What Makes the 2021 Sierra HD Stand Out From the Rest?


The latest GMC Sierra High Definition comes with two almost similar engine types that differ in torque value. Drivers can settle on a 6.6-litre direct-injection V8 engine with 464 pound-feet of torque and 401 horsepower. Conversely, drivers can pay for more torque in the 6.6-litre turbo diesel engine that delivers a substantial 445 horsepower and a torque value of 910 pound-feet.

The basic configuration of the 2021 GMC Sierra Heavy Duty trucks is the rear-wheel-drive (RWD). However, drivers have the liberty to select a four-wheel-drive as an alternative to the RWD. Trims such as the Denali and AT4 come with the 4WD as the standard.

The gasoline V8 engine works with a six-speed automatic transmission while the turbodiesel links with a ten-speed automatic transmission. It boasts an integrated engine exhaust brake that can become activated at the push of a button. Thus, when the 2021 GMC Sierra is moving downhill, the system adjusts the truck's speed. Moreover, the exhaust brake can collaborate with adaptive cruise control to dictate what pace is a driver should maintain while moving in hilly terrain.
