The Silverado 1500 Classic shares its design with the GMC Sierra 1500 Classic and both carry over unchanged for 2007. They're based on a design introduced for 1999. The next-generation of both trucks debuted in late 2006, and is sold alongside the Classics, also as 2007 models.

This report covers the half-ton 1500-series Silverado Classic. It comes in regular, extended, and Crew Cab models. Extendeds have rear-hinged back doors that don't open independently of the fronts. Extendeds and Crews include a three-person rear bench seat and offer front buckets or a bench. Crews have a 5.8-ft Fleetside cargo bed. The others offer Fleetside beds of 6.6 and 8.0 ft, or a 6.6-ft Sportside flare-fender bed. Extendeds are also available as the high-performance SS model with a 6.5-ft Fleetside bed and special tires and trim. Available engines, depending on cab/bed configuration, are a 195-hp V6 and V8s of 285, 295, and 310 hp. SS uses a 345-hp V8. Also available is the 1500HD Crew Cab with a 300-hp V8.

Regular cabs are available with manual or automatic transmission, but automatic is standard on most Silverados. All models come with rear-wheel drive. All but SS are available with 4-wheel drive. There are two 4WD systems: a basic setup that should not be left engaged on dry pavement, and GM's Autotrac that can. Both include low-range gearing. ABS is standard; 2WD models are available with traction control.

Silverado 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.
