“The 3.0L Duramax Turbo-Diesel engine has long been a favourite of Sierra light-duty owners,” Will Mellon, marketing manager, GMC Sierra, said in a press release. “Since the launch of the refined Duramax for the 2023 model year, around 20 percent of all Sierra 1500s sold have come with the engine, and we expect its addition to the AT4X trim to take mix even higher.”
