GMC Sierra HD Review

The GMC Sierra HD is meant for the big boy jobs of heavy towing and hauling and it’s a worthy competitor for the Ford and Chevy versions of the same type of truck. It’s loaded with a big beautiful engine, particularly if you go with the Denali version that could seemingly tow anything (that will cost you roughly $15,000 more than the standard edition though). You’ll get nearly 400 horsepower no matter what engine you go with and we like that.
The six speed transmission standard with the GMC Sierra HD makes for beautiful driving. The whole experience is smooth and pleasant in fact and if it’s been a while since you bought a new truck of this class you’ll be delighted at how that’s changed over the years. No more herky jerky shifting and terrible noises; instead it’s just easy and lovely.
