Watch GMC's Live Reveal Of The 2019 Sierra Here

The new Chevrolet Silverado's slightly more upscale sibling debuts very soon.

GMC will officially unveil the new 2019 Sierra in a live stream at 3:00 PM EST in Detroit, which is 20:00 GMT or 12:00 PM PST.

As in previous generations, the latest Sierra will share its chassis and many of its other components with the latest Chevrolet Silverado. The new underpinnings make greater use of aluminum and high-strength steels to shed hundreds of pounds over the previous model..

The GMC will differentiate itself with a different front end that will include new, bracket-shaped LED running lights. The two trucks will also have similar cabins, but the Sierra will be available with more premium materials, particularly in Denali spec.

The available powertrains will very likely come from the Silverado, too. Customers will be able to get engines like a 5.3- and 6.2-liter V8. It'll also possibly share the Chevy's new 3.0-liter turbocharged inline-six diesel. A 10-speed automatic gearbox will also be available on some trims.
