This thing is no concept, no prototype. It's a finished automobile (and a beautifully finished one at that) that'll be available for three-year leases in Southern California for $600 per month. The lease amount doesn't reflect the car's production cost, of course; instead, it's meant to filter the applicant list to the car's eventual audience -- specifically, households earning $150,000 per year, with presumably well-educated occupants. Before the test drive, we attempted to press Honda on the FCX Clarity's production numbers or even its guess at how many cars the Southern California hydrogen infrastructure could support in the near-term, but no such luck. Although Honda is proving itself to be unbelievably confident to raise the stakes in the hydrogen car game to such a height, it obviously doesn't want to be held to any specific figures should things unexpectedly unravel.

On the road, the FCX Clarity drives quite similarly to its concept predecessor, but it's a breathtaking architectural and engineering advance over the 2005 version of the technology Honda's previously let loose on select municipalities and notably to the Spallino family in Redondo Beach, California.
