General Motor’s Heavy Duty Trucks: Like Driving a Luxury Car that Tackles Heavy Duty Jobs
Size doesn’t matter; it’s the way you manage the numbers is what matters. Well, that is the case with the manner with which General Motors puts the numbers to road with their 2015 Heavy Duty pickup trucks. The engineers who accompanied me on my test drive of the new 2015 Chevy Silverado HD and GMC Sierra HD trucks were quite open with the fact that on paper their trucks have lower numbers compared to the competition. The real import aspect of the numbers comes when the rubber meets the road, and they are quite happy to show their trucks win that comparison where it matters most.
Twenty percent of the pickup trucks sold in the USA are heavy duty trucks and two thirds of those are diesel powered. In our unscientific testing the new GM trucks came out in front of the competition. From acceleration to controlling downhill speeds while in cruise control, the Chevy and GMC prevailed.
By the numbers the Chevy Silverado HD and the GMC Sierra HD engine choices match. Choices are the 6.0-liter V-8 gasoline engine which produces 360 horsepower and 380 lb ft. or torque. Go with the Duramax diesel power and you get a 6.6-liter V-8 with 397 horsepower and a whopping 765 lb-ft. of torque. Couple the Duramax diesel to the Allison 1000 automatic transmission and you have a powertrain that not only works hard it is a pleasure to do so. The Allison transmission features go beyond being one of the toughest gear boxes in the industry, in the GM HD trucks it offers driver shift controls such as tap up/tap down shifting and Tow/Haul mode that reduces gear changes for smoother transition between shifts and improves the cooling of components when towing or hauling capacity loads.
One of the key points brought out by the engineers was that they designed and engineered these trucks to be efficient and comfortable to those drivers who tend to spend a lot of time behind the wheel as heavy duty truck owners do. In the category of cruise control, drivers want to set it and forget it as they hit the highway. So, that was one of our tests while traveling the interstate, set the cruise to the speed limit and not worry about that long steep down grade. This is one of the areas truck owners see an issue. With GM heavy duties with diesel power it is no longer a concern. The combination of engine exhaust braking and the tow haul mode of the Alison transmission keeps the truck set at the set speed within a couple of miles an hour, plus or minus. The competition, I am afraid to report, continued to pick up speed well over the legal limit on the descent.
Most of us who may have not towed a large RV or horse trailer might wonder how in the heck can a pickup pull one of those behemoths. Granted it takes a bit of practice and nerve to do it, fortunately these GM heavy duty trucks make it seem easier than you might believe. I have towed vehicles such as these on more occasions than I care to count. The one thing that raises its ugly head is the constant attention it takes just to maintain consistent speeds on long hauls. That wasn’t an issue here even with a 19,000 lb fifth-wheel trailer. Maintaining consistent highway speeds was easy with no need for constant adjustment from me in the driver’s seat.
Driving a pickup today isn’t like it was even a few short years ago. Both the Chevrolet HD and GMC HD cabins are full of creature comforts that were once found only on luxury cars. The interiors are well designed and the layouts make viewing the gauges easy and manipulating the switches matter of fact. Visibility from the driver’s seat is better than ever with plenty of glass surrounds. With the large outside rearview mirrors and the advent of rear cameras you have a full view of what is on behind you.
Features such as heated and ventilated, even air conditioned seats are available. Hill start and Hill decent take the apprehension out of taking off from a dead stop or descending a steep hill while hauling a heavy load in the bed or tagging along behind. Having the brakes hold just those few scant seconds with Hill Start takes the anxiety out of climbing hills and finding you have to stop and start off again.
Comfort and great features are part of the General Motors heavy duty truck picture, but those reasons are not the main criteria for truck buyers particularly in the heavy duty market. No surprise that towing and payload capabilities are the top considerations on a truck buyers mind. “Heavy-duty pickups are tools that people use to tow heavy trailers and haul big loads,” said Jeff Luke, executive chief engineer. “Great tools like the new HD pickups don’t just get the job done; they make the work easier, and help you feel more confident tackling the really tough jobs.”
Putting the specification numbers on the road the HD trucks make it so you leave nothing behind. The heavy duty chassis and suspension systems offer up maximum payload capacity of 7,374 pounds and maximum towing capabilities of an astounding 19,600 pounds. Translate that over to fifth-wheel towing and that works out to 23,200 pounds of towing muscle.
Major innovations in the consumer truck category have made driving a truck for work or recreation a pleasant and even enjoyable experience. Work in the heavy duty General Motors trucks seems less of a job and less exhausting and recreation is more fun when the ride is comfortable and pleasant.
Driving and living with the Chevrolet Silverado HD and the GMC Sierra HD for a few days was more fun than work and any time you can interject fun in your work makes for a good day on the job. And, the GM HD trucks make an even better day of being on the road for fun.
