Coming off its best June since 2006 and with 12 consecutive months of year-over-year sales gains, GMC is introducing its best-selling truck refreshed for 2016.

Design refinements stick to the exterior and include:

• LED “C-shaped” signature daytime running lights
• LED headlights
• new front fascia and grilles for each trim level
• new LED fog lamps; new bumpers
• new “C-shaped” LED taillights.

The new Sierra will be available in the fourth quarter of this year with more information set to be released closer to then.
