As other automakers plan battery-powered SUVs and trucks, Toyota Motor Corp.’s vision for the future of driving remains a hydrogen-sipping sedan.

The Japanese behemoth will begin sales late next year of the second-generation Mirai, its fuel cell-powered four-door, and ramp up annual production by tenfold from the current model. Toyota’s bet that it can position a hydrogen sedan for more of a mass market flies in the face of rivals wagering on putting batteries into the bigger-bodied vehicles consumers are buying.
