The 2008 GMC Sierra 1500 is loaded with styling and equipment upgrades that make it a cut above a Chevrolet. It's available as a 2- to 3-passenger 2-door regular cab, a 4- to 5-passenger extended cab or a 5- to 6-passenger 4-door crew cab. The extended cab offers two full-size front doors and a pair of rear-hinged half-length suicide rear doors with a fold-down rear seat. The regular cabs come with a standard 6.5-foot bed or a long 8-foot bed. Extended cabs offer a short 5.7-foot bed, a standard 6.5-foot bed and a long 8-foot bed. With two seat rows, the crew cab comes exclusively with the 5.7-foot bed. Both rear-wheel drive and 4-wheel drive are offered, and 4-wheel anti-lock brakes are standard. Safety gear includes dual-stage front airbags and a warning for low tire pressure, as well as optional stability control and overhead airbags. OnStar and SiriusXM radio are standard. Maximum towing capacity is 10,500 pounds. Sierra All Terrain debuts for 2008 with Rancho off-road shocks, heavy-duty towing, 18-inch chrome wheels and unique trim.

Navigation, a power sunroof, 20-in alloy wheels, automatic climate control, power adjustable pedals, remote start, rear park assist, a power-sliding rear window, rear-seat entertainment, cargo management, rain-sensing wipers, heated windshield washers and power heated leather front seats with memory are available on the Denali and upper trims. New for 2008 is an optional integrated brake controller.

What We Like

Interior quality; dual glove boxes on Work Truck and SLE; OnStar; available stability control; V8 performance

What We Don't

No manual transmission; small air-conditioning and audio buttons on SLT and Denali

Fuel Economy & Engine Specs

2008 GMC Sierra 1500 regular and extended cabs are available with a 4.3-liter V6 that makes 195 horsepower and 260 lb-ft of torque. Two-wheel-drive (2WD) versions are rated by the Environmental Protection Agency (EPA) at 15 miles per gallon in the city and 20 mpg on the highway, while 4-wheel-drive versions get a 14 mpg city/18 mpg hwy rating. All use regular unleaded and a 4-speed automatic transmission.

A 4.8-liter V8 is available on regular, extended and crew cabs. It develops 295 hp and 305 lb-ft of torque. EPA ratings are 14 mpg city/19 mpg hwy for the 2-wheel-drive version and 14 mpg city/18 mpg hwy on the 4-wheel-drive version.

The 5.3-liter V8 is available on regular, extended and crew cabs, and some versions have E85 flex-fuel capability. All generate 315 hp and 338 lb-ft of torque, and EPA ratings are 15 mpg city/20 mpg hwy for 2-wheel-drive models and 14 mpg city/19 mpg hwy for 4-wheel-drive models. Active Fuel Management (AFM) idles four cylinders during light cruising to boost fuel economy.

SLE and SLT models can option up to a 6.0-liter V8 with 367 hp and 375 lb-ft of torque. It's not available on regular cabs. EPA ratings are 13 mpg city/18 mpg hwy for 2-wheel-drive models and 13 mpg city/17 mpg hwy on 4-wheel-drive models. The 6.0-liter V8 uses fuel-saving AFM, as well.

Sierra Denali comes standard with an all-aluminum 6.2-liter V8 with 403 hp and 417 lb-ft of torque. It's teamed with a 6-speed automatic. Running premium unleaded, it's rated at 12 mpg city/19 mpg hwy with 2WD and 12 mpg city/18 mpg hwy with all-wheel drive.

Standard Features & Options

The Sierra 1500 comes in WT, SL, SLE, SLT and Denali trims.

The WT (Work Truck) features vinyl flooring, 245/70 tires on 17-in steel wheels, a 4-speaker AM/FM radio, a cloth 40/20/40-split front bench seat, dual glove boxes, intermittent wipers, a tilt steering wheel, auto headlamps, a front-center storage armrest and manual-folding outside mirrors.

The SL is crew-cab only and comes with a 4.8-liter V8, air conditioning, power windows, mirrors and door locks and remote keyless entry.

The SLE trim adds carpeting, upgraded cloth seats, air conditioning, fog lamps, cruise control, a CD/MP3 player, remote keyless entry, a rear-window defogger, an auto-dimming inside mirror, a compass, an outside-temperature gauge and power windows, mirrors and door locks. An SLE2 equipment group adds automatic dual-zone air conditioning, power front seats, 17-in alloy wheels and a 6-speaker stereo with steering-wheel audio controls.

The SLT brings a Yukon SUV-style dashboard, leather seats, heated power front seats, a memory driver's seat, a chrome front bumper, a 7-speaker Bose stereo with a 6-disc CD changer, power-folding turn-signal mirrors, heated windshield washers, a garage-door opener and rain-sensing wipers.

The Sierra Denali adds a chrome grille, a 6.2-liter V8, a 6-speed automatic, 4-wheel discs, stability control, polished 18-in alloys, power adjustable pedals, overhead airbags, remote starting, rear park assist, the EZ-Lift tailgate, a limited-slip differential, a trailer hitch and a wood- and leather-wrapped steering wheel.

The Z71 package adds off-road suspension, 265/65-18 on-/off-road tires on alloy wheels, increased ground clearance, wheel flares and monotube shocks.

Pricing

Used full-size pickups retain their value because the useful service life is typically 200,000 miles or longer. Four-door crew cabs are the priciest, since they have the most enclosed space and four conventional doors. Four-wheel-drive models exact a premium, especially in northern climates with snow.

Recalls

The National Highway Traffic Safety Administration (NHTSA) announced the following recall for the 2008 Sierra 1500:

A short circuit in the heated windshield-wiper washer system may create a fire risk.

Recall repairs are required by law even if the vehicle is out of warranty. Your dealer can check to see if the repairs were performed and, if not, will fix the car at no charge to you.

Safety Ratings & Warranties

NHTSA gave the 2008 Sierra 1500 five stars for frontal- and side-impact protection and four for rollover performance.

The Insurance Institute for Highway Safety (IIHS) rated the 2008 Sierra crew cab as Good for moderate-overlap front impacts, Poor for side impacts (with or without overhead airbags) and Acceptable for head-restraint and seat crash performance. IIHS did not rate the regular-cab or extended-cab Sierras.

General Motors offered a 3-year/36,000-mile bumper-to-bumper warranty, a 5-year/100,000-mile powertrain warranty with roadside assistance and a 6-year/100,000-mile corrosion-perforation warranty.

No certified pre-owned 2008 Sierra 1500s are available, as GMC certified pre-owned vehicles must be 5 years old or less.

Other Cars to Consider

2008 Ford F-150 -- The top-selling vehicle in the U.S. features seven trims (including lux King Ranch and Harley-Davidson editions), a 202-hp 4.2-liter V6, a 248-hp 4.6-liter V8 and a 300-hp flex-fuel 5.4-liter V8. Maximum tow capacity is 10,500 pounds.

2008 Dodge RAM 1500 -- The big Dodge offers regular, Quad or super-roomy Mega Cab body styles and a 215-hp 3.7-liter V6, a new 310-hp flex-fuel 4.7-liter V8 or a 345-hp 5.7-liter HEMI V8. Maximum tow capacity is 9,100 pounds.

Autotrader's Advice

We'd recommend an extended or crew cab with the 5.3-liter V8 and the SLE trim or higher to get power windows, power door locks, power mirrors and cruise control. Look for lower-mileage examples that have seen obvious care and maintenance. Avoid modified trucks if possible, and look for a vehicle with a Carfax or equivalent vehicle-history report. Finally, make sure that all applicable safety recalls have been performed.
