2017 Ford F-150 to Include New 3.5-Liter Engine and 10-Speed Transmission: THE SHOP News

Ford will deliver more torque and better acceleration to 2017 F-150 customers with the all-new 3.5-liter EcoBoost engine and 10-speed transmission.

The new second-generation 3.5-liter EcoBoost engine will provide 30 lb.-ft. more peak torque compared with the first-generation 3.5-liter EcoBoost engine, up to 450 lb.-ft. overall, according to the company. F-150 remains the only truck in its segment to offer a twin-turbo V6 gasoline engine.

The new Ford-built transmission is the first volume-production 10-speed automatic transmission available to consumers from any automaker, according to the automaker. The transmission will deliver improved acceleration and performance compared with previous six-speed automatic transmissions.

Second-Gen 3.5-liter EcoBoost engine

Ford engineers designed the new 3.5-liter EcoBoost engine with better low-end and peak engine performance, ideal for hauling heavy payloads and towing heavy trailers, according to the company.

The engine features a Ford-first dual-direct and port fuel-injection system. Two injectors per cylinder—one mounted in the intake port where air enters the cylinder and one positioned inside the cylinder—work together to improve power output, efficiency, and emissions.

All-new turbochargers deliver more boost thanks to improved twin turbos and a lighter turbine wheel, according to Ford. The new turbos work seamlessly with Ford-first electrically activated wastegates, enhancing operating efficiency. Light-weighting the turbine wheel—by making it out of high-temperature super alloy Mar-M-247 developed by the aerospace industry—improves responsiveness.

Ford’s commitment to continuous light-weighting to improve performance also is evident in the hollow camshafts in the all-new roller-finger follower valvetrain that help save up to 4 pounds of weight, according to the automaker. The valvetrain also features more durable intake and exhaust valves, and hydraulic valve-lash adjusters that optimize engine durability over the life of the truck.

The new 3.5-liter EcoBoost engine provides Auto Start-Stop as a standard feature, helping customers save fuel, though actual fuel savings vary depending on driving patterns. The technology also contributes to a reduction in CO2 emissions due to decreased idle times, according to Ford. Auto Start-Stop is specially tuned for truck customers, shutting off the engine when the vehicle is at a stop – except when towing or in four-wheel-drive mode.

New 10-speed transmission

The new 3.5-liter EcoBoost engine will be paired with an all-new 10-speed transmission for the 2017 F-150.

The transmission delivers improved acceleration and performance compared with previous six-speed automatic transmissions, thanks to optimized wide-span gear spacing, coupled with drag-reduction actions. Three overdrive gears and a wider ratio span enable lower-numerical rear-axle ratios to help improve fuel efficiency at highway speeds, while maintaining best-in-class towing, according to Ford.

Weight savings play a key role in improved shifting performance. The 10-speed transmission uses advanced materials and alloys to save weight, and it is the first Ford gearbox that does not use cast-iron components, according to the company.

An integrated torque converter/turbine clutch also helps shave more than 2 pounds of weight, while also reducing the packaging footprint.

Smarter shift logic helps 2017 F-150 customers tow with improved confidence using tow/haul mode. All-new real-time-adaptive shift-scheduling algorithms monitor more than a dozen powertrain- and driver-control signals to ensure the right gear at the right time for an engaging driving experience, including in sport mode, according to Ford. An integrated electric pump works with the standard Auto Start-Stop system for seamless restarts and improved driving efficiency.
