Yup. It really needs to be stressed that hydrogen-powered cars are a mix of compliance and "halo" vehicles - vehicles designed to showcase the bleeding edge of what a manufacturer can do. Halo vehicles are usually focused on performance, and any car enthusiast can tell you that they can be a nightmare of compromises, unique-to-the-model low-volume (and thus very expensive) parts, and so on. Enough to look good and work well for the press and the first owners. The high development costs are a write-off, but that doesn't mean they'll eat the cost of the parts outside warranty. For example, the first Audi RS6 had a biturbo V8 shoved into a mid-size engine bay. The battery was relocated, almost as an afterthought, to sit smack dead-center in the back of the trunk, just bolted down in a carpeted box.
