GM Enhances Colorado and Canyon with New TurboMax Engine, Boosting Horsepower to 350




General Motors is significantly upgrading its 2027 Chevrolet Colorado and GMC Canyon mid-size pickup trucks, equipping them with the potent L4B TurboMax engine. This marks a substantial increase in power, bringing these models to an impressive 350 horsepower and 455 lb-ft of torque. While the exact towing and payload specifications are still awaited, this move positions the Colorado and Canyon with performance figures comparable to their full-size counterparts, showcasing GM's commitment to enhancing its truck lineup's capabilities.
The 2027 Chevrolet Colorado and GMC Canyon are set to feature General Motors' enhanced 2.7-liter turbocharged four-cylinder engine, designated as the L4B variant. Official GM documentation and order guides confirm the robust power and torque figures for these upcoming truck models, indicating a significant performance boost. Specifically, the Enhanced TurboMax engine generates 350 horsepower and 455 lb-ft of torque, peaking at 5,200 rpm for horsepower and 3,000 rpm for torque, as reported by various automotive outlets.
This powertrain update means that the mid-size Colorado and Canyon will achieve power outputs equivalent to GM's larger trucks, such as the Chevrolet Silverado 1500 and GMC Sierra 1500. Such parity between mid-size and full-size truck lines from the same manufacturer is an uncommon strategy, highlighting GM's uniform approach to hardware improvements across its truck portfolio. This consistency extends to other segments, including heavy-duty truck powertrain revisions announced earlier in the year.
Early reports, based on GM's technical documents, suggest that the maximum towing capacity for appropriately equipped Colorado and Canyon models will remain around 7,700 pounds, consistent with the previous generation. However, General Motors has yet to release comprehensive public details regarding the towing and payload ratings for all 2027 configurations. The upgraded L4B TurboMax engine succeeds the L3B TurboMax, which delivered 310 horsepower and 430 lb-ft of torque. The new L4B boasts an increase of 40 horsepower and 25 lb-ft of torque, a notable improvement for a four-cylinder engine already lauded for its towing and payload performance within its class.
The enhanced performance of the L4B TurboMax engine is attributed to several key engineering modifications. These include the integration of a new turbocharger, a refined fuel injection system, an updated active thermal management system, and redesigned pistons. These advancements were unveiled alongside details of GM's next-generation Small Block engine, underscoring the comprehensive nature of these powertrain upgrades. The forthcoming 2027 Chevrolet Colorado and GMC Canyon promise to deliver a more powerful and responsive driving experience, particularly for those who frequently tow or haul, though final performance verification will come with official testing and production models.
