The 2019 GMC Sierra 3500HD CC is a heavy-duty full-size pickup that comes in two distinct trims: the base trim and a more upscale SLT trim. With a standard 6.0-liter V8 engine offering 360 horsepower, drivers enjoy remarkable strength. There's also an optional turbo-diesel 6.6-liter V8 for even more power, spurring 445 horsepower and an impressive 910 pound-feet of torque. Both engines are linked to a six-speed automatic transmission, and customers can choose between rear-wheel and four-wheel drive. The vehicle also stands out for its gooseneck/fifth-wheel towing package providing massive towing capabilities. Inside, drivers find a touchscreen with GMC's IntelliLink infotainment system, equipped with Apple CarPlay and Android Auto compatibility. Given its hefty status, safety features are critical; these GMC's trucks incorporate stability control with trailer sway control, and an available Driver Alert package, including forward-collision alert, lane-departure warning, and parking sensors.
