Ford announces its all-new 3.5L EcoBoost engine and 10-speed transmission.
The second-generation 3.5-L EcoBoost engine will provide 30 ft/lbs more peak torque compared with the first-generation 3.5L EcoBoost engine, up to a best-in-class 450 ft/lbs for a V6. F-150 remains the only truck in its segment to offer a twin-turbo V6 gasoline engine.
The all-new Ford-built transmission – the first volume-production 10-speed automatic transmission available to consumers from any automaker – will deliver improved acceleration and performance compared with previous six-speed automatic transmissions.
“The Ford truck team lives to serve our hardworking truck customers,” said Raj Nair, Ford executive vice president, product development, and chief technical officer. “The powertrain is the heart of every F-150, and together our all-new 3.5L EcoBoost and 10-speed transmission will give our customers better power, efficiency and confidence.”
More than 20 patents are approved or pending for the innovative powertrain combination.
Second-generation 3.5-liter EcoBoost engine
The new 3.5L EcoBoost engine builds on the success of the 2.7L EcoBoost engine and first-generation 3.5L EcoBoost engine available for the 2016 F-150. Nearly 1 million F-150 EcoBoost engines have been sold to date, with the 2.7L and first-generation 3.5L accounting for approximately 60 percent of F-150 sales.
Ford engineers designed the new 3.5L EcoBoost engine to provide best-in-class torque for a V6 engine, beating gasoline- and diesel-powered competitors. The new engine provides better low-end and peak engine performance, ideal for hauling heavy payloads and towing heavy trailers.
The engine features an all-new, 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. 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 lbs of weight. 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 3.5L 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. 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.
All-new 10-speed transmission
The new 3.5L 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.
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.
An integrated torque converter/turbine clutch also helps shave more than 2 lbs 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.
An integrated electric pump works with the standard Auto Start-Stop system for seamless restarts and improved driving efficiency.
