The real problem is the absence of a systems analysis of a hybrid vehicle. The diesel is being treated as "blessed" or a "magic technology" without thinking about the whole vehicle profile. In fact, it is the blessing of a particular engine technology and failure to do a complete systems analysis that spells doom for many of the faux hybrids announced and coming on market.

There is a very simple relationship, the ratio of traction power to ICE power that tells whether or not a particular vehicle will be a successful hybrid or a 'greenwash' hybrid. Understand, I have no problem with manufacturer's trying to sell 'greenwash' hybrids but I won't put my money in them.
