Honda has a Hybrid Automotive Engine That Uses Less Rare Earth Metals

Honda pledged to reduce its use of rare earth metals a decade ago, and the automaker took another step towards that goal this week. It unveiled its new hybrid motor that was co-developed alongside Daido Steel, another Japan-based company. The new motor doesn't use heavy rare earth metals like dysprosium and terbium, instead relying on magnets from Daido Steel that cost 10 percent less and weigh 8 percent lighter than the previous components. In fact, the automaker is the first to develop a hybrid motor that doesn't use the heavy metals. Honda says the new engines will reduce its reliance on the pricey rare earth metals that are primarily supplied by China.
