A step up in intelligent engines that adds VTC (Variable Timing Control) to VTEC (Variable Valve Timing and Lift Electronic Control System), further raising both power output and fuel-efficiency.
Honda's original Variable Valve Timing and Lift Electronic Control System that achieves both powerful motoring and high fuel-efficiency.
i-VTEC Variable Cylinder Management (VCM) System
Intelligent VTEC system that switches between combustion in all six cylinders and just three cylinders of a V6 engine. This yields high power output and torque together with excellent fuel economy.
i-DSI (Dual & Sequential Ignition)
An intelligent system that controls two sequentially igniting spark plugs per cylinder to enable faster combustion at all engine speeds. This achieves a dramatic improvement in fuel efficiency.
