2019 GMC Sierra: Less Silverado This Time Around by Evan Williams February 1, 2018 Share Comments The GMC Sierra will arrive March 1st, and this time it’ll be more different from the Silverado than ever. Or at least that’s the expectation, according to Automotive News. They’re reporting that the Sierra will be less Silverado than the current, nearly-identical trucks. The powertrains and underpinnings are likely to be the same though, expect a 3.0-liter diesel inline six with a 10-speed automatic, plus 5.3 and 6.2-liter V8s with dynamic fuel management. The new Sierra will be set apart by the body and the interior, that means more styling changes than the usual different grille and same everything else. Hopefully, it also means that the Sierra will get interiors that are more special to GMC. And not just in the top-spec Denali trim. It will share the new Silverado’s design that makes the truck longer and bigger, the new design also helps it shed 450 lbs lighter thanks to the use of more high-strength steel. Expect the good stuff like the Silverado’s power-open tailgate to be shared as well. We’ll get our first full look at the 2019 GMC Sierra come this time next month.
