"…through 2021, we think that the low hanging fruit, the most cost effective technologies, are really improvements to conventional technologies. We are going to redefine what a conventional vehicle is … there will be continued advances in engines… there will be improvements in transmissions… a lot of road-load improvements… a lot of reduced accessory loads… along with some hybridization. After 2021, we think that we need more electrification, and that is where market signals will be important…. [Honda] will be dedicating 80, 90 if not 100% of the efficiency improvements towards fuel economy."
