2024 Sierra 2500HD


What's new for 2024

Here at SOUTH TEXAS BUICK-GMC, it is our mission to be the automotive home of drivers in the McAllen, TX area. We provide a vast selection of new and used vehicles, exceptional car care and customer service with a smile!

And it is with great pleasure that we introduce the all new 2024 GMC 2500HD.  With a new look and increased towing capacity, the new 2500HD will be the top full-sized pick-up on the market. V-8 Gas or Diesel configurations will get you down the road and ready to work.

Comfort at work & play

At SOUTH TEXAS BUICK-GMC we think that you will simply not get out of the new 2500HD once you take it for a ride.  With new trim packages available and a standard eight inch touchscreen, up to a massive 13.4 inch on some trims levels.  The Denali Ultimate model features leather wrapped components and wood inlays.  While these luxurious features will make you fall in love, it's the practicality of the 2500HD's layout that will make it a relationship that will last.  With a split bench or bucket seats up front, there's a configuration for you. Along with extensive passenger space in the crew cab, the GMC is full of interior cubby storage. Its standard and long cargo boxes have built-in steps on both sides of the bed and the rear bumper has them at each corner. The box can be further customized with LED lighting, movable tie-downs, and a 120-volt outlet.  

All the power you need & more

We touched on the power before, but it bears repeating.  The new Sierra 2500HD is powerful and smooth.  With the gas V-8 you are getting an amazing 401HP and 464 pound feet of torque.  While the Duramax Diesel ups the game with 470HP and 975 pound feet of torque.  Both engines run with a 10 speed automatic transmission, assuring that you won't miss a beat towing down the highway.  You'll come away from your test ride (and all your rides) remarking how refined and responsive the 2024 Sierra HD is.
