Unlike other websites and magazines, our ratings are not based solely on a singular road test, but rather a more encompassing batch of criteria: quality, safety, comfort, performance, fuel economy, reliability history and value. When comparing vehicles using our Rating System, it's important to note that the rating earned by each vehicle correlates only to the models within its class. For example, a compact car cannot be compared to a SUV—They are different vehicles altogether.
You can interpret our ratings in the following way:
5-Star: Outstanding vehicle. Only the most exceptional vehicles achieve this rating.
4-Star: Very Good vehicle. Very good and close to being the best vehicle in its class.
3-Star: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.
2-Star: Below average vehicle. Not recommended, and lacking attributes a car buyer would come to expect for the price.
1-Star: Poor vehicle. Simply does not deserve to be on the road.
2017 GMC Sierra 1500 OVERVIEW
The GMC Sierra 1500 plays to a diverse crowd who all agree on one thing: there's no substitute for a full-size pickup truck. Buyers within that group usually think Ford or Chevy, but those who want an extra measure of style or just something different have naturally gravitated toward the GMC.
What's New for 2017
All models receive a capless fuel fill system and a Teen Driver feature allows parents to monitor driving habits. Some option packages have been condensed and renamed. Automatic emergency braking is available for this first time.
Choosing Your GMC Sierra 1500
Like its Chevy twin, the Sierra is available with three cab styles: Regular, Double, and Crew. The Double Cab features a rear seat and narrow rear doors, while the Crew Cab is a bona fide four-door with adult-size legroom in back. Regular and Double Cabs come with a 6.5-foot bed; an 8-foot bed is optional on the Regular Cab only. As for the Crew Cab, the standard box is slightly shorter than the others at 5.75 feet, but the 6.5-foot bed is available as an upgrade.
The engine roster starts with a 285-horsepower 4.3-liter V6. Beyond that, there are two V8s: a 5.3-liter with 335 horsepower and a 6.2-liter that makes a stout 420 horsepower.
Towing capacity maxes out at 7,600 pounds with the V6, 11,500 with the 5.3-liter, and an even 12,000 pounds with the 6.2-liter.
A six-speed automatic transmission comes standard with the V6 and 5.3-liter engines. An eight-speed unit is optional for the 5.3-liter and standard with the 6.2-liter. Four-wheel drive is available across the board.
Like all full-size pickups, the 1500 covers an enormous swath of market territory across its five trim levels:
For buyers into off-roading, the SLE and SLT can get an All-Terrain package with hill-descent control, skid plates, special shock absorbers, a heavy-duty air cleaner, recovery hooks, and various appearance elements.
The SLE is our pick for combined work and personal use. It can be skewed toward either end depending on your needs and without threatening your budget.
