WrightSpeed founder Ian Wright was one of the original founders of Tesla Motors. He severed his relationship with the company after Elon Musk took control of the company. Wright disagreed with Musk’s “let’s build a really expensive premium electric car first and worry about building electric cars that are affordable later” strategy. In fact, Wright wasn’t that interested in building passenger cars at all. His primary focus was on raising the average fuel economy of heavy trucks and buses. Those vehicles may not be glamorous, but they burn up millions of gallons of diesel fuel every year. More diesel means more emissions. Wright thought he had a better idea.
