The Toyota Mirai is a pretty odd-looking car but underneath the skin, it houses one of the most advanced powertrains available in a production vehicle. We are referring to the Mirai's hydrogen fuel cell, which converts hydrogen into electricity, emitting only water vapor in the process. This idea could essentially eliminate greenhouse gas emissions from passenger cars without requiring owners to charge at home where electricity is typically generated from burning coal.

Toyota has already partnered with Kenworth to put a hydrogen fuel cell into a semi-truck that's been doing service around Los Angeles. Now the Japanese automaker has partnered with Hino Motors to jointly develop another heavy-duty fuel cell truck.
