Engine and Drivetrain Choices

The heart of any GMC Sierra for Long Hauls. The right powertrain can mean the difference between a frustrating, expensive journey and a smooth, efficient one. The GMC Sierra offers a range of engine options, each with a different personality, but one, in particular, stands out for the long road.

The Gas Guzzlers: V8 Power

The GMC Sierra offers two powerful V8 gasoline engine options. The GMC Sierra for Long Hauls is a workhorse, producing 355 horsepower and 383 lb-ft of torque. It’s a proven and reliable engine that gets the job done. The more potent 6.2L V8, with its 420 horsepower and 460 lb-ft of torque, provides an exhilarating burst of acceleration and impressive towing capability. Both engines are paired with a smooth-shifting 10-speed automatic transmission, which helps them stay in the power band and optimize fuel economy.

However, for a true long-haul driver, the GMC Sierra for Long Hauls have a notable drawback: fuel consumption. While their highway fuel economy is respectable (19-21 MPG on the highway), it can quickly become a significant expense on a long trip, especially when towing. Their primary benefit is raw power, which, while fun, may not be the most economical choice for a driver whose primary concern is miles per dollar.

The GMC Sierra for Long Hauls: The 3.0L Duramax Turbo-Diesel

If there is a single reason to choose the GMC Sierra for Long Hauls-distance driving, it is this engine. The 3.0L Duramax Turbo-Diesel is an absolute game-changer.

This immense torque is available at low RPMs, making it incredibly responsive for merging onto the highway or passing other vehicles without a struggle.

But the real magic of the Duramax is its fuel efficiency. With a two-wheel-drive configuration, it achieves an impressive 29 GMC Sierra for Long Hauls on the highway and 23 MPG in the city. Even with four-wheel drive, those numbers only drop slightly to 27 MPG on the highway. Over a long trip of thousands of miles, the fuel savings become substantial. The Duramax also has a quiet and refined nature, a far cry from the loud, rattling diesels of the past. Its smooth performance and superior efficiency make it the top choice for any long-haul driver who wants a truck that feels effortless on the open road.

The City Slicker: The Turbo Four-Cylinder

The base turbocharged 2.7L four-cylinder engine is a surprisingly capable and torquey option. With 310 horsepower and 430 lb-ft of torque, it offers great performance for a truck this size. However, it’s not the ideal engine for a long-haul driver. It’s designed to be a budget-friendly option for those who primarily use their truck for daily city commutes. Its highway fuel economy is lower than the diesel’s, and the engine feels less relaxed at highway speeds, which can GMC Sierra for Long Hauls to driver fatigue over a long journey.

• Final Word on Engines: For the long-haul driver, the 3.0L Duramax Turbo-Diesel is the undisputed champion. It offers the perfect blend of high torque for towing and class-leading fuel economy that will save you money and reduce the frequency of your fuel stops.

The Command Center: Cabin Comfort and Technology

When you’re spending hours or even days on the road, the truck’s cabin becomes your office, your dining room, and your sanctuary. The GMC Sierra has made significant strides in its interior, particularly in higher trim levels, to make it a truly comfortable place for the long haul.

The Ultimate Comfort Test

A GMC Sierra for Long Hauls can be physically demanding, and a comfortable seat is non-negotiable. The Sierra’s front seats, especially in the SLT, AT4, and Denali trims, are among the best in the segment. They offer excellent support, a wide range of power adjustments, and, on some models, lumbar support. The Denali Ultimate trim takes it to a new level with 16-way power-adjustable front seats and a massage function—a feature that can be a lifesaver on an all-day drive.

Noise reduction is another key factor for reducing fatigue. The GMC Sierra for Long Hauls cabin is exceptionally quiet at highway speeds, thanks to a well-insulated design and features like active noise cancellation. This allows for clear conversation, music, or a peaceful ride, which is invaluable for a long trip.

Infotainment and Connectivity

The GMC Sierra’s infotainment system is a major upgrade. The centerpiece of the updated interior is a large, vibrant 13.4-inch diagonal touchscreen. It’s responsive and features Google built-in compatibility, which means you have access to Google Maps for navigation and Google Assistant for hands-free commands. This is a game-changer for long-haul drivers who need reliable navigation and want to minimize distractions. The system also includes wireless Apple CarPlay and Android Auto, a built-in Wi-Fi hotspot, and multiple USB ports to keep all your devices charged and connected.

The available 12.3-inch digital Driver Information Center is fully customizable, allowing you to display critical information like fuel range, trip data, and even trailer vitals directly in your line of sight. This reduces the need to look away from the road to check on your vehicle’s status.

Driver-Assistance Features

Technology that reduces driver fatigue and enhances safety is paramount. The GMC Sierra offers a comprehensive suite of driver-assistance features, including:

• Adaptive Cruise Control: This system automatically adjusts your speed to maintain a safe distance from the vehicle in front of you, reducing the constant need for throttle and brake input.

• Super Cruise: On the top-tier Denali Ultimate, this hands-free driving technology allows the driver to take their hands off the wheel on compatible highways, making a long, boring drive significantly less taxing. This feature is a major selling point for anyone who logs serious highway miles.

The Workhorse: Towing and Hauling

A long-haul truck must be capable of more than just a comfortable ride. It must be able to tow and haul with confidence. The GMC Sierra offers a suite of advanced features that make it a segment leader in this regard.

Towing Confidence

With the 3.0L Duramax diesel engine, the GMC Sierra for Long Hauls 1500 boasts a best-in-class maximum towing capacity of up to 13,300 lbs. But it’s not just about the numbers; it’s about the technology that makes towing easier and safer.

The available ProGrade Trailering System is a masterpiece of engineering. It’s a comprehensive suite of tools that includes:

• An in-vehicle trailering app: This allows you to create custom trailer GMC Sierra for Long Hauls, run pre-departure checklists, and track important data.
• Trailer tire pressure and temperature monitoring: This gives you a real-time view of your trailer’s vitals, helping you avoid a dangerous blowout on the highway.
• Hitch Guidance with Hitch View: This uses the rearview camera to provide a close-up view of the hitch, making it easy to line up and connect a trailer on your own.

These features make hooking up a trailer a one-person job and reduce the GMC Sierra for Long Hauls, which is crucial for a long-haul journey.

The MultiPro Tailgate

GMC’s innovative MultiPro Tailgate is more than a gimmick. Its six unique functions are surprisingly useful for a long-haul driver. It can convert into a full-width step for easy bed access, a work surface for setting up a laptop or tools, or a load stop to secure long items. This versatility makes it a perfect companion for drivers who need to use their GMC Sierra for Long Hauls for both work and personal use on the same trip.

The Bottom Line: Reliability and Cost of Ownership

No matter how comfortable or capable a truck is, it’s not a good choice for the long haul if it spends its life in the shop. The GMC Sierra for Long Hauls has a well-earned reputation for being a durable and dependable truck.

Long-Term Reliability

The GMC Sierra benefits from decades of shared engineering with the Chevrolet Silverado. Both are known for their GMC Sierra for Long Hauls longevity, with many owners reporting well over 200,000 miles on their vehicles. The 3.0L Duramax diesel, in particular, has a design that is built to handle the rigors of high mileage with its inline-six configuration, which is inherently balanced and smooth. While maintenance costs for diesel engines can be slightly higher than for their gasoline counterparts, the reduction in fuel costs and the peace of mind of having a truck designed for the long run make it a worthwhile investment.

Fuel Costs and Maintenance

When considering the cost of ownership, it’s not just the purchase price that matters. The average annual maintenance cost for a GMC Sierra for Long Hauls 1500 is in line with other full-size trucks, but the true savings for a long-hauler come from the fuel pump. Over a period of 50,000 miles, the fuel savings from the Duramax diesel over a comparable gas V8 can be in the thousands of dollars, easily offsetting the higher initial cost and any potential for more complex maintenance.
