A light-duty pickup truck with a rugged exterior and the performance to match—not to mention a long list of best-in-class, first-in-class, and segment-first accolades—the 2021 GMC Sierra 1500 is as tough and capable a truck as you’ll find on the market.

A bold front end on the 2021 GMC Sierra 1500 makes a bold entrance, with signature C-shaped LED headlamps adding an aesthetic flourish. Though the reality is, anyone looking at a Sierra is in the market for exceptional utility—and it just so happens that’s what this 2021 GMC pickup offers. That starts with the option of adding the world’s first Six-Function MultiPro Tailgate, in addition to a cargo bed with more cargo volume than any of its competitors. An available carbon-fiber composite bed is another industry-first, while the interior of the Sierra is no slouch either. Heated, premium leather-appointed front seats grace the SLT trim and up, and an available 15” diagonal Head-Up Display and Rear Camera Mirror is—you guessed it—another first-in-class feature. 


An array of engine choices help power the 2021 GMC Sierra 1500 forward with ease, with a heavy-load in tow or not. On one end, a base 4.3L EcoTec3 engine pairs with a 6-speed automatic to produce 285 horsepower and 305 lb-ft of torque, while at the other end, the 6.2L EcoTec3 V8 matched to a 10-speed automatic transmission offers up an astounding 420 horses and 460 lb-ft of torque. With all the gas engines equipped with Active Fuel Management, it’s no wonder they all offer such impressive fuel economy, though it’s hard to go wrong with the 3.0L Duramax® Turbo Diesel engine, also offering up 460 lb-ft of torque. Not that this should come as a surprise, but the 277 horsepower of the Duramax® option provides best-in-class light duty diesel horsepower—as if there were a bit of a theme here.
