Ford’s F-150 MY-16 and MY-17 models are now being offered with an updated 3.5-L EcoBoost V-6 engine that offers an improved EPA over the previous generation engine, which is mated with an all-new 10-speed automatic transmission.

For the 2017 model, EPA-estimated city, highway, and combined fuel economy is 18/25/21 mpg for the 4x2 model and 17/23/20 mpg for the 4x4. The 2016 4x2 offers and EPA-estimated 17/24/20 mpg, and the 4x4 is at 16/22/18 mpg, according to the automaker.

This second-generation 3.5-L EcoBoost engine delivers 375 hp and 470 lb.-ft., a gain of 10 hp and 50 lb.-ft. over the first-generation engine.

The new 10-speed automatic transmission available for 2017 F-150 4x2 and 4x4 models optimizes engine power and torque ranges, with closer ratios between gears and patented hydraulic controls. The powertrain combination provides better low-end and peak performance, according to the automaker.

The all-new 3.5-L EcoBoost includes a new twin-port and direct-injection fuel strategy, lighter and stronger crank and valvetrain components, redesigned twin turbocharger with electronic wastegate, and redesigned valvetrain and variable-displacement oil pump.

A new adaptive shift-scheduling algorithm monitor more than a dozen powertrain and driver control signals in real time. Additionally, a high-speed one-way clutch allows for non-sequential shifting, according to the automaker.

Weight savings play a key role in improved shifting performance. The 10-speed gearbox offers an integrated torque converter/turbine clutch that shaves more than two pounds, while reducing the packaging footprint, according to the automaker.

DUI or Driving Under the Influence (sometimes called DWI or Driving While Intoxicated) is a criminal offense in most states (most countries, actually). The substance can be alcohol or drugs, which is why it's not merely called "drunk driving" anymore.
