To gearheads, the “Tripower” name stands for three two-barrel carburetors stationed atop a Pontiac V8 engine. In 2018, General Motors has a different idea for Tripower.
The automaker announced it will bring the Tripower name out of retirement for the 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500 pickups. However, the trucks’ Tripower engines will refer to the 2.7-liter L3B turbocharged four-cylinder engine. This time, Tripower is all about fuel efficiency, not big power.
Automotive News reported Tuesday that Mike Anderson, GM executive director of global transmission and electrification hardware engineering, said Tripower defines a trio of fuel-saving technology. Specifically, in the 2.7-liter turbo-four engine, it stands for cylinder deactivation, active thermal management and intake valve lift control.
Each technology contributes to the 2.7-liter engine’s fuel economy figures which Chevrolet hasn’t disclosed yet. The engine will replace the Silverado and Sierra’s 4.3-liter V6 engine as the volume engine and is rated at 310 horsepower and 348 pound-feet of torque.
The Tripower name was last used on the Pontiac GTO in 1966. Production of the now coveted Tripower engines began in 1957 and ended with a 389-cubic-inch V8 making 360 hp.
