2007 GMC Sierra Classic 1500: Overview

Vehicle Highlights

GMC's version of the Chevrolet Silverado carries over unchanged for 2007 as the Sierra 1500 Classic. Like the Silverado Classic, it's based a design introduced for 1999. The next-generation of both trucks debuted in calendar 2006, and are sold alongside the Classics, also as 2007 models.

This report covers the half-ton Sierra 1500 and 1500HD Classics. They come in regular, extended, and Crew Cab versions. Extendeds have rear-hinged back doors that don't open independently of the fronts. Front seating is via a bench or buckets. Extendeds and Crews include a three-person rear bench seat. Regulars and extendeds offer 6.6- and 8-ft cargo beds. Extendeds and Crew Cabs are available with a 5.8-ft bed.

Trim levels ascend from Work to Denali Crew Cab. Denali, which also gets the Classic suffix, has all-wheel drive without low-range gearing. Other Sierras are available with rear-wheel drive or one of two 4WD systems. The basic 4WD system should not be left engaged on dry pavement; GM's Autotrac can. Both include low-range gearing. Engine choices range from a 195-hp V6 to a 345-hp V8, depending on model and option selection. Same for available manual and automatic transmissions.

Sierra is also available as a Hybrid model. It's a 6.5-ft-bed extended cab with a V8 and 2WD or 4WD. It uses an electric motor to provide 120-volt power for electrical accessories. The electric motor does not propel the vehicle. On-board systems charge its batteries; no plug-in charging is necessary. Sierra 1500 Classic's performance and accommodations mirror those of comparable Silverado 1500 Classics.

COMPETITION

Consumer Guide® Automotive places each vehicle into one of 17 classes based on size, price, and market position. Large Pickup Trucks are traditionally the vehicle of choice for heavy-duty hauling and towing. They offer an array of cab styles and bed lengths and usually feature powerful V8 or diesel engines. For personal use, consider light-duty 1/2-ton models. For heavy-duty or commercial use, consider 3/4- or 1-ton models.
