Not sure if that's similar to what RTD has ordered but BYD Co. will manufacture the buses in China and assemble them in California. I didn't make the connection until I looked it up but Warren Buffet is an investor; I do recall seeing the news coverage of his trip to China. The Hertz bus is being used at LAX.
BYD Co. is the world’s largest producer of electric buses and has sold more than 5,000 of them globally, according to the company. Photographer: Brent Lewin/Bloomberg
