A new, environmentally friendly auto racing series just got even greener.
Boston Celtics managing partner Wyc Grousbeck and a dozen of his co-owners in the NBA franchise have invested $21 million into Formula E, an all-electric circuit that has already attracted celebrities with environmental interests such as actor Leonardo DiCaprio and billionaire Richard Branson. The series is scheduled to debut in Beijing in September and continue on the streets from Miami to Monaco in a 10-race, Formula One-style championship.
‘‘We aim to help make Formula E a worldwide sensation,’’ Grousbeck said shortly before the deal closed. ‘‘With our upcoming races in the centers of Los Angeles and Miami, we will help showcase the power and promise of sustainable vehicle technology.’’ Full story for BostonGlobe.com subscribers.
