DETROIT — With China's Zhejiang Geely Holding Group now owning a controlling stake in Lotus Cars and investing in the brand, the UK company's tiny but loyal global fan base has reason to cheer. Last year, Lotus recruited veteran Jaguar Land Rover executive Phil Popham as CEO. Since then, Popham, 53, has helped build a product plan that has at least one all-new sports car coming and several more vehicles rumored to be under development.
