The way manufacturers are currently going is kind of disappointing. I think there will be a larger increase in cam phasing before lean burn is brought back. It's hard to find a car now that doesn't have cam phasing. Personally it seems like band aid after band aid after band aid. While the technology increases the cost of operation goes up. Some of these timing belts and chains take an intricate installation process due to the phasers. If a phaser goes bad it may cost from 600-1000+ to get it fixed. How much gasoline will 600 bux buy you?
