Coming Soon: Hydrogen and Electric Vehicles From Toyota

Toyota plans to begin selling a hydrogen-powered car in 2015, and a two-seater electric vehicle in 2012, the company announced Tuesday at the North American International Auto Show.

But he said Toyota had to proceed. “We will run out of any alternative strategies if the oil supply diminishes,” Mr. Takimoto said. “Oil consumption will increase, and the supply could become unstable.”
