Miles Overview
The 2020 Sierra 1500 is GMC's full-size pickup, slotting above the Chevrolet Silverado with a more upscale cabin and exclusive Denali trim. The Sierra rides with a composed, planted feel, and its steering is accurate for a truck this size, making highway miles easy. Inside, the cabin is spacious and quiet, with available leather and wood trim that give the Denali a genuinely premium atmosphere. The bed offers handy features like a multi-position tailgate and an available carbon-fiber bed, and the crew cab fits adults comfortably. The SLT adds leather seating, heated front seats, and a larger touchscreen over the Elevation, giving it a more premium feel without the Denali's price tag. Under the hood is a 3.0L I6 diesel making 355 horsepower and 383 lb-ft of torque, paired with a ten-speed automatic and four-wheel drive that delivers strong low-end grunt for towing and gets 19 mpg combined. The SLT can be had with the available MultiPro tailgate, which gives you six different positions for easier bed access and loading.
