2019 GMC Sierra 1500 Diesel Spied and Detailed

, , Leave a comment

GMC is frequently testing its new generation half-ton pickup truck and we are constantly getting new spy shots. The latest set of photos is showing a prototype of the 2019 GMC Sierra 1500 Diesel. We know because our photographers managed to catch the truck underneath. What we don’t know for sure is what’s cooking under the hood of the oil-burner.

Oil-Chugging Options Mated to A 10-speed Transmission

Judging by the information we have, GMC will offer two diesel options with the new generation Sierra 1500. The base model will use either a Navistar 3.0-liter inline-six or a 2.8-liter four-cylinder which currently powers the smaller Colorado. We are betting on the four-cylinder unit because it already turned to be good option beneath the hood of the smaller sibling.

As for the more potent option, the truck is going to use a 4.5-liter V8 Duramax. The option is capable of delivering 310 horsepower and 520 lb-ft of torque, which is more than enough for this kind of pickup. We don’t know whether the manufacturer has a plan to coupe some of these units with a new 10-speed auto transmission or not, but we know it’s going to be available with gasoline units. Either way, the current eight-speed automatic gearbox will stay standard across the range without any doubt.

On Styling and Materials

The underneath photos show diesel truck and filters, so it’s the 2019 GMC Sierra 1500 Diesel without any doubt. What we can see here are styling changes. The pickup sports plenty of them, but the camouflage prevents our effort to see what’s happening beneath. Still, we know what’s cooking under the skin. If you scratch the surface, you might not find steel but some other materials. Not so long ago GM criticized other carmakers because of overall usage of aluminum, and now they are heading in the same direction. Though, they won’t make their 2019 GMC Sierra 1500 Diesel completely from that lightweight material. Instead, the pickup will probably retain steel bed, while the new cab should be totally aluminum.

Official Debut in Early 2018

The redesigned 2019 Sierra 1500 will be introduced at the 2018 Detroit auto show. We should catch a few testing models until then, so stay tuned for updates.
