A quick check of the 2016 GM VIN decoder reveals that the LKW, the 2.5L Ecotec 4-cylinder engine, is gone. The 2016 Impala order guide shows it as being replaced by the LCV, which is the same engine less the iVVL system, and the 2016 Malibu Limited (which is the current car, but likely only available to fleets) will also drop the LKW in favor of the LCV.

My question is, why? The system was only introduced about a year or so ago, so I’m having a hard time believing that reliability issues crept up in such a short time. This would also seem to indicate that GM is not going to use it anymore, which I find very odd. Does anyone have info? I realize these cars aren’t exactly popular with Jalops, but the iVVL system is a smart idea IMO.
