2025 GMC Sierra 2500

The 2025 GMC Sierra 2500 makes an unforgettable first impression, and its diverse range of trim levels ensures there is a perfect configuration for every driver in the Dickinson area. We see the exterior of a truck as its armor, and GMC has forged each Sierra 2500 with a commanding presence and intelligent design. From the work-ready Pro trim, with its durable construction and bold stance, to the progressively more refined SLE and SLT models that add striking chrome accents and distinctive wheel designs, the attention to detail is palpable. For those who venture off the beaten path, the AT4 and AT4X trims offer rugged, off-road-ready aesthetics with specialized suspension and aggressive all-terrain tires. Crowning the lineup, the Denali and the exclusive Denali Ultimate trims present the pinnacle of truck luxury, featuring signature grilles, premium lighting, and exclusive wheel options that command respect on any road. Each model boasts the innovative six-function MultiPro Tailgate, a revolutionary feature that we've found our customers appreciate for its incredible versatility in loading, unloading, and accessing the cargo bed.

At the heart of every 2025 GMC Sierra 2500 lies a powertrain built for immense strength and unwavering reliability. We offer two formidable engine options to ensure you have the right amount of power for your specific needs. The standard 6.6L V8 gas engine is a robust workhorse, delivering 401 horsepower and 464 lb-ft of torque with impressive responsiveness. For the ultimate in trailering and hauling, we recommend the legendary 6.6L Duramax Turbo-Diesel V8 engine. This powerhouse generates an astounding 470 horsepower and a massive 975 lb-ft of torque, providing the confidence to move serious weight without breaking a sweat. Both of these exceptional engines are paired with a sophisticated Allison® 10-speed automatic transmission, a combination that provides smooth, efficient power delivery across the entire power band, ensuring you're always in the right gear for the task at hand.

Performance in the 2025 Sierra 2500 is about more than just raw numbers; it's about delivering a confident and controlled driving experience, no matter the load. When properly equipped, especially with the Duramax Turbo-Diesel, this truck boasts a maximum conventional towing capacity of up to 20,000 pounds and can handle up to 22,390 pounds with a fifth-wheel/gooseneck hitch. Here at Gay Buick GMC, we help our customers configure their trucks with features like the ProGrade Trailering System, which transforms the towing experience. This available system provides a suite of intelligent technologies, including up to 13 available camera views, such as the industry-first transparent trailer view that helps you virtually see through your trailer. The truck’s high-strength steel frame and advanced suspension systems work in concert to manage heavy loads with stability and poise, making long hauls through Texas feel effortless and secure.

Step inside the 2025 GMC Sierra 2500, and you'll discover a cabin crafted to serve as your mobile command center and personal sanctuary. We are particularly proud of the best-in-class Crew Cab front head and legroom, which provides a spacious and comfortable environment for you and your crew. The interior is a masterful blend of functionality and premium comfort. Depending on the trim, you can envelop yourself in durable cloth, sophisticated leather-appointed seats, or even full-grain leather in the Denali Ultimate. Available features like 10-way power-adjustable heated and ventilated front seats ensure comfort on the longest journeys. Dominating the dashboard is the available 13.4-inch diagonal center touchscreen, an intuitive hub for the GMC Premium Infotainment System with Google built-in, offering seamless access to navigation, media, and vehicle settings. Paired with the 12.3-inch diagonal color Driver Information Center, all critical information is presented with brilliant clarity.

Your safety is the highest priority, which is why we are so impressed with the comprehensive suite of safety and driver-assistance features integrated into the 2025 GMC Sierra 2500. Every model is equipped with the Sierra HD Pro Safety package, a bundle of active safety technologies designed to enhance your awareness and help you avoid potential hazards. This standard suite includes Forward Collision Alert, Lane Departure Warning, and Automatic Emergency Braking. For even greater peace of mind on the roads around Dickinson, advanced available features such as HD Surround Vision provide a high-definition, 360-degree view around the truck, simplifying parking and low-speed maneuvering. Adaptive Cruise Control is also available to make highway driving less stressful by maintaining a set gap time from the vehicle you're following. At Gay Buick GMC, we are committed to helping you drive with the utmost confidence, knowing that your Sierra 2500 is engineered to protect.
