Chevy Silverado HD gets new interior, more diesel power

DETROIT — Chevrolet is updating the heavy-duty line of its Silverado pickups with a standard 10-speed transmission, a more powerful diesel engine, a plusher interior and new trailering technologies.

The 2024 Silverado HD, which debuted Monday and is slated to go on sale in the first half of next year, will offer an off-road ZR2 trim for the first time. It will face off against Ford's redesigned Super Duty pickups, which are scheduled to be revealed Tuesday.

"We've designed the Silverado HD to be our customers' favored choice for true truck capability," Scott Bell, vice president of Chevrolet, said in a statement. "The enhancements to the 2024 model build on its core strengths to provide an even stronger balance of the design, strength and confidence that makes tackling the hard jobs, including trailering, easier and more convenient than ever."

The truck's front end has been freshened with a new fascia, new headlights and new grille. Other exterior changes include standard tow hooks, "CHEVROLET" lettering on the hood scoop and six new paint colors. A new High Country Midnight Edition features black chrome accents, high-gloss black wheels and black badging.

The interior is revamped to feel more open and modern, with a flow-under console designed to create the spaciousness of a bench seat, Chevy said. LT, LTZ and High Country trucks have a new instrument panel design with a 13.4-inch infotainment screen and 12.3-inch configurable driver information screen. A head-up display is available.

"It's an environment that intentionally puts more at the driver's fingertips, for a greater feeling of confidence and connection with the vehicle," said Phil Zak, executive director of global Chevrolet design.

The 6.6-liter V-8 gasoline engine from today's truck is unchanged, but it will come with an Allison 10-speed automatic transmission instead of a six-speed to provide more on-demand towing power and allow greater engine-braking control, Chevy said. The combination enables a 26,000-pound gross combined weight rating, up from 24,000 pounds.

The optional Duramax 6.6-liter turbodiesel V-8 will offer 470 hp, up from 445 now, and 975 pound-feet of torque, up from 910, Chevy said. Engineers increased torque by up to 25 percent at low speeds and when climbing hills.

New trailering technologies include a version of adaptive cruise control that accounts for increased drag and braking distances, an enhanced Transparent Trailer feature that lets drivers see behind fifth-wheel and gooseneck setups, trailer side blind-zone alert, and a gross combined weight alert that measures acceleration and torque to detect if the vehicle and trailer are too heavy.

Pricing and fuel economy ratings will be released closer to the start of production. The truck will be built in Flint, Mich., and Oshawa, Ontario.

Chevy says it has the highest retail market share in the U.S. heavy-duty pickup segment.

HD models accounted for about one-third of U.S. Silverado sales in the first half of this year. Silverado HD sales rose 15 percent from January through June, compared with an 18 percent drop for the 1500.
