Does the 2026 Colorado receive new engines or meaningful powertrain improvements?
The 2026 Colorado carries forward its two powertrains: the 2.7T four-cylinder of 237 hp in base configurations and the 2.7T "Plus" of 310 hp on ZR2, Z71, and Trail Boss trims. New for 2026: revised turbocharger mapping reducing low-rpm response lag — noticeable during loaded towing on grades. The 8-speed automatic also received updated programming for more intuitive behaviour under load. Maximum towing capacity remains at 7,700 lb (3,493 kg) with the appropriate package. No diesel or hybrid variant has been announced for the 2026 Colorado in Canada — GM's electrification focus for truck platforms is concentrated on the Silverado EV and Canyon platforms further out.
