2023 Chevrolet Silverado 1500: What's New, Specs & Features
Last updated August 4, 2026
The main change for the 2023 Chevrolet Silverado 1500 is a stronger second-generation 3.0-liter Duramax turbo-diesel on select trims. Otherwise, this is a light update that largely carries over the 2022 truck’s styling, cabin tech, safety features, and trim lineup.
About the 2023 Chevrolet Silverado 1500
4th generation Silverado 1500 (2019-present), fifth model year and second year after the major 2022 refresh.
The Silverado 1500 is Chevrolet’s broad-appeal full-size pickup: one model range that stretches from basic work truck to sporty street truck, lifted off-road trims, and a near-luxury flagship. Chevrolet positions it around towing confidence, bed usefulness, a wide spread of trims, and strong tech on LT and above. What sets it apart is the sheer variety within one lineup, especially the Trail Boss and ZR2 off-road branches plus the diesel option on many upper trims.
The 2023 lineup stretches from the straightforward Work Truck to the more comfortable LT, the luxury-leaning High Country, and the off-road-focused Trail Boss and ZR2 models. LT and higher-end trims stand out for their 13.4-inch touchscreen and 12.3-inch digital gauge display, while ZR2 adds specialized off-road suspension, locking differentials at both axles, and underbody skid plates.

2023 Chevrolet Silverado 1500
(443 reviews)
“The acceleration is amazing, seats are comfortable and feel like they hug you, yet have the right amount of lumbar support. I get compliments on the truck often. My favorite part is the whistle of the turbo when you're passing someone or climbing a steep hill/mountain.”
“The Chevy Silverado is amazing, very comfortable, fits me great, and that's why I keep buying them.”
