"The Honda Civic MUGEN Si Sedan elevates the already-impressive Civic Si Sedan into new performance territory," said John Mendel, senior vice president of American Honda. "Performance and racing are part of Honda's heritage and the Civic MUGEN Si Sedan along with the rest our vehicles at SEMA demonstrate that passion."

In addition, Honda-customized concept vehicles included the Honda Fit Sport Extreme Concept and Sport Concept CR-V with custom versions of accessory body kits, interior accessories and wheels. A Honda Element-D drift racecar also debuted with a radical powertrain consisting of a 500-horsepower V6 and rear-wheel-drive. Project vehicles built by aftermarket accessory companies on display included numerous Fits, Civics, an S2000 and a customized off-road racing Ridgeline.

Honda's announcements at SEMA coincide with the on-sale date of the new-for-2007 Civic Si Sedan. The Civic Si Sedan embraces the style and performance of the Civic Si Coupe and marks the first time that "Si" performance has become available in a sedan body style. Similar to the existing Civic Si Coupe, the Civic Si Sedan serves as another performance halo for the Civic line-up with a 197-horsepower, 16-valve, DOHC 2.0 liter i-VTEC(R) 4-cylinder engine with an 8,000 rpm redline - all mated to a close-ratio, 6-speed manual transmission and a helical-type, limited slip differential.

Honda Civic MUGEN Si Sedan

The name MUGEN symbolizes Honda performance throughout Asia and around the globe. MUGEN, under license by M-TEC Co., Ltd., of Japan, has been closely associated with Honda for decades in the design and manufacture of racing and premium performance components. The Civic MUGEN Si Sedan draws inspiration from a "Formula Sport" concept, adding an aggressive dimension of performance to the Civic Si Sedan with a track-tuned suspension, aerodynamic body styling and a performance exhaust system. The track tuned suspension, tested at the Twin Ring Motegi racing circuit in Japan, lowers the vehicle by 0.6 inches (15mm) with highly aggressive spring and damper tuning for enhanced handling performance. The full-vehicle aero-package adds a front spoiler and sports grille, side spoilers, a rear diffuser and a rear wing. The lightweight MUGEN forged alloy wheels measure 18x7.5 inches and are shod with high grip 215/40R18 summer tires. The sports exhaust system reduces back pressure from the catalytic converter back resulting in an enhanced power curve. Additional accoutrements include front and rear MUGEN emblems along with a serial number placard on the instrument panel. A spherical 50 mm MUGEN aluminum shift knob replaces the standard aluminum and perforated leather shift knob. Planned for production in a limited quantity of 500 units a year, the Civic MUGEN Si will be available at U.S. Honda dealers starting in spring 2007 with a manufacturer's suggested retail price (MSRP) of less than $30,000 and includes a full factory warranty.
