Which Sierra 1500 does Edmunds recommend?
Edmunds' Expert Review
Overall rating7.1 / 10
The 2018 GMC Sierra 1500 doesn't get any big changes this year, but it didn't really need any. The Sierra, which shares its design with the Chevy Silverado, is highly capable when it comes to towing and is an all-around impressive and luxurious truck.
Available with three different engines and with multiple body and bed configurations, the 2018 GMC Sierra 1500 is as customizable as any full-size truck on the road today. In the right configuration, it can tow more than 12,000 pounds. Yet the Sierra is also available with a long list of luxury and safety features and is very easy to live with on a daily basis. There are some drawbacks with the Sierra, including the slightly underwhelming base powertrain (a 4.3-liter V6 that we recommend replacing with one of the optional V8s) and the somewhat dated interior. But overall it's a strong offering from GMC in a highly competitive class.
2018 GMC Sierra 1500 configurations
The 2018 GMC Sierra 1500 is available in four trim levels: base, SLE, SLT and Denali. They are available in various cab and bed configurations. The base is relatively sparsely equipped, though a few options are available. We recommend buyers look to the SLE trim level at a minimum because it has features beyond what you'd find in a work-only truck. The version that strikes the best balance between amenities and functionality is the SLT trim level, while the range-topping Denali's luxury will appeal to buyers who want it all.
Configurations are as follows: Regular cabs are offered with a standard bed (6 feet 7 inches) or an extended bed (8 feet); double cabs come only with the standard bed; and crew cabs are available with a standard bed or a short bed (5 feet 9 inches). Be aware that not all trim levels are available with all configurations. All cab configurations are available with four-wheel drive.
The base Sierra comes with a 4.3-liter V6 (285 horsepower, 305 pound-feet of torque), a six-speed automatic transmission, 17-inch steel wheels, automatic xenon headlamps, power locks, a locking tailgate, power windows, air conditioning, cruise control, a rearview camera, a tilt-only steering wheel, Bluetooth, a 7-inch touchscreen interface, USB connectivity and a six-speaker sound system.
The Sierra Convenience package adds remote keyless entry, a remote-locking tailgate, heated power mirrors, a 110-volt AC outlet and LED cargo box lighting. The Elevation Edition includes those items plus special 20-inch black alloy wheels, LED foglights, body-color exterior trim and OnStar communications (with 4G LTE and Wi-Fi hotspot).
The SLE trim level adds 17-inch alloy wheels, a damped tailgate, a leather-wrapped steering wheel and an upgraded 8-inch touchscreen.
Many more options are available on the SLE. The SLE's Convenience package adds rear parking sensors, a rear window defogger, a sliding rear window and power-adjustable pedals. The Preferred package adds remote start, a tilt-and-telescoping steering wheel (V8 only), an power-adjustable driver seat and dual-zone automatic climate control. The SLE Value package adds the same items plus trailering equipment and a rear locking differential. Other options include leather upholstery, a full center console, a power-adjustable front passenger seat and wireless smartphone charging.
Stepping up to the SLT, our trim level of choice, nets you the 5.3-liter V8 (355 hp, 383 lb-ft), an eight-speed automatic transmission, power-folding and heated mirrors, leather upholstery and heated front seats. A 6.2-liter V8 (420 hp, 460 lb-ft) is optional. Other options for the SLT include front and rear parking sensors, a power-sliding rear window, a heated steering wheel, full LED headlights, a spray-in bedliner, navigation, a sunroof and a seven-speaker Bose audio system.
GMC offers an Enhanced Driver Alert package for the SLE and SLT. It includes driver assistance features such as a forward collision warning system with low-speed automatic emergency braking as well as lane departure warning and intervention.
Available on the SLT crew and double cabs are two different off-road-focused packages called the All-Terrain and All-Terrain X. The All-Terrain package adds a few features mentioned above plus some exterior styling changes, an off-road suspension featuring Rancho shocks and an underbody shield. The All-Terrain X package is similar in theme but lacks the off-road suspension.
At the top of the range is the Denali, which comes with most of the features available on lower trim levels and has all of the available driver assistance features. It adds exclusive adaptive suspension dampers, 20-inch wheels and unique interior appointments.
Each vehicle typically comes in multiple versions, although trim levels share many aspects.
The ratings in this review are based on our full test of the 2017 GMC Sierra 1500 Denali Crew Cab Short Bed (6.2L V8 | 8-speed automatic | 4WD | 5-foot-9 bed).
NOTE: Since this test was conducted, the current GMC Sierra 1500 has received some very minor revisions, including the addition of optional upgraded brakes. Our findings remain broadly applicable to this year's GMC Sierra.

GMC Sierra 1500 vs. the competition
2018 GMC Sierra 1500
2018 Ford F-150
GMC Sierra 1500 vs. Ford F-150
The 2018 Ford F-150 is the Sierra's chief competitor in the full-size pickup market. The F-150 is available in more trims with a greater range of engines, making it a more customizable vehicle than the Sierra. Whether you're looking for a budget-friendly workhorse, a luxury cruiser or an off-road adventurer, there's an F-150 in the lineup for you.
GMC Sierra 1500 vs. Toyota Tundra
The Toyota Tundra is the old man in the light-duty class, with roots that stretch back to the 2007 model year. It has some strengths, including a standard V8 and competitive pricing. However, the mandatory V8 means the Tundra isn't as fuel-efficient as rivals with standard V6 engines, and the Tundra's engine is even thirstier than competing V8s. The interior is showing its age, while the ride is noticeably less refined than others in the class.
GMC Sierra 1500 vs. GMC Sierra 2500HD
The GMC Sierra 2500HD is the heavy-duty version of the Sierra 1500 light-duty pickup, so it's more concerned with ultimate towing and hauling capabilities than passenger comfort. Properly configured with the available diesel-powered V8, the Sierra 2500HD can tow considerably more than the 1500. It's more expensive, though, and it's possible a 1500 will still easily meet your needs.
2018 GMC Sierra 1500 Double Cab for Sale
The GMC Sierra is essentially a rebadged version of the Chevrolet Silverado, and though there are certainly differences in trim as well as price, the trucks are identical from a functional standpoint. Both are good pickups, and choosing between them is a matter of personal taste. At its heart, though, the Sierra is the same hard-working truck we've come to know and respect.
The Sierra can be had with three different engines, all designed to deliver strong low-end torque, which is exactly what a pickup truck needs to get those heavy loads moving. The base engine is a 4.3-liter V6 rated at 285 horsepower and 305 pound-feet of torque. An optional 5.3-liter V8 offers 355 hp and 383 lb-ft of torque. For those who want as much muscle as possible, GMC offers a big 6.2-liter V8 that delivers 420 hp and 460 lb-ft of torque. It turns the Sierra into one of the fastest-accelerating full-size pickups you can buy. All engines feature an automatic transmission and rear- or four-wheel drive.
GMC offers a wide selection of bed and cab options. Regular-cab trucks can be had with a standard (6-foot-7-inch) bed or a long (8-foot) bed. Extended cabs come exclusively with the standard bed, and the four-door crew cab can be paired with either a short (5-foot-9-inch) bed or a standard bed. All cabs are nicely finished with broad, soft seats that offer good long-distance comfort, though overall cab space isn't as generous as in some competing trucks. We like the quality of the interior and the easy-to-learn control layout, though we wish the side mirrors were bigger.
The Sierra is a pleasant truck to drive on a daily basis. The steering is reasonably responsive for a pickup truck, and the ride is quiet and smooth, if not quite best in class. Big trucks will always be ponderous on a curvy road, and the Sierra 1500 is no exception, but overall its responses are good. The 4WD models get a low-range transfer case, and when equipped with the Z71 suspension package and more aggressive tires, the Sierra 1500 is a capable off-roader.
GMC offers the Sierra in four trim levels: base, SLE, SLT and Denali. We think most noncommercial buyers will be happy with the SLE or the SLT, which have more of the amenities we like to see for daily driving. For those who want it all, the Denali trim turns the Sierra 1500 into a proper luxury truck. Edmunds can help find the perfect 2018 GMC Sierra 1500 for you.

Should I lease or buy a 2018 GMC Sierra 1500?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
