The 2020 GMC Sierra 1500 is a full-size pickup truck available in regular-cab, crew-cab, and double-cab configurations. The 2020 model presents new trim levels and a newly designed engine. In addition to the previous engine options, the Sierra 1500 offers the upgraded Duramax turbocharged diesel inline-six option that has been planned for at least a year. It first appeared on the 2019 Sierra options sheet but was removed due to a delay in the certification process. This engine is different than other V6’s because it is a straight-six which also consumes more engine compartment room. However, these types of engines operate more smoothly and generate more torque. The Sierra HD (heavy duty) offers more powerful and extensive specs under the hood.
