GM's TurboMax Upgrade Gives Colorado And Canyon 350 HP

• GM documentation points to the 2027 Colorado and Canyon using the L4B TurboMax at 350 horsepower and 455 lb-ft.
• Published towing and payload details are still pending, with GM materials indicating maximum towing around 7,700 pounds.
• TurboMax changes include a new turbocharger, revised fuel injection, updated thermal management, and redesigned pistons.

Chevrolet and GMC are giving their midsize trucks the same engine upgrade that just landed on the Silverado and Sierra. Order information and GM documentation for the 2027 Colorado and Canyon point to a new L4B TurboMax rating that moves these trucks into a different power bracket than the model they replace.
