New to the Civic lineup, the Civic HF takes fuel efficiency to higher levels[1].
The Slippery Civic
The new Civic HF has the same smooth, mpg-enhancing shape as all Civics.
The Science of Fuel Saving
The Civic HF also gets the same efficient powerplant as the rest of the lineup, but adds an aerodynamic decklid spoiler and unique alloy wheels with low rolling-resistance tires.
Go Low
To further enhance aerodynamics, the ride of the HF was lowered a bit compared to other Civic models, and special wind-cheating underbody panels were also added.
