Other F-150 aerodynamic efficiency improvements include:
- Flush-mounted windshield eliminates need for molding that would disrupt smooth airflow
- Tailgate top is designed to act as a spoiler, giving air that flows off the roof a place to land before smoothly trailing off – reducing turbulence behind the truck
- Cargo box is narrower than the cab, with no reduction in box volume, which enhances airflow, while a trim piece prevents air from getting trapped between cab and box
- Rear corners including taillamps are precisely angled so air breaks off cleanly – reducing turbulence behind the truck
- Duct under headlamp channels air through to the wheelhousing and reduces the wake generated from the wheel
