The Honda Sport Concept Civic Si, unveiled at the annual Specialty Equipment Market Association (SEMA) show today, is an extensively modified version of the all-new 2006 Civic Si with aggressive exterior and interior styling and a track-tuned suspension.

The wide-body Sport Concept Civic Si (+50 mm) features aerodynamically styled front and rear bumpers with lightweight carbon fiber construction and sleek door styling. Low, aggressive carbon side skirts along with a rear carbon diffuser and a center exhaust outlet accent its ultra-low profile. To enhance high-speed downforce, the Sport Concept Civic Si utilizes an adjustable, two-piece carbon wing spoiler. The vehicle is painted Anniversary White Pearl in celebration of the Civic Si's 20th anniversary.

"The Civic has a legendary reputation as a solid platform for performance and styling customization," said John Mendel, senior vice president of American Honda Motor Co., Inc. "The Sport Concept Civic Si shows Honda's interpretation of future aftermarket trends for the all-new 2006 Civic Si."

An advanced, track-tuned suspension package lowers the Sport Concept Civic Si by 25 mm and enhances the vehicle's handling dynamics with optimized spring rates and firm damping. Brembo brake components on all four wheels feature powerful four-piston calipers and cross-drilled rotors that provide amazing levels of stopping force. Advanced Concept Design wheels (19-inch) incorporate Michelin Pilot Sport II tires (245/35 ZR-19), providing the Sport Concept Civic Si with the ultimate in handling and styling.

Interior modifications focus on the creation of a high-tech, performance-oriented driving environment. The interior features distinctive woven silver wire flooring, custom leather seats with inverted piping and a distinctive driver-oriented red leather cockpit. An "ultra silver" Kevlar R structural brace stretches across the floor of the rear seat area, further reinforcing the Civic Si's already strong body structure. A sweeping multi-function driver display and Honda Satellite-Linked Navigation System is fully integrated into the instrument panel.

The all-new 2006 Civic Si, upon which this concept is based, has been dramatically redesigned with an expressive and futuristic exterior styling. The 2006 Civic Si features a 2.0-liter i-VTEC(TM) 4-cylinder engine with 197-horsepower, 6-speed manual transmission with helical-type limited slip differential and an assortment of the latest technology, making the new Civic Si a true sport compact enthusiast's performance car.

The development of the 2006 model holds an important place in Honda's automotive heritage as it celebrates the 20th anniversary of the Civic Si in America. The Civic Si has always represented the highest levels of performance in the Civic lineup. Beginning with the 1986 Si hatchback model and proceeding through six generations, the Civic Si has always fulfilled a critical role in the performance image of the Civic and Honda.
