Toyota and Mazda just announced a new partnership wherein the Japanese automakers will jointly develop electric vehicles. The partnership also includes a forthcoming $1.6 billion assembly plant at an as of yet unannounced location, with production scheduled to ramp up by the year 2021. The plant will create upwards of 300,000 vehicles annually and employ roughly 4,000 U.S. workers, prompting a Tweet from President Trump, who praised the announcement as a “great investment in American manufacturing.” The plant will initially build models of the Toyota Corolla and a new Mazda SUV, with the possibility for EVs sometime in the future. The partnership includes a 5 percent stake in Mazda for Toyota and a 0.25 percent stake in Toyota for Mazda, with the possibility for expansion in the future. Toyota and Mazda will also work together in developing infotainment tech and autonomous driving tech.
