Despite viral claims, Toyota hasn't built a water. Toyota's latest breakthrough in sustainable mobility - the world's first water engine. Departing from conventional hydrogen-powered vehicles, this groundbreaking innovation operates at an unprecedented temperature of 2500°C, thanks to its ingenious water-cooled design.
But that's not all - equipped with a special dual injection system, this engine delivers unparalleled efficiency and performance. Mirai combines hydrogen with oxygen from the outside air to generate power, without creating any tailpipe emission besides water, helping propel us into a future of possibilities. This innovation builds on Toyota's deep expertise in hydrogen fuel cell technology, honed over years of research and product development.
With this new internal combustion design, Toyota may bridge the gap between traditional engines and fully electric powertrains, offering yet another route to sustainable transportation. Hydrogen produces only water emissions, plus the fuel-cell trucks are quick. Here's how it works.
Explore Toyota's revolutionary "water engine"-a hydrogen-powered technology driving sustainable mobility. Learn how it works, its benefits, and its role in shaping the future of transportation in 2025. But Toyota told AFP Fact Check that the claim is false.
Experts also pointed out that this concept is extremely inefficient and technically unfeasible. "In a move that will shake up the global auto industry, Toyota has just unveiled a water-powered engine powered by hydrogen created through electrolysis, emitting only water vapor! No lithium. The quest for alternative fuel sources has captivated the automotive industry, and Toyota 's recent patent for a water.
AAP FactCheck - Toyota has not unveiled a car powered by water, despite claims on social media. The automotive industry giant confirmed it has developed hydrogen-powered vehicles that emit water vapour, but it hasn't built a water. Social media has been bubbling with sensational claims: that Toyota has created a car running purely on water.
The truth? While fascinating, the story has been widely misrepresented. What Toyota has actually unveiled is a hydrogen-powered internal combustion engine-and while water plays a role, it.
