Fuel Economy

Now, let's be realistic, fuel economy isn't usually the top priority for heavy-duty truck buyers. However, it's still a factor to consider. The Sierra HD Denali Ultimate's fuel economy will vary depending on the engine you choose and how you drive it. The gasoline engine will generally offer better fuel economy than the diesel engine, but the diesel engine will provide significantly more torque for towing.

The Sierra HD Denali Ultimate is equipped with a number of features that can help to improve fuel economy, such as automatic stop/start and aerodynamic enhancements. These features can help you to save fuel, especially during city driving. While the Sierra HD Denali Ultimate may not be the most fuel-efficient vehicle on the road, it's important to remember that it's a heavy-duty truck designed for serious work. If fuel economy is a major concern, you may want to consider a lighter-duty truck or SUV.

Pricing and Trims

The Sierra HD Denali Ultimate sits at the top of the Sierra HD lineup, so it comes with a premium price tag. The exact price will vary depending on the options and packages you choose. It's always a good idea to check with your local GMC dealer for the most up-to-date pricing information. While the Sierra HD Denali Ultimate is the most luxurious trim level, the Sierra HD is available in a variety of other trims to suit different needs and budgets. The base trim level offers a more affordable option for those who don't need all the bells and whistles. The SLE and SLT trims offer a good balance of features and value. And the standard Denali trim provides a step up in luxury and refinement. No matter which trim level you choose, you can be sure that you're getting a capable and reliable heavy-duty truck.
