From its inception at the turn of the last century, the car has undergone a massive number of changes – except for its fuel.
Japanese car giant Toyota is hoping that the launch of its hydrogen fuel cell powered Mirai, which went on sale in Japan in late 2014 and will be available in the United States later this year for $57,000, will mark the beginning of the end of our reliance on fossil fuels.
"Gasoline will be depleted sometime in the future, and using gasoline causes issues such as carbon dioxide (emissions) and global warming," Yoshikazu Tanaka, chief engineer at Toyota, told CNBC's Sustainable Energy.
"We need to leverage alternative energy in order to response to environmental issues."
According to the Institution of Mechanical Engineers, it is estimated that there are 1.3 trillion barrels of proven oil reserves remaining in major oil fields, and "by 2040, production levels may be down to 15 million barrels per day – around 20 percent of what we currently consume."
How then, does the Mirai – Japanese for 'future' – work? Hydrogen is pumped into the car and stored in its fuel tanks. Air flows into the vehicle via an "intake grill" on its front, and then mixes with the hydrogen in a fuel cell stack. Electricity is created and the vehicle is powered. Toyota say that the only by-product of this process is water.
