Pretty much all the major automakers have dabbled with hydrogen FCVs in some way or another, including Nissan. Some (Nissan included) have had working prototypes for years. When I went to Alt Car Expo in 2012 (https://web.archive.org/web/20120901161 ... icles.html
), I test drove FCEVs from Honda (Clarity FCX), Mercedes (B-Class), Kia, Toyota (was a Highlander), and even Nissan (pretty sure it was an X-Trail). The Nissan one IIRC was on loan from Coca Cola. I don't recall if it was being leased to or just loaned for free to Coke. The ride along guy was from Nissan's Sacramento office. I recognized some of the interior bits from other Nissans I had, to which the Nissan guy confirmed.
The Honda and Mercedes in question were being actively leased to So Cal folks.
I've driven an Equinox FCV at Detroit Auto Show in Jan 09.
I've seen Nissan and others offer FCV test drives at Tokyo Motor Show a few years ago, at least from the info online.
