It may currently you cost you $849 a month to lease a Mercedes-Benz B-Class F-Cell (one of the few hyrodgen-fueled vehicles currently available to consumers), but Daimler says that cost will come down considerably in the next few years. Speaking with Automotive News, Daimler's Herbert Kohler said that by 2015 he expects a "fuel cell car will not cost more than a four-cylinder diesel hybrid that meets the Euro 6 emissions standard," which would seemingly place it in a race with Toyota and its promise of a $50,000 hydrogen-powered sedan. What's more, Kohler also said that he expects fuel cell vehicles to actually be cheaper than comparable electric vehicles within the next few years, and he said that Daimler is hoping to bring a "four-digit-number" of fuel cell vehicles to market by 2013 or 2014.
