The 2019 GMC Sierra got a bit of polishing in the level of sophistication of its interior. More noteworthy, though, is the MultiPro tailgate. You can not find this option on any other trucks out there as of now. It has six different options for folding down, creating steps, interior fold-down to make cargo more accessible, and so on. Another addition is an industry-first carbon fiber tailgate bed. This makes for a lighter and stronger cargo bed. New under the hood this year is a 2.7-liter turbocharged inline four-cylinder. This option adds performance and fuel economy to the Sierra. Otherwise, the Sierra retains the same 4.3-liter V6 engine with the choices of a 5.3 or 6.2-liter V8 as an upgrade. Both the GMC Savana 2500 and Savana 3500 gained forward-collision warning and lane-departure warning features. It also a theft-alert notification as an option this year.
