The shots even show its diesel emissions tech.
The GMC Sierra and Chevrolet Silverado pickups have a new generation on the way for the 2019 model year, and a new batch of spy shots reveal the upgraded Sierra under development with a new, diesel engine.
These photos show underneath the truck, which reveals the tank for the exhaust after-treatment fluid and the diesel particulate filter. Unfortunately, the exact powerplant remains a mystery. The most likely possibilities for the engine are either a 3.0-liter inline six that would come from Navistar or a significantly updated version of the 2.8-liter four-cylinder that’s currently available in the Chevy Colorado and GMC Canyon.
Other powertrain changes for General Motors’ pair of trucks reportedly include the addition of a turbocharged V6 into the lineup. The 10-speed automatic from the Camaro ZL1 should be available with some engines, too.
The next-gen Sierra and Silverado will follow the industry’s trend towards making vehicles lighter. They’ll make use of significantly more aluminum, but they’ll allegedly retain a steel bed, which won’t clash with the firm’s anti-Ford marketing. The models will also feature better aerodynamics.
Aesthetically, GM will make mostly evolutionary changes to the trucks’ design. The camouflage hides a lot, but the major tweaks for the Sierra will apparently include a new grille with a mix of horizontal and vertical slats.
GM will build the new Silverado and Sierra in Michigan, rather than Mexico. The move will be part of a $1 billion manufacturing investment that will create or retain 1,500 jobs in the United States.
The next-gen Sierra and Silverado will be 2019 model year vehicles. Look for a debut in late 2018.
