DEARBORN, MI – Ford’s ’17 F-150 pickup arriving this fall gets more efficient and capable with a highly revamped second-generation 3.5L turbocharged V-6 and an all-new 10-speed automatic transmission.

Updates to the 3.5L EcoBoost engine, codenamed D35, focus on improving efficiency while reducing weight and engine noise, says Jim Mazuchowski, manager-new V-6 engines, at a media program to reveal the engine and new transmission at Ford world headquarters here.

Improvements boost torque 30 lb.-ft. (41 Nm) to 450 lb.-ft. 610 Nm) that Ford says is class-leading for a V-6 engine – gasoline or diesel. Horsepower remains unchanged at 365.

Engineers achieved the gains in power and efficiency with higher-boost turbos, port fuel injection (in addition to existing direct injection), Ford-first electronically controlled turbo waste gates, weight-saving hollow camshafts fitted with roller-finger follower valvetrains and standard auto stop/start. Overall, the engine is 4 lbs. (1.8 kg) lighter compared with its predecessor.

Mazuchowski says the Borg Warner-supplied turbos feature upgraded turbine wheels made of lightweight Mar-M-247 super-alloy that are more responsive. Boost is up 2.5 psi (.17 bar) to 16 psi (1.1 bar) using the same 51-mm (2-in.) diameter turbine wheels but employing more sharply angled vanes.

The compression ratio now is 10.5:1, up from 10.0:1, although the lower ratio continues for the high-output version of the engine in the F-150 Raptor.

The Raptor engine’s fuel demands in part drove the need to add port fuel injection on top of existing direct injection in the second-generation engine, Mazuchowski says. But the extra fuel-delivery system also allows engineers to shut down the direct-injection system and its mechanical pump at low speeds and under low loads, reducing friction losses and emissions. Employing both systems at start-up cuts cold-start emissions as well.

Ford is awaiting EPA certification before disclosing any estimates of potential fuel-economy gains from the second-gen engine.
