The Sierra aims to present itself as a more upscale, premium version of the Chevrolet Silverado—but beneath the GMC’s sculpted sheet metal and nicer trim, the two are basically the same. The base engine is a 285-hp V-6; optional engines include a 355-hp V-8 and a 420-hp V-8. The maximum payload is 2260 lb; maximum towing is 12,000 lb. Regular cabs offer 6.5-ft or 8-ft boxes; double cabs have a 6.5-ft box and crew cabs offer a 5’8” box or a 6.5-ft box. All-wheel drive is optional for all models.
