As Lewis Hamilton and co. head off for a well-earned break , F1's electric cousins are gearing up for another action-packed eight months of all-electric racing. Formula E's fourth season kicks off with two races in Hong Kong this weekend (Dec 2/3) where arch rivals Sebastien Buemi and reigning champion Lucas di Grassi will lock horns once again. Last year's championship went down to the wire, with di Grassi prevailing at a drama-fueled final race weekend in Montreal in July. "You never know what's going to happen," Mahindra Racing driver Nick Heidfeld told CNN. "After a few races you think you might know who's gonna win, but usually it's not the case."
