Larger dimensions, more technology, more capability, and more expressive designs. #GMC has always delivered most of those features and for 2020, their flagship #SierraHD gets the same full makeover as its smaller half-ton 1500 sibling. Its 6.6L #Duramax #Diesel V8 carries over, mated to a new 10-speed Allison transmission, while max towing capacity swells to well over 30,000 pounds.
