg city/21 mpg Highway for 2WD models. There is E85 FlexFuel capability on the 4.8-liter, 5.3-liter, and 6.2-liter engines. Variable valve timing on the 4.8-liter and 5.3-liter engines improves fuel economy. A six-speed automatic transmission is on Regular Cab and Extended Cab models with the 5.3-liter V8. USB connectivity is on all except the base radios. On the safety side, side-curtain airbags and seat-mounted side airbags, and the StabiliTrak electronic stability control system, are standard on all 2010 Chevy Silverado 1500s.
The base engine is a 4.3-liter V6 (195 hp/260 lb-ft of torque) with a four-speed automatic, offered only on Regular Cabs and 2WD Extended Cab models with the standard bed. The 4.8-liter V8 (302 hp/305 lb-ft of torque) and four-speed automatic are standard on Crew Cab and 4WD Extended Cab models with the standard bed, and on many LT models.
The 5.3-liter V8 (315 hp/338 lb-ft of torque, or 326 hp/348 lb-ft of torque on E85), with active fuel management that shuts off cylinders to save fuel, and iron or aluminum block, is standard on most LTZ models and is matched with a six-speed automatic.
The top engine is a 6.2-liter V8 (403 hp/417 lb-ft of torque) available on Extended Cab and Crew Cab models; it uses the six-speed automatic.
XFE (Xtra Fuel Economy) models use a 5.3-liter V8, six-speed automatic and cruising-biased axle ratio of 3.08:1 to increase EPA ratings. XFE versions feature aerodynamic upgrades in the form of a soft bed cover and extended front air dam, plus aluminum wheels (including the spare) and lower front suspension arms, locking rear differential, and low rolling resistance tires. A trailering package is standard so XFE models can tow up to 7000 pounds.
The Hybrid, available only in the Crew Cab body style, uses a 6.0-liter V8 (332 hp/367 lb-ft of torque), battery pack, and four-speed automatic with two electric motors in it. EPA ratings are 21/22 mpg. Tow ratings are available to 6100 pounds, and maximum payload is in the 1400-pound range.
The 2010 Chevy Silverado is available in four trim levels: WT, LS, LT, and LTZ. Packages often upgrade amenities without upgrading engines or body styles.
The WT ($20,850) is a basic work truck that comes with a driver information center, AM/FM/XM stereo, 40/20/40 split-bench, vinyl-covered front seat, dual glove boxes, two auxiliary power outlets, tire pressure monitoring system, OnStar and a four-speed automatic transmission. The LS Crew Cab ($30,360) offers lots more in the way of features.
The LT ($26,810 for Regular Cab, 2WD) adds a cloth-covered front seat with lockable storage under the seat, a CD player and MP3 compatibility, power windows/locks/mirrors, remote keyless entry, auto-dimming rearview mirror with compass and outside temperature displays, chrome front bumper and 17-inch styled steel wheels, and power folding and heated exterior mirrors. LT models can be upgraded with premium cloth front bucket seats with six-way power adjustment, dual-zone automatic temperature controls, audio controls mounted on the steering wheel, fog lamps, aluminum wheels, chromed bumper, and a spare tire lock.
The LTZ ($35,280 for Extended Cab, 2WD) adds heavy-duty trailering equipment, an automatic locking rear differential, body-colored bumpers, reclining and heated leather front seats with 12-way power, an in-dash six-CD changer with Bose speakers, 18-inch wheels, turn signal indicators in the exterior rearview mirrors and heated windshield washers.
Extended Cab and Crew Cab models have back seats and windows in the side doors that power down. The Crew Cab has four front-hinged doors, much like a sport utility vehicle. The Extended Cab has rear access doors hinged at the rear that open to 170 degrees to provide full access to the rear seating area. The Regular Cab can be outfitted with a standard bed (6-foot, 6-inch) or long bed (8-foot). The Extended Cab also offers a short (5-foot, 8-inch) bed. The short bed (5-foot, 8-inch) is the only bed available on the Crew Cab.
Five suspensions are available: Z83 is the standard setup designed for a smooth ride; Z85 is a little firmer for enhanced handling and towing; Z71 is for off-road driving and includes 18-inch wheels; Z60 is for maximum street performance and includes 20-inch wheels; NHT is for maximum towing capacity (bigger rear axle with locking differential, HD cooling, and so forth) and includes high-capacity rear springs as well as all-terrain tires.
Option prices vary by trim level and body style. Among them: A power sliding sunroof ($995), 20-inch wheels/suspension ($1,045), a power sliding rear window ($250), rear-seat entertainment system ($1,480), and navigation system ($2,250). Options on lesser models include the locking differential ($325) and various levels of towing packages.
Safety features on all Silverado models include dual front airbags, anti-lock brakes, tire-pressure monitoring system, side-curtain airbags, and StabiliTrak electronic stability control with rollover mitigation technology.
The Chevy Silverado may not have the aggressive styling of some other pickups, but its upright design may be considered appealing to its faithful customers, and they buy hundreds of thousands of Silverados each year. We think it's quite attractive.
A raked windshield (angled at 57 degrees) and careful aerodynamic and body-building engineering make the truck quiet on the inside and contribute to fuel efficiency. GM boasts that the Silverado and GMC Sierra are the first full-size trucks to offer both 300 horsepower and EPA highway ratings of 20 miles per gallon or better.
The large, gold Chevy bowtie badge is set against a wide, three-bar chrome grille. The grille is flanked by stacked headlights sporting the latest reflector optics. The front bumper incorporates rectangular fog lights.
The hood has a wide power dome. Bulging front fenders wrap over the front wheels and incorporate the headlights within their forward sweep. Likewise, the rear quarter panels are punctuated by large faired wheel wells.
The rear view of the truck features stacked tail lights on either side of a tall tailgate that has a sculpted center section that mimics and inverts the shape of the fender flares.
Built on what General Motors calls its GMT900 platform, the Silverado shares much of its underpinnings with the Tahoe SUV, though the pickup gets a unique rear suspension and a frame section 245-percent stiffer than that of the SUV. The current Silverado chassis is far more rigid than that of the previous generation, which allows the engineers to reduce the gaps between the truck bed and passenger compartment and between fenders and bumpers. This stiffer frame also allows suspension components to be designed for improved ride and handling characteristics as well as allowing enhanced aerodynamics and fuel efficiency.
The front suspension uses coil-over shock absorbers (rather than torsion bars) and the rack-and-pinion steering gear is mounted to the engine cross member to provide enhanced control and feedback. The Silverado benefits from a rear axle design featuring shocks absorbers mounted outboard and more upright for better dynamic control than that of the previous-generation models.
The Silverado WT, LS and LT come with what Chevy calls the pure pickup interior while the LTZ features a more luxurious interior.
The pure pickup interior is more driver and work oriented, includes two glove boxes in the dashboard, one of them just about the right size to hold a pair of work gloves and a few small items, and a 40/20/40-split front bench seat with the center section of the seat back folding down to form a wide arm rest with lots of storage capacity. This interior features large switchgear controls and interior door handles designed to be easily manipulated even while wearing bulky gloves.
The more luxury-oriented interior includes bucket seats with a permanent center console with 20 liters of storage capacity. The center stack puts ventilation and audio controls within easy site and reach of the front seat passenger. This version has a single glove box in the dash.
XM Satellite Radio with current traffic conditions and Bluetooth may be ordered, or alternately, OnStar 8.0 with destination download and turn-by-turn navigation. We like both.
Extended Cab models feature stadium-style seating with an elevated view for those sitting in the second row. Both the Extended Cab and Crew Cab versions offer plenty of rear legroom. The rear-seat bottoms can be easily folded up to provide more room on the floor for cargo. Rear seats are split 60/40 so one side can be folded up for cargo while the other is used for seating.
Chevrolet says the interior of the Silverado is 20 percent quieter than its predecessor (pre-2007 and Silverado Classic models), thanks to enhanced insulation materials, much like those used in the company's sport utility vehicles, and to aerodynamic improvements that reduce wind noise.
Choosing the right cabin configuration depends on how you expect to use the truck and what you expect from it.
An LTZ interior mirrors those of GM's full-size sport-utilities and is modeled more like a big touring sedan than a truck. It's a smooth, cohesive design with a central console that rises to a wall of smallish white-on-black buttons you can't operate with mittens like those on the pure pickup. The navigation system is up high for good viewing, intuitive in operation, and offers many choices in radio station memory. The LTZ cabin is available in three interior colors and, though it will show dirt faster, the lightest color gives the most luxurious impression.
The WT/LT version is a conventional truck with a more open floor area, space for random stuff all over, and no concerns that something might get scratched, scuffed or dirty. Modern electronics suggest hosing out a truck interior isn't a good idea anymore, but a shovel and stiff bristle brush should get it done.
Suspension choice is key to the driving characteristics of the Chevy Silverado. The basic Z83 suspension is best chosen for budget constraints (or if you plan to make modifications and throw away the stock parts). The Z85 is similar except that it uses better shock absorbers and is calibrated for how today's light-duty pickups are often used as daily transportation. The Z71 package is designed for off-highway use and makes maximum use of suspension travel to keep the wheels on the ground when on the trail or dirt roads; this off-road package frequently provides the best ride quality on anything worse than glass-smooth interstates. The Z60 street package replete with 20-inch wheels and low-profile tires is best used for the highway and smooth two-lanes but can be used on a dirt road. The NHT package is designed for maximum loads; ride compliance is good based on how much weight it can carry and tow but driving it around empty may be firmer (harsher) than you want for everyday use.
The Silverado benefits from good brakes. Drivers who tow will appreciate the optional integrated brake controller like that used on the Silverado heavy-duty trucks. (However, be sure your trailer brakes are compatible with it before choosing the option, as some electro-hydraulic disc conversions do not work with the integrated controller.)
Towing capacities range as high as 10,700 pounds with the NHT package. Maximum tow ratings for other models are in the 8000-8900 pound range (Hybrid excepted). If your trailer is heavier than 6,000 pounds or so, we'd recommend looking at the heavy-duty Silverado HD models. Remember these trailer weights are usually quoted for an empty truck with a standard-size driver (154 pounds) on board. If you're hauling a lot of gear and people, you need to take that into consideration.
If you want the 15/22 mpg EPA ratings of the XFE on a regular Silverado or need higher towing capacity, minor changes to driving style will routinely net the same (or better) economy increase.
Those with limited vertical clearance either at home or in commercial garages should note that the 4WD versions of the Silverado 1500 Extended Cab and Crew Cab models are fractionally lower at the roof and loading level than the 2WD versions. Some pickup trucks add two to three inches in height for 4WD, and those inches could be critical in tight fits.
The Chevy Silverado offers more choices in light-duty pickup variations than any other, except perhaps GMC and the Ford F-150. It is among the smoothest riding and quietest of all full-size pickups, and can be counted on to get the job done.
