2019 Silverado and Sierra 1500 Testing in Colorado!

Different Exhaust Tip Design Shows Different Trim, Possible Diesel

General Motors is full speed ahead on development work on the 2019 fullsize trucks, as evidenced by these shots of the next-generation GMC Sierra and Chevrolet Silverado 1500 testing in Colorado. GM has done a good job of cladding the trucks in such a way that they appear to be Ford F-150s. However, there are a few giveaways that they’re from the General. We’ve already determined the front window cut-down is a fake. A close look at the rear bumper shows the GM’s signature bumper corner steps, a feature that debuted on the 2014 models. The front LED driving lights are also lower on the fascia than on the F-150.

One interesting change noted on this particular group of mules compared to previous spy shots is the exhaust tips. Most of the models we’ve seen up until this point have had rectangular dual rear outlets. These tips are round. We did not get close enough to see if they were Venturi tips or not, which would indicate a diesel engine. Considering how aggressively GM is promoting diesels in its other models—such as the Chevrolet Colorado, Cruze, and Equinox, as well as the GMC Terrain—we feel the likelihood of a V-6 diesel in the next-gen Silverado and Sierra 1500 is practically a given. We’re betting on a 3.0-3.5L V-6 with at least 250 hp and more than 400 lb-ft of torque. We expect the main transmission to be the new 10-speed automatic codeveloped with Ford. Lower-trim models may retain the eight-speed 8L90E automatic.
