The Sierra is GMC's full-sized truck, which aside from styling and package differences is nearly identical to the Chevrolet Silverado. The Sierra 1500 series encompasses a broad range of cab styles, bed lengths, powertrains, and towing capabilities. Trim levels range from the base models to the luxury Denali models. The midrange SLE and SLT models offer most of features truck buyers are looking for. The SLE equips cloth seats and the SLT has leather bucket seats. Powertrain choices are broad ranging from a base V6 engine to a brawny 6.2l V8 for increased towing or bragging rights. Pricing is competitive with other trucks, but bigger engines and options add up quickly. Any truck shopper looking to tow should pay careful attention to the option list to make sure their truck is properly equipped for the job.

What Changed:

GM's full-sized trucks are all-new for 2014. Although the trucks have been restyled they are in large part the same size as their predecessors. Extended cab models now feature four front-hinged doors and crew cab models have a much larger interior. Powertrain choices include a 4.3l V6, 5.3l V8, and a 6.2l V8. Trim levels are largely unchanged, with base, SLE, and SLT trim levels.
