Volvo has announced the V60 is now for sale and is pushing new promotional videos like this one that emphasize safety and low long-term costs — visit fuel stations just once a month. Only 40 views so far:

Peugeot also has announced a diesel-hybrid 508 RXH sports wagon (in brown, of course).

Marketed in France in 2011, and then the rest of Europe by the end of the year, it appears to be based on the diesel-hybrid technology developed for racing.

Peugeot’s diesel-hybrid version of its 908 sportscar underwent its first track test at Estoril, completing more than 300km in the hands of Nicolas Minassian, Stephane Sarrazin and Alexander Wurz.

The barriers to adoption of this far superior technology are price and availability. But if consumers factor in the huge time saving from visiting a gas station half as often or less…the cost concern evaporates. If they are sold in America the only question that remains will be whether they can build cars fast enough (pun not intended) to meet demand.
