This is very simple, with no other jokes, just go buy the Toyota hydrogen-fuel-cell Mirai! They'll throw in the first three years of gas for free! Just to be clear, that gas is hydrogen gas. Mirai
To be more specific, here is all the info on the Toyota website about the free fuel, listed as disclosure number 24 (out of 31):
"Complimentary fuel for three years or $15,000 maximum, whichever comes first. The three year period starts on the date of card activation or 90 days after vehicle sale or lease commencement date, whichever is earlier. Fuel card is nontransferable. The Mirai is a hydrogen-powered fuel cell vehicle that must be fueled at hydrogen stations conforming to the latest SOCIETY OF AUTOMOTIVE ENGINEERS (SAE) hydrogen fueling interface protocol standards or laws that may supersede such SAE standards. Refer to the Mirai Hydrogen Stations Locator App in Entune, www.toyota.com, or call Toyota customer service at 800-331-4331 for information on hydrogen fueling stations available to Mirai."
One thing I read was that the word "mirai" means "future" in Japanese, so we'll take their word for it. Whether or not hydrogen fuel becomes the future of the automobile remains to be seen. The MSRP on this model is about $57,500.
