The EcoBoost V6 displaces 3.5 liters and follows the first-generation engine of the same size that launched in 2009. Power is expected to remain at 365 horsepower, but torque increases 30 pound-feet to 450 lb-ft for the basic 3.5-liter EcoBoost. A higher-output version of the engine, said to make at least 450 hp, will be used in the 2017 F-150 Raptor.
The new EcoBoost engine is about four pounds lighter than the outgoing unit. It has direct and port fuel injection, new cylinder heads, and a new valvetrain. The turbos are also new and increase boost from about 14.5 psi to 16 psi.
The 10-speed transmission was developed as part of an agreement with General Motors. Each company will calibrate the unit for its own vehicles and build it in separate factories. GM will launch the 10-speed in the 2017 Chevy Camaro ZL1 late this year. GM is working on a nine-speed transmission as part of the alliance, as well.
All EcoBoost 3.5-liter V6 F-150s will come with the 10-speed transmission. The smaller EcoBoost 2.7-liter engine and the V8 will offer different gearboxes. Ford is spending $1.545 billion to upgrade facilities in Michigan and Ohio to build the new powertrain combination.
