There has been some shuffling around of features for the 2021 GMC Acadia, along with a few alterations to the color palette and the available packages. The Pro Safety Package, which comprises blind-spot monitoring, rear cross-traffic alert, collision avoidance, front and rear parking sensors, and lane management assist, now comes standard on the SLT, all-wheel-drive SLE, AT4, and Denali. The SLE and SLT get access to the new Elevation Edition, which adds 20-inch wheels and all-season tires, along with blacked-out exterior accents. The Premium Package for the SLT and AT4 has been updated, and the same trims get access to the Technology Package. A pretty significant change for this year is that every model aside from the base SL now seats six with standard second-row captain’s chairs. A more minor change is the deletion and addition of several exterior color choices. Finally, Apple CarPlay and Android Auto now offer wireless convenience.
