The Silverado’s propulsion lineup is strengthened and streamlined for the new 2022 models, starting with significant enhancements to the 2.7L Turbo High-Output engine. It leads with more torque than any base engine in its class and has a maximum trailering rating of 9,500 pounds in a two-wheel drive configuration12.

A new, more rigid cylinder block casting is the foundation for the refined 2.7L Turbo High-Output engine and it’s complemented with a 30-percent-stiffer crankshaft. The engine maintains its fully forged bottom end as well as technology used in diesel engines to deliver on truck durability.

These enhancements enabled engineers to reduce noise and tune the engine for greater torque production, particularly in the usable low-mid rpm range. Maximum torque is GM-estimated at 420 lb-ft (569 Nm), over a 20-percent increase compared to the current engine.

There also have been shift scheduling revisions of the 2.7L Turbo High-Output engine’s complementing eight-speed automatic transmission to offer smoother shifting, along with quicker downshifts, for a greater feeling of refinement and power on demand.
