2019 GMC Sierra 1500 Diesel Confirmed

As we already wrote, the GMC Sierra 1500 truck had no big changes for a couple of years. After two quiet seasons, the pickup is ready to come back in style and with the show. The company prepared 2019 GMC Sierra 1500 Diesel, and this story is not a rumor anymore. We have this vehicle confirmed, and it is only a matter of time when it will come out.

This will be the response from General Motors to an upcoming F-150 Diesel truck. With this vehicle, Ford would establish itself as a supreme leader in the segment. But, Sierra’s response is at the right time and will give buyers extra option. Nevertheless, styling will also get a refresh, as well as the interior. With all upcoming changes, the GMC Sierra 1500 Diesel will be a legit rival to Ford F-150. We can’t say it is favorite against the most popular truck in the world, but the rival company will definitely have to spy what is going on in GMC.

2019 GMC Sierra 1500 Diesel Spy Shots

The 2019 GMC Sierra 1500 Diesel is already on streets. Well, not as a production model, since its premiere will happen probably in Detroit, at the car show in 2019. We could see test mules, and experts are pretty sure that diesel version is what is caught by spy photos.

Nevertheless, since the Sierra 1500 is heading into a new generation, the vehicle will suffer big styling changes. Heavy camo is proving that and hiding details at the same time. Part of the redesign and new generation is a diesel unit, which will improve towing and off-road capabilities for the truck.

The GM already has a diesel mill in its lineup. It is a 2.8-l Duramax 4-cylinder powertrain, used by Chevy Colorado and GMC Canyon. However, this unit not potent enough for a big truck. With turbo- and superchargers maybe, but we think the company will turn to some other engine.

Duramax alternative

The return of the 6.6-l Duramax is a possibility. With it, Sierra 1500 Diesel will be capable to deliver 300-350 horsepower, with torque level above 550 lb-ft. In the most powerful version, this engine can produce 650 pound-feet of twisting power.


Cummins company is specialized for diesel powertrains. Cooperation between these two is possible, and Cummins has two diesel units that could suit Sierra 1500. The latest edition of 6.7-l turbo-diesel engine dates from 2016. This drivetrain can develop 385 hp and stunning 900 lb-ft of torque. This could be a solution for high-end models, while entry-level truck could get a smaller unit.

Cummins has a response to this request. A 5.0-l V-8 is a perfect match for 2019 GMC Sierra 1500 Diesel. Power output is 310 hp, and it can produce 500 lb-ft of torque. Its rival Ford F-150 plans a turbocharged V-6 unit, and also the same 5.0-l drivetrain.

2019 GMC Sierra 1500 Diesel Redesign

The entire lineup of upcoming Sierra 1500 trucks will get a redesign. Refresh is not going to change overall dimensions of the pickup. Also, the addition of the 2019 GMC Sierra 1500 Diesel is the biggest news. It can also affect the overall weight of the vehicle.

However, the GM is about to use more aluminum and other parts for engine room and body parts. That will save some weight. Also, revisit will make a bed spacious and covered with bed liner.


Inside the cabin, we will find all the latest systems. Recent trucks received a praise for their conventional and reliable equipment. Front seats are comfortable. Leather and heating are standard on all trim levels. Same is with the steering wheel, which has more control buttons for 2019 Sierra 1500. The new truck will add extra USB ports. Also, there is enough room at the center console to store files and tech equipment. The cabin is quiet with help form triple door seals. Also, the design of the valve exhaust system reduces noises from the engine to the minimum level.

2019 GMC Sierra 1500 Diesel Trim Levels

The 2019 GMC Sierra 1500 Diesel will be available in the entry-level model for sure. Standard Sierra includes a rear-view camera and LED daytime running lights. However, we believe that Diesel truck will have extra options with higher trim levels. There are SLE and SLT to offer more equipment. The fans of Sierra All Terrain model will definitely want to see it in diesel variant. Finally, Denali truck is top of the class. Its price says enough about its features list and extra options. Seeing it as a diesel will be interesting.

With 2019 GMC Sierra 1500 Diesel being the most important addition to the lineup, its success is a top priority. The company can achieve it by offering the truck in many different look and trims.
