Tesla and Toyota are fighting over the best way to power an electric car

Toyota just announced that its new Mirai hydrogen fuel-cell sedan is now the longest-range zero-emission car in the world.

It can do an EPA-estimated 312 miles on a single tank of the most abundant element in the universe.

Tesla, meanwhile, says that owners can drive a Model S sedan for a mere 270 miles on a single charge.

The battle lines are drawn, because at base, both the Mirai and the Model S are electric cars — they just create the electricity using different means.

For Toyota, the Mirai is a successor to the Prius, which brought widespread gas-electric hybridization to the masses. Fuel cells use hydrogen to generate electricity, which charges the car's batteries.

“The Mirai is now poised to usher in a new era of efficient, hydrogen transportation,” said Jim Lenz, Toyota's North American CEO, in a statement.

Tesla CEO Elon Musk, by contrast, isn't a big fan of fuel cells. He infamously referred to the power generation technology as "fool cells" in 2013. In fact, the Silicon Valley mogul went as far as calling the technology "so bullshit."

In response, Toyota released a commercial earlier this year — aimed at fuel-cell doubters such as Musk — explaining that the Mirai can literally run on bullshit.
