<human>:  Why is the Toyota Mirai Fuel cell so expensive?
<bot>: The Mirai is the first mass-produced hydrogen fuel cell vehicle, and it is priced accordingly. However, the price is not so bad when compared to other types of cars. The Mirai costs $57,000, which is about the same price as a Tesla Model S. The Mirai is also expected to be cheaper than the internal combustion engine cars that it is replacing.
