wikipedia: "The two spark plugs in each cylinder can fire either sequentially or simultaneously, enabling more efficient burning during lean-burn mode and more often lean-burn operation. The engine can operate at a lean 22:1 air-to-fuel ratio more than 60 percent of the time on a flat road.
"The VTEC cylinder-idling system closes the valves in three of the four cylinders when the car is decelerating, reduces the power lost to the engine by 50 percent, and allows the IMA to extract more electrical energy during braking."
Well.
