While the industry collectively sighed in disappointment with regards to the new engine’s EPA-estimated fuel economy figures, GM said it believes the engine will make up 10 percent of the truck’s sales mix, Sandor Piszar, Chevy trucks marketing director, told Automotive News (subscription required).
The 2.7-liter turbo-four engine will be standard equipment on all 2019 Silverado LT and RST models. It replaces the 4.3-liter V6 engine as the volume powertrain—the V6 is still available for Work Truck and other lower-end models, however.
Chevrolet has begun production of 2019 Silverado models with the 5.3-liter and 6.2-liter V8 engines, but the fuel-saving turbocharged four-cylinder engine will hit dealerships a little later. The new engine returns an estimated 20 mpg city, 23 highway, and 21 combined. The figures show just a 1 mpg improvement over the older 4.3-liter V6 engine, but GM said buyers should trust real-world driving over the EPA.
“Don’t look at the label,” said Tim Herrick, executive chief engineer of GM’s full-size trucks. “We’re as good or better than them in every step.”
Analysts said the real test will be for potential buyers to see if the smaller engine performs better than the V6 in everyday driving scenarios, which many will hold to a higher regard than the fuel economy numbers. Even with the minor 1 mpg bump, the fuel savings are rather significant when combined with hundreds of thousands of Silverado (and Sierra) sales each year.
And GM is quick to note the 2.7-liter engine makes 310 hp and 348 pound-feet of torque over the 285 hp and 305 lb-ft of torque the V6 engines provides.
We’ll certainly keep a close eye on the turbo-four powered Silverado and Sierra as the roll out to dealerships in the coming weeks.
