2007 Honda Accord HF-S Concept

(from Honda Press Release)  Honda Accord Coupe HF-S Concept

Honda Access America, Inc., Honda's U.S. accessory development team designed and built the HF-S Concept to demonstrate how the customized use of technology could allow vehicle owners to fine-tune performance while adding their own senses of style. Key exterior and conceptual powertrain modifications represent functional performance and driving-experience enhancements.
Unique LED driving lights, placed on the fore-most corners, wrap around the front of the bumper providing increased visibility both forward and side for the driver while also creating a unique appearance. The shape of the front bumper is designed to create a vortex effect to enhance high-speed aerodynamics and engine cooling. On the sides of the vehicle, the shape of the carbon fiber panels decreases negative speed force around the wheel arches. The rear bumper diffuser is designed to reduce drag. The trunk spoiler is a prototype design engineered for high-speed down-force. The metallic color of the exterior is accented by Cadmium Orange Pearl - a color derived from super-heated metal. The use of this color for the brake calipers, badges, grille accent, and interior details underscores the vehicle's high-performance appearance.

Key to the concept is the use of technology to electronically customize throttle response, suspension settings, steering boost, and traction involvement to the driver's taste. Additionally, the exhaust is a two-stage design. It is engineered to be exceptionally quiet during relaxed cruising, and provide elevated levels of performance in high performance driving situations.
