What's New for 2018?
Currently in its third generation, the 2018 GMC Sierra 1500 4wd gets just a few tweaks this year in preparation for the all-new version expected in 2019. While Crimson Red Metallic and Pepperdust Metallic are no longer offered as exterior colors, they've been replaced by Red Quartz Tintcoat and Deep Mahogany Metallic.

Top 10 Reasons to Buy a 2018 GMC Sierra 1500 4WD – The Pros
1. High-Quality, Well-Appointed Cabin
While most full-size pickup drivers aren't seeking luxury, that doesn't mean they won't appreciate the hushed ride and superior materials in this truck's interior. In fact, some reviewers compare the cabin of the Sierra's higher trims to those of luxury sedans. The large, supportive seats offer comfort for passengers of all sizes.
2. Powerful Engine Options
2018 GMC Sierra 1500 4wd drivers can stick with the standard V6 or opt for one of two upgraded V8s. Even the base engine, which provides 285 horsepower and 305 pound-feet of torque, is capable of towing. It's also a fuel-efficient choice in the full-size truck class, earning an EPA-estimated 18/24 city/highway miles per gallon. If you prefer a V8, you have the choice of either 5.8-liter boasting 355 horsepower and 383 pound-feet of torque or the 420 horsepower and 460 pound-feet of torque of a 6.2-liter V8. Though the V8s will be more expensive at the pump, their ratings (16/22 city/highway) beat those of competing trucks with comparable engines.
3. Flexible Cab Configurations
The ability to add more passenger seating makes the 2018 GMC Sierra 1500 4wd

Not only is the cab configuration adjustable, you can also select the ideal bed length for your 2018 GMC Sierra 1500 4wd. Choose from the 5'8" short box, 6'6" standard box, or massize 8' long box.

The truck's maximum payload is 2,250 pounds.

Reasons Not to Buy a 2018 GMC Sierra 1500 4WD – The Cons
1. Less-Than-Smooth Ride
Although the 2018 GMC Sierra 1500 4wd is equipped to handle rough terrain, it's a bumpy ride with the standard suspension. Reviewers also note that the Sierra is not easily maneuverable, even for a full-size truck. However, you can choose the Denali trim for adjustable suspension that adapts to the terrain, which mitigates this issue a bit.
2. Challenging LATCH Connectors
While the Sierra can ostensibly accommodate three child safety seats in its two larger cab models, reviewers note that it is very difficult to access the LATCH connectors and secure the seats safely.
3. Limited Legroom
Those who opt for the mid-level cab may find that larger passengers have difficulty sitting comfortably in the second row.
How it Stacks Up to the Competition
The 2018 GMC Sierra 1500 4wd is one of the best full-size pickups on the road. Its closest competitor is the Chevrolet Silverado 1500, a very similar truck that's slightly less expensive. However, it doesn't have the refined interior of the GMC. The Ford F-150 has slightly higher safety ratings and more power, but also falls short when it comes to comfort, style, and features.
Overall, the 2018 Sierra deserves its high rankings from industry sources and consumers. Consider the vehicle named a Motor Trend Truck of the Year finalist.
