The GMC Sierra 3500HD CC of 2020 belongs to the third-generation series. With its powerful engine options starting with the standard 6.6L V8 that produces 401 horsepower and 464lb-ft of torque to its upgraded 6.6L Duramax Turbo-Diesel V8 that delivers a jaw-dropping 445 horsepower and 910lb-ft of torque, this vehicle is a formidable presence on the road. Both engines are paired with a 6-speed automatic transmission, and the truck comes in a 4WD drivetrain essentially designed for hard work and heavy towing. Available in five trims - SLT, AT4, Denali, SLE, and base Sierra. The infotainment system includes a 7-inch touchscreen (upgradable to 8 inches), Bluetooth, Apple CarPlay, and Android Auto. Standard safety features include a Rear Vision Camera, Tire Pressure Monitoring System, and StabiliTrak stability control system with Proactive Roll Avoidance – a testament to GMC's dedication to safety.
