Despite previous indications that Toyota would begin selling a fuel cell car by 2015, it’s thought that the Japanese vehicle manufacturer may be pushing ahead with its plans sooner than expected.

Toyota said in January that it would begin selling a fuel-cell car by 2015, according to a report by The New York Times.

However, the US newspaper also notes that the dollars-and-cents imperatives of California’s Zero Emission Vehicle (ZEV) mandate may now move that timetable forward, to late 2014.

The US’ Department of Energy has recently proposed the elimination of funds for hydrogen fuel cell motor vehicles and when asked about the company’s plans in light of this, Toyota spokesman John Hanson reportedly responded, “Toyota is planning to go ahead with its program in certain world markets by 2015, if not sooner.”

“We’re shooting for 2015, but it could happen sooner than that. So much of what happens is directly related to the California ZEV mandates — they’re followed by at least 14 states, and they affect nearly half of the cars on the market in the United States,” he explained.

“Phase IV of the mandates covers model years 2015 through 2017, so that means we could begin complying in late 2014.”
