YOKOHAMA, Japan — Within the span of a month, Toyota Motor Corp. and Nissan Motor Corp. have doubled down on starkly divergent strategies for hybrid and electric vehicles.
 While other global automakers hedge their bets on alternative powertrain technologies, Nissan and Toyota are placing risky wagers that each knows exactly which powertrain will dominate among next-generation green vehicles.
 Nissan aims to be the global leader in EVs. Toyota wants to expand its lead as the world’s top maker of gasoline-electric hybrids.
 On June 9, Nissan released the second of four promised EVs, its e-NV200 battery-powered van.
 Just weeks earlier, Toyota pulled the plug on its own EV program by ending a two-year deal to build electric Toyota RAV4 crossovers with Tesla Motors Inc. When the last RAV4 rolls off the line later this year, the world’s largest automaker will no longer be producing electric cars.
