We caught a pickup truck prototype underneath. The vehicle features a diesel-fuel tank and exhaust system, plus a specific filter for oil-chugging mills only. Normally, this is not too exciting if this is a Ram 1500 diesel, but it’s not. No, this is the all-new 2019 GMC Sierra 1500 Diesel – a half-ton truck that’s going to receive a total redesign and diesel treatment. Of course, Sierra’s sibling from Chevrolet will undergo the same changes.
As for the 2019 Sierra 1500 Diesel, it definitely features an oil-burner under the hood, but we don’t know which one. According to the latest reports, the truck might even get two options of the kind. The most potent model might use a 4.5-liter V8 Duramax capable of delivering up to 310 horsepower and 520 lb-ft of torque.
The base version of the pickup will rely on either Colorado’s 2.8-liter four-cylinder or Navistar 3.0-liter inline-six. If it is the four-cylinder mill, it will likely come updated and improved by turbocharger and injectors.
The redesigned 2019 GMC Sierra 1500 won’t rely on diesel power only. No, the truck will also host a number of series changes, including a new platform and suspension. The new architecture will definitely involve more lightweight materials. However, we don’t believe the truck will get all-aluminum treatment. Instead, the carmaker would probably make ally cabin, while the bed should retain steel. That’s our opinion, because GM had lots of critics for Ford’s all-aluminum F-150, especially on the bed made from the material.
The 2019 GMC Sierra 1500 Diesel won’t be the only option available of course. No, the carmaker will likely keep some of the existing gasoline options and add at least two new. Some sources indicate the pickup is getting a new turbocharged four-cylinder as a base option, while other say it’s going to be a six-cylinder. Anyway, it’s pretty clear that they are working on the new option.
Plus, the redesigned pickup might get a mild hybrid system and definitely a start/stop system. GMC’s half-ton truck will probably keep an eight-speed automatic transmission, but there will be an optional 10-speed auto gearbox.
The carmaker hasn’t set the official date of arrival for the 2019 GMC Sierra 1500 Diesel. However, we think it’s going to be introduced either at 2018 Detroit auto show, or a little bit later in Chicago.
