2020 GMC Sierra 2500HD Base Specs

GMC Sierra 2500HD

The entry-level Sierra 2500HD has been designed for durability, not luxury. Tough vinyl covers the seats and there’s manual operation of the windows and door locks. On the Regular Cab, a simple two-speaker sound system is fitted, but thankfully all models have a seven-inch touchscreen infotainment system with Apple CarPlay and Android Auto. Six airbags and a rearview camera are standard, but fortunately, GMC will allow you to fit this model with many more convenience and safety features via a host of optional packages.
