Did the 2026 Chevrolet Trailblazer receive any powertrain updates compared to the 2025 model year?
For the 2026 model year, General Motors retained both Trailblazer engines — the 1.2L turbocharged three-cylinder (137 hp) and the 1.3L turbocharged four-cylinder (155 hp) — but revised the CVT calibration to improve throttle response out of corners. The RS AWD variant also benefits from a more defined Sport mode with sharper virtual shift points. No systemic mechanical issues have been reported on this model year to date, suggesting a mature and refined powertrain lineup entering its fourth year on the current platform.
