“It’s a true honour for Chevrolet to be recognized with the Canadian Green Car Award for the second year in a row; with Volt in 2016, and now the game-changing Bolt EV in 2017,” said Stokes. “Chevrolet is committed to innovation and electrification and we are proud to sell more plug-in electric vehicles in Canada than any other brand.”
