Ford is revamping its F-150 engine lineup for 2018 to offer a more efficient V-6 and more powerful V-8 in a lineup that will also include a diesel option for the first time, the company has announced.

For 2018, a 3.3-liter V-6 adds dual port and direct-injection technology to provide more power and torque (plus eight to 290 hp and plus 12 to 265 lb.-ft.) than the outgoing 3.5-liter V-6, along with a projected improvement in fuel economy. This base engine provides a 5% better power-to-weight ratio compared to the 2014 F-150 powered by the 3.7-liter V-6, according to Ford.

The new 2.7-liter EcoBoost increases torque by 25 lb.-ft. to 400 lb.-ft. Horsepower remains at 325 hp. The engine will now be paired with Ford's 10-speed transmission.

The F-150's 5.0-liter V-8 adds 10 horsepower to 395 hp and increases torque by 13 lb.-ft. to 400 lb.-ft. The engine will also be paired with the 10-speed automatic.

Power ratings for the 3.5-liter EcoBoost (375 hp and 470 lb.-ft.) and 3.5-liter high-output EcoBoost (450 hp and 510 lb.-ft.) remain unchanged.

Ford will also offer a 3.0-liter Power Stroke V-6 diesel in the spring of 2018. Ford hasn't released power ratings for that engine yet.
