Living up to its name, the 2006 GMC Sierra 1500 Work Truck Regular Cab is intended for functionality rather than personal comfort. The half-ton, rear-wheel drive pickup rides on a short and long arm front and solid live axle rear suspension, with a pickup bed measuring 6.5 feet in length. The two-door truck seats two or three in a front row split-folding bench. Standard powertrain consists of a 4.3-liter V6 and choice of 5-speed manual or 4-speed automatic transmission. These put out 195-hp and 260 ft-lbs of torque at a low 2800 RPM. Towing power reaches 8400 pounds with the optional trailer hitch. Tow hooks are standard. Also optional is a 285-hp 4.8 V8 or a 295-hp 5.3 V8 in both regular and flex fuel formats.

Earning only three and four stars in crash tests, the 2006 Sierra 1500 Work Truck Regular Cab comes equipped with dual front airbags, front disc and rear drum brakes, a front stabilizer bar, and four-wheel ABS brakes with electronic brakeforce distribution. The pickup rides on 17-inch steel wheels with all-season tires. Automatic headlights and daytime running lights are standard. A locking rear differential is available, but OnStar and traction control are not part of the options package for the Work Truck.

Driver-oriented features include a radio, air conditioning, intermittent wipers, a tachometer, front power outlet, two front cupholders, and tilt and power steering. More upscale features cost extra, such as cruise control, power windows, locks, and mirrors, extendable mirrors, remote entry, and a CD player. The standard vinyl seats can be replaced with cloth. Chrome bumpers are not standard on the Work Truck, as with the other trims, but are available.

At 224 inches in length and with a 133-inch wheelbase, the 2006 GMC Sierra 1500 Work Truck Regular Cab LB carries a longer 8-foot cargo bed for more capacity and versatility. The two-door rear-wheel drive pickup resides in the half-ton division of the Sierra lineup. Power comes from a 195-hp, 4.3-liter V6 and 5-speed manual. They deliver 260 ft-lbs of torque and around 16/20 mpg. A 4-speed automatic is optional, as is a 4.8-liter, 285-hp V8 and a 5.3-liter, 295-hp V8. Tow hooks come standard with the bed, but the optional trailer hitch helps haul up to 8200 pounds.

Focused on function rather than form, the Sierra 1500 Work Truck LB comes minimally equipped with a radio, air conditioning, intermittent wipers, a front power outlet, a tachometer, and tilt and power steering. The front row bench is covered in vinyl and seats three people. It split-folds, but there is the option to substitute bucket seats. Other options add full power features, remote entry, extendable mirrors, cruise control, a CD/MP3 player, cloth seats, a manual sliding rear window, chrome bumper, and a locking rear differential.

Dual front airbags features passenger deactivation, while the front disc and rear drum brakes come with 4-wheel ABS and electronic brakeforce distribution. 17-inch wheels with all-season tires keep you on the road, along with the short and long arm front and solid live axle rear suspension. Automatic halogen headlamps and daytime running lights are also standard. Fully equipped, the pickup receives three and four stars in frontal impact tests.

The rear-wheel-drive, two-door 2006 GMC Sierra 1500 SL1 Regular Cab 4WD SB seats three people in one front-row bench, with a cargo bed 6.5 feet long. Tow hooks are standard, and an optional trailer hitch can tow up to 8,400 pounds with the 4.3-liter, 195-hp V6 engine. This engine is paired with either a 4-speed automatic or 5-speed manual transmission and serves up 260 ft-lbs of torque at a low 2,800 RPM. An available flex fuel 5.3-liter V8 adds more power. Front disc and rear drum brakes are supplemented by standard 4-wheel ABS brakes with electronic brakeforce distribution. Other safety features include dual front airbags, 17-inch wheels with all-season tires, and automatic headlights. Traction control and a rear locking differential are options.

The pickup has 8.4 inches of ground clearance and can be outfitted with optional skid plates. Built for utility rather than comfort, it still offers standard cruise control, a CD player, a tachometer, intermittent wipers, a front power outlet, and vinyl seats. Power locks, windows, and mirrors and remote entry cost extra, as do cloth upholstery, front bucket seats, a sliding rear window, and extendable mirrors.

The 2006 GMC Sierra 1500 Work Truck Regular Cab 4WD SB features part-time four-wheel drive with a center locking differential and high and low-range gearing for off-road capability. Suggested options for such activity include skid plates and a locking rear differential. The standard powertrain is a 285-hp, 4.8-liter V8 with 295 ft-lbs of torque at 4000 RPM. It is paired with either a 4-speed automatic or 5-speed manual. Though the half-ton pickup comes with tow hooks, adding an available trailer hitch lets you tow up to 9100 pounds. For more power, try the 5.3-liter, 295-hp V8 with 335 ft-lbs of torque. This is also available as a flex fuel vehicle.

The two-door pickup seats up to three people in a front row bench, which can be replaced with bucket seats. The pickup bed on the SB (short base) trims extends 6.5 feet. The truck rides on a short and long arm front and solid live axle rear suspension, with 17-inch steel wheels and all-season tires. The front disc and rear drum brakes come with 4-wheel ABS and electronic brakeforce distribution. Dual front airbags, a front stabilizer bar, automatic headlights, and daytime running lights complete the safety profile. The Sierra 1500 Work Truck earns only three and four stars in crash tests.

Features are kept to a minimum. Air conditioning, a radio, a tachometer, intermittent wipers, a front power outlet, and vinyl seats are what you'd expect from a utility vehicle. You can dress things up a bit with optional power features, remote entry, a CD player, extendable mirrors, cruise control, cloth upholstery, and a manual sliding rear window. Other options include chrome bumpers, a snow plow kit, and a manual sliding rear window.

If you need lots of cargo space, the 2006 GMC Sierra 1500 SL1 Regular Cab 4WD LB features an 8-foot cargo bed, about 1.5 feet longer than the standard bed. The Regular Cab features two doors opening onto a front-row bench that seats three, though optional bucket seats are available. This rear-wheel-drive pickup gets its power from a 195-hp, 4.3-liter V6 that gets 260 ft-lbs of torque at 2,800 RPM. A 5.3-liter V8, in regular or flex fuel form, is optional. Both engines comes standard with a 4-speed automatic, with the option to add a 5-speed manual transmission. Standard wheels are 17 inches, holding all-season tires.

With a dismal four and three stars in crash tests, the 2006 Sierra 1500 SL1 Regular Cab LB lacks standard side curtain airbags and stability control, even as options. Dual front airbags, 4-wheel ABS brakes with electronic brakeforce distribution, and a front stabilizer bar are standard, along with automatic headlights and daytime running lights. Traction control, skid plates, and a locking rear differential can be added. Comfort features include a CD player, cruise control, intermittent wipers, a front power outlet, tilt and power steering, and a tachometer. Options add power windows, locks, and mirrors, a sliding rear window, extendable mirrors for easier rearview vision, and remote entry. If vinyl is too sticky in the summer, cloth seats are also available.

Adding the part-time 4WD system to the 2006 GMC Sierra 1500 Work Truck Regular Cab 4WD gets you a stronger 4.8-liter V8 engine and choice of 4-speed automatic or 5-speed manual. This powertrain delivers 285-hp and 295 ft-lbs of torque at 4000 RPM. A 5.3-liter, 295-hp V8 that gets 285 ft-lbs of torque is optional. The four-wheel drive features a center locking differential and both high and low-range gearing for off-road use, though you may want to add skid plates to cover the 8.7 inches of ground clearance. A locking rear differential is also available.

This half-ton, two-door Work Truck measures 224 inches and carries an 8-foot bed. Tow hooks are standard, and an optional trailer hitch allows for 8900 pounds of towing power. The cabin seats two or three in one row, depending on whether you choose the available bucket seats or standard split-folding bench. A radio, air conditioning, intermittent wipers, vinyl upholstery, a front power outlet, tilt steering, and a tachometer are the barebones features, but a long options list adds power windows, locks, and extendable mirrors. Also available are remote entry, cruise control, a CD player with MP3 jack, a manual sliding rear window, and premium cloth seats.

The 2006 Sierra 1500 Work Truck Regular Cab 4WD LB rides on 17-inch wheels with all-season tires. Dual front airbags comes standard, along with 4-wheel ABS brakes and electronic brakeforce distribution. There are no available side impact airbags. In keeping with its utilitarian function, one option offered only with the 4WD Work Truck trims is a snow plow preparation kit.

For those needing a bit more passenger room to their pickup, the 2006 GMC Sierra 1500 Work Truck Extended Cab SB adds 15 more inches to the length and wheelbase in order to add a second row split-folding bench seat. The bed remains the same length in the short-base trim (6.5 feet long), but now there are four doors. However, the rear doors are not full-sized and do not open separately from the front ones. Another drawback is the 33.7 inches of rear legroom. The rear-wheel drive truck seats six, though front bucket seats are available.

The Work Truck starts with a 195-hp, 4.3-liter V6 and choice of 5-speed manual or 4-speed automatic, which deliver 260 ft-lbs of torque at 2800 RPM and around 16/20 mpg. Adding an optional trailer hitch to the standard tow hooks allows up to 8000 pounds of towing. Substitute engines include a 285-hp, 4.8 V8 and a 295-hp, 5.3 V8. There are no added features with the Extended Cab. A radio, air conditioning, tilt and power steering, intermittent wipers, and a tachometer round out the standard equipment. There is also a front power outlet and two cupholders. On the safety side, the 2006 Sierra 1500 Work Truck Extended comes with dual front airbags with passenger deactivation, 4-wheel ABS brakes and electronic brakeforce distribution, and 17-inch wheels with all-season tires. Daytime running lights and automatic halogen headlights take care of lighting.

There are plenty of options to make the Work Truck more comfortable. These include power windows, locks, and extendable mirrors, remote entry, cruise control, and a CD player. A manual sliding rear window is available, along with chrome bumpers, a locking rear differential, and cloth seats to replace the standard vinyl ones.

Blending a bit of luxury with pickup utility, the 2006 GMC Sierra 1500 SLE1 Regular Cab SB is a good fit for those who don't want to sacrifice comfort for functionality. The two-door, rear-wheel-drive pickup seats three in a front-row bench (bucket seats are optional) and comes with a 6.5-foot cargo bed equipped with tow hooks. The SLE1 Regular Cab upgrades from the SL1 with full power features, heated mirrors, remote entry, leather trim on the steering wheel and shifter, a compass and temperature readout, and upgraded cloth upholstery. These are in addition to already standard cruise control, a CD player with radio data, intermittent wipers, tilt and power steering, a front power outlet, and a tachometer. Satellite radio is optional.

The pickup is powered by a 4.8-liter, 285-hp V8 with 295 ft-lbs of torque at 4,000 RPM. This is matched to a 4-speed automatic. A 5.3-liter V8, available in a flex fuel version, is optional. An optional trailer hitch allows you to tow up to 8,400 pounds. The SLE1 rides on 17-inch chrome wheels with all-season tires.

Safety equipment includes 4-wheel ABS brakes with electronic brakeforce distribution, dual front airbags with passenger deactivation, a front stabilizer bar, and automatic headlights. The SLE1 adds standard foglights and an auto-dimming rearview mirror. However, this pickup earns average marks in crash tests. Traction control is available as an option, along with a locking rear differential and skid plates. New SLE1 options include OnStar, alloy wheels, and mirrors with turn signals.

There are many more options for the SLE1, including a power driver's seat with memory settings, a trip computer, and wheel-mounted audio controls.

The 2006 GMC Sierra 1500 SLE1 Regular Cab LB substitutes an 8-foot cargo bed for the 6.5-foot standard one, increasing cargo capacity while maintaining interior cabin space. The longer bed increases overall length by 19 inches. The two-door, rear-wheel-drive pickup seats three in one row, but comes nicely equipped with full power features, remote entry, heated extendable mirrors, and leather steering-wheel trim. A temperature display and compass join the tachometer. Also standard are cruise control, a CD player, intermittent wipers, tilt and power steering, a security system, and a front power outlet. Upgraded options include satellite radio, a power driver's seat with memory settings, wheel-mounted audio controls, and a trip computer.

Bucket seats can be substituted for the front-row bench. A rear sliding window is also available. The pickup gets its juice from a 285-hp, 4.8-liter V8 and 4-speed automatic, with the option to add a 5.3-liter, 295-hp V8 with flex fuel capability. 17-inch steel wheels are standard, but alloy wheels are available. The SLE1 adds foglights and an auto-dimming rearview mirror to the lighting package, which includes automatic headlights.

A front disc and rear drum brake setup comes with 4-wheel disc and ABS brakes with electronic brakeforce distribution. Dual front airbags earn three and four stars in crash tests. The SLE1 adds more safety options, such as mirrors with turn signals, OnStar, skid plates, a locking rear differential, traction control, and a trailer hitch to tow up to 8,200 pounds.

This particular rear-wheel drive pickup features an 8-foot bed and adds a second row for greater passenger capacity. The 2006 GMC Sierra 1500 Work Truck Extended Cab LB (Long Base) is a four-door model, though the rear doors reverse-open in conjunction with the front doors and rear legroom is a meager 33.7 inches. With two rows of split-folding benches, the Work Truck seats six. Front bucket seats are optional. The bed comes standard with tow hooks, but can be equipped with a trailer hitch for maximum towing capacity of 7800 pounds.

The extra interior space and longer bed are a result of 19 more inches in length and 14 inches in the wheelbase. The truck sits on a short and long arm front and solid live axle rear suspension. Getting the LB trim boosts engine power to a 5.3-liter V8 with 295-hp and 335 ft-lbs of torque at 4000 RPM. This engine is paired only with a 4-speed automatic. A flex fuel version is available, as is a 285-hp, 4.8 V8. Standard features are few, since this truck focuses on utility rather than comfort. A radio, intermittent wipers, tachometer, air conditioning, front power outlet, and tilt and power steering are the bare minimum, but you can add power features, cruise control, remote entry, a universal remote, extendable mirrors, and a CD player. If you want to dress up the exterior, chrome bumpers are also optional.

Dual front airbags feature passenger deactivation, but no side airbags are offered. The front disc and rear drum brakes come with 4-wheel ABS and electronic brakeforce distribution. The pickup earns three and four stars in frontal impact tests and four in rollovers. Automatic headlights and daytime running lights are also standard. Options add a locking rear differential and manual sliding rear window.

Adding 25 inches to both the length and the wheelbase of the 2006 GMC Sierra 1500 SL1 Extended Cab 4WD SB boosts passenger capacity to six in two rows of bench seats. The rear-wheel-drive pickup has four doors, though the rear reverse-hinged ones are not full-size and don't open independently of the front doors. Legroom in the second row is a mere 33.7 inches. The added length also requires the more powerful 4.8-liter, 285-hp V8, which gets 295 ft-lbs of torque at 4,000 RPM. It can be mated with a 4-speed automatic or 5-speed manual. Towing capacity maxes at 7,900 pounds, and fuel economy averages 16/20 mpg. Other engine choices include a 5.3-liter V8 and a 4.3-liter V6.

Riding on a front independent and solid live axle rear suspension, the 2006 Sierra 1500 SL1 Extended Cab comes equipped with cloth seats (instead of the vinyl found in Regular Cabs), cruise control, a CD player, intermittent wipers, a tachometer, tilt and power steering, and a front power outlet. It adds storage pockets in the front seatbacks. Bucket front seats are optional, along with full power features, extendable mirrors, and remote entry. An optional sliding rear window opens onto the 6.5-foot cargo bed, which comes with tow hooks. A trailer hitch can be added. Front disc and rear drum brakes come with 4-wheel ABS and electronic brakeforce distribution. Dual front airbags are standard, along with 17-inch wheels and automatic headlights. Available traction control adds more road grip. Other options include a locking rear differential and skid plates.

The SL2 trim line for the 2006 GMC Sierra 1500 comes only in a four-door Crew Cab setup. This features four regular-size doors opening onto two rows of seats. Rear legroom increases to 39 inches instead of the 33 in the Extended models. The Crew Cab has the same wheelbase and overall length as the Extended, which means the extra interior room crops off some inches on the pickup bed, which is only 5.8 feet long. This half-ton, rear-wheel-drive pickup comes standard with a 285-hp, 4.8-liter V8 and 4-speed automatic. A 5-speed manual is optional, along with a 5.3-liter, 295-hp V8.

The 2006 GMC Sierra 1500 SL2 Crew Cab rides on 17-inch wheels with all-season tires and features 4-wheel ABS brakes, front disc and rear drum brakes, dual front airbags with passenger deactivation, and automatic headlights. A locking rear differential, traction control, and skid plates can be added. The pickup earns three and four stars in crash tests. The SL2 ups the ante of the SL1 with standard power windows, locks, and mirrors, heated mirrors, and remote entry. These join cruise control, a CD player, tilt and power steering, a front power outlet, intermittent wipers, and a tachometer. Both front and rear benches split-fold, and bucket seats are available for the front row, along with an overhead storage console and rear sliding window. Tow hooks are standard in the cargo bed, and a trailer hitch is optional. Towing capacity maxes out at 5,700 pounds. An extra option with the SL2 is satellite radio.

Riding on a front independent and solid live axle rear suspension, the 2006 GMC Sierra 1500 SL1 Regular Cab 4WD features part-time four-wheel-drive power with automatic locking hubs, but only 8.4 inches of ground clearance. Skid plates and a locking rear differential cost extra. Under the hood sits a 4.8-liter, 285-hp V8 that puts out 295 ft-lbs of torque at 4,000 RPM. It comes standard with a 4-speed automatic, but a 5-speed manual is available. A 5.3-liter V8 is also available as a regular engine or a flex fuel E85 version. Fuel economy averages 15/19 mpg, and towing capacity tops out at 9,100 pounds.

The Regular Cab seats three in a front-row bench, and this particular trim comes with a 6.5-foot pickup bed with standard tow hooks and an optional trailer hitch. Power windows, locks, and mirrors are optional, but the 2006 Sierra 1500 SL1 does offer tilt and power steering, cruise control, a CD player, intermittent wipers, a tachometer, and a front power outlet. It earns only three and four stars in crash tests, due to a lack of side curtain airbags. Unlike the rear-wheel-drive trims, traction control is not optional. Dual front airbags, a front stabilizer bar, front-wheel disc and 4-wheel ABS brakes with electronic brakeforce distribution, automatic headlights, and 17-inch steel wheels with all-season tires are standard. The SL1 comes with several options, including remote entry, a sliding rear window, front bucket seats, and extendable side mirrors.

The 2006 GMC Sierra 1500 Work Truck Extended Cab 4WD SB clocks in at 230 inches, with a 143-inch wheelbase and 8.7 inches of ground clearance. One more number -- a 6.5-foot pickup bed. This trim features part-time 4WD with a center locking differential and both high and low-range gearing for off-road use. Skid plates and a locking rear differential can be added for better off-road handling. The four-door pickup rides on a short and long arm front and solid live axle rear suspension, getting around on 17-inch wheels with all-season tires. The rear doors are not full-sized and open in tandem with the front doors. Two rows of split-folding benches seat up to six, with 33.7 inches of legroom in the back.

Under the hood is a 285-hp, 4.8-liter V8 that puts out 295 ft-lbs of torque at 4000 RPM. It is paired with a 4-speed automatic. Upgrading to the optional 5.3-liter V8 gives you 295-hp and 335 ft-lbs and a flex fuel option. Towing power maxes out at 8700 pounds with the optional trailer hitch. Tow hooks come standard. Other standard features on the Sierra 1500 Work Truck Extended 4WD include air conditioning, tilt and power steering, a tachometer, a radio, vinyl seats, and a front power outlet. A CD player, power features, a manual sliding rear window, chrome bumpers, cloth upholstery, extendable mirrors, remote entry, and cruise control all cost extra.

To make room for the longer 8-foot cargo bed, the 2006 GMC Sierra 1500 SL1 Extended Cab LB adds 19 inches to its length and 14 to its wheelbase. The cargo bed comes with tow hooks, and a sliding rear window can be added. Two bench seats hold six people, though rear legroom is cramped. The second row is accessed only through half-doors that open toward the rear in conjunction with the front doors. Rear quarter windows open manually.

Under the hood of this rear-wheel-drive pickup rests a 4.8-liter V8 that gets 285 hp and 295 ft-lbs of torque. It can be replaced with either a 4.3-liter, 195-hp V6 (for a bit better gas mileage) or a 5.3-liter, 295-hp V8 in regular or flex fuel form. All are paired with either a 4-speed manual or 5-speed manual transmission.

Four-wheel ABS brakes, a front stabilizer bar, 17-inch wheels with all-season tires, dual front airbags, and automatic headlights are all standard safety features, but the Sierra earns only three and four stars in crash tests. Traction control is optional, along with skid plates and a rear locking differential. Side airbags are not offered. Cruise control, intermittent wipers, a CD player, tachometer, front power outlet, front console storage, cloth seats, and tilt and power steering are standard creature comforts, with the option to add power windows, locks, and extendable mirrors, remote entry, bucket front seats, and privacy glass.

The two-door 2006 GMC Sierra 1500 SL1 Regular Cab 4WD LB offers a long 8-foot pickup bed for more cargo space. The part-time 4WD features automatic locking hubs and can be equipped with a locking rear differential. Skid plates and 8.4 inches of ground clearance help with off-road power, as does the standard 285-hp, 4.8-liter V8 with 295 ft-lbs of torque. Available transmissions include a 4-speed automatic and 5-speed manual. An optional trailer hitch allows you to tow up to 8,900 pounds. More power is available in the 5.3-liter V8 engine, which is also offered in a flex fuel version.

The 2006 GMC Sierra 1500 SL1 Regular Cab 4WD LB seats three in one row, with 41 inches of front legroom. Bucket front seats can replace the standard bench. Minimally equipped, the pickup features a CD player, cruise control, intermittent wipers, a tachometer, vinyl seats, front cupholders, and a front power outlet. Power accessories cost more, as do remote entry, extendable mirrors, and a sliding rear window. The Sierra 1500 earns only three and four stars in frontal impact tests. It comes equipped with four-wheel ABS, front disc and rear drum brakes, dual front airbags, a front stabilizer bar, and 17-inch wheels with all-season tires. Daytime running lights and automatic headlights are also standard.

With ten more inches in overall length and wheelbase, the 2006 GMC Sierra 1500 SLE1 Extended Cab SB sports a 6.5-foot-long cargo bed. The half-ton pickup comes with four doors, though the rear ones open toward the back and in conjunction with the front doors. Two rows of split-folding bench seats fit six passengers, but front bucket seats can be substituted. Rear legroom is a tiny 33.7 inches. The rear-wheel-drive SLE1 sits on a short and long arm front and solid live axle rear suspension and rides on 17-inch steel wheels with all-season tires. Alloy wheels are optional, as are larger 20-inch wheels.

A 4.8-liter, 285-hp V8 and 4-speed automatic that get around 16/19 mpg can tow nearly 10,000 pounds. A more eco-friendly flex fuel 5.3-liter V8 is available, along with a powerful 345-hp 6.0-liter V8 and heavy duty suspension, for extra hauling capacity. Earning only three and four stars in frontal impact and rollover tests, the pickup comes standard with dual front airbags with passenger airbag sensors, 4-wheel ABS with electronic brakeforce distribution, and a front stabilizer bar. Also on hand are automatic headlights, foglights, and an auto-dimming rearview mirror. Adding more security are optional traction control, OnStar, skid plates, a locking rear differential, and mirrors with turn signals.

Driver comfort is taken care of by a full power setup, remote entry, cruise control, leather trim, and a CD player. A tachometer, front power outlet, intermittent wipers, tilt and power steering, and a compass and temperature display provide extra convenience. A long list of options add leather seats, a power driver's seat with memory settings, a trip computer, wheel-mounted audio controls, satellite radio, and a sliding rear window.

This rear-wheel-drive pickup seats six in two rows, with four full-size doors and a 5.8-foot cargo bed. Rear legroom expands six inches from that in the Extended models. The truck rides on a short and long arm front and solid live axle rear suspension. Under the hood is a 4.8-liter V8 that delivers 285-hp and 295 ft-lbs of torque. It's matched to a 4-speed automatic, but a 5-speed manual can be substituted, along with a 295-hp, 5.3-liter V8 or a 195-hp, 4.3-liter V6.

The LB in the 2006 GMC Sierra 1500 Work Truck Extended Cab 4WD LB signifies the 14 extra inches in the wheelbase, which makes room for a longer 8-foot pickup bed. The 4WD in its title refers to the part-time system that can be taken off-road, thanks to both high and low-range gearing. In the Work Truck, 17-inch wheels with all-season tires are standard, as is 8.7 inches of ground clearance. You may want to add the optional skid plates and locking rear differential. The longer bed also gets more power with the larger 5.3-liter V8 and 4-speed automatic (a flex fuel version is optional). These deliver 295-hp and 335 ft-lbs of torque, with 8500 pounds of towing capacity and 16/20 mpg. A 285-hp 4.8 V8 is also available. Tow hooks are standard, with the option to add a trailer hitch.

The pickup seats six in two rows of split-folding benches, though front bucket seats can be substituted. Rear legroom is cramped, and though it features four doors, the rear ones do not open separately from the front ones. A manual sliding rear window costs extra. Cupholders reside only up front, along with a power outlet. A radio, air conditioning, tilt and power steering, vinyl seats, intermittent wipers, and a tachometer are also standard. You can dress things up with the optional power windows, locks, and power extendable mirrors. Also available are a CD player, remote entry, cruise control, cloth seats, and chrome bumpers.

The front disc and rear drum brakes accompany 4-wheel ABS with electronic brakeforce distribution. Dual front airbags with passenger deactivation are standard, but side airbags not an option on the Sierra 1500. Automatic headlights, halogen lamps, and daytime running lights round out the lighting equipment. This pickup earns three and four stars in frontal impact tests and four in rollover tests.

This rear-wheel-drive pickup trim features two rows of seats, accessed via reverse-hinged quarter rear doors.

The 4WD system in the 2006 GMC Sierra 1500 SLE1 Regular Cab 4WD SB moves you up to an on-demand full-time system (Autotrac) that comes with automatic locking hubs and a center differential. Equipped with high- and low-range gearing, this half-ton pickup is a capable off-roader as well, and the optional skid plates help with its 8.4 inches of ground clearance. A locking rear differential is also optional.

The 2006 Sierra 1500 SLE1 Regular 4WD SB seats three in one front-row bench, though bucket seats can be substituted. The cargo bed measures 6.5 feet and comes with tow hooks. Towing capacity reaches 9,100 pounds with the 4.8-liter, 285-hp V8 and 4-speed automatic, though a flex fuel 295-hp, 5.3-liter V8 is also available. The pickup rides on a short and long arm front and solid live axle rear suspension. A front stabilizer bar, dual front airbags with passenger deactivation, front disc and rear drum brakes, and 4-wheel ABS provide the four-star safety features. Automatic headlights, an auto-dimming rearview mirror, and foglights are included. Options add mirrors with turn signals and OnStar.

The SLE1 is where luxury starts to make an appearance, with standard power features, remote entry, heated extendable mirrors, leather steering-wheel trim, cruise control, and a CD player with radio data. Intermittent wipers, a tachometer, a front power outlet, tilt and power steering, and a temperature display add extra convenience. An array of options include a power driver's seat with memory settings, satellite radio, wheel-mounted audio controls, a sliding rear window, and a trip computer.

An extra 19 inches in length and 14 inches in wheelbase permit a longer 8-foot cargo bed on the 2006 GMC Sierra 1500 SLE1 Extended Cab LB. The rear-wheel-drive pickup seats six in two rows that split-fold, and the front bench can be replaced with bucket seats. The longer bed requires a 295-hp, 5.3-liter V8 that delivers 335 ft-lbs of torque at 4,000 RPM and can tow 8,000 pounds. It is paired with a 4-speed automatic. The other engine option is a 285-hp, 4.8-liter V8. Fuel economy sits in the mid-teens.

The pickup bed comes with tow hooks and the option to add a trailer hitch. The SLE1 comes standard with full power features, remote entry, cruise control, heated mirrors, leather trim, a CD player, front power outlet and cupholders, tilt and power steering, a security system, a temperature readout and compass, and intermittent wipers. Extended Cabs feature four doors, though the smaller rear doors do not open independently of the front doors. For those using the truck for comfort, along with utility, you can add a power driver's seat with memory settings, leather upholstery, a trip computer, wheel-mounted audio controls, and satellite radio.

On the safety front, the Sierra SLE1 Extended LB rates average, with standard 4-wheel ABS brakes and electronic brakeforce distribution, dual front airbags, 17-inch wheels with all-season tires (alloy available), and a front stabilizer bar. Side curtain bags are not offered, but traction control is, along with a locking rear differential, OnStar, mirrors with turn signals, and skid plates. Foglights, daytime running lights, and automatic headlights are all standard.

By day a work truck, the 2006 GMC Sierra 1500 SLE1 Regular Cab 4WD LB has a surprising number of high-end comfort features for a pickup. This half-ton model features on-demand 4WD with low-range gearing, a center differential, 8.4 inches of ground clearance, and 17-inch steel wheels with all-season tires. Able to perform off-road, it can also be outfitted with a heavy-duty suspension and skid plates. A 4.8-liter V8 gets 285 hp and 295 ft-lbs of torque at 4,000 RPM, with 16/19 mpg. A 4-speed automatic is the only transmission (no 5-speed manual option). Also offered is a 5.3-liter, 295-hp V8. It can tow 8,900 pounds with the optional trailer hitch. Tow hooks are standard.

The Regular Cab means one row of seats, but 19 more inches of overall length allow for an 8-foot cargo bed. Front passengers are treated to power windows, locks, and heated extendable mirrors, as well as remote entry, cruise control, a CD player, leather trim, and a front power outlet.

Convenience features include a trip computer on the dash, along with a compass and temperature display, a tachometer, and intermittent wipers. A security system is also in place. For a bit more flash, you can add satellite radio with audio controls on the steering wheel, privacy glass, and a power driver's seat with memory settings. Making things fancy on the outside are a chrome grille and bumpers, with the option to add alloy wheels.

Upgrading from the SL1, the safety profile adds standard foglights and an auto-dimming rearview mirror, plus more options such as OnStar and mirrors with turn signals. An average crash test rating (four and three stars) comes from the minimum safety features. These include dual front airbags, 4-wheel ABS with electronic brakeforce distribution, a front stabilizer bar, and automatic headlights. Traction control is not offered with the 4WD models.

The part-time on-demand 4WD system adds some rugged performance capability to the 2006 GMC Sierra 1500 SL1 Extended Cab 4WD SB. Low-range gearing lets you take it off-road, and skid plates can be added for extra protection, since the pickup comes with 8.4 inches of ground clearance. Standard power for this pickup comes from a 285-hp, 4.8-liter V8 with 295 ft-lbs of torque at 4,000 RPM. You can substitute a 4.3-liter V6 or a 5.3-liter V8 with flex fuel option. All engines are paired with a 4-speed automatic or 5-speed manual.

The Extended Cab seats up to six in two rows, with a spacious 41 inches of legroom up front, but only 33.7 in the back. Front bucket seats can replace the front split-folding bench. The cargo bed is 6.5 feet long and comes with tow hooks. The optional trailer hitch enables towing up to 8,700 pounds. Tilt and power steering, cruise control, a CD player, intermittent wipers, vinyl seats, a front power outlet, and a tachometer are all standard.

On the safety front, you get automatic locking hubs, a front stabilizer bar, 4-wheel ABS brakes with electronic brakeforce distribution, 17-inch wheels with all-season tires, and dual front airbags. Daytime running lights and automatic headlights are also standard. Traction control is not offered on 4WD models, but you can add a locking rear differential. Other options include power windows, locks, and extendable mirrors as well as remote entry and a sliding rear window.

The only major upgrades you get when you move up to the 2006 GMC Sierra 1500 SLE2 Extended Cab 5.8 SB are a power driver's seat and a larger 5.3-liter V8 that gets 295 hp and 335 ft-lbs of torque at 4,000 RPM. It's paired with a 4-speed automatic, and a flex fuel version is available. It also offers more options, such as a power sunroof, a CD changer and rear audio controls, an adjustable suspension, and regenerative braking.

The Extended Cab seats six in two bench rows that split-fold and come with folding armrests. At only 220 inches long (compared to a standard Extended Cab's 230), the rear-wheel-drive pickup features a 5.8-foot cargo bed. Tow hooks are standard, and a trailer hitch is optional (it can tow around 8,000 pounds). Full power features, remote entry, a CD player, cruise control, tilt and power steering, intermittent wipers, a front power outlet, a tachometer, leather wheel trim, and a compass and temperature display are all standard. Options add wheel-mounted audio controls, a trip computer, automatic climate control, leather seats, memory settings for the driver's seat, and a manual sliding rear window.

The SLE2 still earns only three and four stars in crash tests. Dual front airbags feature passenger sensors, but no curtain bags are offered. 4-wheel ABS comes with electronic brakeforce distribution. The 17-inch steel wheels with all-season tires can be replaced with alloy wheels and larger 20-inch wheels. At nighttime, the standard foglights, automatic headlights, and auto-dimming rearview mirror come in handy. Options add the auto-dimming feature to the side mirrors, along with OnStar, skid plates, and mirrors with turn signals.

The on-demand 4WD system in the 2006 GMC Sierra 1500 SL2 Crew Cab 4WD is an Autotrac setup, which automatically distributes torque where needed. It features high- and low-range gear settings for off-road performance and comes with automatic locking hubs, 8.4 inches of ground clearance, and off-road tires on its 17-inch wheels. Skid plates cost extra. Power comes from a 285-hp 4.8-liter V6 that offers 295 ft-lbs of torque at 4,000 RPM, matched to a 4-speed automatic. Towing capacity is 6,400 pounds. A 5.3-liter V8 or a 4.3-liter V6 is also available, with a 5-speed manual transmission.

The SL2 Crew Cab seats six in two full-size rows which both split-fold. Forty inches of front and rear legroom are passenger-friendly, though the cargo bed is only 5.8 feet long. It comes with tow hooks and an optional trailer hitch. Upgraded cloth seats, full power features, and remote entry distinguish it from the SL1. Other standard equipment includes cruise control, a CD player, tilt and power steering, a tachometer, and intermittent wipers. Satellite radio is optional. Chrome bumpers and a chrome grille boost the star power of the Sierra.

Safety features are few, and the Sierra ranks only average in crash tests. Dual front airbags with passenger deactivation, 4-wheel ABS with electronic brakeforce distribution, a front stabilizer bar, and automatic headlights are about it. Traction control and side curtain airbags are not offered. The pickup employs a short and long arm front independent and solid live axle rear suspension.

The 2006 GMC Sierra 1500 SLE2 Extended Cab SB measures 230 inches in length, with a 143-inch wheelbase, meaning the cargo bed expands to 6.5 feet long in this trim. The rear-wheel-drive, half-ton pickup is powered by a 295-hp, 5.3-liter V8 and 4-speed automatic, but a 6.0-liter, 345-hp V8 is available, along with a flex fuel version of the 5.3-liter V8. Fuel economy averages 16/19 mpg. The pickup rides on a short and long arm front and solid live axle rear suspension and uses 17-inch steel wheels with all-season tires. Larger 20-inch wheels are available.

The bed comes with tow hooks, but a trailer hitch is an extra feature. Fully equipped, the 2006 Sierra 1500 SLE2 Extended Cab SB can tow 10,400 pounds. It has two rows of seats, though the rear seat is limited and has only 33.7 inches of legroom. The rear passenger doors are undersized and open in conjunction with the front doors. Full power features include a power driver's seat, remote entry, heated extendable mirrors, a CD player, cruise control, and intermittent wipers. Leather steering-wheel trim, a front power outlet, a tachometer, and a temperature display and compass are also standard. Options add audio controls in the backseat and on the wheel, satellite radio, leather upholstery, memory settings for the driver's seat, automatic climate control, a CD changer, and a power sunroof.

Safety equipment is fairly minimal, but this Sierra does feature dual front airbags with passenger sensors, 4-wheel ABS brakes with electronic brakeforce distribution, a front stabilizer bar, automatic headlights, foglights, and an auto-dimming rearview mirror. Traction control is available as an option. Auto-dimming side mirrors also cost extra, as does an adjustable suspension, regenerative braking, OnStar, mirrors with turn signals, a locking rear differential, and skid plates.

The first thing you'll notice about the 2006 GMC Sierra 1500 SLE1 Crew Cab is its four full-size doors and extra legroom for backseat passengers. Legroom increases from 33.7 inches in the Extended Cabs to 39 inches in the Crew. What suffers is the cargo bed, which comes only in the 5.8-foot length. The 6.5- and 8-foot beds are not available with the Crew Cab. This rear-wheel-drive pickup also gets the strong 5.3-liter V8 that produces 285-hp and 335 ft-lbs of torque at 4,000 RPM. It is paired with a 4-speed automatic and can tow more than 10,000 pounds with the optional trailer hitch (tow hooks are standard). A 6.0-liter, 345-hp V8 is available.

Otherwise, the 2006 Sierra 1500 SLE1 Crew Cab resembles the Extended Cab trims in terms of features. Power windows, locks, and extendable heated mirrors, cruise control, a CD player with radio data, leather steering-wheel trim, remote entry, intermittent wipers, a front power outlet, a tachometer, tilt and power steering, and a compass and temperature display are all standard. Add-ons include a power driver's seat with memory settings, wheel-mounted audio controls, satellite radio, a trip computer, and leather seats.

In terms of safety, the pickup ranks average. Dual front airbags with passenger deactivation are standard, but no side curtain bags are available. Front disc and rear drum brakes are complemented by 4-wheel ABS and electronic brakeforce distribution. 17-inch wheels are standard, with the option to add 20-inch alloy ones. Automatic headlights and foglights help at night. Available options include a locking rear differential, skid plates, traction control, mirrors with turn signals, and OnStar.

The 2006 GMC Sierra 1500 SL1 Extended Cab 4WD LB features four doors (though the rear doors are smaller, reverse-hinged, and don't open independently from the front doors), two rows of seats, and an 8-foot cargo bed, thanks to almost 20 more inches in overall length than Regular Cab trims. Tow hooks are standard, with the option to add a trailer hitch. This trim also adds part-time four-wheel drive with automatic locking hubs and low-range gearing for off-road performance. A locking rear differential is optional. The pickup rides on a front independent and solid live axle rear suspension, with 17-inch wheels and all-season tires, and 8.4 inches of ground clearance. Skid plates are available.

Powering this pickup is a 285-hp, 4.8-liter V8 with 295 ft-lbs of torque. A 4-speed automatic or 5-speed manual are the transmission options. A 295-hp, 5.3-liter V8 and a 195-hp, 4.3-liter V6 are also available. Fuel economy averages in the mid- to high teens, and towing capacity tops out at 8,500 pounds.

The 2006 Sierra 1500 SL1 Extended gets three and four stars in frontal impact tests. It comes standard with dual front airbags, front disc and rear drum brakes, 4-wheel ABS, and automatic headlights. Side curtain bags and traction control are not options. A chrome grille and bumpers dress up the exterior. Inside, drivers are treated to tilt and power steering, a CD player, cruise control, a front power outlet, intermittent wipers, and a tachometer. Rear passengers get seatback pockets and a cramped 33.7 inches of legroom. A sliding rear window that leads to the bed is optional. Other add-ons include full power features, remote entry, privacy glass, cloth seats, and extendable side mirrors.

A larger overall length and wheelbase create a longer 8-foot cargo bed in this rear-wheel-drive, half-ton pickup. The 2006 GMC Sierra 1500 SLE2 Extended Cab LB comes with a stronger engine than the SLE1 - a 5.3-liter V8 with 295 hp and 335 ft-lbs of torque at 4,000 RPM. It's paired with a 4-speed automatic and can tow nearly 8,000 pounds when equipped with the optional trailer hitch. Tow hooks come standard. Also added with the SLE2 is a power driver's seat, though memory settings cost extra.

The pickup seats six in two rows, though the second row is somewhat cramped and accessed through its own set of smaller, reverse-hinged rear doors. Both rows split-fold and feature storage compartments. A full power setup includes remote entry and cruise control. A CD player is standard, with the option to add satellite radio and both wheel-mounted and rear audio controls. Intermittent wipers, a security system, a temperature display and compass, a front power outlet, heated extendable mirrors, and leather steering-wheel trim are also part of the SLE2 package. Leather upholstery, a sunroof, and a trip computer are optional.

This trim earns only average crash test scores, in part due to its lack of available side curtain airbags. It does come equipped with dual front bags with passenger sensors, 4-wheel ABS, a front stabilizer bar, 17-inch steel wheels with all-season tires (alloy wheels optional), tilt and power steering, automatic headlights, foglights, and an auto-dimming rearview mirror. This latter function can be added to the side mirrors. Other safety options include OnStar, traction control, an adjustable suspension, and turn signals incorporated into the mirrors.
