The turbocharged four-cylinder engine set to power some 2019 Chevrolet Silverado and GMC Sierra pickup trucks will run on all four cylinders or on as few as one, depending on driving demands. The 2.7-liter turbocharged engine can deliver full power – 310 horsepower and 348 pound-feet of torque – to accelerate or haul loads, but can run on just one cylinder under low-load, steady-state cruising, coasting, and on downhill grades. General Motors will continue to offer Silverados equipped with six- and eight-cylinder engines. Fuel efficiency, towing and payload numbers have not yet been released. Pricing, fuel economy and other statistics will be announced closer to launch in the fall.
