GM Testing the Waters of Smaller Engines

The 2019 Chevy Silverado and GMC Sierra 1500 pickups will be the first in a fleet of new full-sized pickup trucks from automaker GMC that will feature a four-cylinder engine option. This will represent a major sea change for some loyal customers. Ford’s success with its v-6 EcoBoost engines may have already proven that a V-8 engine doesn’t have to be the standard. And modern advances in engineering have made smaller engines in larger vehicles a very real option.

The new 2.7 liter, inline four-cylinder will feature what GM is calling Active Fuel Management. This technology will allow the engine to switch over to a two-cylinder mode for “light load conditions.”

The new engine represents a keystone moment for General Motors as it is the first time they will put a four-cylinder engine in a full-size pickup and it is the first engine in a pickup to use the AFM two-cylinder technology.

The new inline four turbo engine is rated at 348 pound-feet of torque and 310hp with an 8-speed automatic transmission. GM hopes to compete in fuel efficiency against Ford’s F-150 that features an aluminum body and V-6 EcoBoost engine.
