We’re not sure exactly when we jettisoned the active air dam on our 2021 Ford F-150 Limited Hybrid — likely after hitting road debris over the summer — but we’ve been driving around without the aerodynamic-enhancing feature for some time now. The active air dam deploys at vehicle speeds above 40 mph, depending on the selectable drive mode. It lowers from behind the fixed front splitter to increase aerodynamic efficiency up to 4%, according to Ford Product Communications Director Mike Levine.

Even though our long-term F-150 has the available hybrid powertrain, the active air dam is standard on all 2021 F-150s, regardless of powertrain. It seems entirely possible that owners might not even know if it’s been ripped off if they encounter a similar situation.
