2027 Chevrolet Colorado and GMC Canyon Gain Upgraded Engine

Fresh off announcing changes to its 2027 full-size truck engine lineup, General Motors is also giving its midsize pickup duo a substantial power boost for the 2027 model year.

According to order guide details, both the Chevrolet Colorado and GMC Canyon will trade their previous 310-horsepower setup for GM’s upgraded 2.7-liter turbocharged four-cylinder engine (RPO code L4B). The enhanced TurboMax mill jumps to 350 horsepower and 455 lb-ft of torque—a healthy bump over the outgoing L3B engine.

Hardware Upgrades and Transmission Details

The upgraded 2.7-liter inline-four is the same base engine making its way into the updated full-size 2027 Silverado 1500 and Sierra 1500. Engine enhancements include a re-engineered turbocharger, redesigned pistons, upgraded fuel injection, revised active thermal management, and hardware tweaks aimed at reducing noise, vibration, and harshness (NVH).

However, the midsize trucks diverge from their half-ton siblings behind the flywheel. While the Silverado and Sierra pair the new L4B engine with a 10-speed automatic transmission, the Colorado and Canyon will retain an updated version of their existing eight-speed automatic.

Despite the power increase, towing limits remain unchanged across the lineup, with standard trucks capable of dragging 7,700 pounds, ZR2 and AT4X trucks can handle 6,000 pounds, while Bison and AEV Editions drop to 5,500 pounds.

Challenging the Midsize Segment

With 350 horsepower and 455 lb-ft of torque, GM’s midsize trucks position themselves competitively against key segment rivals. The output places the Colorado and Canyon above the Toyota Tacoma's i-FORCE MAX hybrid (326 hp), while sitting just under the high-performance Ford Ranger Raptor's twin-turbo V6 (405 hp).

Alongside the powertrain update, the 2027 Colorado gains fresh exterior paint colors, minor equipment revisions for the ZR2, and an available power-adjustable front passenger seat. The 2027 Canyon receives new wheel designs, expanded interior connectivity features, and updated trim options. Production for both trucks is slated to begin this fall at GM’s Wentzville Assembly plant in Missouri.
