8 cylinders, 8.3 liters — Chevrolet Silverado HD 2027 gets HD power
Chevrolet has updated the 2027 Silverado HD: the pickup has received a new 8.3-liter turbocharged diesel V8, rack-and-pinion steering, and electric brake assist.
For the 2027 model year, Chevrolet has retained the previous design of the Silverado HD but updated the engines, steering, and brakes. The vehicle was tested in Tucson, Arizona, on public roads and off-road terrain.
The main change is the new 8.3-liter turbocharged diesel V8 engine. It delivers 555 hp and 1,667.7 Nm of torque. The maximum towing capacity for a conventional trailer is 9 tonnes, and for a gooseneck trailer, it is 17,250 kg. The gasoline V8, after modifications, produces 412 hp and 639.95 Nm of torque.
Instead of the traditional recirculating-ball steering system, the Silverado HD now features a rack-and-pinion system. During the test drive, it demonstrated more precise and quicker response compared to the steering of other heavy-duty pickups. The electric assist eliminates pumps and hoses, which, according to the test authors, may reduce noise and maintenance needs.
The brakes have been upgraded with an electric booster and larger front mechanisms. The diameter of the brake discs is 14.6 inches, and the calipers have four pistons. On winding mountain roads, the pickup proved to be precise and controllable, although the stiff suspension tuning is designed for cargo transport and towing.
The vehicle's exterior remains unchanged: the massive radiator grille and integrated side steps are still in place. The Trail Boss package is now available for the Custom trim, and the ZR2 can be enhanced with the American Expedition Vehicles Bison package. The base WT and Custom trims retain the old instrument cluster and a 7-inch infotainment screen. Higher trims feature a 12.3-inch digital instrument display and a 13.4-inch infotainment screen. The test authors described the seats in all versions as flat and firm.
