This review focuses on the Sierra 1500 models. Although nominally classified as light duty or half-ton" trucks, the 1500s offer payloads ranging from 1,215 to 2,040 pounds, and tow ratings from 4,100 up to 9,000 pounds, depending on equipment. That's all the truck most consumers will ever need.
Engine choices include a 4.3-liter V6, 4.8-liter V8, and 5.3-liter V8. New for 2005 is an all-aluminum version of the 5.3-liter, used exclusively in four-wheel-drive Extended Cab Standard Box models. Five-speed manual and four-speed automatic transmissions are offered.
Consumers with exceptional needs may find a reasonable compromise in the 1500HD, which returns for 2005. Available only as a Crew Cab with a 6-foot-6-inch bed (instead of the standard 1500 Crew Cab's 5-foot-8-inch bed), the 1500HD hauls 3,073 pounds with 2WD, 2,766 pounds with 4WD, and tows 10,200 pounds. Power is provided by the same 6.0-liter V8 that's used in the 2500HD/3500; but the 1500HD should ride more smoothly than the heavy-duty trucks.
Base models come with ABS, air conditioning, cruise control, AM/FM/CD audio, an attractive chrome grille molding, a chrome rear step bumper, and 17-inch chromed steel wheels. Carpeting and cloth seats are also standard. Regular and Extended Cabs are available, but not the Crew Cab, Base prices range from $21,045 to $31,270.
The W/T (Work Truck) model deletes the CD player, chrome, cruise control and carpeting. These plane-Jane trucks are aimed at commercial and municipal fleets, with prices ranging from $18,770 to $29,540.
SLE trim adds fog lamps; power windows, mirrors, and door locks; a leather-wrapped steering wheel; overhead console; and other amenities. Leather upholstery is optional. The 4.8-liter V8 and automatic transmission are standard on Regular and Extended Cabs; Crew Cabs come with the 5.3 and automatic. Prices range from $25,755 to $34,140.
SLT trim, available on Extended Cabs and Crew Cabs, adds automatic dual-zone air conditioning, leather upholstery, power-adjustable bucket seats with heat and memory, floor console, heated outside mirrors, new Gen6 OnStar telecommunications and 17-inch aluminum wheels. The 5.3-liter V8 is standard, with a higher-performing, all-aluminum 5.3 in 4WD Extended Cabs. Prices range from $33,270 to $38,205.
Sierra Denali ($41,735), the flagship of the fleet, packs a 345-horsepower version of the 6.0-liter V8, along with automatic transmission, vacuum-boosted four-wheel-disc brakes and an exclusive, sophisticated full-time all-wheel-drive system. Denali comes with tone-on-tone leather, extra sound deadening, a Bose audio system with separate controls for rear-seat passengers, and other exclusive amenities. It's equipped with steering wheel controls for the audio system, Gen6 OnStar, trip computer, and other programmable functions. A power sunroof is available.
A Sierra Hybrid is available in some states and, with its unique starter/generator combined with its Vortec 5300 5.3L V8, offers up to a 10 percent improvement in fuel economy while delivering the same 295 horsepower and 335 pound-feet of torque as any other Sierra with the 5300 engine.
Quadrasteer electronically controlled four-wheel steering is available on Sierra 1500 standard-bed Extended Cabs with 4WD, 1500HD Crew Cabs with 2WD or 4WD, and on 2500HD Crew Cabs. Quadrasteer reduces Sierra's curb-to-curb turning diameter by 26 percent and enhances high-speed stability. It comes packaged ($1,995) with a limited-slip differential, heavy-duty brakes and clearance lights."
