Honda 3-Stage i-VTEC Engine

American Honda Motor Co., Inc., will introduce a New Honda Hybrid System in the 2006 Civic Hybrid that features a 3-stage i-VTEC engine that employs Honda's "intelligent" VTEC (Variable Valve Timing and Lift Electronic Control) system to provide three stages of valve timing (low-rpm, high-rpm and cylinder idle mode), combined with a significantly more compact and efficient Honda IMA (Integrated Motor Assist) system.
