CR Model Summary
The HD Sierra and its twin the Chevrolet Silverado HD are designed for heavy towing and hauling. The 6.0-liter V8 and 6.6-liter turbodiesel, both mated to a six-speed automatic, carried over on the 2015 redesign. There is also a natural gas (CNG) version of the 6.0-liter V8. GM said that the new cabs and interiors provide increased space and comfort, with extensive storage space. The Sierra 3500HD is available with head-curtain and seat-mounted side airbags. Braking and handling capabilities on the outgoing HD Sierra come close to those of the Sierra 1500. Handling is not agile but has a modicum of responsiveness that other three-quarter-ton trucks don't provide, but it rides more stiffly than the Sierra 1500.
