The Final Word Roadtrip List

The 48 contiguous United States sprawl throughout roughly three.12 million sq. miles of land, or greater than 33 occasions the floor space of all the United Kingdom. Over there, they invented tiny roadsters that slip tidily down slim lanes lined with hedgerows. Right here, effectively, it’s completely different.

Witness the 2017 Chevrolet Silverado 3500HD, a heavy-duty pickup truck that casts an infinite 21.5-foot-long shadow and takes up eight toes of lane width in its largest and widest configuration, which we examined right here. The LT trim provides $5525 to the $43,715 base value of a four-wheel-drive crew-cab, long-bed Work Truck and brings options resembling an Eight.Zero-inch touchscreen infotainment system, a four.2-inch gauge-cluster show, and material seats (instead of vinyl) to the inside. Tack on one other $1150 for the Twin Rear Wheel choice, which ours had.

Dualie Obligation

Whereas each dualie and nondualie Silverado 3500HDs are ready haulers, those that commonly tow heavy masses will wish to spend extra coin for the additional rubber and flared field that provides 15.5 inches to the truck’s width. The extra wheels unfold the load over 4 rear tires. In testing, we have been in a position to deliver the extra-wide 3500HD dualie to a halt from 70 mph in an inexpensive 199 toes, or seven toes shorter than a dualie Ram 3500 Heavy Obligation.

For those who’re actually critical about towing, you’ll wish to improve from the 3500HD’s normal 360-hp gasoline-swilling 6.Zero-liter V-Eight to the 445-hp 6.6-liter Duramax turbo-diesel V-Eight fitted to our check truck. It prices greater than $9000 to make the swap, however with solely its iron block and valvetrain shared with final yr’s Duramax mill, the just about all-new engine sees critical efficiency good points over its predecessor. Horsepower rises by 48, whereas torque will increase to an enormous 910 lb-ft at 1600 rpm—145 lb-ft greater than final yr’s engine and 530 lb-ft greater than the bottom 6.Zero-liter V-Eight. Add $2955 to get the four-by-four model to distribute all that torque extra effectively.

An overwrought however practical hood scoop is restricted to diesel-equipped 2017 Silverado 3500HDs (and their GMC Sierra counterparts) and feeds a brand new air consumption for the massive 403-cubic-inch engine, which Basic Motors says helps the engine run higher and cooler beneath load. Preserving that machine from overheating is not any small activity when this truck is charged with towing as much as 22,700 kilos from its bed-mounted gooseneck hitch receiver ($370). Order the one cab, and that towing capability goes as much as 23,300 kilos of gooseneck- or fifth-wheel-hitched trailer and contents—8700 kilos greater than probably the most succesful gas-burning Silverado 3500HD.

Though robust, the Silverado 3500HD’s towing functionality is way from class main; equally geared up Ford F-350 Tremendous Obligation and Ram 3500 vans are in a position to tow as much as 31,300 and 30,240 kilos of gooseneck-hitched trailer.

Each day Dualie

Regardless of the Silverado lacks in outright towing potential, it greater than makes up for in refinement and civility, as Chevy’s newest turbo-diesel V-Eight engine is as spectacular in day-to-day driving as it’s on paper. Energy builds seamlessly, and the engine’s huge wave of seemingly lag-free torque helps the 8440-pound brute transfer with confidence. Unladen, the weighty Silverado 3500HD punished our check monitor’s pavement, zooming from zero to 60 mph in a surprisingly fast 6.6 seconds and masking the quarter-mile in 15.1 seconds at 91 mph. These figures examine favorably with a 2509-pound Fiat 124 Spider Abarth we examined, which wanted an extra Zero.1 second to hit 60 mph and matched the 3500HD diesel within the quarter-mile. Passing occasions from 30 to 50 mph and 50 to 70 mph are much better than you’d anticipate of a four-ton block of steel.

Equally as spectacular was the truck’s quiet operation, as simply 73 decibels of noise punches into the cabin beneath full acceleration—three decibels fewer than we measured in a Mercedes-Benz E300 4MATIC. At 70 mph, we recorded a hushed 67 decibels, or equal to that of the four-cylinder, mid-size Mercedes sedan. This can be a huge diesel truck, bear in mind.

Diesel-powered Silverado 3500HDs relegate cog-swapping duties to an Allison six-speed computerized transmission that’s each bit as clean because the nine-speed computerized discovered within the aforementioned Mercedes. A manual-shifting mode managed by a rocker swap on the steering-column-mounted gearshift lever permits drivers to carry gears as much as the diesel’s gasoline cutoff (at roughly 3500 rpm) with out worry of an unwarranted upshift. Annoyingly, Chevy doesn’t mark a redline on the truck’s tachometer. Our noticed gasoline financial system rang in at a median of 13 mpg all through the 3500HD’s time with us, though that determine doesn’t embody the 16 mpg that we achieved on our 75-mph freeway loop (nor, as is our coverage, the time we spent with the accelerator matted on the check monitor). The EPA doesn’t fee gasoline financial system for vans with a gross car weight score of greater than 8500 kilos, however a comparable Ram 3500 recorded 16 mpg general throughout its stick with us (it didn’t go on our freeway loop).

Unsurprisingly, retaining greater than 4 tons of truck planted to the bottom is not any straightforward activity, and the 3500HD dualie’s stability-control system intervened after the truck circled our skidpad at simply Zero.68 g. Nonetheless, the 3500HD dualie by no means feels notably unwieldy in day-to-day driving; as a substitute it drives a lot smaller than its measurement would recommend. Credit score the truck’s dull-feeling however comparatively fast and well-weighted power-assisted recirculating-ball steering system. The tiller’s slim on-center useless spot was a revelation in comparison with the colossal on-center lifelessness present in competing Ford and Ram vans. As we’ve famous in earlier assessments of GM pickups, the Silverado 3500HD’s four-spoke steering wheel is offset barely towards the appropriate of the motive force’s seat, which drives a few of our staffers loopy—but others say they don’t discover the offset in any respect.

Including It Up

Additional including to the convenience of piloting the 3500HD dualie have been a number of dealer-installed cameras fitted to our check truck, together with two cameras beneath every of the truck’s huge side-view mirrors ($999) and one other digicam overlooking the mattress ($499). All three digicam feeds displayed their views inside our LT-trimmed 3500HD’s MyLink infotainment system’s Eight.Zero-inch touchscreen. As in different Chevrolet merchandise, MyLink proved straightforward to make use of, with logical menus and fast contact inputs. A handful of onerous buttons on the sprint, in addition to giant knobs for quantity and tuning, made it straightforward to make fast and easy infotainment changes on the fly.

Whereas the LT trim’s normal rearview digicam, Bluetooth telephone and audio streaming, and steering-wheel-mounted audio controls provide sufficient luxuries for many Silverado 3500HD consumers, Chevrolet fitted our crew-cab check truck with a number of different accessible options. These included navigation and Bose audio for a complete of $995, heated material bucket seats bisected by an enormous heart console for $980, and $395 price of side-curtain and front-seat facet airbags. The $1625 LT Comfort bundle introduced energy driver’s-seat changes, dual-zone local weather management, distant begin, a rear-window defroster, a 110-volt family energy outlet, and entrance fog lamps, whereas the $815 LT Plus bundle added a rear parking-assist system, power-adjustable pedals, and an influence sliding rear window. Outdoors, our check truck wore a $55 radiator cowl, a set of 4 movable tie-down factors within the mattress for $60, a $395 coat of Deep Blue Ocean Metallic paint, $495 in spray-on bedliner, and $750 price of chrome facet steps. Out the door, our check mannequin price a complete of $67,828—par for the one-ton-truck course. Nonetheless, we have been stunned that it didn’t embody leather-based seating surfaces or a proximity key with push-button begin, the latter of which is unavailable in any Silverado.

This huge truck concedes towing-capacity bragging rights to its rivals but gives the nonetheless noteworthy potential to tug 11-plus tons, together with refined street manners—it’s quiet inside, it rides effectively, and it steers higher than we’ve come to anticipate of such giant machines. And it actually strikes out when the motive force faucets into the facility.

In America, enormous is the norm, and the Chevrolet Silverado 3500HD crew-cab dualie does an awesome job of constructing huge really feel completely atypical.
