2002 Honda Civic Si Concept

Modified with a prototype GReddy turbocharger for street use, the Civic Si Concept produces 230-horsepower. Underneath, the Civic Si Concept employs a Honda-developed racing suspension with a widened track and high-performance springs, shock absorbers, Brembo brakes, 18-inch wheels and more.

Parts of the body that channel air for cooling and heat exhaustion are constructed of nickel carbon fiber. The interior houses carbon fiber race seats and a Mugen digital display replaces the traditional gauges with a multi-program LCD screen that can convey extensive engine information. An additional Mugen information center with an LCD screen mounted on the center of the instrument panel provides additional on-board diagnostics.

Exterior Modifications: Rally-inspired body kit, 18-inch polished titanium-finish wheels, carbon fiber grill, front intake and rear bumper diffuser, black chrome finish headlights and smoked taillights, high-mounted 2-stage rear wing.

Interior Modifications: Mugen carbon fiber and Kevlar race seats covered in red Alcantera suede with 6-point racing harness, sport 3-spoke steering wheel, aluminum pedals and shift knob, Mugen high performance LCD screen gauge package, center mounted information display.
