MIVEC: Mitsubishi Innovative Valve timing Electronic Control system.

The dual-intake valve camshaft enables changing between low-speed and high-speed modes, resulting in easy operation from low to high rpms, improving the driving experience when starting from a stop light, merging onto the freeway, or accelerating to overtake another car. In the pursuit of pure driving enjoyment, potentially incompatible goals like fuel economy, environment-friendliness, and clean driving have all been achieved.
