General Motors has debuted it’s 2020 Chevrolet Silverado HD, which the company calls the strongest, most capable ever, with a 52% increase in towing capacity over its predecessor.
“We set out to make the best HD trucks on the market, bar none,” said Jaclyn McQuaid, chief engineer, Silverado HD. “We increased towing capabilities across the line, not just for dually buyers. We added class-leading towing technologies, such as 15 available camera views, to make trailering more convenient, whether pulling a large cargo trailer or fifth-wheel camper. And we made a host of changes to make tasks easier.”
Dimensionally, the new truck is longer, wider and taller, riding on a 132-mm longer wheelbase, and shares only the roof with its light-duty Silverado cousins. It will be available in up to 22 cab, bed, chassis and drivetrain configurations, and come in five trim levels — Work Truck, Custom, LT, LTZ and High Country.
Two new powertrains will be available — base fitment is a 401-hp 6.6-litre V-8 mated to a 6-speed automatic (with increases of 11% in horsepower and 22% increase in torque, up to 464 lb-ft, resulting in 18% better towing capacity), while the 6.6-litre Duramax turbodiesel V-8, linked to the Allison 10-speed automatic, makes 445 hp and 910 lb-ft of torque, allowing it to tow up to 16,103 kg (a 52% improvement), in regular cab, rear wheel drive.
Other noteworthy features include advanced trailering technologies, including a “transparent trailer” virtually created through the use of 15 available camera views (with an optional accessory camera), BedStep cargobox sidesteps and rear-bumper corner steps, and an Autotrac active 2-speed transfer case on 4x4 models, allowing seamless transfer in torque between the 2WD and 4WD in a “4 Auto” mode.
Among noteworthy technologies is an onboard trailering app that can perform light tests, diagnostics, and monitor tire pressure and temperatures. It also offers a pre-departure checklist and maintenance reminders.
Other technologies include Auto Park Brake Assist (to aid in hitching up a trailer), Park Grade Hold Assist, integrated trailer-brake control and digital variable steering assist. Others include a tow/haul mode, hill start assist, hill descent control, trailer sway control, and rollover avoidance.
