Designed as an "Advanced Personal Compact," the next-generation Si will incorporate flowing bodywork, a steeply angled windshield, and wide stance to suggest stability and forward motion. The new Si will be the fastest and most powerful Civic offered in its twenty-year history. The 2006 Civic lineup, launching this fall, will include a 4-door Sedan, a 2-door Coupe and Si Coupe, an even more fuel efficient Civic Hybrid and a natural-gas powered Civic GX.

The Civic Si Concept builds on its performance heritage with a 200-horsepower, 16-valve, and DOHC i-VTEC engine with an 8,000-rpm red line, mated to a close ratio 6-speed manual transmission. Helping to put all that power to the ground is a helical-type limited slip differential for improved launch traction and cornering performance.
A 200-horsepower 16-valve i-VTEC engine powers the 2006 Si. Honda sources indicate that next-generation i-VTEC technology will have significant gains in performance and fuel economy. A six-speed transmission will give drivers manual control of shift points up to the engine's redline of 8000 rpm, and a helical-type limited-slip differential will enhance traction and cornering ability.

The Si Concept includes performance features such as 18-inch cast aluminum wheels with 225/40R high performance tires, and 4-wheel disc brakes with large cross-drilled brake rotors. "The 2006 Civic Si Coupe will be the most powerful, fastest and fun-to-drive Si we've ever put on the street, and the Civic Si Concept sets the direction in terms of its styling, package and performance," said John Mendel, senior vice president of American Honda. "It's part of a new family of Civic vehicles that build on the already class-leading values of the Civic in terms of safety, styling, performance and fuel efficiency."

This new production Civic Si Coupe will serve as the performance leader for the 2006 Civic model lineup, which will be completely redesigned. The 2006 Civic will feature more emotional styling, enhanced performance, and the latest generation of "intelligent" i-VTEC engine technology.
