Perspective Shift: Greener Cars From Treehugger

This image was lost some time after publication.

This week at Treehugger: The Smart Crosstown hybrid and other Smart concept cars (diesel-hybrid, compressed natural gas, electric, etc). A Honda spokesman explains why Honda keeps the Insight hybrid around despite slow sales (hint: It has to do with the Toyota Prius). Speaking of which, the Prius began production in China and Toyota is once ahead one step ahead of its rivals. The famous London double-decker red buses can be turned into homes, Volkswagen gives the press a road test in its EcoRacer and BMW is developing a steam-gas hybrid engine.
