What We Like About The 2025 GMC Sierra HD

Picking The Right Engine For The Job

Choosing your engine is going to be the hardest thing that you do when it comes to this truck. The 6.6L V8 Gas Engine provides reliable performance, and it pairs with an Allison 10-speed Automatic Transmission so that you have great handling. If you plan on towing though, then the available Duramax 6.6L Turbo-Diesel V8 Engine is going to be your best bet, as it can get up to 975 lb-ft. of torque. If you’re near St. Louis, Alton, or Edwardsville, and you want to see these engines in person, then you can find the new 2025 Sierra HD at Quality Buick GMC.

The Sierra HD’s Advanced Systems

While you’ll find plenty of cool tech features on this model, you’ll also find work-ready systems like the available:

• Camera Views: With up to 14 available camera views, it’s never been easier to hitch up your trailer. While you’d normally need a spotter, these camera views can make up the difference.
• Adaptive Cruise Control with Trailering: Once you make it on the highway, you’ll be able to let your Sierra HD take over. This way, you can relax while the truck handles your speed and braking.

A Look at Your Displays

This truck offers a staggering amount of tech for your cabin, like the available:

• The 13.4-inch Diagonal Center Touchscreen: Your touchscreen is your main hub, as this is where you’re going to access other features like your apps and music.
• The 15-inch Diagonal Multicolor Head-Up Display: This is the most impressive display out of the three listed here, as it can be found on your windshield.
• The 12.3-inch Diagonal Color Driver Information Center: Keeping track of all of your information has never been easier thanks to this huge screen.

If you need a real workhorse, then you can’t go wrong with the 2025 Sierra HD. You can find it on our lot at Quality Buick GMC.
