GM's 2027 Silverado and Sierra pickups to feature enhanced TurboMax engine

General Motors is updating the 2.7-liter TurboMax engine for the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500, with increased power and torque for improved performance.

General Motors is preparing a new generation of full-size pickup trucks, the Chevrolet Silverado 1500 and GMC Sierra 1500, expected for the 2027 model year. Alongside updated body designs and redesigned interiors, these vehicles will see changes to their engine lineup.

One of the key updates will be a modernization of the 2.7-liter TurboMax gasoline engine. According to sources, the powerplant will receive increased power and torque, though exact figures have not yet been disclosed.

Currently, the turbocharged four-cylinder engine produces 310 horsepower and 583 Nm of torque. This already makes it one of the most capable base engines in the full-size pickup segment, comparable to some naturally aspirated V8s.

The TurboMax engine serves as the base gasoline unit in the Silverado 1500 and Sierra 1500. It first appeared in 2019 as part of GM's strategy to shift toward more compact turbocharged engines with high torque and improved fuel efficiency. The design features an aluminum block and cylinder head, direct fuel injection, and a twin-scroll turbocharger. It also employs active thermal management and variable valve timing.

The updated motor will be part of future Silverado and Sierra models and is likely to be used in new vehicles from 2026 onward, as well as in subsequent generations of the automaker's pickups.
