GMC Sierra What’s New for 2018

Sierra 1500

The GMC Sierra is now in the 5th model of the third generation and only subtle changes have been made for the 2018 model year. The trim lineup is as follows; Sierra, Elevation Edition (Sierra), SLE, Elevation Edition (SLE), SLT, All Terrain, Denali.

Two new colors are added and two old colors are deleted. Crimson red and Pepperdust metallic are no longer. They are replaced with Deep Mahogany Metallic and Red Quartz Tintcoat. There are no photos available yet from GMC press on those colors in the 1500 Sierra, however, a similar mahogany color was used back in 2016. It looks to be a brownish color with a hint of purple. Then new red color looks to be a lot brighter than the Crimson red.

The 2018 GMC Sierra will now feature a tire pressure ‘Tire Fill Alert’ system which gives an audio and visual alert outside the truck when inflating the tire, so you know when it’s at the correct pressure. The base model will now get a 7″ color touchscreen radio and all trucks will back up cameras. 4 speaker systems will now be upgraded to a 6 speaker system. Brembo performance brake kit now available as an option.
