What's New For 2015?

The Sierra WT's only change for 2015 is the addition of GM's latest OnStar system, which offers 4G LTE Wi-Fi capability.

What We Like

Attractive pricing; very capable; tough workhorse for tough jobs

What We Don't

Few features; bare-bones interior; some items look and feel cheap

Overview

The 2015 GMC Sierra is a full-size truck offered with several trims, including the base-level Sierra model and the high-end Sierra Denali. This overview covers the base-level 2015 GMC Sierra, also known as the Work Truck, which is aimed at commercial buyers looking for a no-frills vehicle that can get a job done.

In other words, don't expect the base-level Sierra to come with many features. The pickup has basics such as air conditioning, power locks and cruise control -- but you won't find a CD player, keyless entry, Bluetooth or even GM's OnStar system, which is standard in the vast majority of the brand's models.

Fortunately, base-level Sierra models offer a few options for drivers who want to upgrade their trucks. SiriusXM satellite radio is optional, as is a center-mounted touchscreen. Crew Cab models offer navigation, and shoppers can add alloy wheels, power windows and GM's OnStar telematics system, depending on the body style.

Of course, the lack of standard equipment has an upside: reasonable pricing. The least-expensive base-level Sierra, a regular cab model with a regular-length bed, starts around $27,900 with shipping. Double Cab models are around $32,000, while Crew Cab variants start around $36,600. That's on par with base-level versions of rivals such as the Ford F-150 and RAM 1500.

For the powertrain, base-level Sierra models start with a 4.3-liter V6. It offers 285 horsepower and 305 lb-ft of torque, and returns 18 miles per gallon in the city and 24 mpg on the highway with 2-wheel drive or 17 mpg city/22 mpg hwy with 4-wheel drive. Optional for around $1,100 extra is a new 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. That engine returns 16 mpg city/23 mpg hwy with 2-wheel drive or 16 mpg city/22 mpg hwy with 4-wheel drive.

If you don't want any bells and whistles, the base-level 2015 GMC Sierra is a great truck for driving to job sites, hauling machinery and parking in construction zones. The same goes for its mechanical twin, the Chevrolet Silverado Work Truck. But if you're looking for a few more amenities, we strongly recommend moving up to a midrange Sierra or Silverado model.
