Chevrolet Silverado

Chevrolet’s latest Silverado 1500 enters the 2019 model year with butch new styling, fresh engine tech, and a diesel engine option. Unlike the aluminum-bodied Ford F-150, the Silverado sticks with mostly steel construction—yet it loses up to 450 pounds thanks to some clever engineering. As the full-size-pickup market heats up with an all-new Ram 1500, a refreshed F-150, and Nissan’s recently updated Titan, the Silverado’s advancements are critical.


Chevrolet’s weapon in the ever-raging truck wars is the rugged, adaptable, and trusty Silverado 1500. Clever storage cubbies are spread throughout the cabin, and stout towing capacities mean hauling extra stuff is a snap. Not sold on the Chevy’s styling? Check out its more handsome twin, the GMC Sierra 1500.


Based on the new Chevrolet Silverado 2019 , and inspired by the success of the Velociraptor 6×6, which in turn is a modified Ford Raptor, Hennessey launches the Goliath 6×6, an all-terrain vehicle of huge dimensions and impressive power. On the well-known and very capable off-road platform of the GM group, Z71; and the Trail Boss version of Chevrolet’s latest pickup, Hennessey took to the extreme his interpretation of a conqueror of dunes, mud, rivers, breccias and, in short, whatever is put in front of him car cover for miata convertible.

Engines, Ride, and Handling

A range of engines—including a V-6, two V-8s, a turbocharged four-cylinder, and a diesel inline-six—means there’s a 2019 Silverado 1500 for any job. Of the two V-8s, the 420-hp 6.2-liter is our choice; in our testing, it motivated the Silverado to 60 mph in 5.4 seconds while the smaller 355-hp 5.3-liter needed 6.1 seconds. The 310-hp turbocharged 2.7-liter four-cylinder still offers decent towing capacity, but needed 7.0 seconds to hit 60 mph and delivered worse fuel economy than the 5.3-liter V-8 in our 200-mile highway fuel-economy test. On the road, the big truck drives smaller than it is; handling is surprisingly agile, and the suspension delivers a smooth ride. The 2020 Chevy Silverado shuffles its powertrain offerings, making the largest V-8 and 10-speed automatic more widely available.

Interior and Technology

From the stripped-down Work Truck model to the downright luxurious High Country, the Silverado can be equipped in a multitude of ways. Base models offer nothing but the essentials, including manually adjustable front seats, manual locks and windows, and vinyl seats, but a 7.0-inch infotainment touchscreen with Apple CarPlay capability also comes standard. Moving up the range unlocks all sorts of goodies, including a larger 8.0-inch infotainment display, in-dash navigation, a head-up display, ventilated front seats, and wireless smartphone charging. A host of driver-assistance features are offered but none are standard; automated emergency braking with pedestrian detection, lane-keeping assist, and automatic high-beam headlamps are all available assistance features. Chevrolet unveiled the Silverado High Country HD 2015, which will hit the US market by the end of the first half of this year, giving a premium touch to the country’s heavy truck segment. Presented today at the Denver Motor Show, the new pickup has received a chrome front grille with horizontal bars, along with the body-colored front and rear bumpers, as well as unique 20-inch chrome alloy wheels.

Model Features

Inside the cabin the model features upholstered in brown color and the eight-inch touchscreen of the Chevrolet MyLink system. It also features a Bose sound system, perforated seats that can be heated or cooled, and a front and rear parking assistant.

Entertainment System

Should they wish to shell out more, customers can set up Silverado High Country HD 2015 with a rear seat entertainment system (with DVD and Blu-ray player), navigation system and sunroof along with a High Country Premium package with adjustable pedals, heated steering wheel and warning items for the driver.

Engine and Power

Like other Silverado HDs, this new version can be equipped with a 360 hp 6.0 V8 engine.An all-new 6.6-liter gasoline V-8 bumps base-engine output to 401 horsepower and 464 lb-ft of torque over last year’s 6.0-liter Silverado HD gas engine, which generated 360 horsepower and 380 lb-ft of torque. The gas engine is coupled exclusively to a six-speed automatic transmission, and each powertrain offers only a single axle ratio (3.73 gas, 3.42 diesel). Gas-engine-equipped Silverados max out at a 17,400-pound towing capacity.


52.4 mkgf of torque, which can also be purchased in a bi-fuel version running on compressed natural gas. The Chevrolet is also offering a larger 6.6-liter Duramax V8 turbodiesel of 397 hp and 105.6 mkgf of torque through a six-speed automatic transmission.

Chevrolet Silverado HD

That the 2020 Chevrolet Silverado HD diesel’s new cooling fan looks like a windmill blade assembly is not a coincidence. It’s huge. And by huge, we mean 28 inches in diameter. If appearances tell the truth, the thing could cool a nuclear reactor. Or the Earth’s core. Or even the sun itself. Yet it’s but one component in a variety of chassis and powertrain changes that allow Chevy’s diesel-powered Silverado 2500 and 3500 pickups to reset the max-towing bar among HD trucks.


A new Allison 10-speed transmission is paired with the diesel engine, as are beefed-up prop shafts and a larger 12-inch rear axle on 3500s. At 35,500 pounds, the 2020 Silverado HD’s maximum trailering weight is a massive 52 percent higher than the 2019 Silverado HD. But that’s a mere 400 pounds clear of the bar set only months ago by the Ram 3500, and it’s only 500 pounds more than the 2019 Ford Super Duty, which is also being replaced for 2020. Those are academic numbers, of course, especially considering that the peak number is always achieved with a single-cab, dual-rear-wheel, two-wheel-drive truck. You know, the one no one buys. What’s more, although its tow ratings are increased, the Silverado HD’s optional 6.6-liter diesel maintains the same output as last year—445 horsepower and 910 lb-ft of torque.

Real-World Towing

We towed two trailers around the central Oregon mountains in the new Silverados: a 12,000-pound open-deck utility trailer using the gas-engine Silverado and a 14,000-pound enclosed trailer with the diesel. Both trucks were single-rear-wheel, crew-cab, all-wheel-drive models. The gas-drinking truck, a mildly optioned Custom trim priced at $47,520, certainly felt the weight on a road that rose and fell between 4000 and 6000 feet. Still, patience is necessary when moving anything this heavy, and the load was within the powertrain’s capability. The six-speed transmission delivered perfectly rev-matched downshifts when slowing and on grades to help control speed. The narrow two-lane roads, however, where there’s a premium on steering precision and feedback, showed the limits of the chassis. And limits aren’t really something we enjoy exploring while piloting nine tons of steel and rubber.

Factors involved in Chevrolet Silverado

Two factors were at play: Lower-trim trucks (Work Truck, Custom, and LT) use hydraulic-assist steering where higher trims (LTZ and High Country) get electric-assist steering—Enhanced Digital Variable Assist Steering in the Chevy vernacular. The electric-assist setup allows engineers to tune the steering specifically for use in Tow/Haul mode, permitting additional damping and effort, which dramatically improves confidence during heavy trailering. Also, the lighter trailer hitched to the gas-powered truck wasn’t equipped with a weight-distributing hitch, which shifts more weight to the front axle to normalize steering. Combined, these differences were significant in detracting from the towing experience.

2020 Chevrolet Silverado HD Efficiency

The diesel truck, however, is a mountain-moving sweetheart. You get what you pay for with the $9750 diesel option and the better-equipped High Country. Even towing several thousand pounds more than the gas truck, it was clear that if you’re towing frequently and the loads are heavy, there’s no substitute for the diesel. With nearly double the torque of the gas engine and four more gears from which to choose, the Duramax was secure in its ability to pick a speed and haul uphill. Even with the equivalent of four Corvette Stingrays in tow, the 2500 was able to maintain 60 mph up the steepest slopes available. More important was its ability to maintain downhill speed using the exhaust brake, which operates silently and is engaged using a switch on the dash. Simply achieve the speed you want to hold, activate the exhaust brake, and steer.

Bigger, Better

All Silverado HD trucks are updated with new bodywork this year and share only their roof sheetmetal with the 1500. They’re bigger, too. Crew-cab models get 5.2 inches more wheelbase, 10.4 inches more length, and 1.4 inches more width than last year’s trucks. The result is three inches more rear legroom. An HD-specific bed is also longer and holds higher volume (nine more cubes on standard bed and seven more cubes on the long bed) than on 2019 models.


Chevrolet is serious about diesel-engine longevity to the extent that it’s added an after-run feature to Duramax-equipped pickups for 2020. The feature alerts the driver when the transmission is put in Park if the engine needs additional cooling time and will restart itself to enable cooling for up to 15 minutes should the driver opt to kill the engine.

Allison Transmission

The new Allison transmission also is available with an optional power takeoff for driving dump bodies or salt spreaders, and the air dam and skid plate are now easily removable for less intrusive snowplow installation. And haven’t you always wanted a less intrusive snowplow, really?

2020 Chevrolet Silverado HD Camera

Chevy’s convincingly effective, yet nameless, new camera system is available across the HD lineup. The system offers 15 different views from eight cameras, including (optionally) one on the back of the trailer and one inside. Chevy claims 12 percent of pickup drivers have engaged in a fight with a spouse, friend, or family member while towing. (It’s an unsubstantiated claim but a claim nonetheless.) Fortunately, the system, which leaves virtually no blind spots, will effectively eliminate your need for friends or spouses, thereby eliminating two of life’s biggest struggles. Additionally, the system unquestionably makes towing easier and safer by bringing into view the previously unseen, which would be a handy feature for the rest of life as well.

Capability and Safety

What we’re trying to say here is that the new Chevy HD pickups have moved the genre forward another notch with more capability and safety, all while reducing or eliminating some of towing’s more burdensome hassles. That some of their trucks could benefit from better steering likely won’t bother the big-tonnage crew that buys these rigs. They’ll be more than satisfied with the ability to yank around houses in their daily driver. And they will be impressed with that big fan, no doubt.
