    Hi mga Mitsu Gurus, ask ko lang which is better in performance on the latest Mitsu engines : MIVEC (Mitsubishi Innovative Valve Timing Electronic Control) or GDI (Gasoline Direct Injection) assuming the same engine displacement.

    MMC is no longer focusing on GDI engines due to its lack of compatbility with various fuel requirements. it is either because of MMC lack of research or lack of capital to reaserch further. it would have been nice as this will aid in fuel economy. also other car brands have been successful with this- like Audi for example. GDI focuses on fuel delivery that directly sends fuel to the combustion chamber.

    MIVEC is the other way around. its compatibility reached more countries including the US and the Philippines to name a few. MIVEC's approach is different as this focuses more on today's trend of Variable Valve Timing that will aide fuel economy (example: 4G64 vs 4G69 ad 4B12)

    It is up to MMC now to create an engine combo of MIVEC+GDI to create a truly eco friendly yet power oriented engine. If ever they did, then I'm sure they are finalizing it. Good luck to MMC

    Meron ding nilabas na MIVEC na matipid sa gas compared to the usual MIVEC engine.

    Source: http://en.wikipedia.org/wiki/MIVEC

    MIVEC-MD
    In the early years of developing its MIVEC technology, Mitsubishi also introduced a variant dubbed MIVEC-MD (Modulated Displacement), a form of variable displacement. Under a light throttle load, the intake and exhaust valves in two of the cylinders would remain closed, and the reduced pumping losses gave a claimed 10–20 percent improvement in fuel economy. Modulated Displacement was dropped around 1996.
