GMC revealed yet another 2019 Sierra variant heading to production later this year in the 2019 Sierra Elevation. But, with the announcement came an important piece of news: GMC confirmed the new 2.7-liter L3B turbocharged four-cylinder engine.
Although it’s not a shocking confirmation, it’s the first time GMC has mentioned the 2.7-liter turbo-four with the 2019 Sierra. Previously, Chevrolet announced the engine will replace the 4.3-liter V6 engine in volume models like the LT and RST trims.
We don’t know exactly what other Sierra variants will feature the new engine, but GMC confirmed the Elevation model will arrive with the 310 horsepower powerplant as standard. The 5.3-liter V8 engine with dynamic fuel management will be optional.
GM has said in the past that the four-cylinder engine was developed for truck duty, first and foremost. Thus, the 348 pound-feet of torque comes on between 1,500 rpm and 4,000 rpm. The engine also weighs almost 400 pounds less than the V6 engine it replaces. Additionally, the 2.7-liter L3B engine introduces active fuel management for an inline-four engine, a first for General Motors.
As the pickup approaches production, we expect GMC to break down exactly which trims will feature the 2.7-liter turbocharged four-cylinder engine. Stay tuned to GM Authority for the latest.
