Picture of 2021 GMC Sierra 1500

Unless you can’t live without the deeply-satisfying rumble of a V8 engine, the 2021 GMC Sierra 1500 is at its best when equipped with the affordable Duramax turbodiesel inline-six.

GMC is the “professional grade” brand at General Motors, but that’s just marketing mumbo jumbo. The 2021 GMC Sierra 1500 is the same thing as a Chevrolet Silverado 1500, but with different styling and a handful of unique features, like an optional carbon-fiber composite cargo bed. This year, GMC makes several changes to its full-size light-duty pickup truck, none of them earth-shattering. This remains a fundamentally appealing truck in need of attention to the details.

I love everything about this truck, so much I bought one. I got one with the 3liter duramax. Hopefully it’ll be the last truck I’ll ever own.
