Top 10 Reasons to Buy a 2018 GMC Sierra 3500 – The Pros

1. Base Engine Packs Performance

While some drivers will ultimately choose the optional diesel engine, the standard V8 engine also packs a big punch. It is rated to pump out a healthy 360 horsepower and 380 pound-feet of torque. You will always have plenty of muscle under the hood. When equipped with the base engine, the 2018 Sierra 3500 can tow up to 13,000 pounds.

2. Very Potent Diesel Engine

If you need the optimum pulling power, look no further than the optional Duramax diesel engine. It now pumps out 445 horsepower and a crushing 910 pound-feet of torque. When behind the wheel of the diesel-powered Sierra 3500, it feels as if you are driving a freight train. A fifth-wheel tow hitch enables you to confidently pull up to 23,300 pounds.

3. All Terrain X Package

The All Terrain X package is for the drivers who plan to take their adventure off-road. It comes with all of the necessary goodies to help you overcome nature’s challenges. Protective skid plates and a Z71 off-road suspension give you an extra peace of mind when facing rough terrain. Meanwhile, the truck’s Eaton automatic locking rear differential helps give you the maximum traction.

4. Smooth, Quiet Ride

Whether you are heading down to your local home improvement store or taking a long road trip, the 2018 GMC Sierra 3500 will deliver a smooth ride. The suspension system is tuned just right. GMC also did a superb job of insulating the Sierra 3500’s cabin. Even when speeding down the interstate, this pickup still remains quiet.

5. Exceptional Handling for a Full-Size Truck

The 2018 GMC Sierra 3500 manages to somewhat hide its massive weight. It corners like a much smaller pickup truck. Upon taking a sharp curve, most drivers are pleasantly surprised by the Sierra 3500’s lack of body roll. Because the steering system is so precise, drivers can easily maneuver this full-size truck on the road.

6. Beautiful Appearance

Some people consider the 2018 GMC Sierra 3500 to be the best-looking pickup in the class. You certainly can’t miss its bold front fascia. The truck’s powerful grille and piercing headlights give it a commanding road presence. If you really want to impress your family and friends, choose the Denali model. Chrome exterior trim and a stunning set of wheels make it look spectacular.

7. Great for Families

Your family will certainly appreciate the Sierra 3500’s roomy cabin. The crew cab version provides ample space for everyone. You can take a cross-country journey without hearing any complaints about legroom. You will also find the truck’s seats to be incredibly comfortable and supportive. Ventilated front seats come standard in the ultra-plush Denali model.

8. Driver Alert Package

To obtain a greater sense of security on the road, opt for the Driver Alert package. It includes a number of advanced driving aids. If a potential road hazard is detected, the pickup’s Safety Alert Seat will immediately vibrate to get your attention. This package also includes forward collision warning, parking sensors, and lane departure warning.

9. Extremely Luxurious Denali Model

For the drivers who demand nothing but the best, GMC offers the featured-packed Denali model. It comes loaded with all the bells and whistles. While you are enjoying your day, you can listen to your favorite songs via the booming Bose sound system. Meanwhile, a wireless charger enables you to keep your smartphone fully energized.

10. Top-Rated OnStar Communications System

All trims can be equipped with an award-winning OnStar system. Not only can you use this advanced communications to quickly contact emergency personnel, but you can also use it to obtain turn-by-turn driving directions.

Reasons Not to Buy a 2018 GMC Sierra 3500 – The Cons

1. Lower than Average Fuel Consumption

Don’t expect the 2018 GMC Sierra 3500 to deliver the best fuel economy. Although the EPA does not officially list a fuel economy rating for the Sierra 3500, it will deliver worse gas mileage than the light-duty Sierra 1500. If you truly don’t need to tow an extremely massive load, stick with the Sierra 1500.

2. No Manual Gearbox

Drivers who love to shift their own gears will be out of luck with the 2018 GMC Sierra 3500. While the truck’s heavy-duty automatic transmission performs well, it can't match the sense of control provided by a traditional manual transmission. The 2018 Ram 3500 is currently the only pickup in the segment that offers a stick-shift gearbox.

3. Can Be a Pain to Park

The new Sierra 3500 is obviously a large vehicle. When you are trying to park in a busy downtown area, you will need to take full advantage of the truck’s backup camera. Maneuvering with a trailer on the back can be an even more difficult task.

How it Stacks up to the Competition:

Some of the other key players in this segment include the 2018 Ram 3500 and the 2018 Ford F-350 Super Duty. In regard to handling, the 2018 GMC Sierra 3500 is hard to beat. It is also the only truck in the class that offers a vibrating Safety Alert Seat.


When shopping for a heavy-duty pickup truck, be sure to take the 2018 GMC Sierra 3500 for a spin. Despite this truck’s large size, it is a pure pleasure to drive. While all versions of the Sierra 3500 provide lots of interior room, the Denali model provides top-notch luxury.
