The hydrogen-powered Toyota vehicle is which model?

• A. Sienna
• B. Mirai
• C. Prius Prime
• D. Sequoia

Answer: (B)

Hydrogen-powered models from Toyota are fuel-cell electric vehicles that generate electricity onboard from hydrogen and oxygen, emitting only water at the tailpipe. The Toyota that uses this technology is Mirai, a dedicated hydrogen fuel cell vehicle that stores hydrogen in tanks and powers an electric motor. The other options run on conventional gasoline or use batteries charged by plugging in (or through hybrid operation) rather than hydrogen fuel cells: Sienna is a hybrid minivan, Prius Prime is a plug-in hybrid, and Sequoia is a large SUV with conventional or hybrid powertrains. So the hydrogen-powered Toyota vehicle is Mirai.
