2023 GMC Canyon

The 2023 GMC Canyon represents a significant redesign for the mid-size pickup, boasting a more rugged and refined appeal. It’s generally praised for its improved off-road capability, updated interior, and more powerful standard engine. However, like any new model year, it’s not without its reported issues. The 2023 Canyon comes standard with a turbocharged 2.7L inline-4 engine, offered in three output variants: 237 hp and 260 lb-ft of torque (base Elevation trim, later discontinued), 310 hp and 390 lb-ft of torque (most trims), and 310 hp and 430 lb-ft of torque (High Output). All trims come paired with an 8-speed automatic transmission. Common dislikes include the higher price point compared to previous generations and some perceived cost-cutting measures in certain interior materials.
